+ Basic Installation
+ ==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+ various system-dependent variables used during compilation. It uses
+ those values to create a `Makefile' in each directory of the package.
+ It may also create one or more `.h' files containing system-dependent
+ definitions. Finally, it creates a shell script `config.status' that
+ you can run in the future to recreate the current configuration, a file
+ `config.cache' that saves the results of its tests to speed up
+ reconfiguring, and a file `config.log' containing compiler output
+ (useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+ to figure out how `configure' could check whether to do them, and mail
+ diffs or instructions to the address given in the `README' so they can
+ be considered for the next release. If at some point `config.cache'
+ contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+ called `autoconf'. You only need `configure.in' if you want to change
+ it or regenerate `configure' using a newer version of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes a while. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ Compilers and Options
+ =====================
+
+ Some systems require unusual options for compilation or linking that
+ the `configure' script does not know about. You can give `configure'
+ initial values for variables by setting them in the environment. Using
+ a Bourne-compatible shell, you can do that on the command line like
+ this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+ Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+ Compiling For Multiple Architectures
+ ====================================
+
+ You can compile the package for more than one kind of computer at the
+ same time, by placing the object files for each architecture in their
+ own directory. To do this, you must use a version of `make' that
+ supports the `VPATH' variable, such as GNU `make'. `cd' to the
+ directory where you want the object files and executables to go and run
+ the `configure' script. `configure' automatically checks for the
+ source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+ variable, you have to compile the package for one architecture at a time
+ in the source code directory. After you have installed the package for
+ one architecture, use `make distclean' before reconfiguring for another
+ architecture.
+
+ Installation Names
+ ==================
+
+ By default, `make install' will install the package's files in
+ `/usr/local/bin', `/usr/local/man', etc. You can specify an
+ installation prefix other than `/usr/local' by giving `configure' the
+ option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+ architecture-specific files and architecture-independent files. If you
+ give `configure' the option `--exec-prefix=PATH', the package will use
+ PATH as the prefix for installing programs and libraries.
+ Documentation and other data files will still use the regular prefix.
+
+ If the package supports it, you can cause programs to be installed
+ with an extra prefix or suffix on their names by giving `configure' the
+ option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Optional Features
+ =================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+ `configure', where FEATURE indicates an optional part of the package.
+ They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+ is something like `gnu-as' or `x' (for the X Window System). The
+ `README' should mention any `--enable-' and `--with-' options that the
+ package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+ find the X include and library files automatically, but if it doesn't,
+ you can use the `configure' options `--x-includes=DIR' and
+ `--x-libraries=DIR' to specify their locations.
+
+ Specifying the System Type
+ ==========================
+
+ There may be some features `configure' can not figure out
+ automatically, but needs to determine by the type of host the package
+ will run on. Usually `configure' can figure that out, but if it prints
+ a message saying it can not guess the host type, give it the
+ `--host=TYPE' option. TYPE can either be a short name for the system
+ type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+ See the file `config.sub' for the possible values of each field. If
+ `config.sub' isn't included in this package, then this package doesn't
+ need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+ use the `--target=TYPE' option to select the type of system they will
+ produce code for and the `--build=TYPE' option to select the type of
+ system on which you are compiling the package.
+
+ Sharing Defaults
+ ================
+
+ If you want to set default values for `configure' scripts to share,
+ you can create a site shell script called `config.site' that gives
+ default values for variables like `CC', `cache_file', and `prefix'.
+ `configure' looks for `PREFIX/share/config.site' if it exists, then
+ `PREFIX/etc/config.site' if it exists. Or, you can set the
+ `CONFIG_SITE' environment variable to the location of the site script.
+ A warning: not all `configure' scripts look for a site script.
+
+ Operation Controls
+ ==================
+
+ `configure' recognizes the following options to control how it
+ operates.
+
+ `--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+ `--help'
+ Print a summary of the options to `configure', and exit.
+
+ `--quiet'
+ `--silent'
+ `-q'
+ Do not print messages saying which checks are being made.
+
+ `--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+ `--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+ `configure' also accepts some other, not widely useful, options.

+ GNU AFFERO GENERAL PUBLIC LICENSE
+ Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU Affero General Public License is a free, copyleft license for
+ software and other kinds of works, specifically designed to ensure
+ cooperation with the community in the case of network server software.
+
+ The licenses for most software and other practical works are designed
+ to take away your freedom to share and change the works. By contrast,
+ our General Public Licenses are intended to guarantee your freedom to
+ share and change all versions of a program--to make sure it remains free
+ software for all its users.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ Developers that use our General Public Licenses protect your rights
+ with two steps: (1) assert copyright on the software, and (2) offer
+ you this License which gives you legal permission to copy, distribute
+ and/or modify the software.
+
+ A secondary benefit of defending all users' freedom is that
+ improvements made in alternate versions of the program, if they
+ receive widespread use, become available for other developers to
+ incorporate. Many developers of free software are heartened and
+ encouraged by the resulting cooperation. However, in the case of
+ software used on network servers, this result may fail to come about.
+ The GNU General Public License permits making a modified version and
+ letting the public access it on a server without ever releasing its
+ source code to the public.
+
+ The GNU Affero General Public License is designed specifically to
+ ensure that, in such cases, the modified source code becomes available
+ to the community. It requires the operator of a network server to
+ provide the source code of the modified version running there to the
+ users of that server. Therefore, public use of a modified version, on
+ a publicly accessible server, gives the public access to the source
+ code of the modified version.
+
+ An older license, called the Affero General Public License and
+ published by Affero, was designed to accomplish similar goals. This is
+ a different license, not a version of the Affero GPL, but Affero has
+ released a new version of the Affero GPL which permits relicensing under
+ this license.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU Affero General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+ works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as "you". "Licensees" and
+ "recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of an
+ exact copy. The resulting work is called a "modified version" of the
+ earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+ on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user through
+ a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+ for making modifications to it. "Object code" means any non-source
+ form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ "Major Component", in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+ can regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise remains
+ in force. You may convey covered works to others for the sole purpose
+ of having them make modifications exclusively for you, or provide you
+ with facilities for running those works, provided that you comply with
+ the terms of this License in conveying all material for which you do
+ not control copyright. Those thus making or running the covered works
+ for you must do so exclusively on your behalf, under your direction
+ and control, on terms that prohibit them from making any copies of
+ your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such circumvention
+ is effected by exercising rights under this License with respect to
+ the covered work, and you disclaim any intention to limit operation or
+ modification of the work as a means of enforcing, against the work's
+ users, your or third parties' legal rights to forbid circumvention of
+ technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ "aggregate" if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this License,
+ in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+ tangible personal property which is normally used for personal, family,
+ or household purposes, or (2) anything designed or sold for incorporation
+ into a dwelling. In determining whether a product is a consumer product,
+ doubtful cases shall be resolved in favor of coverage. For a particular
+ product received by a particular user, "normally used" refers to a
+ typical or common use of that class of product, regardless of the status
+ of the particular user or of the way in which the particular user
+ actually uses, or expects or is expected to use, the product. A product
+ is a consumer product regardless of whether the product has substantial
+ commercial, industrial or non-consumer uses, unless such uses represent
+ the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+ procedures, authorization keys, or other information required to install
+ and execute modified versions of a covered work in that User Product from
+ a modified version of its Corresponding Source. The information must
+ suffice to ensure that the continued functioning of the modified object
+ code is in no case prevented or interfered with solely because
+ modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or updates
+ for a work that has been modified or installed by the recipient, or for
+ the User Product in which it has been modified or installed. Access to a
+ network may be denied when the modification itself materially and
+ adversely affects the operation of the network or violates the rules and
+ protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders of
+ that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+ restrictions" within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the copyright
+ holder fails to notify you of the violation by some reasonable means
+ prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, "control" includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To "grant" such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. "Knowingly relying" means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that are
+ specifically granted under this License. You may not convey a covered
+ work if you are a party to an arrangement with a third party that is
+ in the business of distributing software, under which you make payment
+ to the third party based on the extent of your activity of conveying
+ the work, and under which the third party grants, to any of the
+ parties who would receive the covered work from you, a discriminatory
+ patent license (a) in connection with copies of the covered work
+ conveyed by you (or copies made from those copies), or (b) primarily
+ for and in connection with specific products or compilations that
+ contain the covered work, unless you entered into that arrangement,
+ or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey a
+ covered work so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you may
+ not convey it at all. For example, if you agree to terms that obligate you
+ to collect a royalty for further conveying from those to whom you convey
+ the Program, the only way you could satisfy both those terms and this
+ License would be to refrain entirely from conveying the Program.
+
+ 13. Remote Network Interaction; Use with the GNU General Public License.
+
+ Notwithstanding any other provision of this License, if you modify the
+ Program, your modified version must prominently offer all users
+ interacting with it remotely through a computer network (if your version
+ supports such interaction) an opportunity to receive the Corresponding
+ Source of your version by providing access to the Corresponding Source
+ from a network server at no charge, through some standard or customary
+ means of facilitating copying of software. This Corresponding Source
+ shall include the Corresponding Source for any work covered by version 3
+ of the GNU General Public License that is incorporated pursuant to the
+ following paragraph.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU General Public License into a single
+ combined work, and to convey the resulting work. The terms of this
+ License will continue to apply to the part which is the covered work,
+ but the work with which it is combined will remain governed by version
+ 3 of the GNU General Public License.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+ the GNU Affero General Public License from time to time. Such new versions
+ will be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies that a certain numbered version of the GNU Affero General
+ Public License "or any later version" applies to it, you have the
+ option of following the terms and conditions either of that numbered
+ version or of any later version published by the Free Software
+ Foundation. If the Program does not specify a version number of the
+ GNU Affero General Public License, you may choose any version ever published
+ by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+ versions of the GNU Affero General Public License can be used, that proxy's
+ public statement of acceptance of a version permanently authorizes you
+ to choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+ OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+ THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+ IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+ THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+ GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+ USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+ DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+ PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+ EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+ SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU Affero General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU Affero General Public License for more details.
+
+ You should have received a copy of the GNU Affero General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If your software can interact with users remotely through a computer
+ network, you should also make sure that it provides a way for users to
+ get its source. For example, if your program is a web application, its
+ interface could display a "Source" link that leads users to an archive
+ of the code. There are many ways you could offer source, and different
+ solutions will be better for different programs; see section 13 for the
+ specific requirements.
+
+ You should also get your employer (if you work as a programmer) or school,
+ if any, to sign a "copyright disclaimer" for the program, if necessary.
+ For more information on this, and how to apply and follow the GNU AGPL, see
+ <http://www.gnu.org/licenses/>.

+
+ GNU GENERAL PUBLIC LICENSE
+ Version 1, February 1989
+
+ Copyright (C) 1989 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The license agreements of most software companies try to keep users
+ at the mercy of those companies. By contrast, our General Public
+ License is intended to guarantee your freedom to share and change free
+ software--to make sure the software is free for all its users. The
+ General Public License applies to the Free Software Foundation's
+ software and to any other program whose authors commit to using it.
+ You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Specifically, the General Public License is designed to make
+ sure that you have the freedom to give away or sell copies of free
+ software, that you receive source code or can get it if you want it,
+ that you can change the software or use pieces of it in new free
+ programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of a such a program, whether
+ gratis or for a fee, you must give the recipients all the rights that
+ you have. You must make sure that they, too, receive or can get the
+ source code. And you must tell them their rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+ (2) offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+ that everyone understands that there is no warranty for this free
+ software. If the software is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the original
+ authors' reputations.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+ \f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any program or other work which
+ contains a notice placed by the copyright holder saying it may be
+ distributed under the terms of this General Public License. The
+ "Program", below, refers to any such program or work, and a "work based
+ on the Program" means either the Program or any work containing the
+ Program or a portion of it, either verbatim or with modifications. Each
+ licensee is addressed as "you".
+
+ 1. You may copy and distribute verbatim copies of the Program's source
+ code as you receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice and
+ disclaimer of warranty; keep intact all the notices that refer to this
+ General Public License and to the absence of any warranty; and give any
+ other recipients of the Program a copy of this General Public License
+ along with the Program. You may charge a fee for the physical act of
+ transferring a copy.
+
+ 2. You may modify your copy or copies of the Program or any portion of
+ it, and copy and distribute such modifications under the terms of Paragraph
+ 1 above, provided that you also do the following:
+
+ a) cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change; and
+
+ b) cause the whole of any work that you distribute or publish, that
+ in whole or in part contains the Program or any part thereof, either
+ with or without modifications, to be licensed at no charge to all
+ third parties under the terms of this General Public License (except
+ that you may choose to grant warranty protection to some or all
+ third parties, at your option).
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the simplest and most usual way, to print or display an
+ announcement including an appropriate copyright notice and a notice
+ that there is no warranty (or else, saying that you provide a
+ warranty) and that users may redistribute the program under these
+ conditions, and telling the user how to view a copy of this General
+ Public License.
+
+ d) You may charge a fee for the physical act of transferring a
+ copy, and you may at your option offer warranty protection in
+ exchange for a fee.
+
+ Mere aggregation of another independent work with the Program (or its
+ derivative) on a volume of a storage or distribution medium does not bring
+ the other work under the scope of these terms.
+ \f
+ 3. You may copy and distribute the Program (or a portion or derivative of
+ it, under Paragraph 2) in object code or executable form under the terms of
+ Paragraphs 1 and 2 above provided that you also do one of the following:
+
+ a) accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ b) accompany it with a written offer, valid for at least three
+ years, to give any third party free (except for a nominal charge
+ for the cost of distribution) a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ c) accompany it with the information you received as to where the
+ corresponding source code may be obtained. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form alone.)
+
+ Source code for a work means the preferred form of the work for making
+ modifications to it. For an executable file, complete source code means
+ all the source code for all modules it contains; but, as a special
+ exception, it need not include source code for modules which are standard
+ libraries that accompany the operating system on which the executable
+ file runs, or for standard header files or definitions files that
+ accompany that operating system.
+
+ 4. You may not copy, modify, sublicense, distribute or transfer the
+ Program except as expressly provided under this General Public License.
+ Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+ the Program is void, and will automatically terminate your rights to use
+ the Program under this License. However, parties who have received
+ copies, or rights to use copies, from you under this General Public
+ License will not have their licenses terminated so long as such parties
+ remain in full compliance.
+
+ 5. By copying, distributing or modifying the Program (or any work based
+ on the Program) you indicate your acceptance of this license to do so,
+ and all its terms and conditions.
+
+ 6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the original
+ licensor to copy, distribute or modify the Program subject to these
+ terms and conditions. You may not impose any further restrictions on the
+ recipients' exercise of the rights granted herein.
+ \f
+ 7. The Free Software Foundation may publish revised and/or new versions
+ of the General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of the license which applies to it and "any
+ later version", you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Program does not specify a version number of
+ the license, you may choose any version ever published by the Free Software
+ Foundation.
+
+ 8. If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the author
+ to ask for permission. For software which is copyrighted by the Free
+ Software Foundation, write to the Free Software Foundation; we sometimes
+ make exceptions for this. Our decision will be guided by the two goals
+ of preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+ OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+ TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+ REPAIR OR CORRECTION.

+ 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to humanity, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these
+ terms.
+
+ To do so, attach the following notices to the program. It is safest to
+ attach them to the start of each source file to most effectively convey
+ the exclusion of warranty; and each file should have at least the
+ "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by

+ any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
+
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program is interactive, make it output a short notice like this
+ when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19xx name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+ The hypothetical commands `show w' and `show c' should show the
+ appropriate parts of the General Public License. Of course, the
+ commands you use may be called something other than `show w' and `show
+ c'; they could even be mouse-clicks or menu items--whatever suits your
+ program.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a "copyright disclaimer" for the program, if
+ necessary. Here a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ program `Gnomovision' (a program to direct compilers to make passes

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ License is intended to guarantee your freedom to share and change free
+ software--to make sure the software is free for all its users. This
+ General Public License applies to most of the Free Software
+ Foundation's software and to any other program whose authors commit to
+ using it. (Some other Free Software Foundation software is covered by
+ the GNU Lesser General Public License instead.) You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must give the recipients all the rights that
+ you have. You must make sure that they, too, receive or can get the
+ source code. And you must show them these terms so they know their
+ rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+ (2) offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+ that everyone understands that there is no warranty for this free
+ software. If the software is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the original
+ authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that redistributors of a free
+ program will individually obtain patent licenses, in effect making the
+ program proprietary. To prevent this, we have made it clear that any
+ patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+ a notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The "Program", below,
+ refers to any such program or work, and a "work based on the Program"
+ means either the Program or any derivative work under copyright law:
+ that is to say, a work containing the Program or a portion of it,
+ either verbatim or with modifications and/or translated into another
+ language. (Hereinafter, translation is included without limitation in
+ the term "modification".) Each licensee is addressed as "you".
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the
+ Program (independent of having been made by running the Program).
+ Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any warranty;
+ and give any other recipients of the Program a copy of this License
+ along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Program, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source
+ code means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to
+ control compilation and installation of the executable. However, as a
+ special exception, the source code distributed need not include
+ anything that is normally distributed (in either source or binary
+ form) with the major components (compiler, kernel, and so on) of the
+ operating system on which the executable runs, unless that component
+ itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Program or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Program (or any work based on the
+ Program), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject to
+ these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Program at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Program by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Program under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+ of the General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of this License which applies to it and "any
+ later version", you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Program does not specify a version number of
+ this License, you may choose any version ever published by the Free Software
+ Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the author
+ to ask for permission. For software which is copyrighted by the Free
+ Software Foundation, write to the Free Software Foundation; we sometimes
+ make exceptions for this. Our decision will be guided by the two goals
+ of preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+ OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+ TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+ REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+ OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+ TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+ YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+ PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+ POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest

+ This General Public License does not permit incorporating your program into

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+ software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+ to take away your freedom to share and change the works. By contrast,
+ the GNU General Public License is intended to guarantee your freedom to
+ share and change all versions of a program--to make sure it remains free
+ software for all its users. We, the Free Software Foundation, use the
+ GNU General Public License for most of our software; it applies also to
+ any other work released this way by its authors. You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+ these rights or asking you to surrender the rights. Therefore, you have
+ certain responsibilities if you distribute copies of the software, or if
+ you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must pass on to the recipients the same
+ freedoms that you received. You must make sure that they, too, receive
+ or can get the source code. And you must show them these terms so they
+ know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+ (1) assert copyright on the software, and (2) offer you this License
+ giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+ that there is no warranty for this free software. For both users' and
+ authors' sake, the GPL requires that modified versions be marked as
+ changed, so that their problems will not be attributed erroneously to
+ authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+ modified versions of the software inside them, although the manufacturer
+ can do so. This is fundamentally incompatible with the aim of
+ protecting users' freedom to change the software. The systematic
+ pattern of such abuse occurs in the area of products for individuals to
+ use, which is precisely where it is most unacceptable. Therefore, we
+ have designed this version of the GPL to prohibit the practice for those
+ products. If such problems arise substantially in other domains, we
+ stand ready to extend this provision to those domains in future versions
+ of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+ States should not allow patents to restrict development and use of
+ software on general-purpose computers, but in those that do, we wish to
+ avoid the special danger that patents applied to a free program could
+ make it effectively proprietary. To prevent this, the GPL assures that
+ patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+ works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as "you". "Licensees" and
+ "recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of an
+ exact copy. The resulting work is called a "modified version" of the
+ earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+ on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user through
+ a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+ for making modifications to it. "Object code" means any non-source
+ form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ "Major Component", in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+ can regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise remains
+ in force. You may convey covered works to others for the sole purpose
+ of having them make modifications exclusively for you, or provide you
+ with facilities for running those works, provided that you comply with
+ the terms of this License in conveying all material for which you do
+ not control copyright. Those thus making or running the covered works
+ for you must do so exclusively on your behalf, under your direction
+ and control, on terms that prohibit them from making any copies of
+ your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such circumvention
+ is effected by exercising rights under this License with respect to
+ the covered work, and you disclaim any intention to limit operation or
+ modification of the work as a means of enforcing, against the work's
+ users, your or third parties' legal rights to forbid circumvention of
+ technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ "aggregate" if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this License,
+ in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+ tangible personal property which is normally used for personal, family,
+ or household purposes, or (2) anything designed or sold for incorporation
+ into a dwelling. In determining whether a product is a consumer product,
+ doubtful cases shall be resolved in favor of coverage. For a particular
+ product received by a particular user, "normally used" refers to a
+ typical or common use of that class of product, regardless of the status
+ of the particular user or of the way in which the particular user
+ actually uses, or expects or is expected to use, the product. A product
+ is a consumer product regardless of whether the product has substantial
+ commercial, industrial or non-consumer uses, unless such uses represent
+ the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+ procedures, authorization keys, or other information required to install
+ and execute modified versions of a covered work in that User Product from
+ a modified version of its Corresponding Source. The information must
+ suffice to ensure that the continued functioning of the modified object
+ code is in no case prevented or interfered with solely because
+ modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or updates
+ for a work that has been modified or installed by the recipient, or for
+ the User Product in which it has been modified or installed. Access to a
+ network may be denied when the modification itself materially and
+ adversely affects the operation of the network or violates the rules and
+ protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders of
+ that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+ restrictions" within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the copyright
+ holder fails to notify you of the violation by some reasonable means
+ prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, "control" includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To "grant" such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. "Knowingly relying" means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that are
+ specifically granted under this License. You may not convey a covered
+ work if you are a party to an arrangement with a third party that is
+ in the business of distributing software, under which you make payment
+ to the third party based on the extent of your activity of conveying
+ the work, and under which the third party grants, to any of the
+ parties who would receive the covered work from you, a discriminatory
+ patent license (a) in connection with copies of the covered work
+ conveyed by you (or copies made from those copies), or (b) primarily
+ for and in connection with specific products or compilations that
+ contain the covered work, unless you entered into that arrangement,
+ or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey a
+ covered work so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you may
+ not convey it at all. For example, if you agree to terms that obligate you
+ to collect a royalty for further conveying from those to whom you convey
+ the Program, the only way you could satisfy both those terms and this
+ License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU Affero General Public License into a single
+ combined work, and to convey the resulting work. The terms of this
+ License will continue to apply to the part which is the covered work,
+ but the special requirements of the GNU Affero General Public License,
+ section 13, concerning interaction through a network will apply to the
+ combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+ the GNU General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies that a certain numbered version of the GNU General
+ Public License "or any later version" applies to it, you have the
+ option of following the terms and conditions either of that numbered
+ version or of any later version published by the Free Software
+ Foundation. If the Program does not specify a version number of the
+ GNU General Public License, you may choose any version ever published
+ by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+ versions of the GNU General Public License can be used, that proxy's
+ public statement of acceptance of a version permanently authorizes you
+ to choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+ OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+ THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+ IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+ THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+ GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+ USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+ DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+ PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+ EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+ SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+ notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+ The hypothetical commands `show w' and `show c' should show the appropriate
+ parts of the General Public License. Of course, your program's commands
+ might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+ if any, to sign a "copyright disclaimer" for the program, if necessary.
+ For more information on this, and how to apply and follow the GNU GPL, see
+ <http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+ into proprietary programs. If your program is a subroutine library, you
+ may consider it more useful to permit linking proprietary applications with
+ the library. If this is what you want to do, use the GNU Lesser General
+ Public License instead of this License. But first, please read
+ <http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ [This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ Licenses are intended to guarantee your freedom to share and change
+ free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+ specially designated Free Software Foundation software, and to any
+ other libraries whose authors decide to use it. You can use it for
+ your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if
+ you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+ or for a fee, you must give the recipients all the rights that we gave
+ you. You must make sure that they, too, receive or can get the source
+ code. If you link a program with the library, you must provide
+ complete object files to the recipients so that they can relink them
+ with the library, after making changes to the library and recompiling
+ it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+ the library, and (2) offer you this license which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+ that everyone understands that there is no warranty for this free
+ library. If the library is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original
+ version, so that any problems introduced by others will not reflect on
+ the original authors' reputations.
+ \f
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that companies distributing free
+ software will individually obtain patent licenses, thus in effect
+ transforming the program into proprietary software. To prevent this,
+ we have made it clear that any patent must be licensed for everyone's
+ free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+ GNU General Public License, which was designed for utility programs. This
+ license, the GNU Library General Public License, applies to certain
+ designated libraries. This license is quite different from the ordinary
+ one; be sure to read it in full, and don't assume that anything in it is
+ the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+ they blur the distinction we usually make between modifying or adding to a
+ program and simply using it. Linking a program with a library, without
+ changing the library, is in some sense simply using the library, and is
+ analogous to running a utility program or application program. However, in
+ a textual and legal sense, the linked executable is a combined work, a
+ derivative of the original library, and the ordinary General Public License
+ treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+ Public License for libraries did not effectively promote software
+ sharing, because most developers did not use the libraries. We
+ concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+ users of those programs of all benefit from the free status of the
+ libraries themselves. This Library General Public License is intended to
+ permit developers of non-free programs to use free libraries, while
+ preserving your freedom as a user of such programs to change the free
+ libraries that are incorporated in them. (We have not seen how to achieve
+ this as regards changes in header files, but we have achieved it as regards
+ changes in the actual functions of the Library.) The hope is that this
+ will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow. Pay close attention to the difference between a
+ "work based on the library" and a "work that uses the library". The
+ former contains code derived from the library, while the latter only
+ works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+ General Public License rather than by this special one.
+ \f
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+ contains a notice placed by the copyright holder or other authorized
+ party saying it may be distributed under the terms of this Library
+ General Public License (also called "this License"). Each licensee is
+ addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+ which has been distributed under these terms. A "work based on the
+ Library" means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control compilation
+ and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does
+ and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+ complete source code as you receive it, in any medium, provided that
+ you conspicuously and appropriately publish on each copy an
+ appropriate copyright notice and disclaimer of warranty; keep intact
+ all the notices that refer to this License and to the absence of any
+ warranty; and distribute a copy of this License along with the
+ Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange for a
+ fee.
+ \f
+ 2. You may modify your copy or copies of the Library or any portion
+ of it, thus forming a work based on the Library, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+ \f
+ Once this change is made in a given copy, it is irreversible for
+ that copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+ the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+ derivative of it, under Section 2) in object code or executable form
+ under the terms of Sections 1 and 2 above provided that you accompany
+ it with the complete corresponding machine-readable source code, which
+ must be distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+ from a designated place, then offering equivalent access to copy the
+ source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a "work that uses the Library". Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a "work that uses the
+ library". The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+ structure layouts and accessors, and small macros and small inline
+ functions (ten lines or less in length), then the use of the object
+ file is unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+ \f
+ 6. As an exception to the Sections above, you may also compile or
+ link a "work that uses the Library" with the Library to produce a
+ work containing portions of the Library, and distribute that work
+ under terms of your choice, provided that the terms permit
+ modification of the work for the customer's own use and reverse
+ engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+ Library" must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the source code distributed need not include anything that is normally
+ distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+ \f
+ 7. You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+ the Library except as expressly provided under this License. Any
+ attempt otherwise to copy, modify, sublicense, link with, or
+ distribute the Library is void, and will automatically terminate your
+ rights under this License. However, parties who have received copies,
+ or rights, from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+ \f
+ 11. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply,
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License may add
+ an explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+ versions of the Library General Public License from time to time.
+ Such new versions will be similar in spirit to the present version,
+ but may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and
+ "any later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a
+ license version number, you may choose any version ever published by
+ the Free Software Foundation.
+ \f
+ 14. If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free
+ Software Foundation; we sometimes make exceptions for this. Our
+ decision will be guided by the two goals of preserving the free status
+ of all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+ EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+ OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+ KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+ IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+ LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+ THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+ AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+ FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+ CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+ LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+ RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+ FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+ SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+ DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+ \f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+ possible use to the public, we recommend making it free software that
+ everyone can redistribute and change. You can do so by permitting
+ redistribution under these terms (or, alternatively, under the terms of the
+ ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+
+ You should have received a copy of the GNU Library General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a "copyright disclaimer" for the library, if
+ necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ [This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ Licenses are intended to guarantee your freedom to share and change
+ free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+ specially designated software packages--typically libraries--of the
+ Free Software Foundation and other authors who decide to use it. You
+ can use it too, but we suggest you first think carefully about whether
+ this license or the ordinary General Public License is the better
+ strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+ not price. Our General Public Licenses are designed to make sure that
+ you have the freedom to distribute copies of free software (and charge
+ for this service if you wish); that you receive source code or can get
+ it if you want it; that you can change the software and use pieces of
+ it in new free programs; and that you are informed that you can do
+ these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ distributors to deny you these rights or to ask you to surrender these
+ rights. These restrictions translate to certain responsibilities for
+ you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+ or for a fee, you must give the recipients all the rights that we gave
+ you. You must make sure that they, too, receive or can get the source
+ code. If you link other code with the library, you must provide
+ complete object files to the recipients, so that they can relink them
+ with the library after making changes to the library and recompiling
+ it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+ library, and (2) we offer you this license, which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+ there is no warranty for the free library. Also, if the library is
+ modified by someone else and passed on, the recipients should know
+ that what they have is not the original version, so that the original
+ author's reputation will not be affected by problems that might be
+ introduced by others.
+ \f
+ Finally, software patents pose a constant threat to the existence of
+ any free program. We wish to make sure that a company cannot
+ effectively restrict the users of a free program by obtaining a
+ restrictive license from a patent holder. Therefore, we insist that
+ any patent license obtained for a version of the library must be
+ consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ ordinary GNU General Public License. This license, the GNU Lesser
+ General Public License, applies to certain designated libraries, and
+ is quite different from the ordinary General Public License. We use
+ this license for certain libraries in order to permit linking those
+ libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+ a shared library, the combination of the two is legally speaking a
+ combined work, a derivative of the original library. The ordinary
+ General Public License therefore permits such linking only if the
+ entire combination fits its criteria of freedom. The Lesser General
+ Public License permits more lax criteria for linking other code with
+ the library.
+
+ We call this license the "Lesser" General Public License because it
+ does Less to protect the user's freedom than the ordinary General
+ Public License. It also provides other free software developers Less
+ of an advantage over competing non-free programs. These disadvantages
+ are the reason we use the ordinary General Public License for many
+ libraries. However, the Lesser license provides advantages in certain
+ special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+ encourage the widest possible use of a certain library, so that it becomes
+ a de-facto standard. To achieve this, non-free programs must be
+ allowed to use the library. A more frequent case is that a free
+ library does the same job as widely used non-free libraries. In this
+ case, there is little to gain by limiting the free library to free
+ software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+ programs enables a greater number of people to use a large body of
+ free software. For example, permission to use the GNU C Library in
+ non-free programs enables many more people to use the whole GNU
+ operating system, as well as its variant, the GNU/Linux operating
+ system.
+
+ Although the Lesser General Public License is Less protective of the
+ users' freedom, it does ensure that the user of a program that is
+ linked with the Library has the freedom and the wherewithal to run
+ that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow. Pay close attention to the difference between a
+ "work based on the library" and a "work that uses the library". The
+ former contains code derived from the library, whereas the latter must
+ be combined with the library in order to run.
+ \f
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+ program which contains a notice placed by the copyright holder or
+ other authorized party saying it may be distributed under the terms of
+ this Lesser General Public License (also called "this License").
+ Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+ which has been distributed under these terms. A "work based on the
+ Library" means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control compilation
+ and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does
+ and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+ complete source code as you receive it, in any medium, provided that
+ you conspicuously and appropriately publish on each copy an
+ appropriate copyright notice and disclaimer of warranty; keep intact
+ all the notices that refer to this License and to the absence of any
+ warranty; and distribute a copy of this License along with the
+ Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange for a
+ fee.
+ \f
+ 2. You may modify your copy or copies of the Library or any portion
+ of it, thus forming a work based on the Library, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+ \f
+ Once this change is made in a given copy, it is irreversible for
+ that copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+ the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+ derivative of it, under Section 2) in object code or executable form
+ under the terms of Sections 1 and 2 above provided that you accompany
+ it with the complete corresponding machine-readable source code, which
+ must be distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+ from a designated place, then offering equivalent access to copy the
+ source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a "work that uses the Library". Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a "work that uses the
+ library". The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+ structure layouts and accessors, and small macros and small inline
+ functions (ten lines or less in length), then the use of the object
+ file is unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+ \f
+ 6. As an exception to the Sections above, you may also combine or
+ link a "work that uses the Library" with the Library to produce a
+ work containing portions of the Library, and distribute that work
+ under terms of your choice, provided that the terms permit
+ modification of the work for the customer's own use and reverse
+ engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+ Library" must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the materials to be distributed need not include anything that is
+ normally distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+ \f
+ 7. You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+ the Library except as expressly provided under this License. Any
+ attempt otherwise to copy, modify, sublicense, link with, or
+ distribute the Library is void, and will automatically terminate your
+ rights under this License. However, parties who have received copies,
+ or rights, from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties with
+ this License.
+ \f
+ 11. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply,
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License may add
+ an explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+ versions of the Lesser General Public License from time to time.
+ Such new versions will be similar in spirit to the present version,
+ but may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and
+ "any later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a
+ license version number, you may choose any version ever published by
+ the Free Software Foundation.
+ \f
+ 14. If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free
+ Software Foundation; we sometimes make exceptions for this. Our
+ decision will be guided by the two goals of preserving the free status
+ of all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+ EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+ OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+ KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+ IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+ LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+ THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+ AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+ FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+ CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+ LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+ RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+ FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+ SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+ DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+ \f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+ possible use to the public, we recommend making it free software that
+ everyone can redistribute and change. You can do so by permitting
+ redistribution under these terms (or, alternatively, under the terms of the
+ ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a "copyright disclaimer" for the library, if
+ necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+ the terms and conditions of version 3 of the GNU General Public
+ License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+ General Public License, and the "GNU GPL" refers to version 3 of the GNU
+ General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+ other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+ by the Library, but which is not otherwise based on the Library.
+ Defining a subclass of a class defined by the Library is deemed a mode
+ of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+ Application with the Library. The particular version of the Library
+ with which the Combined Work was made is also called the "Linked
+ Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+ Corresponding Source for the Combined Work, excluding any source code
+ for portions of the Combined Work that, considered in isolation, are
+ based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+ object code and/or source code for the Application, including any data
+ and utility programs needed for reproducing the Combined Work from the
+ Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+ without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+ facility refers to a function or data to be supplied by an Application
+ that uses the facility (other than as an argument passed when the
+ facility is invoked), then you may convey a copy of the modified
+ version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+ a header file that is part of the Library. You may convey such object
+ code under terms of your choice, provided that, if the incorporated
+ material is not limited to numerical parameters, data structure
+ layouts and accessors, or small macros, inline functions and templates
+ (ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+ taken together, effectively do not restrict modification of the
+ portions of the Library contained in the Combined Work and reverse
+ engineering for debugging such modifications, if you also do each of
+ the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+ Library side by side in a single library together with other library
+ facilities that are not Applications and are not covered by this
+ License, and convey such a combined library under terms of your
+ choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+ of the GNU Lesser General Public License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Library as you received it specifies that a certain numbered version
+ of the GNU Lesser General Public License "or any later version"
+ applies to it, you have the option of following the terms and
+ conditions either of that published version or of any later version
+ published by the Free Software Foundation. If the Library as you
+ received it does not specify a version number of the GNU Lesser
+ General Public License, you may choose any version of the GNU Lesser
+ General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+ whether future versions of the GNU Lesser General Public License shall
+ apply, that proxy's public statement of acceptance of any version is
+ permanent authorization for you to choose that version for the
+ Library.

+
+ \renewcommand{\abstractname}{Preamble}
+ \begin{abstract}
+ The GNU Affero General Public License is a free, copyleft license
+ for software and other kinds of works, specifically designed to ensure
+ cooperation with the community in the case of network server software.
+
+ The licenses for most software and other practical works are
+ designed to take away your freedom to share and change the works. By
+ contrast, our General Public Licenses are intended to guarantee your
+ freedom to share and change all versions of a program--to make sure it
+ remains free software for all its users.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ Developers that use our General Public Licenses protect your rights
+ with two steps: (1) assert copyright on the software, and (2) offer
+ you this License which gives you legal permission to copy, distribute
+ and/or modify the software.
+
+ A secondary benefit of defending all users' freedom is that
+ improvements made in alternate versions of the program, if they
+ receive widespread use, become available for other developers to
+ incorporate. Many developers of free software are heartened and
+ encouraged by the resulting cooperation. However, in the case of
+ software used on network servers, this result may fail to come about.
+ The GNU General Public License permits making a modified version and
+ letting the public access it on a server without ever releasing its
+ source code to the public.
+
+ The GNU Affero General Public License is designed specifically to
+ ensure that, in such cases, the modified source code becomes available
+ to the community. It requires the operator of a network server to
+ provide the source code of the modified version running there to the
+ users of that server. Therefore, public use of a modified version, on
+ a publicly accessible server, gives the public access to the source
+ code of the modified version.
+
+ An older license, called the Affero General Public License and
+ published by Affero, was designed to accomplish similar goals. This is
+ a different license, not a version of the Affero GPL, but Affero has
+ released a new version of the Affero GPL which permits relicensing under
+ this license.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+ \end{abstract}
+
+ \begin{center}
+ {\Large \sc Terms and Conditions}
+ \end{center}
+
+
+ \begin{enumerate}
+
+ \addtocounter{enumi}{-1}
+
+ \item Definitions.
+
+ ``This License'' refers to version 3 of the GNU Affero General Public License.
+
+ ``Copyright'' also means copyright-like laws that apply to other kinds of
+ works, such as semiconductor masks.
+
+ ``The Program'' refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as ``you''. ``Licensees'' and
+ ``recipients'' may be individuals or organizations.
+
+ To ``modify'' a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of an
+ exact copy. The resulting work is called a ``modified version'' of the
+ earlier work or a work ``based on'' the earlier work.
+
+ A ``covered work'' means either the unmodified Program or a work based
+ on the Program.
+
+ To ``propagate'' a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To ``convey'' a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user through
+ a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays ``Appropriate Legal Notices''
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ \item Source Code.
+
+ The ``source code'' for a work means the preferred form of the work
+ for making modifications to it. ``Object code'' means any non-source
+ form of a work.
+
+ A ``Standard Interface'' means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The ``System Libraries'' of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ ``Major Component'', in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The ``Corresponding Source'' for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+ can regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ \item Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise remains
+ in force. You may convey covered works to others for the sole purpose
+ of having them make modifications exclusively for you, or provide you
+ with facilities for running those works, provided that you comply with
+ the terms of this License in conveying all material for which you do
+ not control copyright. Those thus making or running the covered works
+ for you must do so exclusively on your behalf, under your direction
+ and control, on terms that prohibit them from making any copies of
+ your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ \item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such circumvention
+ is effected by exercising rights under this License with respect to
+ the covered work, and you disclaim any intention to limit operation or
+ modification of the work as a means of enforcing, against the work's
+ users, your or third parties' legal rights to forbid circumvention of
+ technological measures.
+
+ \item Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ \item Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these conditions:
+ \begin{enumerate}
+ \item The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ \item The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ ``keep intact all notices''.
+
+ \item You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ \item If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+ \end{enumerate}
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ ``aggregate'' if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ \item Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this License,
+ in one of these ways:
+ \begin{enumerate}
+ \item Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ \item Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ \item Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ \item Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ \item Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+ \end{enumerate}
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A ``User Product'' is either (1) a ``consumer product'', which means any
+ tangible personal property which is normally used for personal, family,
+ or household purposes, or (2) anything designed or sold for incorporation
+ into a dwelling. In determining whether a product is a consumer product,
+ doubtful cases shall be resolved in favor of coverage. For a particular
+ product received by a particular user, ``normally used'' refers to a
+ typical or common use of that class of product, regardless of the status
+ of the particular user or of the way in which the particular user
+ actually uses, or expects or is expected to use, the product. A product
+ is a consumer product regardless of whether the product has substantial
+ commercial, industrial or non-consumer uses, unless such uses represent
+ the only significant mode of use of the product.
+
+ ``Installation Information'' for a User Product means any methods,
+ procedures, authorization keys, or other information required to install
+ and execute modified versions of a covered work in that User Product from
+ a modified version of its Corresponding Source. The information must
+ suffice to ensure that the continued functioning of the modified object
+ code is in no case prevented or interfered with solely because
+ modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or updates
+ for a work that has been modified or installed by the recipient, or for
+ the User Product in which it has been modified or installed. Access to a
+ network may be denied when the modification itself materially and
+ adversely affects the operation of the network or violates the rules and
+ protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ \item Additional Terms.
+
+ ``Additional permissions'' are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders of
+ that material) supplement the terms of this License with terms:
+ \begin{enumerate}
+ \item Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ \item Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ \item Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ \item Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ \item Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ \item Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+ \end{enumerate}
+
+ All other non-permissive additional terms are considered ``further
+ restrictions'' within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ \item Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the copyright
+ holder fails to notify you of the violation by some reasonable means
+ prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ \item Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ \item Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An ``entity transaction'' is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ \item Patents.
+
+ A ``contributor'' is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's ``contributor version''.
+
+ A contributor's ``essential patent claims'' are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, ``control'' includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a ``patent license'' is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To ``grant'' such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. ``Knowingly relying'' means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is ``discriminatory'' if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that are
+ specifically granted under this License. You may not convey a covered
+ work if you are a party to an arrangement with a third party that is
+ in the business of distributing software, under which you make payment
+ to the third party based on the extent of your activity of conveying
+ the work, and under which the third party grants, to any of the
+ parties who would receive the covered work from you, a discriminatory
+ patent license (a) in connection with copies of the covered work
+ conveyed by you (or copies made from those copies), or (b) primarily
+ for and in connection with specific products or compilations that
+ contain the covered work, unless you entered into that arrangement,
+ or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ \item No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey a
+ covered work so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you may
+ not convey it at all. For example, if you agree to terms that obligate you
+ to collect a royalty for further conveying from those to whom you convey
+ the Program, the only way you could satisfy both those terms and this
+ License would be to refrain entirely from conveying the Program.
+
+ \item Remote Network Interaction; Use with the GNU General Public License.
+
+ Notwithstanding any other provision of this License, if you modify the
+ Program, your modified version must prominently offer all users interacting
+ with it remotely through a computer network (if your version supports such
+ interaction) an opportunity to receive the Corresponding Source of your
+ version by providing access to the Corresponding Source from a network
+ server at no charge, through some standard or customary means of
+ facilitating copying of software. This Corresponding Source shall include
+ the Corresponding Source for any work covered by version 3 of the GNU
+ General Public License that is incorporated pursuant to the following
+ paragraph.
+
+ Notwithstanding any other provision of this License, you have permission to
+ link or combine any covered work with a work licensed under version 3 of
+ the GNU General Public License into a single combined work, and to convey
+ the resulting work. The terms of this License will continue to apply to
+ the part which is the covered work, but the work with which it is combined
+ will remain governed by version 3 of the GNU General Public License.
+
+ \item Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+ the GNU Affero General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies that a certain numbered version of the GNU Affero General
+ Public License ``or any later version'' applies to it, you have the
+ option of following the terms and conditions either of that numbered
+ version or of any later version published by the Free Software
+ Foundation. If the Program does not specify a version number of the
+ GNU Affero General Public License, you may choose any version ever published
+ by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+ versions of the GNU Affero General Public License can be used, that proxy's
+ public statement of acceptance of a version permanently authorizes you
+ to choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ \item Disclaimer of Warranty.
+
+ \begin{sloppypar}
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+ COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
+ WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+ INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
+ RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+ SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+ \end{sloppypar}
+
+ \item Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+ AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+ DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+ DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+ (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+ INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
+ OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
+ HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+ DAMAGES.
+
+ \item Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.

+ \bigskip
+ How to Apply These Terms to Your New Programs
+ \end{center}
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the ``copyright'' line and a pointer to where the full notice is found.
+
+ {\footnotesize
+ \begin{verbatim}
+ <one line to give the program's name and a brief idea of what it does.>
+
+ Copyright (C) <textyear> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU Affero General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU Affero General Public License for more details.
+
+ You should have received a copy of the GNU Affero General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+ \end{verbatim}
+ }
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If your software can interact with users remotely through a computer
+ network, you should also make sure that it provides a way for users to
+ get its source. For example, if your program is a web application, its
+ interface could display a ``Source'' link that leads users to an archive
+ of the code. There are many ways you could offer source, and different
+ solutions will be better for different programs; see section 13 for the
+ specific requirements.
+
+ You should also get your employer (if you work as a programmer) or
+ school, if any, to sign a ``copyright disclaimer'' for the program, if
+ necessary. For more information on this, and how to apply and follow
+ the GNU AGPL, see \texttt{http://www.gnu.org/licenses/}.

+
+ @display
+ Copyright @copyright{} 2007 Free Software Foundation, Inc. @url{http://fsf.org/}
+
+ Everyone is permitted to copy and distribute verbatim copies of this
+ license document, but changing it is not allowed.

+
+ @heading Preamble
+
+ The GNU Affero General Public License is a free, copyleft license
+ for software and other kinds of works, specifically designed to ensure
+ cooperation with the community in the case of network server software.
+
+ The licenses for most software and other practical works are
+ designed to take away your freedom to share and change the works. By
+ contrast, our General Public Licenses are intended to guarantee your
+ freedom to share and change all versions of a program--to make sure it
+ remains free software for all its users.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ Developers that use our General Public Licenses protect your rights
+ with two steps: (1) assert copyright on the software, and (2) offer
+ you this License which gives you legal permission to copy, distribute
+ and/or modify the software.
+
+ A secondary benefit of defending all users' freedom is that
+ improvements made in alternate versions of the program, if they
+ receive widespread use, become available for other developers to
+ incorporate. Many developers of free software are heartened and
+ encouraged by the resulting cooperation. However, in the case of
+ software used on network servers, this result may fail to come about.
+ The GNU General Public License permits making a modified version and
+ letting the public access it on a server without ever releasing its
+ source code to the public.
+
+ The GNU Affero General Public License is designed specifically to
+ ensure that, in such cases, the modified source code becomes available
+ to the community. It requires the operator of a network server to
+ provide the source code of the modified version running there to the
+ users of that server. Therefore, public use of a modified version, on
+ a publicly accessible server, gives the public access to the source
+ code of the modified version.
+
+ An older license, called the Affero General Public License and
+ published by Affero, was designed to accomplish similar goals. This is
+ a different license, not a version of the Affero GPL, but Affero has
+ released a new version of the Affero GPL which permits relicensing under
+ this license.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ @heading TERMS AND CONDITIONS
+
+ @enumerate 0
+ @item Definitions.
+
+ ``This License'' refers to version 3 of the GNU Affero General Public License.
+
+ ``Copyright'' also means copyright-like laws that apply to other kinds
+ of works, such as semiconductor masks.
+
+ ``The Program'' refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as ``you''. ``Licensees'' and
+ ``recipients'' may be individuals or organizations.
+
+ To ``modify'' a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of
+ an exact copy. The resulting work is called a ``modified version'' of
+ the earlier work or a work ``based on'' the earlier work.
+
+ A ``covered work'' means either the unmodified Program or a work based
+ on the Program.
+
+ To ``propagate'' a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To ``convey'' a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user
+ through a computer network, with no transfer of a copy, is not
+ conveying.
+
+ An interactive user interface displays ``Appropriate Legal Notices'' to
+ the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ @item Source Code.
+
+ The ``source code'' for a work means the preferred form of the work for
+ making modifications to it. ``Object code'' means any non-source form
+ of a work.
+
+ A ``Standard Interface'' means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The ``System Libraries'' of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ ``Major Component'', in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The ``Corresponding Source'' for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users can
+ regenerate automatically from other parts of the Corresponding Source.
+
+ The Corresponding Source for a work in source code form is that same
+ work.
+
+ @item Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not convey,
+ without conditions so long as your license otherwise remains in force.
+ You may convey covered works to others for the sole purpose of having
+ them make modifications exclusively for you, or provide you with
+ facilities for running those works, provided that you comply with the
+ terms of this License in conveying all material for which you do not
+ control copyright. Those thus making or running the covered works for
+ you must do so exclusively on your behalf, under your direction and
+ control, on terms that prohibit them from making any copies of your
+ copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under the
+ conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ @item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such
+ circumvention is effected by exercising rights under this License with
+ respect to the covered work, and you disclaim any intention to limit
+ operation or modification of the work as a means of enforcing, against
+ the work's users, your or third parties' legal rights to forbid
+ circumvention of technological measures.
+
+ @item Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ @item Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these
+ conditions:
+
+ @enumerate a
+ @item
+ The work must carry prominent notices stating that you modified it,
+ and giving a relevant date.
+
+ @item
+ The work must carry prominent notices stating that it is released
+ under this License and any conditions added under section 7. This
+ requirement modifies the requirement in section 4 to ``keep intact all
+ notices''.
+
+ @item
+ You must license the entire work, as a whole, under this License to
+ anyone who comes into possession of a copy. This License will
+ therefore apply, along with any applicable section 7 additional terms,
+ to the whole of the work, and all its parts, regardless of how they
+ are packaged. This License gives no permission to license the work in
+ any other way, but it does not invalidate such permission if you have
+ separately received it.
+
+ @item
+ If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your work
+ need not make them do so.
+ @end enumerate
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ ``aggregate'' if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ @item Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms of
+ sections 4 and 5, provided that you also convey the machine-readable
+ Corresponding Source under the terms of this License, in one of these
+ ways:
+
+ @enumerate a
+ @item
+ Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium customarily
+ used for software interchange.
+
+ @item
+ Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a written
+ offer, valid for at least three years and valid for as long as you
+ offer spare parts or customer support for that product model, to give
+ anyone who possesses the object code either (1) a copy of the
+ Corresponding Source for all the software in the product that is
+ covered by this License, on a durable physical medium customarily used
+ for software interchange, for a price no more than your reasonable
+ cost of physically performing this conveying of source, or (2) access
+ to copy the Corresponding Source from a network server at no charge.
+
+ @item
+ Convey individual copies of the object code with a copy of the written
+ offer to provide the Corresponding Source. This alternative is
+ allowed only occasionally and noncommercially, and only if you
+ received the object code with such an offer, in accord with subsection
+ 6b.
+
+ @item
+ Convey the object code by offering access from a designated place
+ (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to copy
+ the object code is a network server, the Corresponding Source may be
+ on a different server (operated by you or a third party) that supports
+ equivalent copying facilities, provided you maintain clear directions
+ next to the object code saying where to find the Corresponding Source.
+ Regardless of what server hosts the Corresponding Source, you remain
+ obligated to ensure that it is available for as long as needed to
+ satisfy these requirements.
+
+ @item
+ Convey the object code using peer-to-peer transmission, provided you
+ inform other peers where the object code and Corresponding Source of
+ the work are being offered to the general public at no charge under
+ subsection 6d.
+
+ @end enumerate
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A ``User Product'' is either (1) a ``consumer product'', which means any
+ tangible personal property which is normally used for personal,
+ family, or household purposes, or (2) anything designed or sold for
+ incorporation into a dwelling. In determining whether a product is a
+ consumer product, doubtful cases shall be resolved in favor of
+ coverage. For a particular product received by a particular user,
+ ``normally used'' refers to a typical or common use of that class of
+ product, regardless of the status of the particular user or of the way
+ in which the particular user actually uses, or expects or is expected
+ to use, the product. A product is a consumer product regardless of
+ whether the product has substantial commercial, industrial or
+ non-consumer uses, unless such uses represent the only significant
+ mode of use of the product.
+
+ ``Installation Information'' for a User Product means any methods,
+ procedures, authorization keys, or other information required to
+ install and execute modified versions of a covered work in that User
+ Product from a modified version of its Corresponding Source. The
+ information must suffice to ensure that the continued functioning of
+ the modified object code is in no case prevented or interfered with
+ solely because modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or
+ updates for a work that has been modified or installed by the
+ recipient, or for the User Product in which it has been modified or
+ installed. Access to a network may be denied when the modification
+ itself materially and adversely affects the operation of the network
+ or violates the rules and protocols for communication across the
+ network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ @item Additional Terms.
+
+ ``Additional permissions'' are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders
+ of that material) supplement the terms of this License with terms:
+
+ @enumerate a
+ @item
+ Disclaiming warranty or limiting liability differently from the terms
+ of sections 15 and 16 of this License; or
+
+ @item
+ Requiring preservation of specified reasonable legal notices or author
+ attributions in that material or in the Appropriate Legal Notices
+ displayed by works containing it; or
+
+ @item
+ Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ @item
+ Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ @item
+ Declining to grant rights under trademark law for use of some trade
+ names, trademarks, or service marks; or
+
+ @item
+ Requiring indemnification of licensors and authors of that material by
+ anyone who conveys the material (or modified versions of it) with
+ contractual assumptions of liability to the recipient, for any
+ liability that these contractual assumptions directly impose on those
+ licensors and authors.
+ @end enumerate
+
+ All other non-permissive additional terms are considered ``further
+ restrictions'' within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions; the
+ above requirements apply either way.
+
+ @item Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your license
+ from a particular copyright holder is reinstated (a) provisionally,
+ unless and until the copyright holder explicitly and finally
+ terminates your license, and (b) permanently, if the copyright holder
+ fails to notify you of the violation by some reasonable means prior to
+ 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ @item Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or run
+ a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ @item Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An ``entity transaction'' is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ @item Patents.
+
+ A ``contributor'' is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's ``contributor version''.
+
+ A contributor's ``essential patent claims'' are all patent claims owned
+ or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, ``control'' includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a ``patent license'' is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To ``grant'' such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. ``Knowingly relying'' means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is ``discriminatory'' if it does not include within the
+ scope of its coverage, prohibits the exercise of, or is conditioned on
+ the non-exercise of one or more of the rights that are specifically
+ granted under this License. You may not convey a covered work if you
+ are a party to an arrangement with a third party that is in the
+ business of distributing software, under which you make payment to the
+ third party based on the extent of your activity of conveying the
+ work, and under which the third party grants, to any of the parties
+ who would receive the covered work from you, a discriminatory patent
+ license (a) in connection with copies of the covered work conveyed by
+ you (or copies made from those copies), or (b) primarily for and in
+ connection with specific products or compilations that contain the
+ covered work, unless you entered into that arrangement, or that patent
+ license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ @item No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey
+ a covered work so as to satisfy simultaneously your obligations under
+ this License and any other pertinent obligations, then as a
+ consequence you may not convey it at all. For example, if you agree
+ to terms that obligate you to collect a royalty for further conveying
+ from those to whom you convey the Program, the only way you could
+ satisfy both those terms and this License would be to refrain entirely
+ from conveying the Program.
+
+ @item Remote Network Interaction; Use with the GNU General Public License.
+
+ Notwithstanding any other provision of this License, if you modify the
+ Program, your modified version must prominently offer all users interacting
+ with it remotely through a computer network (if your version supports such
+ interaction) an opportunity to receive the Corresponding Source of your
+ version by providing access to the Corresponding Source from a network
+ server at no charge, through some standard or customary means of
+ facilitating copying of software. This Corresponding Source shall include
+ the Corresponding Source for any work covered by version 3 of the GNU
+ General Public License that is incorporated pursuant to the following
+ paragraph.
+
+ Notwithstanding any other provision of this License, you have permission to
+ link or combine any covered work with a work licensed under version 3 of
+ the GNU General Public License into a single combined work, and to convey
+ the resulting work. The terms of this License will continue to apply to
+ the part which is the covered work, but the work with which it is combined
+ will remain governed by version 3 of the GNU General Public License.
+
+ @item Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions
+ of the GNU Affero General Public License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies that a certain numbered version of the GNU Affero General Public
+ License ``or any later version'' applies to it, you have the option of
+ following the terms and conditions either of that numbered version or
+ of any later version published by the Free Software Foundation. If
+ the Program does not specify a version number of the GNU Affero General
+ Public License, you may choose any version ever published by the Free
+ Software Foundation.
+
+ If the Program specifies that a proxy can decide which future versions
+ of the GNU Affero General Public License can be used, that proxy's public
+ statement of acceptance of a version permanently authorizes you to
+ choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ @item Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+ WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+ LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+ A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+ PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+ DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+ CORRECTION.
+
+ @item Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+ CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+ NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+ LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+ TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+ PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+ @item Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.
+
+ @end enumerate
+
+ @heading END OF TERMS AND CONDITIONS
+
+ @heading How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these
+ terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the ``copyright'' line and a pointer to where the full notice is found.
+
+ @smallexample
+ @var{one line to give the program's name and a brief idea of what it does.}
+ Copyright (C) @var{year} @var{name of author}
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU Affero General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or (at
+ your option) any later version.
+
+ This program is distributed in the hope that it will be useful, but
+ WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Affero General Public License for more details.
+
+ You should have received a copy of the GNU Affero General Public License
+ along with this program. If not, see @url{http://www.gnu.org/licenses/}.
+ @end smallexample
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If your software can interact with users remotely through a computer
+ network, you should also make sure that it provides a way for users to
+ get its source. For example, if your program is a web application, its
+ interface could display a ``Source'' link that leads users to an archive
+ of the code. There are many ways you could offer source, and different
+ solutions will be better for different programs; see section 13 for the
+ specific requirements.
+
+ You should also get your employer (if you work as a programmer) or school,
+ if any, to sign a ``copyright disclaimer'' for the program, if necessary.
+ For more information on this, and how to apply and follow the GNU AGPL, see
+ @url{http://www.gnu.org/licenses/}.

+ {\bf\large Preamble}
+ \end{center}
+
+
+ The licenses for most software are designed to take away your freedom to
+ share and change it. By contrast, the GNU General Public License is
+ intended to guarantee your freedom to share and change free software---to
+ make sure the software is free for all its users. This General Public
+ License applies to most of the Free Software Foundation's software and to
+ any other program whose authors commit to using it. (Some other Free
+ Software Foundation software is covered by the GNU Library General Public
+ License instead.) You can apply it to your programs, too.
+
+ When we speak of free software, we are referring to freedom, not price.
+ Our General Public Licenses are designed to make sure that you have the
+ freedom to distribute copies of free software (and charge for this service
+ if you wish), that you receive source code or can get it if you want it,
+ that you can change the software or use pieces of it in new free programs;
+ and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid anyone to
+ deny you these rights or to ask you to surrender the rights. These
+ restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether gratis or
+ for a fee, you must give the recipients all the rights that you have. You
+ must make sure that they, too, receive or can get the source code. And
+ you must show them these terms so they know their rights.
+
+ We protect your rights with two steps: (1) copyright the software, and (2)
+ offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain that
+ everyone understands that there is no warranty for this free software. If
+ the software is modified by someone else and passed on, we want its
+ recipients to know that what they have is not the original, so that any
+ problems introduced by others will not reflect on the original authors'
+ reputations.
+
+ Finally, any free program is threatened constantly by software patents.
+ We wish to avoid the danger that redistributors of a free program will
+ individually obtain patent licenses, in effect making the program
+ proprietary. To prevent this, we have made it clear that any patent must
+ be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ \begin{center}
+ {\Large \sc Terms and Conditions For Copying, Distribution and
+ Modification}
+ \end{center}
+
+
+ \begin{enumerate}
+
+ \addtocounter{enumi}{-1}
+
+ \item
+
+ This License applies to any program or other work which contains a notice
+ placed by the copyright holder saying it may be distributed under the
+ terms of this General Public License. The ``Program'', below, refers to
+ any such program or work, and a ``work based on the Program'' means either
+ the Program or any derivative work under copyright law: that is to say, a
+ work containing the Program or a portion of it, either verbatim or with
+ modifications and/or translated into another language. (Hereinafter,
+ translation is included without limitation in the term ``modification''.)
+ Each licensee is addressed as ``you''.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the
+ Program (independent of having been made by running the Program).
+ Whether that is true depends on what the Program does.
+
+ \item You may copy and distribute verbatim copies of the Program's source
+ code as you receive it, in any medium, provided that you conspicuously
+ and appropriately publish on each copy an appropriate copyright notice
+ and disclaimer of warranty; keep intact all the notices that refer to
+ this License and to the absence of any warranty; and give any other
+ recipients of the Program a copy of this License along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and you
+ may at your option offer warranty protection in exchange for a fee.
+
+ \item
+
+ You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ \begin{enumerate}
+
+ \item
+
+ You must cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change.
+
+ \item
+
+ You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ \item
+ If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+ \end{enumerate}
+
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Program, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ \item
+ You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you also do one of the following:
+
+ \begin{enumerate}
+
+ \item
+
+ Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ \item
+
+ Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ \item
+
+ Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+ \end{enumerate}
+
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source
+ code means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to
+ control compilation and installation of the executable. However, as a
+ special exception, the source code distributed need not include
+ anything that is normally distributed (in either source or binary
+ form) with the major components (compiler, kernel, and so on) of the
+ operating system on which the executable runs, unless that component
+ itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ \item
+ You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ \item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Program or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Program (or any work based on the
+ Program), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Program or works based on it.
+
+ \item
+ Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject to
+ these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ \item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Program at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Program by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ \item
+ If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Program under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ \item
+ The Free Software Foundation may publish revised and/or new versions
+ of the General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of this License which applies to it and ``any
+ later version'', you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Program does not specify a version number of
+ this License, you may choose any version ever published by the Free Software
+ Foundation.
+
+ \item
+ If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the author
+ to ask for permission. For software which is copyrighted by the Free
+ Software Foundation, write to the Free Software Foundation; we sometimes
+ make exceptions for this. Our decision will be guided by the two goals
+ of preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.

+ \section*{Appendix: How to Apply These Terms to Your New Programs}
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these
+ terms.
+
+ To do so, attach the following notices to the program. It is safest to
+ attach them to the start of each source file to most effectively convey
+ the exclusion of warranty; and each file should have at least the
+ ``copyright'' line and a pointer to where the full notice is found.
+
+ \begin{quote}
+ one line to give the program's name and a brief idea of what it does. \\
+ Copyright (C) yyyy name of author \\
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
+ \end{quote}
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program is interactive, make it output a short notice like this
+ when it starts in an interactive mode:
+
+ \begin{quote}
+ Gnomovision version 69, Copyright (C) yyyy name of author \\
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. \\
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+ \end{quote}
+
+
+ The hypothetical commands {\tt show w} and {\tt show c} should show the
+ appropriate parts of the General Public License. Of course, the commands
+ you use may be called something other than {\tt show w} and {\tt show c};
+ they could even be mouse-clicks or menu items---whatever suits your
+ program.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a ``copyright disclaimer'' for the program, if
+ necessary. Here is a sample; alter the names:
+
+ \begin{quote}
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program \\
+ `Gnomovision' (which makes passes at compilers) written by James Hacker. \\
+
+ signature of Ty Coon, 1 April 1989 \\
+ Ty Coon, President of Vice
+ \end{quote}
+
+
+ This General Public License does not permit incorporating your program
+ into proprietary programs. If your program is a subroutine library, you
+ may consider it more useful to permit linking proprietary applications
+ with the library. If this is what you want to do, use the GNU Library
+ General Public License instead of this License.

+
+ @heading Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ License is intended to guarantee your freedom to share and change free
+ software---to make sure the software is free for all its users. This
+ General Public License applies to most of the Free Software
+ Foundation's software and to any other program whose authors commit to
+ using it. (Some other Free Software Foundation software is covered by
+ the GNU Lesser General Public License instead.) You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must give the recipients all the rights that
+ you have. You must make sure that they, too, receive or can get the
+ source code. And you must show them these terms so they know their
+ rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+ (2) offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+ that everyone understands that there is no warranty for this free
+ software. If the software is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the original
+ authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that redistributors of a free
+ program will individually obtain patent licenses, in effect making the
+ program proprietary. To prevent this, we have made it clear that any
+ patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ @heading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ @enumerate 0
+ @item
+ This License applies to any program or other work which contains
+ a notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The ``Program'', below,
+ refers to any such program or work, and a ``work based on the Program''
+ means either the Program or any derivative work under copyright law:
+ that is to say, a work containing the Program or a portion of it,
+ either verbatim or with modifications and/or translated into another
+ language. (Hereinafter, translation is included without limitation in
+ the term ``modification''.) Each licensee is addressed as ``you''.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the
+ Program (independent of having been made by running the Program).
+ Whether that is true depends on what the Program does.
+
+ @item
+ You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any warranty;
+ and give any other recipients of the Program a copy of this License
+ along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+ @item
+ You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ @enumerate a
+ @item
+ You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ @item
+ You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ @item
+ If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+ @end enumerate
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based

+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or

+
+ @enumerate a
+ @item
+ Accompany it with the complete corresponding machine-readable

+ school, if any, to sign a ``copyright disclaimer'' for the program, if
+ necessary. Here is a sample; alter the names:
+
+ @smallexample

+
+ This General Public License does not permit incorporating your program into
+ proprietary programs. If your program is a subroutine library, you may
+ consider it more useful to permit linking proprietary applications with the
+ library. If this is what you want to do, use the GNU Lesser General
+ Public License instead of this License.

+
+ \renewcommand{\abstractname}{Preamble}
+ \begin{abstract}
+ The GNU General Public License is a free, copyleft license for
+ software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+ to take away your freedom to share and change the works. By contrast,
+ the GNU General Public License is intended to guarantee your freedom to
+ share and change all versions of a program--to make sure it remains free
+ software for all its users. We, the Free Software Foundation, use the
+ GNU General Public License for most of our software; it applies also to
+ any other work released this way by its authors. You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+ these rights or asking you to surrender the rights. Therefore, you have
+ certain responsibilities if you distribute copies of the software, or if
+ you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must pass on to the recipients the same
+ freedoms that you received. You must make sure that they, too, receive
+ or can get the source code. And you must show them these terms so they
+ know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+ (1) assert copyright on the software, and (2) offer you this License
+ giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+ that there is no warranty for this free software. For both users' and
+ authors' sake, the GPL requires that modified versions be marked as
+ changed, so that their problems will not be attributed erroneously to
+ authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+ modified versions of the software inside them, although the manufacturer
+ can do so. This is fundamentally incompatible with the aim of
+ protecting users' freedom to change the software. The systematic
+ pattern of such abuse occurs in the area of products for individuals to
+ use, which is precisely where it is most unacceptable. Therefore, we
+ have designed this version of the GPL to prohibit the practice for those
+ products. If such problems arise substantially in other domains, we
+ stand ready to extend this provision to those domains in future versions
+ of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+ States should not allow patents to restrict development and use of
+ software on general-purpose computers, but in those that do, we wish to
+ avoid the special danger that patents applied to a free program could
+ make it effectively proprietary. To prevent this, the GPL assures that
+ patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+ \end{abstract}
+
+ \begin{center}
+ {\Large \sc Terms and Conditions}
+ \end{center}
+
+
+ \begin{enumerate}
+
+ \addtocounter{enumi}{-1}
+
+ \item Definitions.
+
+ ``This License'' refers to version 3 of the GNU General Public License.
+
+ ``Copyright'' also means copyright-like laws that apply to other kinds of
+ works, such as semiconductor masks.
+
+ ``The Program'' refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as ``you''. ``Licensees'' and
+ ``recipients'' may be individuals or organizations.
+
+ To ``modify'' a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of an
+ exact copy. The resulting work is called a ``modified version'' of the
+ earlier work or a work ``based on'' the earlier work.
+
+ A ``covered work'' means either the unmodified Program or a work based
+ on the Program.
+
+ To ``propagate'' a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To ``convey'' a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user through
+ a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays ``Appropriate Legal Notices''
+ to the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ \item Source Code.
+
+ The ``source code'' for a work means the preferred form of the work
+ for making modifications to it. ``Object code'' means any non-source
+ form of a work.
+
+ A ``Standard Interface'' means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The ``System Libraries'' of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ ``Major Component'', in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The ``Corresponding Source'' for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+ can regenerate automatically from other parts of the Corresponding
+ Source.
+
+ The Corresponding Source for a work in source code form is that
+ same work.
+
+ \item Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+ convey, without conditions so long as your license otherwise remains
+ in force. You may convey covered works to others for the sole purpose
+ of having them make modifications exclusively for you, or provide you
+ with facilities for running those works, provided that you comply with
+ the terms of this License in conveying all material for which you do
+ not control copyright. Those thus making or running the covered works
+ for you must do so exclusively on your behalf, under your direction
+ and control, on terms that prohibit them from making any copies of
+ your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+ the conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ \item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such circumvention
+ is effected by exercising rights under this License with respect to
+ the covered work, and you disclaim any intention to limit operation or
+ modification of the work as a means of enforcing, against the work's
+ users, your or third parties' legal rights to forbid circumvention of
+ technological measures.
+
+ \item Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ \item Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these conditions:
+ \begin{enumerate}
+ \item The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ \item The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ ``keep intact all notices''.
+
+ \item You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ \item If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+ \end{enumerate}
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ ``aggregate'' if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ \item Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+ of sections 4 and 5, provided that you also convey the
+ machine-readable Corresponding Source under the terms of this License,
+ in one of these ways:
+ \begin{enumerate}
+ \item Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ \item Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ \item Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ \item Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ \item Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+ \end{enumerate}
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A ``User Product'' is either (1) a ``consumer product'', which means any
+ tangible personal property which is normally used for personal, family,
+ or household purposes, or (2) anything designed or sold for incorporation
+ into a dwelling. In determining whether a product is a consumer product,
+ doubtful cases shall be resolved in favor of coverage. For a particular
+ product received by a particular user, ``normally used'' refers to a
+ typical or common use of that class of product, regardless of the status
+ of the particular user or of the way in which the particular user
+ actually uses, or expects or is expected to use, the product. A product
+ is a consumer product regardless of whether the product has substantial
+ commercial, industrial or non-consumer uses, unless such uses represent
+ the only significant mode of use of the product.
+
+ ``Installation Information'' for a User Product means any methods,
+ procedures, authorization keys, or other information required to install
+ and execute modified versions of a covered work in that User Product from
+ a modified version of its Corresponding Source. The information must
+ suffice to ensure that the continued functioning of the modified object
+ code is in no case prevented or interfered with solely because
+ modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or updates
+ for a work that has been modified or installed by the recipient, or for
+ the User Product in which it has been modified or installed. Access to a
+ network may be denied when the modification itself materially and
+ adversely affects the operation of the network or violates the rules and
+ protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ \item Additional Terms.
+
+ ``Additional permissions'' are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders of
+ that material) supplement the terms of this License with terms:
+ \begin{enumerate}
+ \item Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ \item Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ \item Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ \item Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ \item Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ \item Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+ \end{enumerate}
+
+ All other non-permissive additional terms are considered ``further
+ restrictions'' within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions;
+ the above requirements apply either way.
+
+ \item Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the copyright
+ holder fails to notify you of the violation by some reasonable means
+ prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ \item Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+ run a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ \item Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An ``entity transaction'' is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ \item Patents.
+
+ A ``contributor'' is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's ``contributor version''.
+
+ A contributor's ``essential patent claims'' are all patent claims
+ owned or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, ``control'' includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a ``patent license'' is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To ``grant'' such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. ``Knowingly relying'' means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is ``discriminatory'' if it does not include within
+ the scope of its coverage, prohibits the exercise of, or is
+ conditioned on the non-exercise of one or more of the rights that are
+ specifically granted under this License. You may not convey a covered
+ work if you are a party to an arrangement with a third party that is
+ in the business of distributing software, under which you make payment
+ to the third party based on the extent of your activity of conveying
+ the work, and under which the third party grants, to any of the
+ parties who would receive the covered work from you, a discriminatory
+ patent license (a) in connection with copies of the covered work
+ conveyed by you (or copies made from those copies), or (b) primarily
+ for and in connection with specific products or compilations that
+ contain the covered work, unless you entered into that arrangement,
+ or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ \item No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey a
+ covered work so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you may
+ not convey it at all. For example, if you agree to terms that obligate you
+ to collect a royalty for further conveying from those to whom you convey
+ the Program, the only way you could satisfy both those terms and this
+ License would be to refrain entirely from conveying the Program.
+
+ \item Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU Affero General Public License into a single
+ combined work, and to convey the resulting work. The terms of this
+ License will continue to apply to the part which is the covered work,
+ but the special requirements of the GNU Affero General Public License,
+ section 13, concerning interaction through a network will apply to the
+ combination as such.
+
+ \item Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+ the GNU General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Program specifies that a certain numbered version of the GNU General
+ Public License ``or any later version'' applies to it, you have the
+ option of following the terms and conditions either of that numbered
+ version or of any later version published by the Free Software
+ Foundation. If the Program does not specify a version number of the
+ GNU General Public License, you may choose any version ever published
+ by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+ versions of the GNU General Public License can be used, that proxy's
+ public statement of acceptance of a version permanently authorizes you
+ to choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ \item Disclaimer of Warranty.
+
+ \begin{sloppypar}
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+ COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
+ WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+ INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
+ RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
+ SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+ \end{sloppypar}
+
+ \item Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
+ AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+ DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+ DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+ (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+ INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
+ OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
+ HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+ DAMAGES.
+
+ \item Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.

+ How to Apply These Terms to Your New Programs
+ \end{center}
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the ``copyright'' line and a pointer to where the full notice is found.
+
+ {\footnotesize
+ \begin{verbatim}
+ <one line to give the program's name and a brief idea of what it does.>
+
+ Copyright (C) <textyear> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+ \end{verbatim}
+ }
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+ notice like this when it starts in an interactive mode:
+
+ {\footnotesize
+ \begin{verbatim}
+ <program> Copyright (C) <year> <name of author>
+
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+ \end{verbatim}
+ }
+
+ The hypothetical commands {\tt show w} and {\tt show c} should show
+ the appropriate
+ parts of the General Public License. Of course, your program's commands
+ might be different; for a GUI interface, you would use an ``about box''.
+
+ You should also get your employer (if you work as a programmer) or
+ school, if any, to sign a ``copyright disclaimer'' for the program, if
+ necessary. For more information on this, and how to apply and follow
+ the GNU GPL, see \texttt{http://www.gnu.org/licenses/}.
+
+ The GNU General Public License does not permit incorporating your
+ program into proprietary programs. If your program is a subroutine
+ library, you may consider it more useful to permit linking proprietary
+ applications with the library. If this is what you want to do, use
+ the GNU Lesser General Public License instead of this License. But
+ first, please read \texttt{http://www.gnu.org/philosophy/why-not-lgpl.html}.

+

+ @c hence no sectioning command or @node.
+
+ @display
+ Copyright @copyright{} 2007 Free Software Foundation, Inc. @url{http://fsf.org/}
+
+ Everyone is permitted to copy and distribute verbatim copies of this
+ license document, but changing it is not allowed.
+ @end display
+
+ @heading Preamble
+
+ The GNU General Public License is a free, copyleft license for
+ software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+ to take away your freedom to share and change the works. By contrast,
+ the GNU General Public License is intended to guarantee your freedom
+ to share and change all versions of a program---to make sure it remains
+ free software for all its users. We, the Free Software Foundation,
+ use the GNU General Public License for most of our software; it
+ applies also to any other work released this way by its authors. You
+ can apply it to your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ them if you wish), that you receive source code or can get it if you
+ want it, that you can change the software or use pieces of it in new
+ free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+ these rights or asking you to surrender the rights. Therefore, you
+ have certain responsibilities if you distribute copies of the
+ software, or if you modify it: responsibilities to respect the freedom
+ of others.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must pass on to the recipients the same
+ freedoms that you received. You must make sure that they, too,
+ receive or can get the source code. And you must show them these
+ terms so they know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+ (1) assert copyright on the software, and (2) offer you this License
+ giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+ that there is no warranty for this free software. For both users' and
+ authors' sake, the GPL requires that modified versions be marked as
+ changed, so that their problems will not be attributed erroneously to
+ authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+ modified versions of the software inside them, although the
+ manufacturer can do so. This is fundamentally incompatible with the
+ aim of protecting users' freedom to change the software. The
+ systematic pattern of such abuse occurs in the area of products for
+ individuals to use, which is precisely where it is most unacceptable.
+ Therefore, we have designed this version of the GPL to prohibit the
+ practice for those products. If such problems arise substantially in
+ other domains, we stand ready to extend this provision to those
+ domains in future versions of the GPL, as needed to protect the
+ freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+ States should not allow patents to restrict development and use of
+ software on general-purpose computers, but in those that do, we wish
+ to avoid the special danger that patents applied to a free program
+ could make it effectively proprietary. To prevent this, the GPL
+ assures that patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ @heading TERMS AND CONDITIONS
+
+ @enumerate 0
+ @item Definitions.
+
+ ``This License'' refers to version 3 of the GNU General Public License.
+
+ ``Copyright'' also means copyright-like laws that apply to other kinds
+ of works, such as semiconductor masks.
+
+ ``The Program'' refers to any copyrightable work licensed under this
+ License. Each licensee is addressed as ``you''. ``Licensees'' and
+ ``recipients'' may be individuals or organizations.
+
+ To ``modify'' a work means to copy from or adapt all or part of the work
+ in a fashion requiring copyright permission, other than the making of
+ an exact copy. The resulting work is called a ``modified version'' of
+ the earlier work or a work ``based on'' the earlier work.
+
+ A ``covered work'' means either the unmodified Program or a work based
+ on the Program.
+
+ To ``propagate'' a work means to do anything with it that, without
+ permission, would make you directly or secondarily liable for
+ infringement under applicable copyright law, except executing it on a
+ computer or modifying a private copy. Propagation includes copying,
+ distribution (with or without modification), making available to the
+ public, and in some countries other activities as well.
+
+ To ``convey'' a work means any kind of propagation that enables other
+ parties to make or receive copies. Mere interaction with a user
+ through a computer network, with no transfer of a copy, is not
+ conveying.
+
+ An interactive user interface displays ``Appropriate Legal Notices'' to
+ the extent that it includes a convenient and prominently visible
+ feature that (1) displays an appropriate copyright notice, and (2)
+ tells the user that there is no warranty for the work (except to the
+ extent that warranties are provided), that licensees may convey the
+ work under this License, and how to view a copy of this License. If
+ the interface presents a list of user commands or options, such as a
+ menu, a prominent item in the list meets this criterion.
+
+ @item Source Code.
+
+ The ``source code'' for a work means the preferred form of the work for
+ making modifications to it. ``Object code'' means any non-source form
+ of a work.
+
+ A ``Standard Interface'' means an interface that either is an official
+ standard defined by a recognized standards body, or, in the case of
+ interfaces specified for a particular programming language, one that
+ is widely used among developers working in that language.
+
+ The ``System Libraries'' of an executable work include anything, other
+ than the work as a whole, that (a) is included in the normal form of
+ packaging a Major Component, but which is not part of that Major
+ Component, and (b) serves only to enable use of the work with that
+ Major Component, or to implement a Standard Interface for which an
+ implementation is available to the public in source code form. A
+ ``Major Component'', in this context, means a major essential component
+ (kernel, window system, and so on) of the specific operating system
+ (if any) on which the executable work runs, or a compiler used to
+ produce the work, or an object code interpreter used to run it.
+
+ The ``Corresponding Source'' for a work in object code form means all
+ the source code needed to generate, install, and (for an executable
+ work) run the object code and to modify the work, including scripts to
+ control those activities. However, it does not include the work's
+ System Libraries, or general-purpose tools or generally available free
+ programs which are used unmodified in performing those activities but
+ which are not part of the work. For example, Corresponding Source
+ includes interface definition files associated with source files for
+ the work, and the source code for shared libraries and dynamically
+ linked subprograms that the work is specifically designed to require,
+ such as by intimate data communication or control flow between those
+ subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users can
+ regenerate automatically from other parts of the Corresponding Source.
+
+ The Corresponding Source for a work in source code form is that same
+ work.
+
+ @item Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+ copyright on the Program, and are irrevocable provided the stated
+ conditions are met. This License explicitly affirms your unlimited
+ permission to run the unmodified Program. The output from running a
+ covered work is covered by this License only if the output, given its
+ content, constitutes a covered work. This License acknowledges your
+ rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not convey,
+ without conditions so long as your license otherwise remains in force.
+ You may convey covered works to others for the sole purpose of having
+ them make modifications exclusively for you, or provide you with
+ facilities for running those works, provided that you comply with the
+ terms of this License in conveying all material for which you do not
+ control copyright. Those thus making or running the covered works for
+ you must do so exclusively on your behalf, under your direction and
+ control, on terms that prohibit them from making any copies of your
+ copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under the
+ conditions stated below. Sublicensing is not allowed; section 10
+ makes it unnecessary.
+
+ @item Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+ measure under any applicable law fulfilling obligations under article
+ 11 of the WIPO copyright treaty adopted on 20 December 1996, or
+ similar laws prohibiting or restricting circumvention of such
+ measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+ circumvention of technological measures to the extent such
+ circumvention is effected by exercising rights under this License with
+ respect to the covered work, and you disclaim any intention to limit
+ operation or modification of the work as a means of enforcing, against
+ the work's users, your or third parties' legal rights to forbid
+ circumvention of technological measures.
+
+ @item Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+ receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice;
+ keep intact all notices stating that this License and any
+ non-permissive terms added in accord with section 7 apply to the code;
+ keep intact all notices of the absence of any warranty; and give all
+ recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+ and you may offer support or warranty protection for a fee.
+
+ @item Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+ produce it from the Program, in the form of source code under the
+ terms of section 4, provided that you also meet all of these
+ conditions:
+
+ @enumerate a
+ @item
+ The work must carry prominent notices stating that you modified it,
+ and giving a relevant date.
+
+ @item
+ The work must carry prominent notices stating that it is released
+ under this License and any conditions added under section 7. This
+ requirement modifies the requirement in section 4 to ``keep intact all
+ notices''.
+
+ @item
+ You must license the entire work, as a whole, under this License to
+ anyone who comes into possession of a copy. This License will
+ therefore apply, along with any applicable section 7 additional terms,
+ to the whole of the work, and all its parts, regardless of how they
+ are packaged. This License gives no permission to license the work in
+ any other way, but it does not invalidate such permission if you have
+ separately received it.
+
+ @item
+ If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your work
+ need not make them do so.
+ @end enumerate
+
+ A compilation of a covered work with other separate and independent
+ works, which are not by their nature extensions of the covered work,
+ and which are not combined with it such as to form a larger program,
+ in or on a volume of a storage or distribution medium, is called an
+ ``aggregate'' if the compilation and its resulting copyright are not
+ used to limit the access or legal rights of the compilation's users
+ beyond what the individual works permit. Inclusion of a covered work
+ in an aggregate does not cause this License to apply to the other
+ parts of the aggregate.
+
+ @item Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms of
+ sections 4 and 5, provided that you also convey the machine-readable
+ Corresponding Source under the terms of this License, in one of these
+ ways:
+
+ @enumerate a
+ @item
+ Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium customarily
+ used for software interchange.
+
+ @item
+ Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a written
+ offer, valid for at least three years and valid for as long as you
+ offer spare parts or customer support for that product model, to give
+ anyone who possesses the object code either (1) a copy of the
+ Corresponding Source for all the software in the product that is
+ covered by this License, on a durable physical medium customarily used
+ for software interchange, for a price no more than your reasonable
+ cost of physically performing this conveying of source, or (2) access
+ to copy the Corresponding Source from a network server at no charge.
+
+ @item
+ Convey individual copies of the object code with a copy of the written
+ offer to provide the Corresponding Source. This alternative is
+ allowed only occasionally and noncommercially, and only if you
+ received the object code with such an offer, in accord with subsection
+ 6b.
+
+ @item
+ Convey the object code by offering access from a designated place
+ (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to copy
+ the object code is a network server, the Corresponding Source may be
+ on a different server (operated by you or a third party) that supports
+ equivalent copying facilities, provided you maintain clear directions
+ next to the object code saying where to find the Corresponding Source.
+ Regardless of what server hosts the Corresponding Source, you remain
+ obligated to ensure that it is available for as long as needed to
+ satisfy these requirements.
+
+ @item
+ Convey the object code using peer-to-peer transmission, provided you
+ inform other peers where the object code and Corresponding Source of
+ the work are being offered to the general public at no charge under
+ subsection 6d.
+
+ @end enumerate
+
+ A separable portion of the object code, whose source code is excluded
+ from the Corresponding Source as a System Library, need not be
+ included in conveying the object code work.
+
+ A ``User Product'' is either (1) a ``consumer product'', which means any
+ tangible personal property which is normally used for personal,
+ family, or household purposes, or (2) anything designed or sold for
+ incorporation into a dwelling. In determining whether a product is a
+ consumer product, doubtful cases shall be resolved in favor of
+ coverage. For a particular product received by a particular user,
+ ``normally used'' refers to a typical or common use of that class of
+ product, regardless of the status of the particular user or of the way
+ in which the particular user actually uses, or expects or is expected
+ to use, the product. A product is a consumer product regardless of
+ whether the product has substantial commercial, industrial or
+ non-consumer uses, unless such uses represent the only significant
+ mode of use of the product.
+
+ ``Installation Information'' for a User Product means any methods,
+ procedures, authorization keys, or other information required to
+ install and execute modified versions of a covered work in that User
+ Product from a modified version of its Corresponding Source. The
+ information must suffice to ensure that the continued functioning of
+ the modified object code is in no case prevented or interfered with
+ solely because modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+ specifically for use in, a User Product, and the conveying occurs as
+ part of a transaction in which the right of possession and use of the
+ User Product is transferred to the recipient in perpetuity or for a
+ fixed term (regardless of how the transaction is characterized), the
+ Corresponding Source conveyed under this section must be accompanied
+ by the Installation Information. But this requirement does not apply
+ if neither you nor any third party retains the ability to install
+ modified object code on the User Product (for example, the work has
+ been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+ requirement to continue to provide support service, warranty, or
+ updates for a work that has been modified or installed by the
+ recipient, or for the User Product in which it has been modified or
+ installed. Access to a network may be denied when the modification
+ itself materially and adversely affects the operation of the network
+ or violates the rules and protocols for communication across the
+ network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+ in accord with this section must be in a format that is publicly
+ documented (and with an implementation available to the public in
+ source code form), and must require no special password or key for
+ unpacking, reading or copying.
+
+ @item Additional Terms.
+
+ ``Additional permissions'' are terms that supplement the terms of this
+ License by making exceptions from one or more of its conditions.
+ Additional permissions that are applicable to the entire Program shall
+ be treated as though they were included in this License, to the extent
+ that they are valid under applicable law. If additional permissions
+ apply only to part of the Program, that part may be used separately
+ under those permissions, but the entire Program remains governed by
+ this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+ remove any additional permissions from that copy, or from any part of
+ it. (Additional permissions may be written to require their own
+ removal in certain cases when you modify the work.) You may place
+ additional permissions on material, added by you to a covered work,
+ for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+ add to a covered work, you may (if authorized by the copyright holders
+ of that material) supplement the terms of this License with terms:
+
+ @enumerate a
+ @item
+ Disclaiming warranty or limiting liability differently from the terms
+ of sections 15 and 16 of this License; or
+
+ @item
+ Requiring preservation of specified reasonable legal notices or author
+ attributions in that material or in the Appropriate Legal Notices
+ displayed by works containing it; or
+
+ @item
+ Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ @item
+ Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ @item
+ Declining to grant rights under trademark law for use of some trade
+ names, trademarks, or service marks; or
+
+ @item
+ Requiring indemnification of licensors and authors of that material by
+ anyone who conveys the material (or modified versions of it) with
+ contractual assumptions of liability to the recipient, for any
+ liability that these contractual assumptions directly impose on those
+ licensors and authors.
+ @end enumerate
+
+ All other non-permissive additional terms are considered ``further
+ restrictions'' within the meaning of section 10. If the Program as you
+ received it, or any part of it, contains a notice stating that it is
+ governed by this License along with a term that is a further
+ restriction, you may remove that term. If a license document contains
+ a further restriction but permits relicensing or conveying under this
+ License, you may add to a covered work material governed by the terms
+ of that license document, provided that the further restriction does
+ not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+ must place, in the relevant source files, a statement of the
+ additional terms that apply to those files, or a notice indicating
+ where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+ form of a separately written license, or stated as exceptions; the
+ above requirements apply either way.
+
+ @item Termination.
+
+ You may not propagate or modify a covered work except as expressly
+ provided under this License. Any attempt otherwise to propagate or
+ modify it is void, and will automatically terminate your rights under
+ this License (including any patent licenses granted under the third
+ paragraph of section 11).
+
+ However, if you cease all violation of this License, then your license
+ from a particular copyright holder is reinstated (a) provisionally,
+ unless and until the copyright holder explicitly and finally
+ terminates your license, and (b) permanently, if the copyright holder
+ fails to notify you of the violation by some reasonable means prior to
+ 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from that
+ copyright holder, and you cure the violation prior to 30 days after
+ your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+ licenses of parties who have received copies or rights from you under
+ this License. If your rights have been terminated and not permanently
+ reinstated, you do not qualify to receive new licenses for the same
+ material under section 10.
+
+ @item Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or run
+ a copy of the Program. Ancillary propagation of a covered work
+ occurring solely as a consequence of using peer-to-peer transmission
+ to receive a copy likewise does not require acceptance. However,
+ nothing other than this License grants you permission to propagate or
+ modify any covered work. These actions infringe copyright if you do
+ not accept this License. Therefore, by modifying or propagating a
+ covered work, you indicate your acceptance of this License to do so.
+
+ @item Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+ receives a license from the original licensors, to run, modify and
+ propagate that work, subject to this License. You are not responsible
+ for enforcing compliance by third parties with this License.
+
+ An ``entity transaction'' is a transaction transferring control of an
+ organization, or substantially all assets of one, or subdividing an
+ organization, or merging organizations. If propagation of a covered
+ work results from an entity transaction, each party to that
+ transaction who receives a copy of the work also receives whatever
+ licenses to the work the party's predecessor in interest had or could
+ give under the previous paragraph, plus a right to possession of the
+ Corresponding Source of the work from the predecessor in interest, if
+ the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+ rights granted or affirmed under this License. For example, you may
+ not impose a license fee, royalty, or other charge for exercise of
+ rights granted under this License, and you may not initiate litigation
+ (including a cross-claim or counterclaim in a lawsuit) alleging that
+ any patent claim is infringed by making, using, selling, offering for
+ sale, or importing the Program or any portion of it.
+
+ @item Patents.
+
+ A ``contributor'' is a copyright holder who authorizes use under this
+ License of the Program or a work on which the Program is based. The
+ work thus licensed is called the contributor's ``contributor version''.
+
+ A contributor's ``essential patent claims'' are all patent claims owned
+ or controlled by the contributor, whether already acquired or
+ hereafter acquired, that would be infringed by some manner, permitted
+ by this License, of making, using, or selling its contributor version,
+ but do not include claims that would be infringed only as a
+ consequence of further modification of the contributor version. For
+ purposes of this definition, ``control'' includes the right to grant
+ patent sublicenses in a manner consistent with the requirements of
+ this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+ patent license under the contributor's essential patent claims, to
+ make, use, sell, offer for sale, import and otherwise run, modify and
+ propagate the contents of its contributor version.
+
+ In the following three paragraphs, a ``patent license'' is any express
+ agreement or commitment, however denominated, not to enforce a patent
+ (such as an express permission to practice a patent or covenant not to
+ sue for patent infringement). To ``grant'' such a patent license to a
+ party means to make such an agreement or commitment not to enforce a
+ patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+ and the Corresponding Source of the work is not available for anyone
+ to copy, free of charge and under the terms of this License, through a
+ publicly available network server or other readily accessible means,
+ then you must either (1) cause the Corresponding Source to be so
+ available, or (2) arrange to deprive yourself of the benefit of the
+ patent license for this particular work, or (3) arrange, in a manner
+ consistent with the requirements of this License, to extend the patent
+ license to downstream recipients. ``Knowingly relying'' means you have
+ actual knowledge that, but for the patent license, your conveying the
+ covered work in a country, or your recipient's use of the covered work
+ in a country, would infringe one or more identifiable patents in that
+ country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+ arrangement, you convey, or propagate by procuring conveyance of, a
+ covered work, and grant a patent license to some of the parties
+ receiving the covered work authorizing them to use, propagate, modify
+ or convey a specific copy of the covered work, then the patent license
+ you grant is automatically extended to all recipients of the covered
+ work and works based on it.
+
+ A patent license is ``discriminatory'' if it does not include within the
+ scope of its coverage, prohibits the exercise of, or is conditioned on
+ the non-exercise of one or more of the rights that are specifically
+ granted under this License. You may not convey a covered work if you
+ are a party to an arrangement with a third party that is in the
+ business of distributing software, under which you make payment to the
+ third party based on the extent of your activity of conveying the
+ work, and under which the third party grants, to any of the parties
+ who would receive the covered work from you, a discriminatory patent
+ license (a) in connection with copies of the covered work conveyed by
+ you (or copies made from those copies), or (b) primarily for and in
+ connection with specific products or compilations that contain the
+ covered work, unless you entered into that arrangement, or that patent
+ license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+ any implied license or other defenses to infringement that may
+ otherwise be available to you under applicable patent law.
+
+ @item No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot convey
+ a covered work so as to satisfy simultaneously your obligations under
+ this License and any other pertinent obligations, then as a
+ consequence you may not convey it at all. For example, if you agree
+ to terms that obligate you to collect a royalty for further conveying
+ from those to whom you convey the Program, the only way you could
+ satisfy both those terms and this License would be to refrain entirely
+ from conveying the Program.
+
+ @item Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+ permission to link or combine any covered work with a work licensed
+ under version 3 of the GNU Affero General Public License into a single
+ combined work, and to convey the resulting work. The terms of this
+ License will continue to apply to the part which is the covered work,
+ but the special requirements of the GNU Affero General Public License,
+ section 13, concerning interaction through a network will apply to the
+ combination as such.
+
+ @item Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions
+ of the GNU General Public License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies that a certain numbered version of the GNU General Public
+ License ``or any later version'' applies to it, you have the option of
+ following the terms and conditions either of that numbered version or
+ of any later version published by the Free Software Foundation. If
+ the Program does not specify a version number of the GNU General
+ Public License, you may choose any version ever published by the Free
+ Software Foundation.
+
+ If the Program specifies that a proxy can decide which future versions
+ of the GNU General Public License can be used, that proxy's public
+ statement of acceptance of a version permanently authorizes you to
+ choose that version for the Program.
+
+ Later license versions may give you additional or different
+ permissions. However, no additional obligations are imposed on any
+ author or copyright holder as a result of your choosing to follow a
+ later version.
+
+ @item Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+ APPLICABLE LAW@. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+ HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
+ WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+ LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+ A PARTICULAR PURPOSE@. THE ENTIRE RISK AS TO THE QUALITY AND
+ PERFORMANCE OF THE PROGRAM IS WITH YOU@. SHOULD THE PROGRAM PROVE
+ DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+ CORRECTION.
+
+ @item Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+ CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+ NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+ LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+ TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+ PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+ @item Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+ above cannot be given local legal effect according to their terms,
+ reviewing courts shall apply local law that most closely approximates
+ an absolute waiver of all civil liability in connection with the
+ Program, unless a warranty or assumption of liability accompanies a
+ copy of the Program in return for a fee.

+ @heading How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these
+ terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ state the exclusion of warranty; and each file should have at least
+ the ``copyright'' line and a pointer to where the full notice is found.
+
+ @smallexample
+ @var{one line to give the program's name and a brief idea of what it does.}
+ Copyright (C) @var{year} @var{name of author}
+
+ This program is free software: you can redistribute it and/or modify

+ your option) any later version.
+
+ This program is distributed in the hope that it will be useful, but
+ WITHOUT ANY WARRANTY; without even the implied warranty of

+ @end smallexample
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+ notice like this when it starts in an interactive mode:

+ @var{program} Copyright (C) @var{year} @var{name of author}
+ This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type @samp{show c} for details.
+ @end smallexample
+
+ The hypothetical commands @samp{show w} and @samp{show c} should show
+ the appropriate parts of the General Public License. Of course, your
+ program's commands might be different; for a GUI interface, you would
+ use an ``about box''.
+
+ You should also get your employer (if you work as a programmer) or school,
+ if any, to sign a ``copyright disclaimer'' for the program, if necessary.
+ For more information on this, and how to apply and follow the GNU GPL, see

+ @display
+ Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+ @end display
+
+ @unnumberedsec Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ License is intended to guarantee your freedom to share and change free
+ software---to make sure the software is free for all its users. This
+ General Public License applies to most of the Free Software
+ Foundation's software and to any other program whose authors commit to
+ using it. (Some other Free Software Foundation software is covered by
+ the GNU Library General Public License instead.) You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must give the recipients all the rights that
+ you have. You must make sure that they, too, receive or can get the
+ source code. And you must show them these terms so they know their
+ rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+ (2) offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+ that everyone understands that there is no warranty for this free
+ software. If the software is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the original
+ authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that redistributors of a free
+ program will individually obtain patent licenses, in effect making the
+ program proprietary. To prevent this, we have made it clear that any
+ patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ @iftex
+ @unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+ @end iftex
+ @ifinfo
+ @center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+ @end ifinfo
+
+ @enumerate 0
+ @item
+ This License applies to any program or other work which contains
+ a notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The ``Program'', below,
+ refers to any such program or work, and a ``work based on the Program''
+ means either the Program or any derivative work under copyright law:
+ that is to say, a work containing the Program or a portion of it,
+ either verbatim or with modifications and/or translated into another
+ language. (Hereinafter, translation is included without limitation in
+ the term ``modification''.) Each licensee is addressed as ``you''.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the
+ Program (independent of having been made by running the Program).
+ Whether that is true depends on what the Program does.
+
+ @item
+ You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any warranty;
+ and give any other recipients of the Program a copy of this License
+ along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+ @item
+ You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ @enumerate a
+ @item
+ You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ @item
+ You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ @item
+ If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+ @end enumerate
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Program, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ @item
+ You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you also do one of the following:
+
+ @enumerate a
+ @item
+ Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ @item
+ Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ @item
+ Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+ @end enumerate
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source
+ code means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to
+ control compilation and installation of the executable. However, as a
+ special exception, the source code distributed need not include
+ anything that is normally distributed (in either source or binary
+ form) with the major components (compiler, kernel, and so on) of the
+ operating system on which the executable runs, unless that component
+ itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ @item
+ You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ @item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Program or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Program (or any work based on the
+ Program), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Program or works based on it.
+
+ @item
+ Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject to
+ these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ @item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Program at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Program by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ @item
+ If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Program under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ @item
+ The Free Software Foundation may publish revised and/or new versions
+ of the General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of this License which applies to it and ``any
+ later version'', you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Program does not specify a version number of
+ this License, you may choose any version ever published by the Free Software
+ Foundation.
+
+ @item
+ If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the author
+ to ask for permission. For software which is copyrighted by the Free
+ Software Foundation, write to the Free Software Foundation; we sometimes
+ make exceptions for this. Our decision will be guided by the two goals
+ of preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.
+
+ @center @b{NO WARRANTY}
+
+ @item
+ BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+ OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+ TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+ REPAIR OR CORRECTION.
+
+ @item
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+ OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+ TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest

+ designated Free Software Foundation software, and to any other libraries
+ whose authors decide to use it. You can use it for your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not price. Our
+ General Public Licenses are designed to make sure that you have the freedom
+ to distribute copies of free software (and charge for this service if you
+ wish), that you receive source code or can get it if you want it, that you
+ can change the software or use pieces of it in new free programs; and that
+ you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid anyone to
+ deny you these rights or to ask you to surrender the rights. These
+ restrictions translate to certain responsibilities for you if you distribute
+ copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis or for a
+ fee, you must give the recipients all the rights that we gave you. You must
+ make sure that they, too, receive or can get the source code. If you link a
+ program with the library, you must provide complete object files to the
+ recipients so that they can relink them with the library, after making
+ changes to the library and recompiling it. And you must show them these
+ terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright the
+ library, and (2) offer you this license which gives you legal permission to
+ copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain that
+ everyone understands that there is no warranty for this free library. If the
+ library is modified by someone else and passed on, we want its recipients to
+ know that what they have is not the original version, so that any problems
+ introduced by others will not reflect on the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software patents. We
+ wish to avoid the danger that companies distributing free software will
+ individually obtain patent licenses, thus in effect transforming the program
+ into proprietary software. To prevent this, we have made it clear that any
+ patent must be licensed for everyone's free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary GNU
+ General Public License, which was designed for utility programs. This
+ license, the GNU Library General Public License, applies to certain
+ designated libraries. This license is quite different from the ordinary one;
+ be sure to read it in full, and don't assume that anything in it is the same
+ as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that they
+ blur the distinction we usually make between modifying or adding to a program
+ and simply using it. Linking a program with a library, without changing the
+ library, is in some sense simply using the library, and is analogous to
+ running a utility program or application program. However, in a textual and
+ legal sense, the linked executable is a combined work, a derivative of the
+ original library, and the ordinary General Public License treats it as such.
+
+ Because of this blurred distinction, using the ordinary General Public
+ License for libraries did not effectively promote software sharing, because
+ most developers did not use the libraries. We concluded that weaker
+ conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the users of
+ those programs of all benefit from the free status of the libraries
+ themselves. This Library General Public License is intended to permit
+ developers of non-free programs to use free libraries, while preserving your
+ freedom as a user of such programs to change the free libraries that are
+ incorporated in them. (We have not seen how to achieve this as regards
+ changes in header files, but we have achieved it as regards changes in the
+ actual functions of the Library.) The hope is that this will lead to faster
+ development of free libraries.
+
+ The precise terms and conditions for copying, distribution and modification
+ follow. Pay close attention to the difference between a ``work based on the
+ library'' and a ``work that uses the library''. The former contains code
+ derived from the library, while the latter only works together with the
+ library.
+
+ Note that it is possible for a library to be covered by the ordinary General
+ Public License rather than by this special one.
+
+ \begin{center}
+ {\Large \sc Terms and Conditions For Copying, Distribution and
+ Modification}
+ \end{center}
+
+
+ \begin{enumerate}
+
+ \addtocounter{enumi}{-1}
+
+ \item
+
+ This License Agreement applies to any software library which contains a
+ notice placed by the copyright holder or other authorized party saying it
+ may be distributed under the terms of this Library General Public License
+ (also called ``this License''). Each licensee is addressed as ``you''.
+
+ A ``library'' means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The ``Library'', below, refers to any such software library or work
+ which has been distributed under these terms. A ``work based on the
+ Library'' means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term ``modification''.)
+
+ ``Source code'' for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control
+ compilation and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does and
+ what the program that uses the Library does.
+
+ \item You may copy and distribute verbatim copies of the Library's complete
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the notices
+ that refer to this License and to the absence of any warranty; and
+ distribute a copy of this License along with the Library.
+
+ You may charge a fee for the physical act of transferring a copy, and you
+ may at your option offer warranty protection in exchange for a fee.
+
+ \item
+
+ You may modify your copy or copies of the Library or any portion of it,
+ thus forming a work based on the Library, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that you
+ also meet all of these conditions:
+
+ \begin{enumerate}
+
+ \item
+
+ The modified work must itself be a software library.
+
+ \item
+
+ You must cause the files modified to carry prominent notices stating that
+ you changed the files and the date of any change.
+
+ \item
+
+ You must cause the whole of the work to be licensed at no charge to all
+ third parties under the terms of this License.
+
+ \item
+
+ If a facility in the modified Library refers to a function or a table of
+ data to be supplied by an application program that uses the facility, other
+ than as an argument passed when the facility is invoked, then you must make
+ a good faith effort to ensure that, in the event an application does not
+ supply such function or table, the facility still operates, and performs
+ whatever part of its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has a purpose
+ that is entirely well-defined independent of the application. Therefore,
+ Subsection 2d requires that any application-supplied function or table used
+ by this function must be optional: if the application does not supply it, the
+ square root function must still compute square roots.)
+
+ \end{enumerate}
+
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of a
+ storage or distribution medium does not bring the other work under the
+ scope of this License.
+
+ \item
+ You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+
+ Once this change is made in a given copy, it is irreversible for that
+ copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of the
+ Library into a program that is not a library.
+
+ \item
+ You may copy and distribute the Library (or a portion or derivative of it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you accompany it with the complete
+ corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange.
+
+ If distribution of object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ \item
+ A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a ``work that uses the Library''. Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a ``work that uses the Library'' with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a ``work that uses the
+ library''. The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a ``work that uses the Library'' uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data structure
+ layouts and accessors, and small macros and small inline functions (ten
+ lines or less in length), then the use of the object file is
+ unrestricted, regardless of whether it is legally a derivative work.
+ (Executables containing this object code plus portions of the Library
+ will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6, whether
+ or not they are linked directly with the Library itself.
+
+ \item
+
+ As an exception to the Sections above, you may also compile or
+ link a ``work that uses the Library'' with the Library to produce a
+ work containing portions of the Library, and distribute that work under
+ terms of your choice, provided that the terms permit modification of
+ the work for the customer's own use and reverse engineering for
+ debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ \begin{enumerate}
+
+ \item
+
+ Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable ``work that
+ uses the Library'', as object code and/or source code, so that
+ the user can modify the Library and then relink to produce a
+ modified executable containing the modified Library. (It is
+ understood that the user who changes the contents of definitions
+ files in the Library will not necessarily be able to recompile
+ the application to use the modified definitions.)
+
+ \item
+
+ Accompany the work with a written offer, valid for at least three
+ years, to give the same user the materials specified in
+ Subsection 6a, above, for a charge no more than the cost of
+ performing this distribution.
+
+ \item
+
+ If distribution of the work is made by offering access to
+ copy from a designated place, offer equivalent access to copy the
+ above specified materials from the same place.
+
+ \item
+
+ Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ \end{enumerate}
+
+ For an executable, the required form of the ``work that uses the
+ Library'' must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the source code distributed need not include anything that is normally
+ distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+
+ \item
+
+ You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ \begin{enumerate}
+
+ \item
+ Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ \item
+ Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ \end{enumerate}
+
+ \item
+
+ You may not copy, modify, sublicense, link with, or distribute the Library
+ except as expressly provided under this License. Any attempt otherwise
+ to copy, modify, sublicense, link with, or distribute the Library is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ \item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying the
+ Library or works based on it.
+
+ \item
+
+ Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ \item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply, and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot impose
+ that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ \item
+ If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ \item
+ The Free Software Foundation may publish revised and/or new versions
+ of the Library General Public License from time to time. Such new versions
+ will be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and ``any
+ later version'', you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Library does not specify a license version
+ number, you may choose any version ever published by the Free Software
+ Foundation.
+
+ \item
+ If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision will
+ be guided by the two goals of preserving the free status of all
+ derivatives of our free software and of promoting the sharing and reuse
+ of software generally.
+

+

+ {\sc Because the Library is licensed free of charge, there is no warranty

+ \section*{Appendix: How to Apply These Terms to Your New Libraries}
+
+ If you develop a new library, and you want it to be of the greatest possible
+ use to the public, we recommend making it free software that everyone can
+ redistribute and change. You can do so by permitting redistribution under
+ these terms (or, alternatively, under the terms of the ordinary General
+ Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ ``copyright'' line and a pointer to where the full notice is found.
+
+ \begin{verbatim}
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+
+ You should have received a copy of the GNU Library General Public License
+ along with this library; if not, write to the Free Software Foundation,
+ Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
+ \end{verbatim}
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a ``copyright disclaimer'' for the library, if
+ necessary. Here is a sample; alter the names:
+
+ \begin{verbatim}
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James
+ Random Hacker.
+

+
+ @subheading Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ Licenses are intended to guarantee your freedom to share and change
+ free software---to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+ specially designated Free Software Foundation software, and to any
+ other libraries whose authors decide to use it. You can use it for
+ your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if
+ you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+ or for a fee, you must give the recipients all the rights that we gave
+ you. You must make sure that they, too, receive or can get the source
+ code. If you link a program with the library, you must provide
+ complete object files to the recipients so that they can relink them
+ with the library, after making changes to the library and recompiling
+ it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+ the library, and (2) offer you this license which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+ that everyone understands that there is no warranty for this free
+ library. If the library is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original
+ version, so that any problems introduced by others will not reflect on
+ the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that companies distributing free
+ software will individually obtain patent licenses, thus in effect
+ transforming the program into proprietary software. To prevent this,
+ we have made it clear that any patent must be licensed for everyone's
+ free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+ GNU General Public License, which was designed for utility programs. This
+ license, the GNU Library General Public License, applies to certain
+ designated libraries. This license is quite different from the ordinary
+ one; be sure to read it in full, and don't assume that anything in it is
+ the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+ they blur the distinction we usually make between modifying or adding to a
+ program and simply using it. Linking a program with a library, without
+ changing the library, is in some sense simply using the library, and is
+ analogous to running a utility program or application program. However, in
+ a textual and legal sense, the linked executable is a combined work, a
+ derivative of the original library, and the ordinary General Public License
+ treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+ Public License for libraries did not effectively promote software
+ sharing, because most developers did not use the libraries. We
+ concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+ users of those programs of all benefit from the free status of the
+ libraries themselves. This Library General Public License is intended to
+ permit developers of non-free programs to use free libraries, while
+ preserving your freedom as a user of such programs to change the free
+ libraries that are incorporated in them. (We have not seen how to achieve
+ this as regards changes in header files, but we have achieved it as regards
+ changes in the actual functions of the Library.) The hope is that this
+ will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow. Pay close attention to the difference between a
+ ``work based on the library'' and a ``work that uses the library''. The
+ former contains code derived from the library, while the latter only
+ works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+ General Public License rather than by this special one.
+
+ @subheading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ @enumerate 0
+ @item
+ This License Agreement applies to any software library which
+ contains a notice placed by the copyright holder or other authorized
+ party saying it may be distributed under the terms of this Library
+ General Public License (also called ``this License''). Each licensee is
+ addressed as ``you''.
+
+ A ``library'' means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The ``Library'', below, refers to any such software library or work
+ which has been distributed under these terms. A ``work based on the
+ Library'' means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term ``modification''.)
+
+ ``Source code'' for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control compilation
+ and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does
+ and what the program that uses the Library does.
+
+ @item
+ You may copy and distribute verbatim copies of the Library's
+ complete source code as you receive it, in any medium, provided that
+ you conspicuously and appropriately publish on each copy an
+ appropriate copyright notice and disclaimer of warranty; keep intact
+ all the notices that refer to this License and to the absence of any
+ warranty; and distribute a copy of this License along with the
+ Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange for a
+ fee.
+
+ @item
+ You may modify your copy or copies of the Library or any portion
+ of it, thus forming a work based on the Library, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ @enumerate a
+ @item
+ The modified work must itself be a software library.
+
+ @item
+ You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ @item
+ You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ @item
+ If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+ @end enumerate
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ @item
+ You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+ that copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+ the Library into a program that is not a library.
+
+ @item
+ You may copy and distribute the Library (or a portion or
+ derivative of it, under Section 2) in object code or executable form
+ under the terms of Sections 1 and 2 above provided that you accompany
+ it with the complete corresponding machine-readable source code, which
+ must be distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+ from a designated place, then offering equivalent access to copy the
+ source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ @item
+ A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a ``work that uses the Library''. Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a ``work that uses the Library'' with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a ``work that uses the
+ library''. The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a ``work that uses the Library'' uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+ structure layouts and accessors, and small macros and small inline
+ functions (ten lines or less in length), then the use of the object
+ file is unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+
+ @item
+ As an exception to the Sections above, you may also compile or
+ link a ``work that uses the Library'' with the Library to produce a
+ work containing portions of the Library, and distribute that work
+ under terms of your choice, provided that the terms permit
+ modification of the work for the customer's own use and reverse
+ engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ @enumerate a
+ @item
+ Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable ``work that
+ uses the Library'', as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ @item
+ Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ @item
+ If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ @item
+ Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+ @end enumerate
+
+ For an executable, the required form of the ``work that uses the
+ Library'' must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the source code distributed need not include anything that is normally
+ distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+
+ @item
+ You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ @enumerate a
+ @item
+ Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ @item
+ Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+ @end enumerate
+
+ @item
+ You may not copy, modify, sublicense, link with, or distribute
+ the Library except as expressly provided under this License. Any
+ attempt otherwise to copy, modify, sublicense, link with, or
+ distribute the Library is void, and will automatically terminate your
+ rights under this License. However, parties who have received copies,
+ or rights, from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ @item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Library or works based on it.
+
+ @item
+ Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ @item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply,
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ @item
+ If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License may add
+ an explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+ @item
+ The Free Software Foundation may publish revised and/or new
+ versions of the Library General Public License from time to time.
+ Such new versions will be similar in spirit to the present version,
+ but may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and
+ ``any later version'', you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a
+ license version number, you may choose any version ever published by
+ the Free Software Foundation.
+
+ @item
+ If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free
+ Software Foundation; we sometimes make exceptions for this. Our
+ decision will be guided by the two goals of preserving the free status
+ of all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+

+
+ If you develop a new library, and you want it to be of the greatest
+ possible use to the public, we recommend making it free software that
+ everyone can redistribute and change. You can do so by permitting
+ redistribution under these terms (or, alternatively, under the terms of the
+ ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ ``copyright'' line and a pointer to where the full notice is found.

+ \begin{center}
+ {\bf\large Preamble}
+ \end{center}
+
+
+ The licenses for most software are designed to take away your freedom to
+ share and change it. By contrast, the GNU General Public Licenses are
+ intended to guarantee your freedom to share and change free software--to
+ make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some specially
+ designated software packages---typically libraries---of the Free Software
+ Foundation and other authors who decide to use it. You can use it too, but
+ we suggest you first think carefully about whether this license or the
+ ordinary General Public License is the better strategy to use in any
+ particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use, not
+ price. Our General Public Licenses are designed to make sure that you have
+ the freedom to distribute copies of free software (and charge for this
+ service if you wish); that you receive source code or can get it if you want
+ it; that you can change the software and use pieces of it in new free
+ programs; and that you are informed that you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid distributors
+ to deny you these rights or to ask you to surrender these rights. These
+ restrictions translate to certain responsibilities for you if you distribute
+ copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis or for a
+ fee, you must give the recipients all the rights that we gave you. You must
+ make sure that they, too, receive or can get the source code. If you link
+ other code with the library, you must provide complete object files to the
+ recipients, so that they can relink them with the library after making
+ changes to the library and recompiling it. And you must show them these
+ terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the library,
+ and (2) we offer you this license, which gives you legal permission to copy,
+ distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that there is no
+ warranty for the free library. Also, if the library is modified by someone
+ else and passed on, the recipients should know that what they have is not
+ the original version, so that the original author's reputation will not be
+ affected by problems that might be introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of any free
+ program. We wish to make sure that a company cannot effectively restrict the
+ users of a free program by obtaining a restrictive license from a patent
+ holder. Therefore, we insist that any patent license obtained for a version
+ of the library must be consistent with the full freedom of use specified in
+ this license.
+
+ Most GNU software, including some libraries, is covered by the ordinary GNU
+ General Public License. This license, the GNU Lesser General Public License,
+ applies to certain designated libraries, and is quite different from the
+ ordinary General Public License. We use this license for certain libraries
+ in order to permit linking those libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using a shared
+ library, the combination of the two is legally speaking a combined work, a
+ derivative of the original library. The ordinary General Public License
+ therefore permits such linking only if the entire combination fits its
+ criteria of freedom. The Lesser General Public License permits more lax
+ criteria for linking other code with the library.
+
+ We call this license the ``Lesser'' General Public License because it does
+ Less to protect the user's freedom than the ordinary General Public License.
+ It also provides other free software developers Less of an advantage over
+ competing non-free programs. These disadvantages are the reason we use the
+ ordinary General Public License for many libraries. However, the Lesser
+ license provides advantages in certain special circumstances.
+
+ For example, on rare occasions, there may be a special need to encourage the
+ widest possible use of a certain library, so that it becomes a de-facto
+ standard. To achieve this, non-free programs must be allowed to use the
+ library. A more frequent case is that a free library does the same job as
+ widely used non-free libraries. In this case, there is little to gain by
+ limiting the free library to free software only, so we use the Lesser General
+ Public License.
+
+ In other cases, permission to use a particular library in non-free programs
+ enables a greater number of people to use a large body of free software. For
+ example, permission to use the GNU C Library in non-free programs enables
+ many more people to use the whole GNU operating system, as well as its
+ variant, the GNU/Linux operating system.
+
+ Although the Lesser General Public License is Less protective of the users'
+ freedom, it does ensure that the user of a program that is linked with the
+ Library has the freedom and the wherewithal to run that program using a
+ modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and modification
+ follow. Pay close attention to the difference between a ``work based on the
+ library'' and a ``work that uses the library''. The former contains code
+ derived from the library, whereas the latter must be combined with the
+ library in order to run.
+
+ \begin{center}
+ {\Large \sc Terms and Conditions For Copying, Distribution and
+ Modification}
+ \end{center}
+
+
+ \begin{enumerate}
+
+ \addtocounter{enumi}{-1}
+
+ \item
+
+ This License Agreement applies to any software library or other program which
+ contains a notice placed by the copyright holder or other authorized party
+ saying it may be distributed under the terms of this Lesser General Public
+ License (also called ``this License''). Each licensee is addressed as
+ ``you''.
+
+ A ``library'' means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The ``Library'', below, refers to any such software library or work
+ which has been distributed under these terms. A ``work based on the
+ Library'' means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term ``modification''.)
+
+ ``Source code'' for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control
+ compilation and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does and
+ what the program that uses the Library does.
+
+ \item You may copy and distribute verbatim copies of the Library's complete
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the notices
+ that refer to this License and to the absence of any warranty; and
+ distribute a copy of this License along with the Library.
+
+ You may charge a fee for the physical act of transferring a copy, and you
+ may at your option offer warranty protection in exchange for a fee.
+
+ \item
+
+ You may modify your copy or copies of the Library or any portion of it,
+ thus forming a work based on the Library, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that you
+ also meet all of these conditions:
+
+ \begin{enumerate}
+
+ \item
+
+ The modified work must itself be a software library.
+
+ \item
+
+ You must cause the files modified to carry prominent notices stating that
+ you changed the files and the date of any change.
+
+ \item
+
+ You must cause the whole of the work to be licensed at no charge to all
+ third parties under the terms of this License.
+
+ \item
+
+ If a facility in the modified Library refers to a function or a table of
+ data to be supplied by an application program that uses the facility, other
+ than as an argument passed when the facility is invoked, then you must make
+ a good faith effort to ensure that, in the event an application does not
+ supply such function or table, the facility still operates, and performs
+ whatever part of its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has a purpose
+ that is entirely well-defined independent of the application. Therefore,
+ Subsection 2d requires that any application-supplied function or table used
+ by this function must be optional: if the application does not supply it, the
+ square root function must still compute square roots.)
+
+ \end{enumerate}
+
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of a
+ storage or distribution medium does not bring the other work under the
+ scope of this License.
+
+ \item
+ You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+
+ Once this change is made in a given copy, it is irreversible for that
+ copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of the
+ Library into a program that is not a library.
+
+ \item
+ You may copy and distribute the Library (or a portion or derivative of it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you accompany it with the complete
+ corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange.
+
+ If distribution of object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ \item
+ A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a ``work that uses the Library''. Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a ``work that uses the Library'' with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a ``work that uses the
+ library''. The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a ``work that uses the Library'' uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data structure
+ layouts and accessors, and small macros and small inline functions (ten
+ lines or less in length), then the use of the object file is
+ unrestricted, regardless of whether it is legally a derivative work.
+ (Executables containing this object code plus portions of the Library
+ will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6, whether
+ or not they are linked directly with the Library itself.
+
+ \item
+
+ As an exception to the Sections above, you may also combine or
+ link a ``work that uses the Library'' with the Library to produce a
+ work containing portions of the Library, and distribute that work under
+ terms of your choice, provided that the terms permit modification of
+ the work for the customer's own use and reverse engineering for
+ debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ \begin{enumerate}
+
+ \item
+
+ Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable ``work that
+ uses the Library'', as object code and/or source code, so that
+ the user can modify the Library and then relink to produce a
+ modified executable containing the modified Library. (It is
+ understood that the user who changes the contents of definitions
+ files in the Library will not necessarily be able to recompile
+ the application to use the modified definitions.)
+
+ \item
+
+ Use a suitable shared library mechanism for linking with the Library. A
+ suitable mechanism is one that (1) uses at run time a copy of the library
+ already present on the user's computer system, rather than copying library
+ functions into the executable, and (2) will operate properly with a modified
+ version of the library, if the user installs one, as long as the modified
+ version is interface-compatible with the version that the work was made with.
+
+ \item
+
+ Accompany the work with a written offer, valid for at least three
+ years, to give the same user the materials specified in
+ Subsection 6a, above, for a charge no more than the cost of
+ performing this distribution.
+
+ \item
+
+ If distribution of the work is made by offering access to
+ copy from a designated place, offer equivalent access to copy the
+ above specified materials from the same place.
+
+ \item
+
+ Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ \end{enumerate}
+
+ For an executable, the required form of the ``work that uses the
+ Library'' must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the materials to be distributed need not include anything that is normally
+ distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+
+ \item
+
+ You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ \begin{enumerate}
+
+ \item
+ Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ \item
+ Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ \end{enumerate}
+
+ \item
+
+ You may not copy, modify, sublicense, link with, or distribute the Library
+ except as expressly provided under this License. Any attempt otherwise
+ to copy, modify, sublicense, link with, or distribute the Library is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ \item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying the
+ Library or works based on it.
+
+ \item
+
+ Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties with
+ this License.
+
+ \item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply, and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot impose
+ that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ \item
+ If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ \item
+ The Free Software Foundation may publish revised and/or new versions
+ of the Lesser General Public License from time to time. Such new versions
+ will be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and ``any
+ later version'', you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Library does not specify a license version
+ number, you may choose any version ever published by the Free Software
+ Foundation.
+
+ \item
+ If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free Software
+ Foundation; we sometimes make exceptions for this. Our decision will
+ be guided by the two goals of preserving the free status of all
+ derivatives of our free software and of promoting the sharing and reuse
+ of software generally.
+

+ {\sc Because the Library is licensed free of charge, there is no warranty

+ \section*{Appendix: How to Apply These Terms to Your New Libraries}
+
+ If you develop a new library, and you want it to be of the greatest possible
+ use to the public, we recommend making it free software that everyone can
+ redistribute and change. You can do so by permitting redistribution under
+ these terms (or, alternatively, under the terms of the ordinary General
+ Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ ``copyright'' line and a pointer to where the full notice is found.
+
+ \begin{verbatim}
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Lesser General Public
+ License as published by the Free Software Foundation; either
+ version 2.1 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public License
+ along with this library; if not, write to the Free Software Foundation,
+ Inc., 51 Franklin Street, Fifth Floor, Boston, MA +02110-1301, USA.
+ \end{verbatim}
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a ``copyright disclaimer'' for the library, if
+ necessary. Here is a sample; alter the names:
+
+ \begin{verbatim}
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ library `Frob' (a library for tweaking knobs) written by James
+ Random Hacker.

+ of this license document, but changing it is not allowed.

+ version number 2.1.]
+ @end display
+
+ @subheading Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ Licenses are intended to guarantee your freedom to share and change
+ free software---to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+ specially designated software---typically libraries---of the Free
+ Software Foundation and other authors who decide to use it. You can use
+ it too, but we suggest you first think carefully about whether this
+ license or the ordinary General Public License is the better strategy to
+ use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+ not price. Our General Public Licenses are designed to make sure that
+ you have the freedom to distribute copies of free software (and charge
+ for this service if you wish); that you receive source code or can get
+ it if you want it; that you can change the software and use pieces of it
+ in new free programs; and that you are informed that you can do these
+ things.
+
+ To protect your rights, we need to make restrictions that forbid
+ distributors to deny you these rights or to ask you to surrender these
+ rights. These restrictions translate to certain responsibilities for
+ you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+ or for a fee, you must give the recipients all the rights that we gave
+ you. You must make sure that they, too, receive or can get the source
+ code. If you link other code with the library, you must provide
+ complete object files to the recipients, so that they can relink them
+ with the library after making changes to the library and recompiling
+ it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+ library, and (2) we offer you this license, which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+ there is no warranty for the free library. Also, if the library is
+ modified by someone else and passed on, the recipients should know
+ that what they have is not the original version, so that the original
+ author's reputation will not be affected by problems that might be
+ introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+ any free program. We wish to make sure that a company cannot
+ effectively restrict the users of a free program by obtaining a
+ restrictive license from a patent holder. Therefore, we insist that
+ any patent license obtained for a version of the library must be
+ consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ ordinary GNU General Public License. This license, the GNU Lesser
+ General Public License, applies to certain designated libraries, and
+ is quite different from the ordinary General Public License. We use
+ this license for certain libraries in order to permit linking those
+ libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+ a shared library, the combination of the two is legally speaking a
+ combined work, a derivative of the original library. The ordinary
+ General Public License therefore permits such linking only if the
+ entire combination fits its criteria of freedom. The Lesser General
+ Public License permits more lax criteria for linking other code with
+ the library.
+
+ We call this license the @dfn{Lesser} General Public License because it
+ does @emph{Less} to protect the user's freedom than the ordinary General
+ Public License. It also provides other free software developers Less
+ of an advantage over competing non-free programs. These disadvantages
+ are the reason we use the ordinary General Public License for many
+ libraries. However, the Lesser license provides advantages in certain
+ special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+ encourage the widest possible use of a certain library, so that it becomes
+ a de-facto standard. To achieve this, non-free programs must be
+ allowed to use the library. A more frequent case is that a free
+ library does the same job as widely used non-free libraries. In this
+ case, there is little to gain by limiting the free library to free
+ software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+ programs enables a greater number of people to use a large body of
+ free software. For example, permission to use the GNU C Library in
+ non-free programs enables many more people to use the whole GNU
+ operating system, as well as its variant, the GNU/Linux operating
+ system.
+
+ Although the Lesser General Public License is Less protective of the
+ users' freedom, it does ensure that the user of a program that is
+ linked with the Library has the freedom and the wherewithal to run
+ that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow. Pay close attention to the difference between a
+ ``work based on the library'' and a ``work that uses the library''. The
+ former contains code derived from the library, whereas the latter must
+ be combined with the library in order to run.
+
+ @subheading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ @enumerate 0
+ @item
+ This License Agreement applies to any software library or other program
+ which contains a notice placed by the copyright holder or other
+ authorized party saying it may be distributed under the terms of this
+ Lesser General Public License (also called ``this License''). Each
+ licensee is addressed as ``you''.
+
+ A ``library'' means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The ``Library'', below, refers to any such software library or work
+ which has been distributed under these terms. A ``work based on the
+ Library'' means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term ``modification''.)
+
+ ``Source code'' for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control compilation
+ and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does
+ and what the program that uses the Library does.
+
+ @item
+ You may copy and distribute verbatim copies of the Library's
+ complete source code as you receive it, in any medium, provided that
+ you conspicuously and appropriately publish on each copy an
+ appropriate copyright notice and disclaimer of warranty; keep intact
+ all the notices that refer to this License and to the absence of any
+ warranty; and distribute a copy of this License along with the
+ Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange for a
+ fee.
+
+ @item
+ You may modify your copy or copies of the Library or any portion
+ of it, thus forming a work based on the Library, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ @enumerate a
+ @item
+ The modified work must itself be a software library.
+
+ @item
+ You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ @item
+ You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ @item
+ If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+ @end enumerate
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ @item
+ You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+ that copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+ the Library into a program that is not a library.
+
+ @item
+ You may copy and distribute the Library (or a portion or
+ derivative of it, under Section 2) in object code or executable form
+ under the terms of Sections 1 and 2 above provided that you accompany
+ it with the complete corresponding machine-readable source code, which
+ must be distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+ from a designated place, then offering equivalent access to copy the
+ source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ @item
+ A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a ``work that uses the Library''. Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a ``work that uses the Library'' with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a ``work that uses the
+ library''. The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a ``work that uses the Library'' uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+ structure layouts and accessors, and small macros and small inline
+ functions (ten lines or less in length), then the use of the object
+ file is unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+
+ @item
+ As an exception to the Sections above, you may also combine or
+ link a ``work that uses the Library'' with the Library to produce a
+ work containing portions of the Library, and distribute that work
+ under terms of your choice, provided that the terms permit
+ modification of the work for the customer's own use and reverse
+ engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ @enumerate a
+ @item
+ Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable ``work that
+ uses the Library'', as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ @item
+ Use a suitable shared library mechanism for linking with the Library. A
+ suitable mechanism is one that (1) uses at run time a copy of the
+ library already present on the user's computer system, rather than
+ copying library functions into the executable, and (2) will operate
+ properly with a modified version of the library, if the user installs
+ one, as long as the modified version is interface-compatible with the
+ version that the work was made with.
+
+ @item
+ Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ @item
+ If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ @item
+ Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+ @end enumerate
+
+ For an executable, the required form of the ``work that uses the
+ Library'' must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the materials to be distributed need not include anything that is
+ normally distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies the
+ executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+
+ @item
+ You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ @enumerate a
+ @item
+ Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ @item
+ Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+ @end enumerate
+
+ @item
+ You may not copy, modify, sublicense, link with, or distribute
+ the Library except as expressly provided under this License. Any
+ attempt otherwise to copy, modify, sublicense, link with, or
+ distribute the Library is void, and will automatically terminate your
+ rights under this License. However, parties who have received copies,
+ or rights, from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ @item
+ You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Library or works based on it.
+
+ @item
+ Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties with
+ this License.
+
+ @item
+ If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply,
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ @item
+ If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License may add
+ an explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+ @item
+ The Free Software Foundation may publish revised and/or new
+ versions of the Lesser General Public License from time to time.
+ Such new versions will be similar in spirit to the present version,
+ but may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and
+ ``any later version'', you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a
+ license version number, you may choose any version ever published by
+ the Free Software Foundation.
+
+ @item
+ If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free
+ Software Foundation; we sometimes make exceptions for this. Our
+ decision will be guided by the two goals of preserving the free status
+ of all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ @center @b{NO WARRANTY}
+
+ @item
+ BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+ EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+ OTHER PARTIES PROVIDE THE LIBRARY ``AS IS'' WITHOUT WARRANTY OF ANY
+ KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+ IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+ LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+ THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ @item
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+ AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+ FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+ CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+ LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+ RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A

+ @subheading How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+ possible use to the public, we recommend making it free software that
+ everyone can redistribute and change. You can do so by permitting
+ redistribution under these terms (or, alternatively, under the terms of the
+ ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ ``copyright'' line and a pointer to where the full notice is found.
+
+ @smallexample
+ @var{one line to give the library's name and an idea of what it does.}
+ Copyright (C) @var{year} @var{name of author}
+
+ This library is free software; you can redistribute it and/or modify it
+ under the terms of the GNU Lesser General Public License as published by
+ the Free Software Foundation; either version 2.1 of the License, or (at
+ your option) any later version.
+
+ This library is distributed in the hope that it will be useful, but
+ WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Lesser General Public License for more details.
+
+ You should have received a copy of the GNU Lesser General Public
+ License along with this library; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301,
+ USA.
+ @end smallexample
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a ``copyright disclaimer'' for the library, if
+ necessary. Here is a sample; alter the names:
+
+ @smallexample

+
+
+ This version of the GNU Lesser General Public License incorporates
+ the terms and conditions of version 3 of the GNU General Public
+ License, supplemented by the additional permissions listed below.
+
+ \begin{enumerate}
+ \addtocounter{enumi}{-1} % start at 0
+
+ \item Additional Definitions.
+
+ As used herein, ``this License'' refers to version 3 of the GNU Lesser
+ General Public License, and the ``GNU GPL'' refers to version 3 of the GNU
+ General Public License.
+
+ ``The Library'' refers to a covered work governed by this License,
+ other than an Application or a Combined Work as defined below.
+
+ An ``Application'' is any work that makes use of an interface provided
+ by the Library, but which is not otherwise based on the Library.
+ Defining a subclass of a class defined by the Library is deemed a mode
+ of using an interface provided by the Library.
+
+ A ``Combined Work'' is a work produced by combining or linking an
+ Application with the Library. The particular version of the Library
+ with which the Combined Work was made is also called the ``Linked
+ Version''.
+
+ The ``Minimal Corresponding Source'' for a Combined Work means the
+ Corresponding Source for the Combined Work, excluding any source code
+ for portions of the Combined Work that, considered in isolation, are
+ based on the Application, and not on the Linked Version.
+
+ The ``Corresponding Application Code'' for a Combined Work means the
+ object code and/or source code for the Application, including any data
+ and utility programs needed for reproducing the Combined Work from the
+ Application, but excluding the System Libraries of the Combined Work.
+
+ \item Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+ without being bound by section 3 of the GNU GPL.
+
+ \item Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+ facility refers to a function or data to be supplied by an Application
+ that uses the facility (other than as an argument passed when the
+ facility is invoked), then you may convey a copy of the modified
+ version:
+
+ \begin{enumerate}
+ \item under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ \item under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+ \end{enumerate}
+
+ \item Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+ a header file that is part of the Library. You may convey such object
+ code under terms of your choice, provided that, if the incorporated
+ material is not limited to numerical parameters, data structure
+ layouts and accessors, or small macros, inline functions and templates
+ (ten or fewer lines in length), you do both of the following:
+
+ \begin{enumerate}
+ \item Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ \item Accompany the object code with a copy of the GNU GPL and this license
+ document.
+ \end{enumerate}
+
+ \item Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+ taken together, effectively do not restrict modification of the
+ portions of the Library contained in the Combined Work and reverse
+ engineering for debugging such modifications, if you also do each of
+ the following:
+
+ \begin{enumerate}
+ \item Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ \item Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ \item For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ \item Do one of the following:
+
+ \begin{enumerate}
+ \addtocounter{enumiii}{-1} % start at 0
+ \item Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ \item Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+ \end{enumerate}
+
+ \item Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+ \end{enumerate}
+
+ \item Combined Libraries.
+
+ You may place library facilities that are a work based on the
+ Library side by side in a single library together with other library
+ facilities that are not Applications and are not covered by this
+ License, and convey such a combined library under terms of your
+ choice, if you do both of the following:
+
+ \begin{enumerate}
+ \item Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ \item Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+ \end{enumerate}
+
+ \item Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+ of the GNU Lesser General Public License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+ Library as you received it specifies that a certain numbered version
+ of the GNU Lesser General Public License ``or any later version''
+ applies to it, you have the option of following the terms and
+ conditions either of that published version or of any later version
+ published by the Free Software Foundation. If the Library as you
+ received it does not specify a version number of the GNU Lesser
+ General Public License, you may choose any version of the GNU Lesser
+ General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+ whether future versions of the GNU Lesser General Public License shall
+ apply, that proxy's public statement of acceptance of any version is
+ permanent authorization for you to choose that version for the
+ Library.

++### SYNOPSIS
++###
++### mdw_AUTO_VERSION
++###
++### DESCRIPTION
++###
++### Defines an m4 macro `AUTO_VERSION' which contains the current package's
++### version number, worked out in some clever way.
++###
++### The heavy lifting is performed by the `auto-version' script (q.v.). In
++### brief:
++###
++### * if this is a Git working tree (i.e., there is a `.git' file or
++### directory at toplevel) then call `git describe' and use its output;
++###
++### * if there is a `RELEASE' file, then use its contents literally;
++###
++### * if there is a `debian/changelog' file, then use the most recent
++### entry's version number;
++###
++### * otherwise use `UNKNOWN'.

++###
++### mdw_PROG(PROG)
++### mdw_PATH(PATH)
++### mdw_DEFINE_PROG(SYMBOL, PROG)
++### mdw_DEFINE_PATH(SYMBOL, PATH)
++###
++### DESCRIPTION
++###
++### This collection of macros is useful for hardcoding pathname strings
++### into binary programs.
++###
++### Within the BODY of `mdw_DEFINE_PATHS', a number of variables are `fixed
++### up' so that they can be properly expanded. The other macros are only
++### really useful within this body.
++###
++### `mdw_PROG' expands, in the shell, to the transformed name of the
++### program PROG.
++###
++### `mdw_PATH' expands, in the shell, to the recursive expansion of PATH,
++### which should be a string containing parameter expansions.
++###
++### `mdw_DEFINE_PROG' is a convenience macro which defines the preprocessor
++### SYMBOL to the result of `mdw_PROG(PROG)'; similarly `mdw_DEFINE_PATH'
++### defines SYMBOL to the result of `mdw_PATH(PATH)'.

+ *
+ * The precise manner of options parsing is determined by
+ * various flag settings, which are described below. By setting
+ * flag values appropriately, you can achieve behaviour very
+ * similar to most other getopt routines.
+ *
+ *
+ * How options parsing appears to users
+ *
+ * A command line consists of a number of `words' (which may
+ * contain spaces, according to various shell quoting
+ * conventions). A word may be an option, an argument to an
+ * option, or a non-option. An option begins with a special
+ * character, usually `%|-|%', although `%|+|%' is also used
+ * sometimes. As special exceptions, the word containing only a
+ * `%|-|%' is considered to be a non-option, since it usually
+ * represents standard input or output as a filename, and the
+ * word containing a double-dash `%|--|%' is used to mark all
+ * following words as being non-options regardless of their
+ * initial character.
+ *
+ * Traditionally, all words after the first non-option have been
+ * considered to be non-options automatically, so that options
+ * must be specified before filenames. However, this
+ * implementation can extract all the options from the command
+ * line regardless of their position. This can usually be
+ * disabled by setting one of the environment variables
+ * `%|POSIXLY_CORRECT|%' or `%|_POSIX_OPTION_ORDER|%'.
+ *
+ * There are two different styles of options: `short' and
+ * `long'.
+ *
+ * Short options are the sort which Unix has known for ages: an
+ * option is a single letter, preceded by a `%|-|%'. Short
+ * options can be joined together to save space (and possibly to
+ * make silly words): e.g., instead of giving options
+ * `%|-x -y|%', a user could write `%|-xy|%'. Some short
+ * options can have arguments, which appear after the option
+ * letter, either immediately following, or in the next `word'
+ * (so an option with an argument could be written as
+ * `%|-o foo|%' or as `%|-ofoo|%'). Note that options with
+ * optional arguments must be written in the second style.
+ *
+ * When a short option controls a flag setting, it is sometimes
+ * possible to explicitly turn the flag off, as well as turning
+ * it on, (usually to override default options). This is
+ * usually done by using a `%|+|%' instead of a `%|-|%' to
+ * introduce the option.
+ *
+ * Long options, as popularized by the GNU utilities, are given
+ * long-ish memorable names, preceded by a double-dash `%|--|%'.
+ * Since their names are more than a single character, long
+ * options can't be combined in the same way as short options.
+ * Arguments to long options may be given either in the same
+ * `word', separated from the option name by an equals sign, or
+ * in the following `word'.
+ *
+ * Long option names can be abbreviated if necessary, as long
+ * as the abbreviation is unique. This means that options can
+ * have sensible and memorable names but still not require much
+ * typing from an experienced user.
+ *
+ * Like short options, long options can control flag settings.
+ * The options to manipulate these settings come in pairs: an
+ * option of the form `%|--set-flag|%' might set the flag, while
+ * an option of the form `%|--no-set-flag|%' might clear it.
+ *
+ * It is usual for applications to provide both short and long
+ * options with identical behaviour. Some applications with
+ * lots of options may only provide long options (although they
+ * will often be only two or three characters long). In this
+ * case, long options can be preceded with a single `%|-|%'
+ * character, and negated by a `%|+|%' character.
+ *
+ * Finally, some (older) programs accept arguments of the form
+ * `%%@.{"-"<number>}%%', to set some numerical parameter,
+ * typically a line count of some kind.
+ *
+ *
+ * How programs parse options
+ *
+ * An application parses its options by calling mdwopt
+ * repeatedly. Each time it is called, mdwopt returns a value
+ * describing the option just read, and stores information about
+ * the option in a data block. The value %$-1$% is returned
+ * when there are no more options to be read. The `%|?|%'
+ * character is returned when an error is encountered.
+ *
+ * Before starting to parse options, the value @data->ind@ must
+ * be set to 0 or 1. The value of @data->err@ can also be set,
+ * to choose whether errors are reported by mdwopt.
+ *
+ * The program's `@argc@' and `@argv@' arguments are passed to
+ * the options parser, so that it can read the command line. A
+ * flags word is also passed, allowing the program fine control
+ * over parsing. The flags are described above.
+ *
+ * Short options are described by a string, which once upon a
+ * time just contained the permitted option characters. Now the
+ * options string begins with a collection of flag characters,
+ * and various flag characters can be put after options
+ * characters to change their properties.
+ *
+ * If the first character of the short options string is
+ * `%|+|%', `%|-|%' or `%|!|%', the order in which options are
+ * read is modified, as follows:
+ *
+ * `%|+|%' forces the POSIX order to be used. As soon as a non-
+ * option is found, mdwopt returns %$-1$%.
+ *
+ * `%|-|%' makes mdwopt treat non-options as being `special'
+ * sorts of option. When a non-option word is found, the
+ * value 0 is returned, and the actual text of the word
+ * is stored as being the option's argument.
+ *
+ * `%|!|%' forces the default order to be used. The entire
+ * command line is scanned for options, which are
+ * returned in order. However, during this process,
+ * the options are moved in the @argv@ array, so that
+ * they appear before the non- options.
+ *
+ * A `%|:|%' character may be placed after the ordering flag (or
+ * at the very beginning if no ordering flag is given) which
+ * indicates that the character `%|:|%', rather than `%|?|%',
+ * should be returned if a missing argument error is detected.
+ *
+ * Each option in the string can be followed by a `%|+|%' sign,
+ * indicating that it can be negated, a `%|:|%' sign indicating
+ * that it requires an argument, or a `%|::|%' string,
+ * indicating an optional argument. Both `%|+|%' and `%|:|%' or
+ * `%|::|%' may be given, although the `%|+|%' must come first.
+ *
+ * If an option is found, the option character is returned to
+ * the caller. A pointer to an argument is stored in
+ * @data->arg@, or @NULL@ is stored if there was no argument.
+ * If a negated option was found, the option character is
+ * returned ORred with @OPTF_NEGATED@ (bit 8 set).
+ *
+ * Long options are described in a table. Each entry in the
+ * table is of type @struct option@, and the table is terminated
+ * by an entry whose @name@ field is null. Each option has
+ * a flags word which, due to historical reasons, is called
+ * @has_arg@. This describes various properties of the option,
+ * such as what sort of argument it takes, and whether it can
+ * be negated.
+ *
+ * When mdwopt finds a long option, it looks the name up in the
+ * table. The index of the matching entry is stored in the
+ * @longind@ variable, passed to mdwopt (unless @longind@ is 0):
+ * a value of %$-1$% indicates that no long option was
+ * found. The behaviour is then dependent on the values in the
+ * table entry. If @flag@ is nonzero, it points to an integer
+ * to be modified by mdwopt. Usually the value in the @val@
+ * field is simply stored in the @flag@ variable. If the flag
+ * @OPTF_SWITCH@ is set, however, the value is combined with
+ * the existing value of the flags using a bitwise OR. If
+ * @OPTF_NEGATE@ is set, then the flag bit will be cleared if a
+ * matching negated long option is found. The value 0 is
+ * returned.
+ *
+ * If @flag@ is zero, the value in @val@ is returned by mdwopt,
+ * possibly with bit 8 set if the option was negated.
+ *
+ * Arguments for long options are stored in @data->arg@, as
+ * before.
+ *
+ * Numeric options, if enabled, cause the value `%|#|%' to be
+ * returned, and the numeric value to be stored in @data->opt@.
+ *
+ * If the flag @OPTF_ENVVAR@ is set on entry, options will be
+ * extracted from an environment variable whose name is built by
+ * capitalizing all the letters of the program's name. (This
+ * allows a user to have different default settings for a
+ * program, by calling it through different symbolic links.)

+ *
+ * Use: Reads options. The routine should be more-or-less compatible
+ * with standard getopts, although it provides many more
+ * features even than the standard GNU implementation.
+ *
+ * The precise manner of options parsing is determined by
+ * various flag settings, which are described below. By setting
+ * flag values appropriately, you can achieve behaviour very
+ * similar to most other getopt routines.
+ *
+ *
+ * How options parsing appears to users
+ *
+ * A command line consists of a number of `words' (which may
+ * contain spaces, according to various shell quoting
+ * conventions). A word may be an option, an argument to an
+ * option, or a non-option. An option begins with a special
+ * character, usually `%|-|%', although `%|+|%' is also used
+ * sometimes. As special exceptions, the word containing only a
+ * `%|-|%' is considered to be a non-option, since it usually
+ * represents standard input or output as a filename, and the
+ * word containing a double-dash `%|--|%' is used to mark all
+ * following words as being non-options regardless of their
+ * initial character.
+ *
+ * Traditionally, all words after the first non-option have been
+ * considered to be non-options automatically, so that options
+ * must be specified before filenames. However, this
+ * implementation can extract all the options from the command
+ * line regardless of their position. This can usually be
+ * disabled by setting one of the environment variables
+ * `%|POSIXLY_CORRECT|%' or `%|_POSIX_OPTION_ORDER|%'.
+ *
+ * There are two different styles of options: `short' and
+ * `long'.
+ *
+ * Short options are the sort which Unix has known for ages: an
+ * option is a single letter, preceded by a `%|-|%'. Short
+ * options can be joined together to save space (and possibly to
+ * make silly words): e.g., instead of giving options
+ * `%|-x.-y|%', a user could write `%|-xy|%'. Some short
+ * options can have arguments, which appear after the option
+ * letter, either immediately following, or in the next `word'
+ * (so an option with an argument could be written as
+ * `%|-o foo|%' or as `%|-ofoo|%'). Note that options with
+ * optional arguments must be written in the second style.
+ *
+ * When a short option controls a flag setting, it is sometimes
+ * possible to explicitly turn the flag off, as well as turning
+ * it on, (usually to override default options). This is
+ * usually done by using a `%|+|%' instead of a `%|-|%' to
+ * introduce the option.
+ *
+ * Long options, as popularized by the GNU utilities, are given
+ * long-ish memorable names, preceded by a double-dash `%|--|%'.
+ * Since their names are more than a single character, long
+ * options can't be combined in the same way as short options.
+ * Arguments to long options may be given either in the same
+ * `word', separated from the option name by an equals sign, or
+ * in the following `word'.
+ *
+ * Long option names can be abbreviated if necessary, as long
+ * as the abbreviation is unique. This means that options can
+ * have sensible and memorable names but still not require much
+ * typing from an experienced user.
+ *
+ * Like short options, long options can control flag settings.
+ * The options to manipulate these settings come in pairs: an
+ * option of the form `%|--set-flag|%' might set the flag, while
+ * an option of the form `%|--no-set-flag|%' might clear it.
+ *
+ * It is usual for applications to provide both short and long
+ * options with identical behaviour. Some applications with
+ * lots of options may only provide long options (although they
+ * will often be only two or three characters long). In this
+ * case, long options can be preceded with a single `%|-|%'
+ * character, and negated by a `%|+|%' character.
+ *
+ * Finally, some (older) programs accept arguments of the form
+ * `%%@.{"-"<number>}%%', to set some numerical parameter,
+ * typically a line count of some kind.
+ *
+ *
+ * How programs parse options
+ *
+ * An application parses its options by calling mdwopt
+ * repeatedly. Each time it is called, mdwopt returns a value
+ * describing the option just read, and stores information about
+ * the option in a data block. The value %$-1$% is returned
+ * when there are no more options to be read. The `%|?|%'
+ * character is returned when an error is encountered.
+ *
+ * Before starting to parse options, the value @data->ind@ must
+ * be set to 0 or 1. The value of @data->err@ can also be set,
+ * to choose whether errors are reported by mdwopt.
+ *
+ * The program's `@argc@' and `@argv@' arguments are passed to
+ * the options parser, so that it can read the command line. A
+ * flags word is also passed, allowing the program fine control
+ * over parsing. The flags are described above.
+ *
+ * Short options are described by a string, which once upon a
+ * time just contained the permitted option characters. Now the
+ * options string begins with a collection of flag characters,
+ * and various flag characters can be put after options
+ * characters to change their properties.
+ *
+ * If the first character of the short options string is
+ * `%|+|%', `%|-|%' or `%|!|%', the order in which options are
+ * read is modified, as follows:
+ *
+ * `%|+|%' forces the POSIX order to be used. As soon as a non-
+ * option is found, mdwopt returns %$-1$%.
+ *
+ * `%|-|%' makes mdwopt treat non-options as being `special'
+ * sorts of option. When a non-option word is found, the
+ * value 0 is returned, and the actual text of the word
+ * is stored as being the option's argument.
+ *
+ * `%|!|%' forces the default order to be used. The entire
+ * command line is scanned for options, which are
+ * returned in order. However, during this process,
+ * the options are moved in the @argv@ array, so that
+ * they appear before the non- options.
+ *
+ * A `%|:|%' character may be placed after the ordering flag (or
+ * at the very beginning if no ordering flag is given) which
+ * indicates that the character `%|:|%', rather than `%|?|%',
+ * should be returned if a missing argument error is detected.
+ *
+ * Each option in the string can be followed by a `%|+|%' sign,
+ * indicating that it can be negated, a `%|:|%' sign indicating
+ * that it requires an argument, or a `%|::|%' string,
+ * indicating an optional argument. Both `%|+|%' and `%|:|%' or
+ * `%|::|%' may be given, although the `%|+|%' must come first.
+ *
+ * If an option is found, the option character is returned to
+ * the caller. A pointer to an argument is stored in
+ * @data->arg@, or @NULL@ is stored if there was no argument.
+ * If a negated option was found, the option character is
+ * returned ORred with @OPTF_NEGATED@ (bit 8 set).
+ *
+ * Long options are described in a table. Each entry in the
+ * table is of type @struct option@, and the table is terminated
+ * by an entry whose @name@ field is null. Each option has
+ * a flags word which, due to historical reasons, is called
+ * @has_arg@. This describes various properties of the option,
+ * such as what sort of argument it takes, and whether it can
+ * be negated.
+ *
+ * When mdwopt finds a long option, it looks the name up in the
+ * table. The index of the matching entry is stored in the
+ * @longind@ variable, passed to mdwopt (unless @longind@ is 0):
+ * a value of %$-1$% indicates that no long option was
+ * found. The behaviour is then dependent on the values in the
+ * table entry. If @flag@ is nonzero, it points to an integer
+ * to be modified by mdwopt. Usually the value in the @val@
+ * field is simply stored in the @flag@ variable. If the flag
+ * @OPTF_SWITCH@ is set, however, the value is combined with
+ * the existing value of the flags using a bitwise OR. If
+ * @OPTF_NEGATE@ is set, then the flag bit will be cleared if a
+ * matching negated long option is found. The value 0 is
+ * returned.
+ *
+ * If @flag@ is zero, the value in @val@ is returned by mdwopt,
+ * possibly with bit 8 set if the option was negated.
+ *
+ * Arguments for long options are stored in @data->arg@, as
+ * before.
+ *
+ * Numeric options, if enabled, cause the value `%|#|%' to be
+ * returned, and the numeric value to be stored in @data->opt@.
+ *
+ * If the flag @OPTF_ENVVAR@ is set on entry, options will be
+ * extracted from an environment variable whose name is built by
+ * capitalizing all the letters of the program's name. (This
+ * allows a user to have different default settings for a
+ * program, by calling it through different symbolic links.)
