Subject: [PATCH] Reinstate erroneously deleted `*.tex' and `*.texi' files.

The previous commit contained part of a reorganization effort.
Unfortunately, it only contained the part which broke everything.
Reinstate the missing things.

+\gplsec{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.
+
+
+\gplsec{Terms and conditions for copying, distribution and modification}
+
+\begin{enumerate}
+
+\makeatletter \setcounter{\@listctr}{-1} \makeatother
+
+\item [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.
+
+\item [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.
+
+\item [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:
+
+      \begin{enumerate}
+
+      \item [(a)] You must cause the modified files to carry prominent
+            notices stating that you changed the files and the date of any
+            change.
+
+      \item [(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.
+
+      \item [(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.)
+
+      \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 [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:
+
+      \begin{enumerate}
+
+      \item [(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,
+
+      \item [(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,
+
+      \item [(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.)
+
+      \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 [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\begin{center}
+NO WARRANTY
+\end{center}
+
+\bfseries
+
+\item [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.
+
+\item [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.

+\gplsec{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{verbatim}
+<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
+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., 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.
+
+If the program is interactive, make it output a short notice like this when
+it starts in an interactive mode:
+
+\begin{verbatim}
+Gnomovision version 69, Copyright (C) 19yy 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{verbatim}
+
+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 is a sample; alter the names:
+
+\begin{verbatim}
+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{verbatim}
+
+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.

+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.

+BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

+@unnumberedsec 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.
+

+
+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 is interactive, make it output a short notice like this
+when it starts in an interactive mode:

+Gnomovision comes with ABSOLUTELY NO WARRANTY; for details

+to redistribute it under certain conditions; type `show c'
+for details.

+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License.  Of course, the
+commands you use may be called something other than @samp{show w} and
+@samp{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:

+Public License instead of this License.

+\textbf{GNU LIBRARY GENERAL PUBLIC LICENSE} \\
+Version 2, June 1991
+\end{center}

+\begin{center}
+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 \\

+
+
+\gplsec{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.
+
+
+\gplsec{Terms and conditions for copying, distribution and modification}
+
+\begin{enumerate}
+
+\makeatletter \setcounter{\@listctr}{-1} \makeatother
+
+\item [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.
+
+\item [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.
+
+\item [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:
+
+      \begin{enumerate}
+
+      \item [(a)] The modified work must itself be a software library.
+
+      \item [(b)] You must cause the files modified to carry prominent
+            notices stating that you changed the files and the date of any
+            change.
+
+      \item [(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.
+
+      \item [(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.)
+
+      \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 [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.
+
+      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 [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.
+
+\item [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.
+
+\item [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:
+
+      \begin{enumerate}
+
+      \item [(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.)
+
+      \item [(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.
+
+      \item [(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.
+
+      \item [(d)] 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 [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:
+
+      \begin{enumerate}
+
+      \item [(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.
+
+      \item [(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.
+
+      \end{enumerate}
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\item [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.
+
+\begin{center}
+NO WARRANTY
+\end{center}
+
+\bfseries
+
+\item [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.
+
+\item [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.

+\gplsec{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

+
+@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
+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.

+@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.

+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.

+@unnumberedsec 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.}
