75\begin{abstract}
76The GNU General Public License is a free, copyleft license for
77software and other kinds of works.
78
79The licenses for most software and other practical works are designed
80to take away your freedom to share and change the works. By contrast,
81the GNU General Public License is intended to guarantee your freedom to
82share and change all versions of a program--to make sure it remains free
83software for all its users. We, the Free Software Foundation, use the
84GNU General Public License for most of our software; it applies also to
85any other work released this way by its authors. You can apply it to
86your programs, too.
87
88When we speak of free software, we are referring to freedom, not
89price. Our General Public Licenses are designed to make sure that you
90have the freedom to distribute copies of free software (and charge for
91them if you wish), that you receive source code or can get it if you
92want it, that you can change the software or use pieces of it in new
93free programs, and that you know you can do these things.
94
95To protect your rights, we need to prevent others from denying you
96these rights or asking you to surrender the rights. Therefore, you have
97certain responsibilities if you distribute copies of the software, or if
98you modify it: responsibilities to respect the freedom of others.
99
100For example, if you distribute copies of such a program, whether
101gratis or for a fee, you must pass on to the recipients the same
102freedoms that you received. You must make sure that they, too, receive
103or can get the source code. And you must show them these terms so they
104know their rights.
105
106Developers that use the GNU GPL protect your rights with two steps:
107(1) assert copyright on the software, and (2) offer you this License
108giving you legal permission to copy, distribute and/or modify it.
109
110For the developers' and authors' protection, the GPL clearly explains
111that there is no warranty for this free software. For both users' and
112authors' sake, the GPL requires that modified versions be marked as
113changed, so that their problems will not be attributed erroneously to
114authors of previous versions.
115
116Some devices are designed to deny users access to install or run
117modified versions of the software inside them, although the manufacturer
118can do so. This is fundamentally incompatible with the aim of
119protecting users' freedom to change the software. The systematic
120pattern of such abuse occurs in the area of products for individuals to
121use, which is precisely where it is most unacceptable. Therefore, we
122have designed this version of the GPL to prohibit the practice for those
123products. If such problems arise substantially in other domains, we
124stand ready to extend this provision to those domains in future versions
125of the GPL, as needed to protect the freedom of users.
126
127Finally, every program is threatened constantly by software patents.
128States should not allow patents to restrict development and use of
129software on general-purpose computers, but in those that do, we wish to
130avoid the special danger that patents applied to a free program could
131make it effectively proprietary. To prevent this, the GPL assures that
132patents cannot be used to render the program non-free.
133
134The precise terms and conditions for copying, distribution and
135modification follow.

146
147\item Definitions.
148
149``This License'' refers to version 3 of the GNU General Public License.
150
151``Copyright'' also means copyright-like laws that apply to other kinds of
152works, such as semiconductor masks.
153
154``The Program'' refers to any copyrightable work licensed under this
155License. Each licensee is addressed as ``you''. ``Licensees'' and
156``recipients'' may be individuals or organizations.
157
158To ``modify'' a work means to copy from or adapt all or part of the work
159in a fashion requiring copyright permission, other than the making of an
160exact copy. The resulting work is called a ``modified version'' of the
161earlier work or a work ``based on'' the earlier work.
162
163A ``covered work'' means either the unmodified Program or a work based
164on the Program.
165
166To ``propagate'' a work means to do anything with it that, without
167permission, would make you directly or secondarily liable for
168infringement under applicable copyright law, except executing it on a
169computer or modifying a private copy. Propagation includes copying,
170distribution (with or without modification), making available to the
171public, and in some countries other activities as well.
172
173To ``convey'' a work means any kind of propagation that enables other
174parties to make or receive copies. Mere interaction with a user through
175a computer network, with no transfer of a copy, is not conveying.
176
177An interactive user interface displays ``Appropriate Legal Notices''
178to the extent that it includes a convenient and prominently visible
179feature that (1) displays an appropriate copyright notice, and (2)
180tells the user that there is no warranty for the work (except to the
181extent that warranties are provided), that licensees may convey the
182work under this License, and how to view a copy of this License. If
183the interface presents a list of user commands or options, such as a
184menu, a prominent item in the list meets this criterion.
185
186\item Source Code.
187
188The ``source code'' for a work means the preferred form of the work
189for making modifications to it. ``Object code'' means any non-source
190form of a work.
191
192A ``Standard Interface'' means an interface that either is an official
193standard defined by a recognized standards body, or, in the case of
194interfaces specified for a particular programming language, one that
195is widely used among developers working in that language.
196
197The ``System Libraries'' of an executable work include anything, other
198than the work as a whole, that (a) is included in the normal form of
199packaging a Major Component, but which is not part of that Major
200Component, and (b) serves only to enable use of the work with that
201Major Component, or to implement a Standard Interface for which an
202implementation is available to the public in source code form. A
203``Major Component'', in this context, means a major essential component
204(kernel, window system, and so on) of the specific operating system
205(if any) on which the executable work runs, or a compiler used to
206produce the work, or an object code interpreter used to run it.
207
208The ``Corresponding Source'' for a work in object code form means all
209the source code needed to generate, install, and (for an executable
210work) run the object code and to modify the work, including scripts to
211control those activities. However, it does not include the work's
212System Libraries, or general-purpose tools or generally available free
213programs which are used unmodified in performing those activities but
214which are not part of the work. For example, Corresponding Source
215includes interface definition files associated with source files for
216the work, and the source code for shared libraries and dynamically
217linked subprograms that the work is specifically designed to require,
218such as by intimate data communication or control flow between those
219subprograms and other parts of the work.
220
221The Corresponding Source need not include anything that users
222can regenerate automatically from other parts of the Corresponding
223Source.
224
225The Corresponding Source for a work in source code form is that
226same work.
227
228\item Basic Permissions.
229
230All rights granted under this License are granted for the term of
231copyright on the Program, and are irrevocable provided the stated
232conditions are met. This License explicitly affirms your unlimited
233permission to run the unmodified Program. The output from running a
234covered work is covered by this License only if the output, given its
235content, constitutes a covered work. This License acknowledges your
236rights of fair use or other equivalent, as provided by copyright law.
237
238You may make, run and propagate covered works that you do not
239convey, without conditions so long as your license otherwise remains
240in force. You may convey covered works to others for the sole purpose
241of having them make modifications exclusively for you, or provide you
242with facilities for running those works, provided that you comply with
243the terms of this License in conveying all material for which you do
244not control copyright. Those thus making or running the covered works
245for you must do so exclusively on your behalf, under your direction
246and control, on terms that prohibit them from making any copies of
247your copyrighted material outside their relationship with you.
248
249Conveying under any other circumstances is permitted solely under
250the conditions stated below. Sublicensing is not allowed; section 10
251makes it unnecessary.
252
253\item Protecting Users' Legal Rights From Anti-Circumvention Law.
254
255No covered work shall be deemed part of an effective technological
256measure under any applicable law fulfilling obligations under article
25711 of the WIPO copyright treaty adopted on 20 December 1996, or
258similar laws prohibiting or restricting circumvention of such
259measures.
260
261When you convey a covered work, you waive any legal power to forbid
262circumvention of technological measures to the extent such circumvention
263is effected by exercising rights under this License with respect to
264the covered work, and you disclaim any intention to limit operation or
265modification of the work as a means of enforcing, against the work's
266users, your or third parties' legal rights to forbid circumvention of
267technological measures.
268
269\item Conveying Verbatim Copies.
270
271You may convey verbatim copies of the Program's source code as you
272receive it, in any medium, provided that you conspicuously and
273appropriately publish on each copy an appropriate copyright notice;
274keep intact all notices stating that this License and any
275non-permissive terms added in accord with section 7 apply to the code;
276keep intact all notices of the absence of any warranty; and give all
277recipients a copy of this License along with the Program.
278
279You may charge any price or no price for each copy that you convey,
280and you may offer support or warranty protection for a fee.
281
282\item Conveying Modified Source Versions.
283
284You may convey a work based on the Program, or the modifications to
285produce it from the Program, in the form of source code under the
286terms of section 4, provided that you also meet all of these conditions:
287 \begin{enumerate}
288 \item The work must carry prominent notices stating that you modified
289 it, and giving a relevant date.
290
291 \item The work must carry prominent notices stating that it is
292 released under this License and any conditions added under section
293 7. This requirement modifies the requirement in section 4 to
294 ``keep intact all notices''.
295
296 \item You must license the entire work, as a whole, under this
297 License to anyone who comes into possession of a copy. This
298 License will therefore apply, along with any applicable section 7
299 additional terms, to the whole of the work, and all its parts,
300 regardless of how they are packaged. This License gives no
301 permission to license the work in any other way, but it does not
302 invalidate such permission if you have separately received it.
303
304 \item If the work has interactive user interfaces, each must display
305 Appropriate Legal Notices; however, if the Program has interactive
306 interfaces that do not display Appropriate Legal Notices, your
307 work need not make them do so.
308\end{enumerate}
309A compilation of a covered work with other separate and independent
310works, which are not by their nature extensions of the covered work,
311and which are not combined with it such as to form a larger program,
312in or on a volume of a storage or distribution medium, is called an
313``aggregate'' if the compilation and its resulting copyright are not
314used to limit the access or legal rights of the compilation's users
315beyond what the individual works permit. Inclusion of a covered work
316in an aggregate does not cause this License to apply to the other
317parts of the aggregate.
318
319\item Conveying Non-Source Forms.
320
321You may convey a covered work in object code form under the terms
322of sections 4 and 5, provided that you also convey the
323machine-readable Corresponding Source under the terms of this License,
324in one of these ways:
325 \begin{enumerate}
326 \item Convey the object code in, or embodied in, a physical product
327 (including a physical distribution medium), accompanied by the
328 Corresponding Source fixed on a durable physical medium
329 customarily used for software interchange.
330
331 \item Convey the object code in, or embodied in, a physical product
332 (including a physical distribution medium), accompanied by a
333 written offer, valid for at least three years and valid for as
334 long as you offer spare parts or customer support for that product
335 model, to give anyone who possesses the object code either (1) a
336 copy of the Corresponding Source for all the software in the
337 product that is covered by this License, on a durable physical
338 medium customarily used for software interchange, for a price no
339 more than your reasonable cost of physically performing this
340 conveying of source, or (2) access to copy the
341 Corresponding Source from a network server at no charge.
342
343 \item Convey individual copies of the object code with a copy of the
344 written offer to provide the Corresponding Source. This
345 alternative is allowed only occasionally and noncommercially, and
346 only if you received the object code with such an offer, in accord
347 with subsection 6b.
348
349 \item Convey the object code by offering access from a designated
350 place (gratis or for a charge), and offer equivalent access to the
351 Corresponding Source in the same way through the same place at no
352 further charge. You need not require recipients to copy the
353 Corresponding Source along with the object code. If the place to
354 copy the object code is a network server, the Corresponding Source
355 may be on a different server (operated by you or a third party)
356 that supports equivalent copying facilities, provided you maintain
357 clear directions next to the object code saying where to find the
358 Corresponding Source. Regardless of what server hosts the
359 Corresponding Source, you remain obligated to ensure that it is
360 available for as long as needed to satisfy these requirements.
361
362 \item Convey the object code using peer-to-peer transmission, provided
363 you inform other peers where the object code and Corresponding
364 Source of the work are being offered to the general public at no
365 charge under subsection 6d.
366 \end{enumerate}
367
368A separable portion of the object code, whose source code is excluded
369from the Corresponding Source as a System Library, need not be
370included in conveying the object code work.
371
372A ``User Product'' is either (1) a ``consumer product'', which means any
373tangible personal property which is normally used for personal, family,
374or household purposes, or (2) anything designed or sold for incorporation
375into a dwelling. In determining whether a product is a consumer product,
376doubtful cases shall be resolved in favor of coverage. For a particular
377product received by a particular user, ``normally used'' refers to a
378typical or common use of that class of product, regardless of the status
379of the particular user or of the way in which the particular user
380actually uses, or expects or is expected to use, the product. A product
381is a consumer product regardless of whether the product has substantial
382commercial, industrial or non-consumer uses, unless such uses represent
383the only significant mode of use of the product.
384
385``Installation Information'' for a User Product means any methods,
386procedures, authorization keys, or other information required to install
387and execute modified versions of a covered work in that User Product from
388a modified version of its Corresponding Source. The information must
389suffice to ensure that the continued functioning of the modified object
390code is in no case prevented or interfered with solely because
391modification has been made.
392
393If you convey an object code work under this section in, or with, or
394specifically for use in, a User Product, and the conveying occurs as
395part of a transaction in which the right of possession and use of the
396User Product is transferred to the recipient in perpetuity or for a
397fixed term (regardless of how the transaction is characterized), the
398Corresponding Source conveyed under this section must be accompanied
399by the Installation Information. But this requirement does not apply
400if neither you nor any third party retains the ability to install
401modified object code on the User Product (for example, the work has
402been installed in ROM).
403
404The requirement to provide Installation Information does not include a
405requirement to continue to provide support service, warranty, or updates
406for a work that has been modified or installed by the recipient, or for
407the User Product in which it has been modified or installed. Access to a
408network may be denied when the modification itself materially and
409adversely affects the operation of the network or violates the rules and
410protocols for communication across the network.
411
412Corresponding Source conveyed, and Installation Information provided,
413in accord with this section must be in a format that is publicly
414documented (and with an implementation available to the public in
415source code form), and must require no special password or key for
416unpacking, reading or copying.
417
418\item Additional Terms.
419
420``Additional permissions'' are terms that supplement the terms of this
421License by making exceptions from one or more of its conditions.
422Additional permissions that are applicable to the entire Program shall
423be treated as though they were included in this License, to the extent
424that they are valid under applicable law. If additional permissions
425apply only to part of the Program, that part may be used separately
426under those permissions, but the entire Program remains governed by
427this License without regard to the additional permissions.
428
429When you convey a copy of a covered work, you may at your option
430remove any additional permissions from that copy, or from any part of
431it. (Additional permissions may be written to require their own
432removal in certain cases when you modify the work.) You may place
433additional permissions on material, added by you to a covered work,
434for which you have or can give appropriate copyright permission.
435
436Notwithstanding any other provision of this License, for material you
437add to a covered work, you may (if authorized by the copyright holders of
438that material) supplement the terms of this License with terms:
439 \begin{enumerate}
440 \item Disclaiming warranty or limiting liability differently from the
441 terms of sections 15 and 16 of this License; or
442
443 \item Requiring preservation of specified reasonable legal notices or
444 author attributions in that material or in the Appropriate Legal
445 Notices displayed by works containing it; or
446
447 \item Prohibiting misrepresentation of the origin of that material, or
448 requiring that modified versions of such material be marked in
449 reasonable ways as different from the original version; or
450
451 \item Limiting the use for publicity purposes of names of licensors or
452 authors of the material; or
453
454 \item Declining to grant rights under trademark law for use of some
455 trade names, trademarks, or service marks; or
456
457 \item Requiring indemnification of licensors and authors of that
458 material by anyone who conveys the material (or modified versions of
459 it) with contractual assumptions of liability to the recipient, for
460 any liability that these contractual assumptions directly impose on
461 those licensors and authors.
462 \end{enumerate}
463
464All other non-permissive additional terms are considered ``further
465restrictions'' within the meaning of section 10. If the Program as you
466received it, or any part of it, contains a notice stating that it is
467governed by this License along with a term that is a further
468restriction, you may remove that term. If a license document contains
469a further restriction but permits relicensing or conveying under this
470License, you may add to a covered work material governed by the terms
471of that license document, provided that the further restriction does
472not survive such relicensing or conveying.
473
474If you add terms to a covered work in accord with this section, you
475must place, in the relevant source files, a statement of the
476additional terms that apply to those files, or a notice indicating
477where to find the applicable terms.
478
479Additional terms, permissive or non-permissive, may be stated in the
480form of a separately written license, or stated as exceptions;
481the above requirements apply either way.
482
483\item Termination.
484
485You may not propagate or modify a covered work except as expressly
486provided under this License. Any attempt otherwise to propagate or
487modify it is void, and will automatically terminate your rights under
488this License (including any patent licenses granted under the third
489paragraph of section 11).
490
491However, if you cease all violation of this License, then your
492license from a particular copyright holder is reinstated (a)
493provisionally, unless and until the copyright holder explicitly and
494finally terminates your license, and (b) permanently, if the copyright
495holder fails to notify you of the violation by some reasonable means
496prior to 60 days after the cessation.
497
498Moreover, your license from a particular copyright holder is
499reinstated permanently if the copyright holder notifies you of the
500violation by some reasonable means, this is the first time you have
501received notice of violation of this License (for any work) from that
502copyright holder, and you cure the violation prior to 30 days after
503your receipt of the notice.
504
505Termination of your rights under this section does not terminate the
506licenses of parties who have received copies or rights from you under
507this License. If your rights have been terminated and not permanently
508reinstated, you do not qualify to receive new licenses for the same
509material under section 10.
510
511\item Acceptance Not Required for Having Copies.
512
513You are not required to accept this License in order to receive or
514run a copy of the Program. Ancillary propagation of a covered work
515occurring solely as a consequence of using peer-to-peer transmission
516to receive a copy likewise does not require acceptance. However,
517nothing other than this License grants you permission to propagate or
518modify any covered work. These actions infringe copyright if you do
519not accept this License. Therefore, by modifying or propagating a
520covered work, you indicate your acceptance of this License to do so.
521
522\item Automatic Licensing of Downstream Recipients.
523
524Each time you convey a covered work, the recipient automatically
525receives a license from the original licensors, to run, modify and
526propagate that work, subject to this License. You are not responsible
527for enforcing compliance by third parties with this License.
528
529An ``entity transaction'' is a transaction transferring control of an
530organization, or substantially all assets of one, or subdividing an
531organization, or merging organizations. If propagation of a covered
532work results from an entity transaction, each party to that
533transaction who receives a copy of the work also receives whatever
534licenses to the work the party's predecessor in interest had or could
535give under the previous paragraph, plus a right to possession of the
536Corresponding Source of the work from the predecessor in interest, if
537the predecessor has it or can get it with reasonable efforts.
538
539You may not impose any further restrictions on the exercise of the
540rights granted or affirmed under this License. For example, you may
541not impose a license fee, royalty, or other charge for exercise of
542rights granted under this License, and you may not initiate litigation
543(including a cross-claim or counterclaim in a lawsuit) alleging that
544any patent claim is infringed by making, using, selling, offering for
545sale, or importing the Program or any portion of it.
546
547\item Patents.
548
549A ``contributor'' is a copyright holder who authorizes use under this
550License of the Program or a work on which the Program is based. The
551work thus licensed is called the contributor's ``contributor version''.
552
553A contributor's ``essential patent claims'' are all patent claims
554owned or controlled by the contributor, whether already acquired or
555hereafter acquired, that would be infringed by some manner, permitted
556by this License, of making, using, or selling its contributor version,
557but do not include claims that would be infringed only as a
558consequence of further modification of the contributor version. For
559purposes of this definition, ``control'' includes the right to grant
560patent sublicenses in a manner consistent with the requirements of
561this License.
562
563Each contributor grants you a non-exclusive, worldwide, royalty-free
564patent license under the contributor's essential patent claims, to
565make, use, sell, offer for sale, import and otherwise run, modify and
566propagate the contents of its contributor version.
567
568In the following three paragraphs, a ``patent license'' is any express
569agreement or commitment, however denominated, not to enforce a patent
570(such as an express permission to practice a patent or covenant not to
571sue for patent infringement). To ``grant'' such a patent license to a
572party means to make such an agreement or commitment not to enforce a
573patent against the party.
574
575If you convey a covered work, knowingly relying on a patent license,
576and the Corresponding Source of the work is not available for anyone
577to copy, free of charge and under the terms of this License, through a
578publicly available network server or other readily accessible means,
579then you must either (1) cause the Corresponding Source to be so
580available, or (2) arrange to deprive yourself of the benefit of the
581patent license for this particular work, or (3) arrange, in a manner
582consistent with the requirements of this License, to extend the patent
583license to downstream recipients. ``Knowingly relying'' means you have
584actual knowledge that, but for the patent license, your conveying the
585covered work in a country, or your recipient's use of the covered work
586in a country, would infringe one or more identifiable patents in that
587country that you have reason to believe are valid.
588
589If, pursuant to or in connection with a single transaction or
590arrangement, you convey, or propagate by procuring conveyance of, a
591covered work, and grant a patent license to some of the parties
592receiving the covered work authorizing them to use, propagate, modify
593or convey a specific copy of the covered work, then the patent license
594you grant is automatically extended to all recipients of the covered
595work and works based on it.
596
597A patent license is ``discriminatory'' if it does not include within
598the scope of its coverage, prohibits the exercise of, or is
599conditioned on the non-exercise of one or more of the rights that are
600specifically granted under this License. You may not convey a covered
601work if you are a party to an arrangement with a third party that is
602in the business of distributing software, under which you make payment
603to the third party based on the extent of your activity of conveying
604the work, and under which the third party grants, to any of the
605parties who would receive the covered work from you, a discriminatory
606patent license (a) in connection with copies of the covered work
607conveyed by you (or copies made from those copies), or (b) primarily
608for and in connection with specific products or compilations that
609contain the covered work, unless you entered into that arrangement,
610or that patent license was granted, prior to 28 March 2007.
611
612Nothing in this License shall be construed as excluding or limiting
613any implied license or other defenses to infringement that may
614otherwise be available to you under applicable patent law.
615
616\item No Surrender of Others' Freedom.
617
618If conditions are imposed on you (whether by court order, agreement or
619otherwise) that contradict the conditions of this License, they do not
620excuse you from the conditions of this License. If you cannot convey a
621covered work so as to satisfy simultaneously your obligations under this
622License and any other pertinent obligations, then as a consequence you may
623not convey it at all. For example, if you agree to terms that obligate you
624to collect a royalty for further conveying from those to whom you convey
625the Program, the only way you could satisfy both those terms and this
626License would be to refrain entirely from conveying the Program.
627
628\item Use with the GNU Affero General Public License.
629
630Notwithstanding any other provision of this License, you have
631permission to link or combine any covered work with a work licensed
632under version 3 of the GNU Affero General Public License into a single
633combined work, and to convey the resulting work. The terms of this
634License will continue to apply to the part which is the covered work,
635but the special requirements of the GNU Affero General Public License,
636section 13, concerning interaction through a network will apply to the
637combination as such.
638
639\item Revised Versions of this License.
640
641The Free Software Foundation may publish revised and/or new versions of
642the GNU General Public License from time to time. Such new versions will
643be similar in spirit to the present version, but may differ in detail to
644address new problems or concerns.
645
646Each version is given a distinguishing version number. If the
647Program specifies that a certain numbered version of the GNU General
648Public License ``or any later version'' applies to it, you have the
649option of following the terms and conditions either of that numbered
650version or of any later version published by the Free Software
651Foundation. If the Program does not specify a version number of the
652GNU General Public License, you may choose any version ever published
653by the Free Software Foundation.
654
655If the Program specifies that a proxy can decide which future
656versions of the GNU General Public License can be used, that proxy's
657public statement of acceptance of a version permanently authorizes you
658to choose that version for the Program.
659
660Later license versions may give you additional or different
661permissions. However, no additional obligations are imposed on any
662author or copyright holder as a result of your choosing to follow a
663later version.
664
665\item Disclaimer of Warranty.
666
667\begin{sloppypar}
668 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
669 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
670 COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
671 WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
672 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
673 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
674 RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
675 SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
676 NECESSARY SERVICING, REPAIR OR CORRECTION.
677\end{sloppypar}
678
679\item Limitation of Liability.
680
681 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
682 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
683 AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
684 DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
685 DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
686 (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
687 INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
688 OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
689 HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
690 DAMAGES.
691
692\item Interpretation of Sections 15 and 16.
693
694If the disclaimer of warranty and limitation of liability provided
695above cannot be given local legal effect according to their terms,
696reviewing courts shall apply local law that most closely approximates
697an absolute waiver of all civil liability in connection with the
698Program, unless a warranty or assumption of liability accompanies a
699copy of the Program in return for a fee.

705How to Apply These Terms to Your New Programs
706\end{center}
707
708If you develop a new program, and you want it to be of the greatest
709possible use to the public, the best way to achieve this is to make it
710free software which everyone can redistribute and change under these terms.
711
712To do so, attach the following notices to the program. It is safest
713to attach them to the start of each source file to most effectively
714state the exclusion of warranty; and each file should have at least
715the ``copyright'' line and a pointer to where the full notice is found.
716
717{\footnotesize
718\begin{verbatim}

721Copyright (C) <textyear> <name of author>
722
723This program is free software: you can redistribute it and/or modify
724it under the terms of the GNU General Public License as published by
725the Free Software Foundation, either version 3 of the License, or
726(at your option) any later version.
727
728This program is distributed in the hope that it will be useful,
729but WITHOUT ANY WARRANTY; without even the implied warranty of
730MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
731GNU General Public License for more details.
732
733You should have received a copy of the GNU General Public License
734along with this program. If not, see <http://www.gnu.org/licenses/>.
735\end{verbatim}
736}
737
738Also add information on how to contact you by electronic and paper mail.
739
740If the program does terminal interaction, make it output a short
741notice like this when it starts in an interactive mode:
742
743{\footnotesize
744\begin{verbatim}
745<program> Copyright (C) <year> <name of author>
746
747This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
748This is free software, and you are welcome to redistribute it
749under certain conditions; type `show c' for details.
750\end{verbatim}
751}
752
753The hypothetical commands {\tt show w} and {\tt show c} should show
754the appropriate
755parts of the General Public License. Of course, your program's commands
756might be different; for a GUI interface, you would use an ``about box''.
757
758You should also get your employer (if you work as a programmer) or
759school, if any, to sign a ``copyright disclaimer'' for the program, if
760necessary. For more information on this, and how to apply and follow
761the GNU GPL, see \texttt{http://www.gnu.org/licenses/}.
762
763The GNU General Public License does not permit incorporating your
764program into proprietary programs. If your program is a subroutine
765library, you may consider it more useful to permit linking proprietary
766applications with the library. If this is what you want to do, use
767the GNU Lesser General Public License instead of this License. But
768first, please read \texttt{http://www.gnu.org/philosophy/why-not-lgpl.html}.
