25GNU GENERAL PUBLIC LICENSE
26==========================
27Version 3, 29 June 2007
28=======================
29
30> Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
31 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
32
33# Preamble
34
35 The GNU General Public License is a free, copyleft license for
36software and other kinds of works.
37
38 The licenses for most software and other practical works are designed
39to take away your freedom to share and change the works. By contrast,
40the GNU General Public License is intended to guarantee your freedom to
41share and change all versions of a program--to make sure it remains free
42software for all its users. We, the Free Software Foundation, use the
43GNU General Public License for most of our software; it applies also to
44any other work released this way by its authors. You can apply it to
45your programs, too.
46
47 When we speak of free software, we are referring to freedom, not
48price. Our General Public Licenses are designed to make sure that you
49have the freedom to distribute copies of free software (and charge for
50them if you wish), that you receive source code or can get it if you
51want it, that you can change the software or use pieces of it in new
52free programs, and that you know you can do these things.
53
54 To protect your rights, we need to prevent others from denying you
55these rights or asking you to surrender the rights. Therefore, you have
56certain responsibilities if you distribute copies of the software, or if
57you modify it: responsibilities to respect the freedom of others.
58
59 For example, if you distribute copies of such a program, whether
60gratis or for a fee, you must pass on to the recipients the same
61freedoms that you received. You must make sure that they, too, receive
62or can get the source code. And you must show them these terms so they
63know their rights.
64
65 Developers that use the GNU GPL protect your rights with two steps:
66(1) assert copyright on the software, and (2) offer you this License
67giving you legal permission to copy, distribute and/or modify it.
68
69 For the developers' and authors' protection, the GPL clearly explains
70that there is no warranty for this free software. For both users' and
71authors' sake, the GPL requires that modified versions be marked as
72changed, so that their problems will not be attributed erroneously to
73authors of previous versions.
74
75 Some devices are designed to deny users access to install or run
76modified versions of the software inside them, although the manufacturer
77can do so. This is fundamentally incompatible with the aim of
78protecting users' freedom to change the software. The systematic
79pattern of such abuse occurs in the area of products for individuals to
80use, which is precisely where it is most unacceptable. Therefore, we
81have designed this version of the GPL to prohibit the practice for those
82products. If such problems arise substantially in other domains, we
83stand ready to extend this provision to those domains in future versions
84of the GPL, as needed to protect the freedom of users.
85
86 Finally, every program is threatened constantly by software patents.
87States should not allow patents to restrict development and use of
88software on general-purpose computers, but in those that do, we wish to
89avoid the special danger that patents applied to a free program could
90make it effectively proprietary. To prevent this, the GPL assures that
91patents cannot be used to render the program non-free.
92
93 The precise terms and conditions for copying, distribution and
94modification follow.
95
96# TERMS AND CONDITIONS
97
98## 0. Definitions.
99
100 _"This License"_ refers to version 3 of the GNU General Public License.
101
102 _"Copyright"_ also means copyright-like laws that apply to other kinds of
103works, such as semiconductor masks.
104
105 _"The Program"_ refers to any copyrightable work licensed under this
106License. Each licensee is addressed as _"you"_. _"Licensees"_ and
107"recipients" may be individuals or organizations.
108
109 To _"modify"_ a work means to copy from or adapt all or part of the work
110in a fashion requiring copyright permission, other than the making of an
111exact copy. The resulting work is called a _"modified version"_ of the
112earlier work or a work _"based on"_ the earlier work.
113
114 A _"covered work"_ means either the unmodified Program or a work based
115on the Program.
116
117 To _"propagate"_ a work means to do anything with it that, without
118permission, would make you directly or secondarily liable for
119infringement under applicable copyright law, except executing it on a
120computer or modifying a private copy. Propagation includes copying,
121distribution (with or without modification), making available to the
122public, and in some countries other activities as well.
123
124 To _"convey"_ a work means any kind of propagation that enables other
125parties to make or receive copies. Mere interaction with a user through
126a computer network, with no transfer of a copy, is not conveying.
127
128 An interactive user interface displays "Appropriate Legal Notices"
129to the extent that it includes a convenient and prominently visible
130feature that (1) displays an appropriate copyright notice, and (2)
131tells the user that there is no warranty for the work (except to the
132extent that warranties are provided), that licensees may convey the
133work under this License, and how to view a copy of this License. If
134the interface presents a list of user commands or options, such as a
135menu, a prominent item in the list meets this criterion.
136
137## 1. Source Code.
138
139 The _"source code"_ for a work means the preferred form of the work
140for making modifications to it. _"Object code"_ means any non-source
141form of a work.
142
143 A _"Standard Interface"_ means an interface that either is an official
144standard defined by a recognized standards body, or, in the case of
145interfaces specified for a particular programming language, one that
146is widely used among developers working in that language.
147
148 The _"System Libraries"_ of an executable work include anything, other
149than the work as a whole, that (a) is included in the normal form of
150packaging a Major Component, but which is not part of that Major
151Component, and (b) serves only to enable use of the work with that
152Major Component, or to implement a Standard Interface for which an
153implementation is available to the public in source code form. A
154"Major Component", in this context, means a major essential component
155(kernel, window system, and so on) of the specific operating system
156(if any) on which the executable work runs, or a compiler used to
157produce the work, or an object code interpreter used to run it.
158
159 The _"Corresponding Source"_ for a work in object code form means all
160the source code needed to generate, install, and (for an executable
161work) run the object code and to modify the work, including scripts to
162control those activities. However, it does not include the work's
163System Libraries, or general-purpose tools or generally available free
164programs which are used unmodified in performing those activities but
165which are not part of the work. For example, Corresponding Source
166includes interface definition files associated with source files for
167the work, and the source code for shared libraries and dynamically
168linked subprograms that the work is specifically designed to require,
169such as by intimate data communication or control flow between those
170subprograms and other parts of the work.
171
172 The Corresponding Source need not include anything that users
173can regenerate automatically from other parts of the Corresponding
174Source.
175
176 The Corresponding Source for a work in source code form is that
177same work.
178
179## 2. Basic Permissions.
180
181 All rights granted under this License are granted for the term of
182copyright on the Program, and are irrevocable provided the stated
183conditions are met. This License explicitly affirms your unlimited
184permission to run the unmodified Program. The output from running a
185covered work is covered by this License only if the output, given its
186content, constitutes a covered work. This License acknowledges your
187rights of fair use or other equivalent, as provided by copyright law.
188
189 You may make, run and propagate covered works that you do not
190convey, without conditions so long as your license otherwise remains
191in force. You may convey covered works to others for the sole purpose
192of having them make modifications exclusively for you, or provide you
193with facilities for running those works, provided that you comply with
194the terms of this License in conveying all material for which you do
195not control copyright. Those thus making or running the covered works
196for you must do so exclusively on your behalf, under your direction
197and control, on terms that prohibit them from making any copies of
198your copyrighted material outside their relationship with you.
199
200 Conveying under any other circumstances is permitted solely under
201the conditions stated below. Sublicensing is not allowed; section 10
202makes it unnecessary.
203
204## 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
205
206 No covered work shall be deemed part of an effective technological
207measure under any applicable law fulfilling obligations under article
20811 of the WIPO copyright treaty adopted on 20 December 1996, or
209similar laws prohibiting or restricting circumvention of such
210measures.
211
212 When you convey a covered work, you waive any legal power to forbid
213circumvention of technological measures to the extent such circumvention
214is effected by exercising rights under this License with respect to
215the covered work, and you disclaim any intention to limit operation or
216modification of the work as a means of enforcing, against the work's
217users, your or third parties' legal rights to forbid circumvention of
218technological measures.
219
220## 4. Conveying Verbatim Copies.
221
222 You may convey verbatim copies of the Program's source code as you
223receive it, in any medium, provided that you conspicuously and
224appropriately publish on each copy an appropriate copyright notice;
225keep intact all notices stating that this License and any
226non-permissive terms added in accord with section 7 apply to the code;
227keep intact all notices of the absence of any warranty; and give all
228recipients a copy of this License along with the Program.
229
230 You may charge any price or no price for each copy that you convey,
231and you may offer support or warranty protection for a fee.
232
233## 5. Conveying Modified Source Versions.
234
235 You may convey a work based on the Program, or the modifications to
236produce it from the Program, in the form of source code under the
237terms of section 4, provided that you also meet all of these conditions:
238
239 a) The work must carry prominent notices stating that you modified
240 it, and giving a relevant date.
241
242 b) The work must carry prominent notices stating that it is
243 released under this License and any conditions added under section
244 7. This requirement modifies the requirement in section 4 to
245 "keep intact all notices".
246
247 c) You must license the entire work, as a whole, under this
248 License to anyone who comes into possession of a copy. This
249 License will therefore apply, along with any applicable section 7
250 additional terms, to the whole of the work, and all its parts,
251 regardless of how they are packaged. This License gives no
252 permission to license the work in any other way, but it does not
253 invalidate such permission if you have separately received it.
254
255 d) If the work has interactive user interfaces, each must display
256 Appropriate Legal Notices; however, if the Program has interactive
257 interfaces that do not display Appropriate Legal Notices, your
258 work need not make them do so.
259
260 A compilation of a covered work with other separate and independent
261works, which are not by their nature extensions of the covered work,
262and which are not combined with it such as to form a larger program,
263in or on a volume of a storage or distribution medium, is called an
264"aggregate" if the compilation and its resulting copyright are not
265used to limit the access or legal rights of the compilation's users
266beyond what the individual works permit. Inclusion of a covered work
267in an aggregate does not cause this License to apply to the other
268parts of the aggregate.
269
270## 6. Conveying Non-Source Forms.
271
272 You may convey a covered work in object code form under the terms
273of sections 4 and 5, provided that you also convey the
274machine-readable Corresponding Source under the terms of this License,
275in one of these ways:
276
277 a) Convey the object code in, or embodied in, a physical product
278 (including a physical distribution medium), accompanied by the
279 Corresponding Source fixed on a durable physical medium
280 customarily used for software interchange.
281
282 b) Convey the object code in, or embodied in, a physical product
283 (including a physical distribution medium), accompanied by a
284 written offer, valid for at least three years and valid for as
285 long as you offer spare parts or customer support for that product
286 model, to give anyone who possesses the object code either (1) a
287 copy of the Corresponding Source for all the software in the
288 product that is covered by this License, on a durable physical
289 medium customarily used for software interchange, for a price no
290 more than your reasonable cost of physically performing this
291 conveying of source, or (2) access to copy the
292 Corresponding Source from a network server at no charge.
293
294 c) Convey individual copies of the object code with a copy of the
295 written offer to provide the Corresponding Source. This
296 alternative is allowed only occasionally and noncommercially, and
297 only if you received the object code with such an offer, in accord
298 with subsection 6b.
299
300 d) Convey the object code by offering access from a designated
301 place (gratis or for a charge), and offer equivalent access to the
302 Corresponding Source in the same way through the same place at no
303 further charge. You need not require recipients to copy the
304 Corresponding Source along with the object code. If the place to
305 copy the object code is a network server, the Corresponding Source
306 may be on a different server (operated by you or a third party)
307 that supports equivalent copying facilities, provided you maintain
308 clear directions next to the object code saying where to find the
309 Corresponding Source. Regardless of what server hosts the
310 Corresponding Source, you remain obligated to ensure that it is
311 available for as long as needed to satisfy these requirements.
312
313 e) Convey the object code using peer-to-peer transmission, provided
314 you inform other peers where the object code and Corresponding
315 Source of the work are being offered to the general public at no
316 charge under subsection 6d.
317
318 A separable portion of the object code, whose source code is excluded
319from the Corresponding Source as a System Library, need not be
320included in conveying the object code work.
321
322 A _"User Product"_ is either (1) a _"consumer product"_, which means any
323tangible personal property which is normally used for personal, family,
324or household purposes, or (2) anything designed or sold for incorporation
325into a dwelling. In determining whether a product is a consumer product,
326doubtful cases shall be resolved in favor of coverage. For a particular
327product received by a particular user, "normally used" refers to a
328typical or common use of that class of product, regardless of the status
329of the particular user or of the way in which the particular user
330actually uses, or expects or is expected to use, the product. A product
331is a consumer product regardless of whether the product has substantial
332commercial, industrial or non-consumer uses, unless such uses represent
333the only significant mode of use of the product.
334
335 _"Installation Information"_ for a User Product means any methods,
336procedures, authorization keys, or other information required to install
337and execute modified versions of a covered work in that User Product from
338a modified version of its Corresponding Source. The information must
339suffice to ensure that the continued functioning of the modified object
340code is in no case prevented or interfered with solely because
341modification has been made.
342
343 If you convey an object code work under this section in, or with, or
344specifically for use in, a User Product, and the conveying occurs as
345part of a transaction in which the right of possession and use of the
346User Product is transferred to the recipient in perpetuity or for a
347fixed term (regardless of how the transaction is characterized), the
348Corresponding Source conveyed under this section must be accompanied
349by the Installation Information. But this requirement does not apply
350if neither you nor any third party retains the ability to install
351modified object code on the User Product (for example, the work has
352been installed in ROM).
353
354 The requirement to provide Installation Information does not include a
355requirement to continue to provide support service, warranty, or updates
356for a work that has been modified or installed by the recipient, or for
357the User Product in which it has been modified or installed. Access to a
358network may be denied when the modification itself materially and
359adversely affects the operation of the network or violates the rules and
360protocols for communication across the network.
361
362 Corresponding Source conveyed, and Installation Information provided,
363in accord with this section must be in a format that is publicly
364documented (and with an implementation available to the public in
365source code form), and must require no special password or key for
366unpacking, reading or copying.
367
368## 7. Additional Terms.
369
370 _"Additional permissions"_ are terms that supplement the terms of this
371License by making exceptions from one or more of its conditions.
372Additional permissions that are applicable to the entire Program shall
373be treated as though they were included in this License, to the extent
374that they are valid under applicable law. If additional permissions
375apply only to part of the Program, that part may be used separately
376under those permissions, but the entire Program remains governed by
377this License without regard to the additional permissions.
378
379 When you convey a copy of a covered work, you may at your option
380remove any additional permissions from that copy, or from any part of
381it. (Additional permissions may be written to require their own
382removal in certain cases when you modify the work.) You may place
383additional permissions on material, added by you to a covered work,
384for which you have or can give appropriate copyright permission.
385
386 Notwithstanding any other provision of this License, for material you
387add to a covered work, you may (if authorized by the copyright holders of
388that material) supplement the terms of this License with terms:
389
390 a) Disclaiming warranty or limiting liability differently from the
391 terms of sections 15 and 16 of this License; or
392
393 b) Requiring preservation of specified reasonable legal notices or
394 author attributions in that material or in the Appropriate Legal
395 Notices displayed by works containing it; or
396
397 c) Prohibiting misrepresentation of the origin of that material, or
398 requiring that modified versions of such material be marked in
399 reasonable ways as different from the original version; or
400
401 d) Limiting the use for publicity purposes of names of licensors or
402 authors of the material; or
403
404 e) Declining to grant rights under trademark law for use of some
405 trade names, trademarks, or service marks; or
406
407 f) Requiring indemnification of licensors and authors of that
408 material by anyone who conveys the material (or modified versions of
409 it) with contractual assumptions of liability to the recipient, for
410 any liability that these contractual assumptions directly impose on
411 those licensors and authors.
412
413 All other non-permissive additional terms are considered "further
414restrictions" within the meaning of section 10. If the Program as you
415received it, or any part of it, contains a notice stating that it is
416governed by this License along with a term that is a further
417restriction, you may remove that term. If a license document contains
418a further restriction but permits relicensing or conveying under this
419License, you may add to a covered work material governed by the terms
420of that license document, provided that the further restriction does
421not survive such relicensing or conveying.
422
423 If you add terms to a covered work in accord with this section, you
424must place, in the relevant source files, a statement of the
425additional terms that apply to those files, or a notice indicating
426where to find the applicable terms.
427
428 Additional terms, permissive or non-permissive, may be stated in the
429form of a separately written license, or stated as exceptions;
430the above requirements apply either way.
431
432## 8. Termination.
433
434 You may not propagate or modify a covered work except as expressly
435provided under this License. Any attempt otherwise to propagate or
436modify it is void, and will automatically terminate your rights under
437this License (including any patent licenses granted under the third
438paragraph of section 11).
439
440 However, if you cease all violation of this License, then your
441license from a particular copyright holder is reinstated (a)
442provisionally, unless and until the copyright holder explicitly and
443finally terminates your license, and (b) permanently, if the copyright
444holder fails to notify you of the violation by some reasonable means
445prior to 60 days after the cessation.
446
447 Moreover, your license from a particular copyright holder is
448reinstated permanently if the copyright holder notifies you of the
449violation by some reasonable means, this is the first time you have
450received notice of violation of this License (for any work) from that
451copyright holder, and you cure the violation prior to 30 days after
452your receipt of the notice.
453
454 Termination of your rights under this section does not terminate the
455licenses of parties who have received copies or rights from you under
456this License. If your rights have been terminated and not permanently
457reinstated, you do not qualify to receive new licenses for the same
458material under section 10.
459
460## 9. Acceptance Not Required for Having Copies.
461
462 You are not required to accept this License in order to receive or
463run a copy of the Program. Ancillary propagation of a covered work
464occurring solely as a consequence of using peer-to-peer transmission
465to receive a copy likewise does not require acceptance. However,
466nothing other than this License grants you permission to propagate or
467modify any covered work. These actions infringe copyright if you do
468not accept this License. Therefore, by modifying or propagating a
469covered work, you indicate your acceptance of this License to do so.
470
471## 10. Automatic Licensing of Downstream Recipients.
472
473 Each time you convey a covered work, the recipient automatically
474receives a license from the original licensors, to run, modify and
475propagate that work, subject to this License. You are not responsible
476for enforcing compliance by third parties with this License.
477
478 An _"entity transaction"_ is a transaction transferring control of an
479organization, or substantially all assets of one, or subdividing an
480organization, or merging organizations. If propagation of a covered
481work results from an entity transaction, each party to that
482transaction who receives a copy of the work also receives whatever
483licenses to the work the party's predecessor in interest had or could
484give under the previous paragraph, plus a right to possession of the
485Corresponding Source of the work from the predecessor in interest, if
486the predecessor has it or can get it with reasonable efforts.
487
488 You may not impose any further restrictions on the exercise of the
489rights granted or affirmed under this License. For example, you may
490not impose a license fee, royalty, or other charge for exercise of
491rights granted under this License, and you may not initiate litigation
492(including a cross-claim or counterclaim in a lawsuit) alleging that
493any patent claim is infringed by making, using, selling, offering for
494sale, or importing the Program or any portion of it.
495
496## 11. Patents.
497
498 A _"contributor"_ is a copyright holder who authorizes use under this
499License of the Program or a work on which the Program is based. The
500work thus licensed is called the contributor's "contributor version".
501
502 A contributor's _"essential patent claims"_ are all patent claims
503owned or controlled by the contributor, whether already acquired or
504hereafter acquired, that would be infringed by some manner, permitted
505by this License, of making, using, or selling its contributor version,
506but do not include claims that would be infringed only as a
507consequence of further modification of the contributor version. For
508purposes of this definition, "control" includes the right to grant
509patent sublicenses in a manner consistent with the requirements of
510this License.
511
512 Each contributor grants you a non-exclusive, worldwide, royalty-free
513patent license under the contributor's essential patent claims, to
514make, use, sell, offer for sale, import and otherwise run, modify and
515propagate the contents of its contributor version.
516
517 In the following three paragraphs, a "patent license" is any express
518agreement or commitment, however denominated, not to enforce a patent
519(such as an express permission to practice a patent or covenant not to
520sue for patent infringement). To "grant" such a patent license to a
521party means to make such an agreement or commitment not to enforce a
522patent against the party.
523
524 If you convey a covered work, knowingly relying on a patent license,
525and the Corresponding Source of the work is not available for anyone
526to copy, free of charge and under the terms of this License, through a
527publicly available network server or other readily accessible means,
528then you must either (1) cause the Corresponding Source to be so
529available, or (2) arrange to deprive yourself of the benefit of the
530patent license for this particular work, or (3) arrange, in a manner
531consistent with the requirements of this License, to extend the patent
532license to downstream recipients. "Knowingly relying" means you have
533actual knowledge that, but for the patent license, your conveying the
534covered work in a country, or your recipient's use of the covered work
535in a country, would infringe one or more identifiable patents in that
536country that you have reason to believe are valid.
537
538 If, pursuant to or in connection with a single transaction or
539arrangement, you convey, or propagate by procuring conveyance of, a
540covered work, and grant a patent license to some of the parties
541receiving the covered work authorizing them to use, propagate, modify
542or convey a specific copy of the covered work, then the patent license
543you grant is automatically extended to all recipients of the covered
544work and works based on it.
545
546 A patent license is "discriminatory" if it does not include within
547the scope of its coverage, prohibits the exercise of, or is
548conditioned on the non-exercise of one or more of the rights that are
549specifically granted under this License. You may not convey a covered
550work if you are a party to an arrangement with a third party that is
551in the business of distributing software, under which you make payment
552to the third party based on the extent of your activity of conveying
553the work, and under which the third party grants, to any of the
554parties who would receive the covered work from you, a discriminatory
555patent license (a) in connection with copies of the covered work
556conveyed by you (or copies made from those copies), or (b) primarily
557for and in connection with specific products or compilations that
558contain the covered work, unless you entered into that arrangement,
559or that patent license was granted, prior to 28 March 2007.
560
561 Nothing in this License shall be construed as excluding or limiting
562any implied license or other defenses to infringement that may
563otherwise be available to you under applicable patent law.
564
565## 12. No Surrender of Others' Freedom.
566
567 If conditions are imposed on you (whether by court order, agreement or
568otherwise) that contradict the conditions of this License, they do not
569excuse you from the conditions of this License. If you cannot convey a
570covered work so as to satisfy simultaneously your obligations under this
571License and any other pertinent obligations, then as a consequence you may
572not convey it at all. For example, if you agree to terms that obligate you
573to collect a royalty for further conveying from those to whom you convey
574the Program, the only way you could satisfy both those terms and this
575License would be to refrain entirely from conveying the Program.
576
577## 13. Use with the GNU Affero General Public License.
578
579 Notwithstanding any other provision of this License, you have
580permission to link or combine any covered work with a work licensed
581under version 3 of the GNU Affero General Public License into a single
582combined work, and to convey the resulting work. The terms of this
583License will continue to apply to the part which is the covered work,
584but the special requirements of the GNU Affero General Public License,
585section 13, concerning interaction through a network will apply to the
586combination as such.
587
588## 14. Revised Versions of this License.
589
590 The Free Software Foundation may publish revised and/or new versions of
591the GNU General Public License from time to time. Such new versions will
592be similar in spirit to the present version, but may differ in detail to
593address new problems or concerns.
594
595 Each version is given a distinguishing version number. If the
596Program specifies that a certain numbered version of the GNU General
597Public License "or any later version" applies to it, you have the
598option of following the terms and conditions either of that numbered
599version or of any later version published by the Free Software
600Foundation. If the Program does not specify a version number of the
601GNU General Public License, you may choose any version ever published
602by the Free Software Foundation.
603
604 If the Program specifies that a proxy can decide which future
605versions of the GNU General Public License can be used, that proxy's
606public statement of acceptance of a version permanently authorizes you
607to choose that version for the Program.
608
609 Later license versions may give you additional or different
610permissions. However, no additional obligations are imposed on any
611author or copyright holder as a result of your choosing to follow a
612later version.
613
614## 15. Disclaimer of Warranty.
615
616 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
617APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
618HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
619OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
620THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
621PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
622IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
623ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
624
625## 16. Limitation of Liability.
626
627 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
628WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
629THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
630GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
631USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
632DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
633PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
634EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
635SUCH DAMAGES.
636
637## 17. Interpretation of Sections 15 and 16.
638
639 If the disclaimer of warranty and limitation of liability provided
640above cannot be given local legal effect according to their terms,
641reviewing courts shall apply local law that most closely approximates
642an absolute waiver of all civil liability in connection with the
643Program, unless a warranty or assumption of liability accompanies a
644copy of the Program in return for a fee.

650# How to Apply These Terms to Your New Programs
651
652 If you develop a new program, and you want it to be of the greatest
653possible use to the public, the best way to achieve this is to make it
654free software which everyone can redistribute and change under these terms.
655
656 To do so, attach the following notices to the program. It is safest
657to attach them to the start of each source file to most effectively
658state the exclusion of warranty; and each file should have at least
659the "copyright" line and a pointer to where the full notice is found.
660
661 <one line to give the program's name and a brief idea of what it does.>
662 Copyright (C) <year> <name of author>
663
664 This program is free software: you can redistribute it and/or modify
665 it under the terms of the GNU General Public License as published by
666 the Free Software Foundation, either version 3 of the License, or
667 (at your option) any later version.
668
669 This program is distributed in the hope that it will be useful,
670 but WITHOUT ANY WARRANTY; without even the implied warranty of
671 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
672 GNU General Public License for more details.
673
674 You should have received a copy of the GNU General Public License
675 along with this program. If not, see <http://www.gnu.org/licenses/>.
676
677Also add information on how to contact you by electronic and paper mail.
678
679 If the program does terminal interaction, make it output a short
680notice like this when it starts in an interactive mode:
681
682 <program> Copyright (C) <year> <name of author>
683 This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
684 This is free software, and you are welcome to redistribute it
685 under certain conditions; type 'show c' for details.
686
687 The hypothetical commands _'show w'_ and _'show c'_ should show the appropriate
688parts of the General Public License. Of course, your program's commands
689might be different; for a GUI interface, you would use an "about box".
690
691 You should also get your employer (if you work as a programmer) or school,
692if any, to sign a "copyright disclaimer" for the program, if necessary.
693For more information on this, and how to apply and follow the GNU GPL, see
694<http://www.gnu.org/licenses/>.
695
696 The GNU General Public License does not permit incorporating your program
697into proprietary programs. If your program is a subroutine library, you
698may consider it more useful to permit linking proprietary applications with
699the library. If this is what you want to do, use the GNU Lesser General
700Public License instead of this License. But first, please read
701<http://www.gnu.org/philosophy/why-not-lgpl.html>.
