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