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