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