7 GNU GENERAL PUBLIC LICENSE

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