16 | GNU GENERAL PUBLIC LICENSE
17 | Version 3, 29 June 2007
18 |
19 | Copyright (C) 2007 Free Software Foundation, Inc.
20 | Everyone is permitted to copy and distribute verbatim copies
21 | of this license document, but changing it is not allowed.
22 |
23 | Preamble
24 |
25 | The GNU General Public License is a free, copyleft license for
26 | software and other kinds of works.
27 |
28 | The licenses for most software and other practical works are designed
29 | to take away your freedom to share and change the works. By contrast,
30 | the GNU General Public License is intended to guarantee your freedom to
31 | share and change all versions of a program--to make sure it remains free
32 | software for all its users. We, the Free Software Foundation, use the
33 | GNU General Public License for most of our software; it applies also to
34 | any other work released this way by its authors. You can apply it to
35 | your programs, too.
36 |
37 | When we speak of free software, we are referring to freedom, not
38 | price. Our General Public Licenses are designed to make sure that you
39 | have the freedom to distribute copies of free software (and charge for
40 | them if you wish), that you receive source code or can get it if you
41 | want it, that you can change the software or use pieces of it in new
42 | free programs, and that you know you can do these things.
43 |
44 | To protect your rights, we need to prevent others from denying you
45 | these rights or asking you to surrender the rights. Therefore, you have
46 | certain responsibilities if you distribute copies of the software, or if
47 | you modify it: responsibilities to respect the freedom of others.
48 |
49 | For example, if you distribute copies of such a program, whether
50 | gratis or for a fee, you must pass on to the recipients the same
51 | freedoms that you received. You must make sure that they, too, receive
52 | or can get the source code. And you must show them these terms so they
53 | know their rights.
54 |
55 | Developers that use the GNU GPL protect your rights with two steps:
56 | (1) assert copyright on the software, and (2) offer you this License
57 | giving you legal permission to copy, distribute and/or modify it.
58 |
59 | For the developers' and authors' protection, the GPL clearly explains
60 | that there is no warranty for this free software. For both users' and
61 | authors' sake, the GPL requires that modified versions be marked as
62 | changed, so that their problems will not be attributed erroneously to
63 | authors of previous versions.
64 |
65 | Some devices are designed to deny users access to install or run
66 | modified versions of the software inside them, although the manufacturer
67 | can do so. This is fundamentally incompatible with the aim of
68 | protecting users' freedom to change the software. The systematic
69 | pattern of such abuse occurs in the area of products for individuals to
70 | use, which is precisely where it is most unacceptable. Therefore, we
71 | have designed this version of the GPL to prohibit the practice for those
72 | products. If such problems arise substantially in other domains, we
73 | stand ready to extend this provision to those domains in future versions
74 | of the GPL, as needed to protect the freedom of users.
75 |
76 | Finally, every program is threatened constantly by software patents.
77 | States should not allow patents to restrict development and use of
78 | software on general-purpose computers, but in those that do, we wish to
79 | avoid the special danger that patents applied to a free program could
80 | make it effectively proprietary. To prevent this, the GPL assures that
81 | patents cannot be used to render the program non-free.
82 |
83 | The precise terms and conditions for copying, distribution and
84 | modification follow.
85 |
86 | TERMS AND CONDITIONS
87 |
88 | 0. Definitions.
89 |
90 | "This License" refers to version 3 of the GNU General Public License.
91 |
92 | "Copyright" also means copyright-like laws that apply to other kinds of
93 | works, such as semiconductor masks.
94 |
95 | "The Program" refers to any copyrightable work licensed under this
96 | License. Each licensee is addressed as "you". "Licensees" and
97 | "recipients" may be individuals or organizations.
98 |
99 | To "modify" a work means to copy from or adapt all or part of the work
100 | in a fashion requiring copyright permission, other than the making of an
101 | exact copy. The resulting work is called a "modified version" of the
102 | earlier work or a work "based on" the earlier work.
103 |
104 | A "covered work" means either the unmodified Program or a work based
105 | on the Program.
106 |
107 | To "propagate" a work means to do anything with it that, without
108 | permission, would make you directly or secondarily liable for
109 | infringement under applicable copyright law, except executing it on a
110 | computer or modifying a private copy. Propagation includes copying,
111 | distribution (with or without modification), making available to the
112 | public, and in some countries other activities as well.
113 |
114 | To "convey" a work means any kind of propagation that enables other
115 | parties to make or receive copies. Mere interaction with a user through
116 | a computer network, with no transfer of a copy, is not conveying.
117 |
118 | An interactive user interface displays "Appropriate Legal Notices"
119 | to the extent that it includes a convenient and prominently visible
120 | feature that (1) displays an appropriate copyright notice, and (2)
121 | tells the user that there is no warranty for the work (except to the
122 | extent that warranties are provided), that licensees may convey the
123 | work under this License, and how to view a copy of this License. If
124 | the interface presents a list of user commands or options, such as a
125 | menu, a prominent item in the list meets this criterion.
126 |
127 | 1. Source Code.
128 |
129 | The "source code" for a work means the preferred form of the work
130 | for making modifications to it. "Object code" means any non-source
131 | form of a work.
132 |
133 | A "Standard Interface" means an interface that either is an official
134 | standard defined by a recognized standards body, or, in the case of
135 | interfaces specified for a particular programming language, one that
136 | is widely used among developers working in that language.
137 |
138 | The "System Libraries" of an executable work include anything, other
139 | than the work as a whole, that (a) is included in the normal form of
140 | packaging a Major Component, but which is not part of that Major
141 | Component, and (b) serves only to enable use of the work with that
142 | Major Component, or to implement a Standard Interface for which an
143 | implementation is available to the public in source code form. A
144 | "Major Component", in this context, means a major essential component
145 | (kernel, window system, and so on) of the specific operating system
146 | (if any) on which the executable work runs, or a compiler used to
147 | produce the work, or an object code interpreter used to run it.
148 |
149 | The "Corresponding Source" for a work in object code form means all
150 | the source code needed to generate, install, and (for an executable
151 | work) run the object code and to modify the work, including scripts to
152 | control those activities. However, it does not include the work's
153 | System Libraries, or general-purpose tools or generally available free
154 | programs which are used unmodified in performing those activities but
155 | which are not part of the work. For example, Corresponding Source
156 | includes interface definition files associated with source files for
157 | the work, and the source code for shared libraries and dynamically
158 | linked subprograms that the work is specifically designed to require,
159 | such as by intimate data communication or control flow between those
160 | subprograms and other parts of the work.
161 |
162 | The Corresponding Source need not include anything that users
163 | can regenerate automatically from other parts of the Corresponding
164 | Source.
165 |
166 | The Corresponding Source for a work in source code form is that
167 | same work.
168 |
169 | 2. Basic Permissions.
170 |
171 | All rights granted under this License are granted for the term of
172 | copyright on the Program, and are irrevocable provided the stated
173 | conditions are met. This License explicitly affirms your unlimited
174 | permission to run the unmodified Program. The output from running a
175 | covered work is covered by this License only if the output, given its
176 | content, constitutes a covered work. This License acknowledges your
177 | rights of fair use or other equivalent, as provided by copyright law.
178 |
179 | You may make, run and propagate covered works that you do not
180 | convey, without conditions so long as your license otherwise remains
181 | in force. You may convey covered works to others for the sole purpose
182 | of having them make modifications exclusively for you, or provide you
183 | with facilities for running those works, provided that you comply with
184 | the terms of this License in conveying all material for which you do
185 | not control copyright. Those thus making or running the covered works
186 | for you must do so exclusively on your behalf, under your direction
187 | and control, on terms that prohibit them from making any copies of
188 | your copyrighted material outside their relationship with you.
189 |
190 | Conveying under any other circumstances is permitted solely under
191 | the conditions stated below. Sublicensing is not allowed; section 10
192 | makes it unnecessary.
193 |
194 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
195 |
196 | No covered work shall be deemed part of an effective technological
197 | measure under any applicable law fulfilling obligations under article
198 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
199 | similar laws prohibiting or restricting circumvention of such
200 | measures.
201 |
202 | When you convey a covered work, you waive any legal power to forbid
203 | circumvention of technological measures to the extent such circumvention
204 | is effected by exercising rights under this License with respect to
205 | the covered work, and you disclaim any intention to limit operation or
206 | modification of the work as a means of enforcing, against the work's
207 | users, your or third parties' legal rights to forbid circumvention of
208 | technological measures.
209 |
210 | 4. Conveying Verbatim Copies.
211 |
212 | You may convey verbatim copies of the Program's source code as you
213 | receive it, in any medium, provided that you conspicuously and
214 | appropriately publish on each copy an appropriate copyright notice;
215 | keep intact all notices stating that this License and any
216 | non-permissive terms added in accord with section 7 apply to the code;
217 | keep intact all notices of the absence of any warranty; and give all
218 | recipients a copy of this License along with the Program.
219 |
220 | You may charge any price or no price for each copy that you convey,
221 | and you may offer support or warranty protection for a fee.
222 |
223 | 5. Conveying Modified Source Versions.
224 |
225 | You may convey a work based on the Program, or the modifications to
226 | produce it from the Program, in the form of source code under the
227 | terms of section 4, provided that you also meet all of these conditions:
228 |
229 | a) The work must carry prominent notices stating that you modified
230 | it, and giving a relevant date.
231 |
232 | b) The work must carry prominent notices stating that it is
233 | released under this License and any conditions added under section
234 | 7. This requirement modifies the requirement in section 4 to
235 | "keep intact all notices".
236 |
237 | c) You must license the entire work, as a whole, under this
238 | License to anyone who comes into possession of a copy. This
239 | License will therefore apply, along with any applicable section 7
240 | additional terms, to the whole of the work, and all its parts,
241 | regardless of how they are packaged. This License gives no
242 | permission to license the work in any other way, but it does not
243 | invalidate such permission if you have separately received it.
244 |
245 | d) If the work has interactive user interfaces, each must display
246 | Appropriate Legal Notices; however, if the Program has interactive
247 | interfaces that do not display Appropriate Legal Notices, your
248 | work need not make them do so.
249 |
250 | A compilation of a covered work with other separate and independent
251 | works, which are not by their nature extensions of the covered work,
252 | and which are not combined with it such as to form a larger program,
253 | in or on a volume of a storage or distribution medium, is called an
254 | "aggregate" if the compilation and its resulting copyright are not
255 | used to limit the access or legal rights of the compilation's users
256 | beyond what the individual works permit. Inclusion of a covered work
257 | in an aggregate does not cause this License to apply to the other
258 | parts of the aggregate.
259 |
260 | 6. Conveying Non-Source Forms.
261 |
262 | You may convey a covered work in object code form under the terms
263 | of sections 4 and 5, provided that you also convey the
264 | machine-readable Corresponding Source under the terms of this License,
265 | in one of these ways:
266 |
267 | a) Convey the object code in, or embodied in, a physical product
268 | (including a physical distribution medium), accompanied by the
269 | Corresponding Source fixed on a durable physical medium
270 | customarily used for software interchange.
271 |
272 | b) Convey the object code in, or embodied in, a physical product
273 | (including a physical distribution medium), accompanied by a
274 | written offer, valid for at least three years and valid for as
275 | long as you offer spare parts or customer support for that product
276 | model, to give anyone who possesses the object code either (1) a
277 | copy of the Corresponding Source for all the software in the
278 | product that is covered by this License, on a durable physical
279 | medium customarily used for software interchange, for a price no
280 | more than your reasonable cost of physically performing this
281 | conveying of source, or (2) access to copy the
282 | Corresponding Source from a network server at no charge.
283 |
284 | c) Convey individual copies of the object code with a copy of the
285 | written offer to provide the Corresponding Source. This
286 | alternative is allowed only occasionally and noncommercially, and
287 | only if you received the object code with such an offer, in accord
288 | with subsection 6b.
289 |
290 | d) Convey the object code by offering access from a designated
291 | place (gratis or for a charge), and offer equivalent access to the
292 | Corresponding Source in the same way through the same place at no
293 | further charge. You need not require recipients to copy the
294 | Corresponding Source along with the object code. If the place to
295 | copy the object code is a network server, the Corresponding Source
296 | may be on a different server (operated by you or a third party)
297 | that supports equivalent copying facilities, provided you maintain
298 | clear directions next to the object code saying where to find the
299 | Corresponding Source. Regardless of what server hosts the
300 | Corresponding Source, you remain obligated to ensure that it is
301 | available for as long as needed to satisfy these requirements.
302 |
303 | e) Convey the object code using peer-to-peer transmission, provided
304 | you inform other peers where the object code and Corresponding
305 | Source of the work are being offered to the general public at no
306 | charge under subsection 6d.
307 |
308 | A separable portion of the object code, whose source code is excluded
309 | from the Corresponding Source as a System Library, need not be
310 | included in conveying the object code work.
311 |
312 | A "User Product" is either (1) a "consumer product", which means any
313 | tangible personal property which is normally used for personal, family,
314 | or household purposes, or (2) anything designed or sold for incorporation
315 | into a dwelling. In determining whether a product is a consumer product,
316 | doubtful cases shall be resolved in favor of coverage. For a particular
317 | product received by a particular user, "normally used" refers to a
318 | typical or common use of that class of product, regardless of the status
319 | of the particular user or of the way in which the particular user
320 | actually uses, or expects or is expected to use, the product. A product
321 | is a consumer product regardless of whether the product has substantial
322 | commercial, industrial or non-consumer uses, unless such uses represent
323 | the only significant mode of use of the product.
324 |
325 | "Installation Information" for a User Product means any methods,
326 | procedures, authorization keys, or other information required to install
327 | and execute modified versions of a covered work in that User Product from
328 | a modified version of its Corresponding Source. The information must
329 | suffice to ensure that the continued functioning of the modified object
330 | code is in no case prevented or interfered with solely because
331 | modification has been made.
332 |
333 | If you convey an object code work under this section in, or with, or
334 | specifically for use in, a User Product, and the conveying occurs as
335 | part of a transaction in which the right of possession and use of the
336 | User Product is transferred to the recipient in perpetuity or for a
337 | fixed term (regardless of how the transaction is characterized), the
338 | Corresponding Source conveyed under this section must be accompanied
339 | by the Installation Information. But this requirement does not apply
340 | if neither you nor any third party retains the ability to install
341 | modified object code on the User Product (for example, the work has
342 | been installed in ROM).
343 |
344 | The requirement to provide Installation Information does not include a
345 | requirement to continue to provide support service, warranty, or updates
346 | for a work that has been modified or installed by the recipient, or for
347 | the User Product in which it has been modified or installed. Access to a
348 | network may be denied when the modification itself materially and
349 | adversely affects the operation of the network or violates the rules and
350 | protocols for communication across the network.
351 |
352 | Corresponding Source conveyed, and Installation Information provided,
353 | in accord with this section must be in a format that is publicly
354 | documented (and with an implementation available to the public in
355 | source code form), and must require no special password or key for
356 | unpacking, reading or copying.
357 |
358 | 7. Additional Terms.
359 |
360 | "Additional permissions" are terms that supplement the terms of this
361 | License by making exceptions from one or more of its conditions.
362 | Additional permissions that are applicable to the entire Program shall
363 | be treated as though they were included in this License, to the extent
364 | that they are valid under applicable law. If additional permissions
365 | apply only to part of the Program, that part may be used separately
366 | under those permissions, but the entire Program remains governed by
367 | this License without regard to the additional permissions.
368 |
369 | When you convey a copy of a covered work, you may at your option
370 | remove any additional permissions from that copy, or from any part of
371 | it. (Additional permissions may be written to require their own
372 | removal in certain cases when you modify the work.) You may place
373 | additional permissions on material, added by you to a covered work,
374 | for which you have or can give appropriate copyright permission.
375 |
376 | Notwithstanding any other provision of this License, for material you
377 | add to a covered work, you may (if authorized by the copyright holders of
378 | that material) supplement the terms of this License with terms:
379 |
380 | a) Disclaiming warranty or limiting liability differently from the
381 | terms of sections 15 and 16 of this License; or
382 |
383 | b) Requiring preservation of specified reasonable legal notices or
384 | author attributions in that material or in the Appropriate Legal
385 | Notices displayed by works containing it; or
386 |
387 | c) Prohibiting misrepresentation of the origin of that material, or
388 | requiring that modified versions of such material be marked in
389 | reasonable ways as different from the original version; or
390 |
391 | d) Limiting the use for publicity purposes of names of licensors or
392 | authors of the material; or
393 |
394 | e) Declining to grant rights under trademark law for use of some
395 | trade names, trademarks, or service marks; or
396 |
397 | f) Requiring indemnification of licensors and authors of that
398 | material by anyone who conveys the material (or modified versions of
399 | it) with contractual assumptions of liability to the recipient, for
400 | any liability that these contractual assumptions directly impose on
401 | those licensors and authors.
402 |
403 | All other non-permissive additional terms are considered "further
404 | restrictions" within the meaning of section 10. If the Program as you
405 | received it, or any part of it, contains a notice stating that it is
406 | governed by this License along with a term that is a further
407 | restriction, you may remove that term. If a license document contains
408 | a further restriction but permits relicensing or conveying under this
409 | License, you may add to a covered work material governed by the terms
410 | of that license document, provided that the further restriction does
411 | not survive such relicensing or conveying.
412 |
413 | If you add terms to a covered work in accord with this section, you
414 | must place, in the relevant source files, a statement of the
415 | additional terms that apply to those files, or a notice indicating
416 | where to find the applicable terms.
417 |
418 | Additional terms, permissive or non-permissive, may be stated in the
419 | form of a separately written license, or stated as exceptions;
420 | the above requirements apply either way.
421 |
422 | 8. Termination.
423 |
424 | You may not propagate or modify a covered work except as expressly
425 | provided under this License. Any attempt otherwise to propagate or
426 | modify it is void, and will automatically terminate your rights under
427 | this License (including any patent licenses granted under the third
428 | paragraph of section 11).
429 |
430 | However, if you cease all violation of this License, then your
431 | license from a particular copyright holder is reinstated (a)
432 | provisionally, unless and until the copyright holder explicitly and
433 | finally terminates your license, and (b) permanently, if the copyright
434 | holder fails to notify you of the violation by some reasonable means
435 | prior to 60 days after the cessation.
436 |
437 | Moreover, your license from a particular copyright holder is
438 | reinstated permanently if the copyright holder notifies you of the
439 | violation by some reasonable means, this is the first time you have
440 | received notice of violation of this License (for any work) from that
441 | copyright holder, and you cure the violation prior to 30 days after
442 | your receipt of the notice.
443 |
444 | Termination of your rights under this section does not terminate the
445 | licenses of parties who have received copies or rights from you under
446 | this License. If your rights have been terminated and not permanently
447 | reinstated, you do not qualify to receive new licenses for the same
448 | material under section 10.
449 |
450 | 9. Acceptance Not Required for Having Copies.
451 |
452 | You are not required to accept this License in order to receive or
453 | run a copy of the Program. Ancillary propagation of a covered work
454 | occurring solely as a consequence of using peer-to-peer transmission
455 | to receive a copy likewise does not require acceptance. However,
456 | nothing other than this License grants you permission to propagate or
457 | modify any covered work. These actions infringe copyright if you do
458 | not accept this License. Therefore, by modifying or propagating a
459 | covered work, you indicate your acceptance of this License to do so.
460 |
461 | 10. Automatic Licensing of Downstream Recipients.
462 |
463 | Each time you convey a covered work, the recipient automatically
464 | receives a license from the original licensors, to run, modify and
465 | propagate that work, subject to this License. You are not responsible
466 | for enforcing compliance by third parties with this License.
467 |
468 | An "entity transaction" is a transaction transferring control of an
469 | organization, or substantially all assets of one, or subdividing an
470 | organization, or merging organizations. If propagation of a covered
471 | work results from an entity transaction, each party to that
472 | transaction who receives a copy of the work also receives whatever
473 | licenses to the work the party's predecessor in interest had or could
474 | give under the previous paragraph, plus a right to possession of the
475 | Corresponding Source of the work from the predecessor in interest, if
476 | the predecessor has it or can get it with reasonable efforts.
477 |
478 | You may not impose any further restrictions on the exercise of the
479 | rights granted or affirmed under this License. For example, you may
480 | not impose a license fee, royalty, or other charge for exercise of
481 | rights granted under this License, and you may not initiate litigation
482 | (including a cross-claim or counterclaim in a lawsuit) alleging that
483 | any patent claim is infringed by making, using, selling, offering for
484 | sale, or importing the Program or any portion of it.
485 |
486 | 11. Patents.
487 |
488 | A "contributor" is a copyright holder who authorizes use under this
489 | License of the Program or a work on which the Program is based. The
490 | work thus licensed is called the contributor's "contributor version".
491 |
492 | A contributor's "essential patent claims" are all patent claims
493 | owned or controlled by the contributor, whether already acquired or
494 | hereafter acquired, that would be infringed by some manner, permitted
495 | by this License, of making, using, or selling its contributor version,
496 | but do not include claims that would be infringed only as a
497 | consequence of further modification of the contributor version. For
498 | purposes of this definition, "control" includes the right to grant
499 | patent sublicenses in a manner consistent with the requirements of
500 | this License.
501 |
502 | Each contributor grants you a non-exclusive, worldwide, royalty-free
503 | patent license under the contributor's essential patent claims, to
504 | make, use, sell, offer for sale, import and otherwise run, modify and
505 | propagate the contents of its contributor version.
506 |
507 | In the following three paragraphs, a "patent license" is any express
508 | agreement or commitment, however denominated, not to enforce a patent
509 | (such as an express permission to practice a patent or covenant not to
510 | sue for patent infringement). To "grant" such a patent license to a
511 | party means to make such an agreement or commitment not to enforce a
512 | patent against the party.
513 |
514 | If you convey a covered work, knowingly relying on a patent license,
515 | and the Corresponding Source of the work is not available for anyone
516 | to copy, free of charge and under the terms of this License, through a
517 | publicly available network server or other readily accessible means,
518 | then you must either (1) cause the Corresponding Source to be so
519 | available, or (2) arrange to deprive yourself of the benefit of the
520 | patent license for this particular work, or (3) arrange, in a manner
521 | consistent with the requirements of this License, to extend the patent
522 | license to downstream recipients. "Knowingly relying" means you have
523 | actual knowledge that, but for the patent license, your conveying the
524 | covered work in a country, or your recipient's use of the covered work
525 | in a country, would infringe one or more identifiable patents in that
526 | country that you have reason to believe are valid.
527 |
528 | If, pursuant to or in connection with a single transaction or
529 | arrangement, you convey, or propagate by procuring conveyance of, a
530 | covered work, and grant a patent license to some of the parties
531 | receiving the covered work authorizing them to use, propagate, modify
532 | or convey a specific copy of the covered work, then the patent license
533 | you grant is automatically extended to all recipients of the covered
534 | work and works based on it.
535 |
536 | A patent license is "discriminatory" if it does not include within
537 | the scope of its coverage, prohibits the exercise of, or is
538 | conditioned on the non-exercise of one or more of the rights that are
539 | specifically granted under this License. You may not convey a covered
540 | work if you are a party to an arrangement with a third party that is
541 | in the business of distributing software, under which you make payment
542 | to the third party based on the extent of your activity of conveying
543 | the work, and under which the third party grants, to any of the
544 | parties who would receive the covered work from you, a discriminatory
545 | patent license (a) in connection with copies of the covered work
546 | conveyed by you (or copies made from those copies), or (b) primarily
547 | for and in connection with specific products or compilations that
548 | contain the covered work, unless you entered into that arrangement,
549 | or that patent license was granted, prior to 28 March 2007.
550 |
551 | Nothing in this License shall be construed as excluding or limiting
552 | any implied license or other defenses to infringement that may
553 | otherwise be available to you under applicable patent law.
554 |
555 | 12. No Surrender of Others' Freedom.
556 |
557 | If conditions are imposed on you (whether by court order, agreement or
558 | otherwise) that contradict the conditions of this License, they do not
559 | excuse you from the conditions of this License. If you cannot convey a
560 | covered work so as to satisfy simultaneously your obligations under this
561 | License and any other pertinent obligations, then as a consequence you may
562 | not convey it at all. For example, if you agree to terms that obligate you
563 | to collect a royalty for further conveying from those to whom you convey
564 | the Program, the only way you could satisfy both those terms and this
565 | License would be to refrain entirely from conveying the Program.
566 |
567 | 13. Use with the GNU Affero General Public License.
568 |
569 | Notwithstanding any other provision of this License, you have
570 | permission to link or combine any covered work with a work licensed
571 | under version 3 of the GNU Affero General Public License into a single
572 | combined work, and to convey the resulting work. The terms of this
573 | License will continue to apply to the part which is the covered work,
574 | but the special requirements of the GNU Affero General Public License,
575 | section 13, concerning interaction through a network will apply to the
576 | combination as such.
577 |
578 | 14. Revised Versions of this License.
579 |
580 | The Free Software Foundation may publish revised and/or new versions of
581 | the GNU General Public License from time to time. Such new versions will
582 | be similar in spirit to the present version, but may differ in detail to
583 | address new problems or concerns.
584 |
585 | Each version is given a distinguishing version number. If the
586 | Program specifies that a certain numbered version of the GNU General
587 | Public License "or any later version" applies to it, you have the
588 | option of following the terms and conditions either of that numbered
589 | version or of any later version published by the Free Software
590 | Foundation. If the Program does not specify a version number of the
591 | GNU General Public License, you may choose any version ever published
592 | by the Free Software Foundation.
593 |
594 | If the Program specifies that a proxy can decide which future
595 | versions of the GNU General Public License can be used, that proxy's
596 | public statement of acceptance of a version permanently authorizes you
597 | to choose that version for the Program.
598 |
599 | Later license versions may give you additional or different
600 | permissions. However, no additional obligations are imposed on any
601 | author or copyright holder as a result of your choosing to follow a
602 | later version.
603 |
604 | 15. Disclaimer of Warranty.
605 |
606 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
607 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
608 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
609 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
610 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
611 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
612 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
613 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
614 |
615 | 16. Limitation of Liability.
616 |
617 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
618 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
619 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
620 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
621 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
622 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
623 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
624 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
625 | SUCH DAMAGES.
626 |
627 | 17. Interpretation of Sections 15 and 16.
628 |
629 | If the disclaimer of warranty and limitation of liability provided
630 | above cannot be given local legal effect according to their terms,
631 | reviewing courts shall apply local law that most closely approximates
632 | an absolute waiver of all civil liability in connection with the
633 | Program, unless a warranty or assumption of liability accompanies a
634 | copy of the Program in return for a fee.
635 |
636 | END OF TERMS AND CONDITIONS
637 |
638 | How to Apply These Terms to Your New Programs
639 |
640 | If you develop a new program, and you want it to be of the greatest
641 | possible use to the public, the best way to achieve this is to make it
642 | free software which everyone can redistribute and change under these terms.
643 |
644 | To do so, attach the following notices to the program. It is safest
645 | to attach them to the start of each source file to most effectively
646 | state the exclusion of warranty; and each file should have at least
647 | the "copyright" line and a pointer to where the full notice is found.
648 |
649 |
650 | Copyright (C)
651 |
652 | This program is free software: you can redistribute it and/or modify
653 | it under the terms of the GNU General Public License as published by
654 | the Free Software Foundation, either version 3 of the License, or
655 | (at your option) any later version.
656 |
657 | This program is distributed in the hope that it will be useful,
658 | but WITHOUT ANY WARRANTY; without even the implied warranty of
659 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
660 | GNU General Public License for more details.
661 |
662 | You should have received a copy of the GNU General Public License
663 | along with this program. If not, see .
664 |
665 | Also add information on how to contact you by electronic and paper mail.
666 |
667 | If the program does terminal interaction, make it output a short
668 | notice like this when it starts in an interactive mode:
669 |
670 | Copyright (C)
671 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
672 | This is free software, and you are welcome to redistribute it
673 | under certain conditions; type `show c' for details.
674 |
675 | The hypothetical commands `show w' and `show c' should show the appropriate
676 | parts of the General Public License. Of course, your program's commands
677 | might be different; for a GUI interface, you would use an "about box".
678 |
679 | You should also get your employer (if you work as a programmer) or school,
680 | if any, to sign a "copyright disclaimer" for the program, if necessary.
681 | For more information on this, and how to apply and follow the GNU GPL, see
682 | .
683 |
684 | The GNU General Public License does not permit incorporating your program
685 | into proprietary programs. If your program is a subroutine library, you
686 | may consider it more useful to permit linking proprietary applications with
687 | the library. If this is what you want to do, use the GNU Lesser General
688 | Public License instead of this License. But first, please read
689 | .
