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