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