1 | GNU GENERAL PUBLIC LICENSE |
2 | ========================== | |
3 | ||
4 | Version 3, 29 June 2007 | |
5 | ||
6 | Copyright © 2007 Free Software Foundation, Inc. <<http://fsf.org/>> | |
7 | ||
8 | Everyone is permitted to copy and distribute verbatim copies of this license | |
9 | document, but changing it is not allowed. | |
10 | ||
11 | ## Preamble | |
12 | ||
13 | The GNU General Public License is a free, copyleft license for software and other | |
14 | kinds of works. | |
15 | ||
16 | The licenses for most software and other practical works are designed to take away | |
17 | your freedom to share and change the works. By contrast, the GNU General Public | |
18 | License is intended to guarantee your freedom to share and change all versions of a | |
19 | program--to make sure it remains free software for all its users. We, the Free | |
20 | Software Foundation, use the GNU General Public License for most of our software; it | |
21 | applies also to any other work released this way by its authors. You can apply it to | |
22 | your programs, too. | |
23 | ||
24 | When we speak of free software, we are referring to freedom, not price. Our General | |
25 | Public Licenses are designed to make sure that you have the freedom to distribute | |
26 | copies of free software (and charge for them if you wish), that you receive source | |
27 | code or can get it if you want it, that you can change the software or use pieces of | |
28 | it in new free programs, and that you know you can do these things. | |
29 | ||
30 | To protect your rights, we need to prevent others from denying you these rights or | |
31 | asking you to surrender the rights. Therefore, you have certain responsibilities if | |
32 | you distribute copies of the software, or if you modify it: responsibilities to | |
33 | respect the freedom of others. | |
34 | ||
35 | For example, if you distribute copies of such a program, whether gratis or for a fee, | |
36 | you must pass on to the recipients the same freedoms that you received. You must make | |
37 | sure that they, too, receive or can get the source code. And you must show them these | |
38 | 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 permission | |
42 | to copy, distribute and/or modify it. | |
43 | ||
44 | For the developers' and authors' protection, the GPL clearly explains that there is | |
45 | no warranty for this free software. For both users' and authors' sake, the GPL | |
46 | requires that modified versions be marked as changed, so that their problems will not | |
47 | be attributed erroneously to authors of previous versions. | |
48 | ||
49 | Some devices are designed to deny users access to install or run modified versions of | |
50 | the software inside them, although the manufacturer can do so. This is fundamentally | |
51 | incompatible with the aim of protecting users' freedom to change the software. The | |
52 | systematic pattern of such abuse occurs in the area of products for individuals to | |
53 | use, which is precisely where it is most unacceptable. Therefore, we have designed | |
54 | this version of the GPL to prohibit the practice for those products. If such problems | |
55 | arise substantially in other domains, we stand ready to extend this provision to | |
56 | those domains in future versions of the GPL, as needed to protect the freedom of | |
57 | users. | |
58 | ||
59 | Finally, every program is threatened constantly by software patents. States should | |
60 | 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 patents | |
62 | applied to a free program could make it effectively proprietary. To prevent this, the | |
63 | GPL assures that patents cannot be used to render the program non-free. | |
64 | ||
65 | The precise terms and conditions for copying, distribution and modification follow. | |
66 | ||
67 | ## TERMS AND CONDITIONS | |
68 | ||
69 | ### 0. Definitions. | |
70 | ||
71 | “This License” refers to version 3 of the GNU General Public License. | |
72 | ||
73 | “Copyright” also means copyright-like laws that apply to other kinds of | |
74 | works, such as semiconductor masks. | |
75 | ||
76 | “The Program” refers to any copyrightable work licensed under this | |
77 | License. Each licensee is addressed as “you”. “Licensees” and | |
78 | “recipients” may be individuals or organizations. | |
79 | ||
80 | To “modify” a work means to copy from or adapt all or part of the work in | |
81 | a fashion requiring copyright permission, other than the making of an exact copy. The | |
82 | resulting work is called a “modified version” of the earlier work or a | |
83 | work “based on” the earlier work. | |
84 | ||
85 | A “covered work” means either the unmodified Program or a work based on | |
86 | the Program. | |
87 | ||
88 | To “propagate” a work means to do anything with it that, without | |
89 | permission, would make you directly or secondarily liable for infringement under | |
90 | applicable copyright law, except executing it on a computer or modifying a private | |
91 | copy. Propagation includes copying, distribution (with or without modification), | |
92 | making available to the public, and in some countries other activities as well. | |
93 | ||
94 | To “convey” a work means any kind of propagation that enables other | |
95 | parties to make or receive copies. Mere interaction with a user through a computer | |
96 | network, with no transfer of a copy, is not conveying. | |
97 | ||
98 | An interactive user interface displays “Appropriate Legal Notices” to the | |
99 | extent that it includes a convenient and prominently visible feature that (1) | |
100 | displays an appropriate copyright notice, and (2) tells the user that there is no | |
101 | warranty for the work (except to the extent that warranties are provided), that | |
102 | licensees may convey the work under this License, and how to view a copy of this | |
103 | License. If the interface presents a list of user commands or options, such as a | |
104 | menu, a prominent item in the list meets this criterion. | |
105 | ||
106 | ### 1. Source Code. | |
107 | ||
108 | The “source code” for a work means the preferred form of the work for | |
109 | making modifications to it. “Object code” means any non-source form of a | |
110 | work. | |
111 | ||
112 | A “Standard Interface” means an interface that either is an official | |
113 | standard defined by a recognized standards body, or, in the case of interfaces | |
114 | specified for a particular programming language, one that is widely used among | |
115 | developers working in that language. | |
116 | ||
117 | The “System Libraries” of an executable work include anything, other than | |
118 | the work as a whole, that (a) is included in the normal form of packaging a Major | |
119 | Component, but which is not part of that Major Component, and (b) serves only to | |
120 | enable use of the work with that Major Component, or to implement a Standard | |
121 | Interface for which an implementation is available to the public in source code form. | |
122 | A “Major Component”, in this context, means a major essential component | |
123 | (kernel, window system, and so on) of the specific operating system (if any) on which | |
124 | the executable work runs, or a compiler used to produce the work, or an object code | |
125 | interpreter used to run it. | |
126 | ||
127 | The “Corresponding Source” for a work in object code form means all the | |
128 | source code needed to generate, install, and (for an executable work) run the object | |
129 | code and to modify the work, including scripts to control those activities. However, | |
130 | it does not include the work's System Libraries, or general-purpose tools or | |
131 | generally available free programs which are used unmodified in performing those | |
132 | activities but which are not part of the work. For example, Corresponding Source | |
133 | includes interface definition files associated with source files for the work, and | |
134 | the source code for shared libraries and dynamically linked subprograms that the work | |
135 | is specifically designed to require, such as by intimate data communication or | |
136 | control flow between those subprograms and other parts of the work. | |
137 | ||
138 | The Corresponding Source need not include anything that users can regenerate | |
139 | automatically from other parts of the Corresponding Source. | |
140 | ||
141 | The Corresponding Source for a work in source code form is that same work. | |
142 | ||
143 | ### 2. Basic Permissions. | |
144 | ||
145 | All rights granted under this License are granted for the term of copyright on the | |
146 | Program, and are irrevocable provided the stated conditions are met. This License | |
147 | explicitly affirms your unlimited permission to run the unmodified Program. The | |
148 | output from running a covered work is covered by this License only if the output, | |
149 | given its content, constitutes a covered work. This License acknowledges your rights | |
150 | of fair use or other equivalent, as provided by copyright law. | |
151 | ||
152 | You may make, run and propagate covered works that you do not convey, without | |
153 | conditions so long as your license otherwise remains in force. You may convey covered | |
154 | works to others for the sole purpose of having them make modifications exclusively | |
155 | for you, or provide you with facilities for running those works, provided that you | |
156 | comply with the terms of this License in conveying all material for which you do not | |
157 | control copyright. Those thus making or running the covered works for you must do so | |
158 | exclusively on your behalf, under your direction and control, on terms that prohibit | |
159 | them from making any copies of your copyrighted material outside their relationship | |
160 | with you. | |
161 | ||
162 | Conveying under any other circumstances is permitted solely under the conditions | |
163 | stated below. Sublicensing is not allowed; section 10 makes it unnecessary. | |
164 | ||
165 | ### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. | |
166 | ||
167 | No covered work shall be deemed part of an effective technological measure under any | |
168 | applicable law fulfilling obligations under article 11 of the WIPO copyright treaty | |
169 | adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention | |
170 | of such measures. | |
171 | ||
172 | When you convey a covered work, you waive any legal power to forbid circumvention of | |
173 | technological measures to the extent such circumvention is effected by exercising | |
174 | rights under this License with respect to the covered work, and you disclaim any | |
175 | intention to limit operation or modification of the work as a means of enforcing, | |
176 | against the work's users, your or third parties' legal rights to forbid circumvention | |
177 | of technological measures. | |
178 | ||
179 | ### 4. Conveying Verbatim Copies. | |
180 | ||
181 | You may convey verbatim copies of the Program's source code as you receive it, in any | |
182 | medium, provided that you conspicuously and appropriately publish on each copy an | |
183 | appropriate copyright notice; keep intact all notices stating that this License and | |
184 | any non-permissive terms added in accord with section 7 apply to the code; keep | |
185 | intact all notices of the absence of any warranty; and give all recipients a copy of | |
186 | this License along with the Program. | |
187 | ||
188 | You may charge any price or no price for each copy that you convey, and you may offer | |
189 | support or warranty protection for a fee. | |
190 | ||
191 | ### 5. Conveying Modified Source Versions. | |
192 | ||
193 | You may convey a work based on the Program, or the modifications to produce it from | |
194 | the Program, in the form of source code under the terms of section 4, provided that | |
195 | you also meet all of these conditions: | |
196 | ||
197 | * a) The work must carry prominent notices stating that you modified it, and giving a | |
198 | relevant date. | |
199 | * b) The work must carry prominent notices stating that it is released under this | |
200 | License and any conditions added under section 7. This requirement modifies the | |
201 | requirement in section 4 to “keep intact all notices”. | |
202 | * c) You must license the entire work, as a whole, under this License to anyone who | |
203 | comes into possession of a copy. This License will therefore apply, along with any | |
204 | applicable section 7 additional terms, to the whole of the work, and all its parts, | |
205 | regardless of how they are packaged. This License gives no permission to license the | |
206 | work in any other way, but it does not invalidate such permission if you have | |
207 | separately received it. | |
208 | * d) If the work has interactive user interfaces, each must display Appropriate Legal | |
209 | Notices; however, if the Program has interactive interfaces that do not display | |
210 | Appropriate Legal Notices, your work need not make them do so. | |
211 | ||
212 | A compilation of a covered work with other separate and independent works, which are | |
213 | not by their nature extensions of the covered work, and which are not combined with | |
214 | it such as to form a larger program, in or on a volume of a storage or distribution | |
215 | medium, is called an “aggregate” if the compilation and its resulting | |
216 | copyright are not used to limit the access or legal rights of the compilation's users | |
217 | beyond what the individual works permit. Inclusion of a covered work in an aggregate | |
218 | does not cause this License to apply to the other parts of the aggregate. | |
219 | ||
220 | ### 6. Conveying Non-Source Forms. | |
221 | ||
222 | You may convey a covered work in object code form under the terms of sections 4 and | |
223 | 5, provided that you also convey the machine-readable Corresponding Source under the | |
224 | terms of this License, in one of these ways: | |
225 | ||
226 | * a) Convey the object code in, or embodied in, a physical product (including a | |
227 | physical distribution medium), accompanied by the Corresponding Source fixed on a | |
228 | durable physical medium customarily used for software interchange. | |
229 | * b) Convey the object code in, or embodied in, a physical product (including a | |
230 | physical distribution medium), accompanied by a written offer, valid for at least | |
231 | three years and valid for as long as you offer spare parts or customer support for | |
232 | that product model, to give anyone who possesses the object code either (1) a copy of | |
233 | the Corresponding Source for all the software in the product that is covered by this | |
234 | License, on a durable physical medium customarily used for software interchange, for | |
235 | a price no more than your reasonable cost of physically performing this conveying of | |
236 | source, or (2) access to copy the Corresponding Source from a network server at no | |
237 | charge. | |
238 | * c) Convey individual copies of the object code with a copy of the written offer to | |
239 | provide the Corresponding Source. This alternative is allowed only occasionally and | |
240 | noncommercially, and only if you received the object code with such an offer, in | |
241 | accord with subsection 6b. | |
242 | * d) Convey the object code by offering access from a designated place (gratis or for | |
243 | a charge), and offer equivalent access to the Corresponding Source in the same way | |
244 | through the same place at no further charge. You need not require recipients to copy | |
245 | the Corresponding Source along with the object code. If the place to copy the object | |
246 | code is a network server, the Corresponding Source may be on a different server | |
247 | (operated by you or a third party) that supports equivalent copying facilities, | |
248 | provided you maintain clear directions next to the object code saying where to find | |
249 | the Corresponding Source. Regardless of what server hosts the Corresponding Source, | |
250 | you remain obligated to ensure that it is available for as long as needed to satisfy | |
251 | these requirements. | |
252 | * e) Convey the object code using peer-to-peer transmission, provided you inform | |
253 | other peers where the object code and Corresponding Source of the work are being | |
254 | offered to the general public at no charge under subsection 6d. | |
255 | ||
256 | A separable portion of the object code, whose source code is excluded from the | |
257 | Corresponding Source as a System Library, need not be included in conveying the | |
258 | object code work. | |
259 | ||
260 | A “User Product” is either (1) a “consumer product”, which | |
261 | means any tangible personal property which is normally used for personal, family, or | |
262 | household purposes, or (2) anything designed or sold for incorporation into a | |
263 | dwelling. In determining whether a product is a consumer product, doubtful cases | |
264 | shall be resolved in favor of coverage. For a particular product received by a | |
265 | particular user, “normally used” refers to a typical or common use of | |
266 | that class of product, regardless of the status of the particular user or of the way | |
267 | in which the particular user actually uses, or expects or is expected to use, the | |
268 | product. A product is a consumer product regardless of whether the product has | |
269 | substantial commercial, industrial or non-consumer uses, unless such uses represent | |
270 | the only significant mode of use of the product. | |
271 | ||
272 | “Installation Information” for a User Product means any methods, | |
273 | procedures, authorization keys, or other information required to install and execute | |
274 | modified versions of a covered work in that User Product from a modified version of | |
275 | its Corresponding Source. The information must suffice to ensure that the continued | |
276 | functioning of the modified object code is in no case prevented or interfered with | |
277 | solely because modification has been made. | |
278 | ||
279 | If you convey an object code work under this section in, or with, or specifically for | |
280 | use in, a User Product, and the conveying occurs as part of a transaction in which | |
281 | the right of possession and use of the User Product is transferred to the recipient | |
282 | in perpetuity or for a fixed term (regardless of how the transaction is | |
283 | characterized), the Corresponding Source conveyed under this section must be | |
284 | accompanied by the Installation Information. But this requirement does not apply if | |
285 | neither you nor any third party retains the ability to install modified object code | |
286 | on the User Product (for example, the work has been installed in ROM). | |
287 | ||
288 | The requirement to provide Installation Information does not include a requirement to | |
289 | continue to provide support service, warranty, or updates for a work that has been | |
290 | modified or installed by the recipient, or for the User Product in which it has been | |
291 | modified or installed. Access to a network may be denied when the modification itself | |
292 | materially and adversely affects the operation of the network or violates the rules | |
293 | and protocols for communication across the network. | |
294 | ||
295 | Corresponding Source conveyed, and Installation Information provided, in accord with | |
296 | this section must be in a format that is publicly documented (and with an | |
297 | implementation available to the public in source code form), and must require no | |
298 | special password or key for unpacking, reading or copying. | |
299 | ||
300 | ### 7. Additional Terms. | |
301 | ||
302 | “Additional permissions” are terms that supplement the terms of this | |
303 | License by making exceptions from one or more of its conditions. Additional | |
304 | permissions that are applicable to the entire Program shall be treated as though they | |
305 | were included in this License, to the extent that they are valid under applicable | |
306 | law. If additional permissions apply only to part of the Program, that part may be | |
307 | used separately under those permissions, but the entire Program remains governed by | |
308 | this License without regard to the additional permissions. | |
309 | ||
310 | When you convey a copy of a covered work, you may at your option remove any | |
311 | additional permissions from that copy, or from any part of it. (Additional | |
312 | permissions may be written to require their own removal in certain cases when you | |
313 | modify the work.) You may place additional permissions on material, added by you to a | |
314 | covered work, for which you have or can give appropriate copyright permission. | |
315 | ||
316 | Notwithstanding any other provision of this License, for material you add to a | |
317 | covered work, you may (if authorized by the copyright holders of that material) | |
318 | supplement the terms of this License with terms: | |
319 | ||
320 | * a) Disclaiming warranty or limiting liability differently from the terms of | |
321 | sections 15 and 16 of this License; or | |
322 | * b) Requiring preservation of specified reasonable legal notices or author | |
323 | attributions in that material or in the Appropriate Legal Notices displayed by works | |
324 | containing it; or | |
325 | * c) Prohibiting misrepresentation of the origin of that material, or requiring that | |
326 | modified versions of such material be marked in reasonable ways as different from the | |
327 | original version; or | |
328 | * d) Limiting the use for publicity purposes of names of licensors or authors of the | |
329 | material; or | |
330 | * e) Declining to grant rights under trademark law for use of some trade names, | |
331 | trademarks, or service marks; or | |
332 | * f) Requiring indemnification of licensors and authors of that material by anyone | |
333 | who conveys the material (or modified versions of it) with contractual assumptions of | |
334 | liability to the recipient, for any liability that these contractual assumptions | |
335 | directly impose on those licensors and authors. | |
336 | ||
337 | All other non-permissive additional terms are considered “further | |
338 | restrictions” within the meaning of section 10. If the Program as you received | |
339 | it, or any part of it, contains a notice stating that it is governed by this License | |
340 | along with a term that is a further restriction, you may remove that term. If a | |
341 | license document contains a further restriction but permits relicensing or conveying | |
342 | under this License, you may add to a covered work material governed by the terms of | |
343 | that license document, provided that the further restriction does not survive such | |
344 | relicensing or conveying. | |
345 | ||
346 | If you add terms to a covered work in accord with this section, you must place, in | |
347 | the relevant source files, a statement of the additional terms that apply to those | |
348 | files, or a notice indicating where to find the applicable terms. | |
349 | ||
350 | Additional terms, permissive or non-permissive, may be stated in the form of a | |
351 | separately written license, or stated as exceptions; the above requirements apply | |
352 | either way. | |
353 | ||
354 | ### 8. Termination. | |
355 | ||
356 | You may not propagate or modify a covered work except as expressly provided under | |
357 | this License. Any attempt otherwise to propagate or modify it is void, and will | |
358 | automatically terminate your rights under this License (including any patent licenses | |
359 | granted under the third paragraph of section 11). | |
360 | ||
361 | However, if you cease all violation of this License, then your license from a | |
362 | particular copyright holder is reinstated (a) provisionally, unless and until the | |
363 | copyright holder explicitly and finally terminates your license, and (b) permanently, | |
364 | if the copyright holder fails to notify you of the violation by some reasonable means | |
365 | prior to 60 days after the cessation. | |
366 | ||
367 | Moreover, your license from a particular copyright holder is reinstated permanently | |
368 | if the copyright holder notifies you of the violation by some reasonable means, this | |
369 | is the first time you have received notice of violation of this License (for any | |
370 | work) from that copyright holder, and you cure the violation prior to 30 days after | |
371 | your receipt of the notice. | |
372 | ||
373 | Termination of your rights under this section does not terminate the licenses of | |
374 | parties who have received copies or rights from you under this License. If your | |
375 | rights have been terminated and not permanently reinstated, you do not qualify to | |
376 | receive new licenses for the same material under section 10. | |
377 | ||
378 | ### 9. Acceptance Not Required for Having Copies. | |
379 | ||
380 | You are not required to accept this License in order to receive or run a copy of the | |
381 | Program. Ancillary propagation of a covered work occurring solely as a consequence of | |
382 | using peer-to-peer transmission to receive a copy likewise does not require | |
383 | acceptance. However, nothing other than this License grants you permission to | |
384 | propagate or modify any covered work. These actions infringe copyright if you do not | |
385 | accept this License. Therefore, by modifying or propagating a covered work, you | |
386 | indicate your acceptance of this License to do so. | |
387 | ||
388 | ### 10. Automatic Licensing of Downstream Recipients. | |
389 | ||
390 | Each time you convey a covered work, the recipient automatically receives a license | |
391 | from the original licensors, to run, modify and propagate that work, subject to this | |
392 | License. You are not responsible for enforcing compliance by third parties with this | |
393 | License. | |
394 | ||
395 | An “entity transaction” is a transaction transferring control of an | |
396 | organization, or substantially all assets of one, or subdividing an organization, or | |
397 | merging organizations. If propagation of a covered work results from an entity | |
398 | transaction, each party to that transaction who receives a copy of the work also | |
399 | receives whatever licenses to the work the party's predecessor in interest had or | |
400 | could give under the previous paragraph, plus a right to possession of the | |
401 | Corresponding Source of the work from the predecessor in interest, if the predecessor | |
402 | has it or can get it with reasonable efforts. | |
403 | ||
404 | You may not impose any further restrictions on the exercise of the rights granted or | |
405 | affirmed under this License. For example, you may not impose a license fee, royalty, | |
406 | or other charge for exercise of rights granted under this License, and you may not | |
407 | initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging | |
408 | that any patent claim is infringed by making, using, selling, offering for sale, or | |
409 | importing the Program or any portion of it. | |
410 | ||
411 | ### 11. Patents. | |

413 | A “contributor” is a copyright holder who authorizes use under this | |
414 | License of the Program or a work on which the Program is based. The work thus | |
415 | licensed is called the contributor's “contributor version”. | |
416 | ||
417 | A contributor's “essential patent claims” are all patent claims owned or | |
418 | controlled by the contributor, whether already acquired or hereafter acquired, that | |
419 | would be infringed by some manner, permitted by this License, of making, using, or | |
420 | selling its contributor version, but do not include claims that would be infringed | |
421 | only as a consequence of further modification of the contributor version. For | |
422 | purposes of this definition, “control” includes the right to grant patent | |
423 | sublicenses in a manner consistent with the requirements of this License. | |
424 | ||
425 | Each contributor grants you a non-exclusive, worldwide, royalty-free patent license | |
426 | under the contributor's essential patent claims, to make, use, sell, offer for sale, | |
427 | import and otherwise run, modify and propagate the contents of its contributor | |
428 | version. | |
429 | ||
430 | In the following three paragraphs, a “patent license” is any express | |
431 | agreement or commitment, however denominated, not to enforce a patent (such as an | |
432 | express permission to practice a patent or covenant not to sue for patent | |
433 | infringement). To “grant” such a patent license to a party means to make | |
434 | such an agreement or commitment not to enforce a patent against the party. | |
435 | ||
436 | If you convey a covered work, knowingly relying on a patent license, and the | |
437 | Corresponding Source of the work is not available for anyone to copy, free of charge | |
438 | and under the terms of this License, through a publicly available network server or | |
439 | other readily accessible means, then you must either (1) cause the Corresponding | |
440 | Source to be so available, or (2) arrange to deprive yourself of the benefit of the | |
441 | patent license for this particular work, or (3) arrange, in a manner consistent with | |
442 | the requirements of this License, to extend the patent license to downstream | |
443 | recipients. “Knowingly relying” means you have actual knowledge that, but | |
444 | for the patent license, your conveying the covered work in a country, or your | |
445 | recipient's use of the covered work in a country, would infringe one or more | |
446 | identifiable patents in that country that you have reason to believe are valid. | |
447 | ||
448 | If, pursuant to or in connection with a single transaction or arrangement, you | |
449 | convey, or propagate by procuring conveyance of, a covered work, and grant a patent | |
450 | license to some of the parties receiving the covered work authorizing them to use, | |
451 | propagate, modify or convey a specific copy of the covered work, then the patent | |
452 | license you grant is automatically extended to all recipients of the covered work and | |
453 | works based on it. | |
454 | ||
455 | A patent license is “discriminatory” if it does not include within the | |
456 | scope of its coverage, prohibits the exercise of, or is conditioned on the | |
457 | non-exercise of one or more of the rights that are specifically granted under this | |
458 | License. You may not convey a covered work if you are a party to an arrangement with | |
459 | a third party that is in the business of distributing software, under which you make | |
460 | payment to the third party based on the extent of your activity of conveying the | |
461 | work, and under which the third party grants, to any of the parties who would receive | |
462 | the covered work from you, a discriminatory patent license (a) in connection with | |
463 | copies of the covered work conveyed by you (or copies made from those copies), or (b) | |
464 | primarily for and in connection with specific products or compilations that contain | |
465 | the covered work, unless you entered into that arrangement, or that patent license | |
466 | was granted, prior to 28 March 2007. | |
467 | ||
468 | Nothing in this License shall be construed as excluding or limiting any implied | |
469 | license or other defenses to infringement that may otherwise be available to you | |
470 | under applicable patent law. | |
471 | ||
472 | ### 12. No Surrender of Others' Freedom. | |
473 | ||
474 | If conditions are imposed on you (whether by court order, agreement or otherwise) | |
475 | that contradict the conditions of this License, they do not excuse you from the | |
476 | conditions of this License. If you cannot convey a covered work so as to satisfy | |
477 | simultaneously your obligations under this License and any other pertinent | |
478 | obligations, then as a consequence you may not convey it at all. For example, if you | |
479 | agree to terms that obligate you to collect a royalty for further conveying from | |
480 | those to whom you convey the Program, the only way you could satisfy both those terms | |
481 | and this License would be to refrain entirely from conveying the Program. | |
482 | ||
483 | ### 13. Use with the GNU Affero General Public License. | |
484 | ||
485 | Notwithstanding any other provision of this License, you have permission to link or | |
486 | combine any covered work with a work licensed under version 3 of the GNU Affero | |
487 | General Public License into a single combined work, and to convey the resulting work. | |
488 | The terms of this License will continue to apply to the part which is the covered | |
489 | work, but the special requirements of the GNU Affero General Public License, section | |
490 | 13, concerning interaction through a network will apply to the combination as such. | |
491 | ||
492 | ### 14. Revised Versions of this License. | |
493 | ||
494 | The Free Software Foundation may publish revised and/or new versions of the GNU | |
495 | General Public License from time to time. Such new versions will be similar in spirit | |
496 | to the present version, but may differ in detail to address new problems or concerns. | |
497 | ||
498 | Each version is given a distinguishing version number. If the Program specifies that | |
499 | a certain numbered version of the GNU General Public License “or any later | |
500 | version” applies to it, you have the option of following the terms and | |
501 | conditions either of that numbered version or of any later version published by the | |
502 | Free Software Foundation. If the Program does not specify a version number of the GNU | |
503 | General Public License, you may choose any version ever published by the Free | |
504 | Software Foundation. | |
505 | ||
506 | If the Program specifies that a proxy can decide which future versions of the GNU | |
507 | General Public License can be used, that proxy's public statement of acceptance of a | |
508 | version permanently authorizes you to choose that version for the Program. | |
509 | ||
510 | Later license versions may give you additional or different permissions. However, no | |
511 | additional obligations are imposed on any author or copyright holder as a result of | |
512 | your choosing to follow a later version. | |
513 | ||
514 | ### 15. Disclaimer of Warranty. | |
515 | ||
516 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. | |
517 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
518 | PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER | |
519 | EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
520 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE | |
521 | QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE | |
522 | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
523 | ||
524 | ### 16. Limitation of Liability. | |
525 | ||
526 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY | |
527 | COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS | |
528 | PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, | |
529 | INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE | |
530 | PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE | |
531 | OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE | |
532 | WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
533 | POSSIBILITY OF SUCH DAMAGES. | |
534 | ||
535 | ### 17. Interpretation of Sections 15 and 16. | |
536 | ||
537 | If the disclaimer of warranty and limitation of liability provided above cannot be | |
538 | given local legal effect according to their terms, reviewing courts shall apply local | |
539 | law that most closely approximates an absolute waiver of all civil liability in | |
540 | connection with the Program, unless a warranty or assumption of liability accompanies | |
541 | a copy of the Program in return for a fee. |
