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