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