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>. |
