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