|
|
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 |

|

640 (at your option) any later version. |

|
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. |
|

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 |
