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 | {project} Copyright (C) {year} {fullname} | |||
|
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 | |||
|
