13 | <p style="text-align: center;">Version 3, 29 June 2007</p> | |
14 | ||
15 | <p>Copyright © 2007 Free Software Foundation, Inc. | |
16 | <<a href="https://fsf.org/">https://fsf.org/</a>></p><p> | |
17 | Everyone is permitted to copy and distribute verbatim copies | |
18 | of this license document, but changing it is not allowed.</p> | |
19 | ||
20 | <h3><a name="preamble"></a>Preamble</h3> | |
21 | ||
22 | <p>The GNU General Public License is a free, copyleft license for | |
23 | software and other kinds of works.</p> | |
24 | ||
25 | <p>The licenses for most software and other practical works are designed | |
26 | to take away your freedom to share and change the works. By contrast, | |
27 | the GNU General Public License is intended to guarantee your freedom to | |
28 | share and change all versions of a program--to make sure it remains free | |
29 | software for all its users. We, the Free Software Foundation, use the | |
30 | GNU General Public License for most of our software; it applies also to | |
31 | any other work released this way by its authors. You can apply it to | |
32 | your programs, too.</p> | |
33 | ||
34 | <p>When we speak of free software, we are referring to freedom, not | |
35 | price. Our General Public Licenses are designed to make sure that you | |
36 | have the freedom to distribute copies of free software (and charge for | |
37 | them if you wish), that you receive source code or can get it if you | |
38 | want it, that you can change the software or use pieces of it in new | |
39 | free programs, and that you know you can do these things.</p> | |
40 | ||
41 | <p>To protect your rights, we need to prevent others from denying you | |
42 | these rights or asking you to surrender the rights. Therefore, you have | |
43 | certain responsibilities if you distribute copies of the software, or if | |
44 | you modify it: responsibilities to respect the freedom of others.</p> | |
45 | ||
46 | <p>For example, if you distribute copies of such a program, whether | |
47 | gratis or for a fee, you must pass on to the recipients the same | |
48 | freedoms that you received. You must make sure that they, too, receive | |
49 | or can get the source code. And you must show them these terms so they | |
50 | know their rights.</p> | |
51 | ||
52 | <p>Developers that use the GNU GPL protect your rights with two steps: | |
53 | (1) assert copyright on the software, and (2) offer you this License | |
54 | giving you legal permission to copy, distribute and/or modify it.</p> | |
55 | ||
56 | <p>For the developers' and authors' protection, the GPL clearly explains | |
57 | that there is no warranty for this free software. For both users' and | |
58 | authors' sake, the GPL requires that modified versions be marked as | |
59 | changed, so that their problems will not be attributed erroneously to | |
60 | authors of previous versions.</p> | |
61 | ||
62 | <p>Some devices are designed to deny users access to install or run | |
63 | modified versions of the software inside them, although the manufacturer | |
64 | can do so. This is fundamentally incompatible with the aim of | |
65 | protecting users' freedom to change the software. The systematic | |
66 | pattern of such abuse occurs in the area of products for individuals to | |
67 | use, which is precisely where it is most unacceptable. Therefore, we | |
68 | have designed this version of the GPL to prohibit the practice for those | |
69 | products. If such problems arise substantially in other domains, we | |
70 | stand ready to extend this provision to those domains in future versions | |
71 | of the GPL, as needed to protect the freedom of users.</p> | |
72 | ||
73 | <p>Finally, every program is threatened constantly by software patents. | |
74 | States should not allow patents to restrict development and use of | |
75 | software on general-purpose computers, but in those that do, we wish to | |
76 | avoid the special danger that patents applied to a free program could | |
77 | make it effectively proprietary. To prevent this, the GPL assures that | |
78 | patents cannot be used to render the program non-free.</p> | |
79 | ||
80 | <p>The precise terms and conditions for copying, distribution and | |
81 | modification follow.</p> | |
82 | ||
83 | <h3><a name="terms"></a>TERMS AND CONDITIONS</h3> | |
84 | ||
85 | <h4><a name="section0"></a>0. Definitions.</h4> | |
86 | ||
87 | <p>“This License” refers to version 3 of the GNU General Public License.</p> | |
88 | ||
89 | <p>“Copyright” also means copyright-like laws that apply to other kinds of | |
90 | works, such as semiconductor masks.</p> | |
91 | ||
92 | <p>“The Program” refers to any copyrightable work licensed under this | |
93 | License. Each licensee is addressed as “you”. “Licensees” and | |
94 | “recipients” may be individuals or organizations.</p> | |
95 | ||
96 | <p>To “modify” a work means to copy from or adapt all or part of the work | |
97 | in a fashion requiring copyright permission, other than the making of an | |
98 | exact copy. The resulting work is called a “modified version” of the | |
99 | earlier work or a work “based on” the earlier work.</p> | |
100 | ||
101 | <p>A “covered work” means either the unmodified Program or a work based | |
102 | on the Program.</p> | |
103 | ||
104 | <p>To “propagate” a work means to do anything with it that, without | |
105 | permission, would make you directly or secondarily liable for | |
106 | infringement under applicable copyright law, except executing it on a | |
107 | computer or modifying a private copy. Propagation includes copying, | |
108 | distribution (with or without modification), making available to the | |
109 | public, and in some countries other activities as well.</p> | |
110 | ||
111 | <p>To “convey” a work means any kind of propagation that enables other | |
112 | parties to make or receive copies. Mere interaction with a user through | |
113 | a computer network, with no transfer of a copy, is not conveying.</p> | |
114 | ||
115 | <p>An interactive user interface displays “Appropriate Legal Notices” | |
116 | to the extent that it includes a convenient and prominently visible | |
117 | feature that (1) displays an appropriate copyright notice, and (2) | |
118 | tells the user that there is no warranty for the work (except to the | |
119 | extent that warranties are provided), that licensees may convey the | |
120 | work under this License, and how to view a copy of this License. If | |
121 | the interface presents a list of user commands or options, such as a | |
122 | menu, a prominent item in the list meets this criterion.</p> | |
123 | ||
124 | <h4><a name="section1"></a>1. Source Code.</h4> | |
125 | ||
126 | <p>The “source code” for a work means the preferred form of the work | |
127 | for making modifications to it. “Object code” means any non-source | |
128 | form of a work.</p> | |
129 | ||
130 | <p>A “Standard Interface” means an interface that either is an official | |
131 | standard defined by a recognized standards body, or, in the case of | |
132 | interfaces specified for a particular programming language, one that | |
133 | is widely used among developers working in that language.</p> | |
134 | ||
135 | <p>The “System Libraries” of an executable work include anything, other | |
136 | than the work as a whole, that (a) is included in the normal form of | |
137 | packaging a Major Component, but which is not part of that Major | |
138 | Component, and (b) serves only to enable use of the work with that | |
139 | Major Component, or to implement a Standard Interface for which an | |
140 | implementation is available to the public in source code form. A | |
141 | “Major Component”, in this context, means a major essential component | |
142 | (kernel, window system, and so on) of the specific operating system | |
143 | (if any) on which the executable work runs, or a compiler used to | |
144 | produce the work, or an object code interpreter used to run it.</p> | |
145 | ||
146 | <p>The “Corresponding Source” for a work in object code form means all | |
147 | the source code needed to generate, install, and (for an executable | |
148 | work) run the object code and to modify the work, including scripts to | |
149 | control those activities. However, it does not include the work's | |
150 | System Libraries, or general-purpose tools or generally available free | |
151 | programs which are used unmodified in performing those activities but | |
152 | which are not part of the work. For example, Corresponding Source | |
153 | includes interface definition files associated with source files for | |
154 | the work, and the source code for shared libraries and dynamically | |
155 | linked subprograms that the work is specifically designed to require, | |
156 | such as by intimate data communication or control flow between those | |
157 | subprograms and other parts of the work.</p> | |
158 | ||
159 | <p>The Corresponding Source need not include anything that users | |
160 | can regenerate automatically from other parts of the Corresponding | |
161 | Source.</p> | |
162 | ||
163 | <p>The Corresponding Source for a work in source code form is that | |
164 | same work.</p> | |
165 | ||
166 | <h4><a name="section2"></a>2. Basic Permissions.</h4> | |
167 | ||
168 | <p>All rights granted under this License are granted for the term of | |
169 | copyright on the Program, and are irrevocable provided the stated | |
170 | conditions are met. This License explicitly affirms your unlimited | |
171 | permission to run the unmodified Program. The output from running a | |
172 | covered work is covered by this License only if the output, given its | |
173 | content, constitutes a covered work. This License acknowledges your | |
174 | rights of fair use or other equivalent, as provided by copyright law.</p> | |
175 | ||
176 | <p>You may make, run and propagate covered works that you do not | |
177 | convey, without conditions so long as your license otherwise remains | |
178 | in force. You may convey covered works to others for the sole purpose | |
179 | of having them make modifications exclusively for you, or provide you | |
180 | with facilities for running those works, provided that you comply with | |
181 | the terms of this License in conveying all material for which you do | |
182 | not control copyright. Those thus making or running the covered works | |
183 | for you must do so exclusively on your behalf, under your direction | |
184 | and control, on terms that prohibit them from making any copies of | |
185 | your copyrighted material outside their relationship with you.</p> | |
186 | ||
187 | <p>Conveying under any other circumstances is permitted solely under | |
188 | the conditions stated below. Sublicensing is not allowed; section 10 | |
189 | makes it unnecessary.</p> | |
190 | ||
191 | <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4> | |
192 | ||
193 | <p>No covered work shall be deemed part of an effective technological | |
194 | measure under any applicable law fulfilling obligations under article | |
195 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
196 | similar laws prohibiting or restricting circumvention of such | |
197 | measures.</p> | |
198 | ||
199 | <p>When you convey a covered work, you waive any legal power to forbid | |
200 | circumvention of technological measures to the extent such circumvention | |
201 | is effected by exercising rights under this License with respect to | |
202 | the covered work, and you disclaim any intention to limit operation or | |
203 | modification of the work as a means of enforcing, against the work's | |
204 | users, your or third parties' legal rights to forbid circumvention of | |
205 | technological measures.</p> | |
206 | ||
207 | <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4> | |
208 | ||
209 | <p>You may convey verbatim copies of the Program's source code as you | |
210 | receive it, in any medium, provided that you conspicuously and | |
211 | appropriately publish on each copy an appropriate copyright notice; | |
212 | keep intact all notices stating that this License and any | |
213 | non-permissive terms added in accord with section 7 apply to the code; | |
214 | keep intact all notices of the absence of any warranty; and give all | |
215 | recipients a copy of this License along with the Program.</p> | |
216 | ||
217 | <p>You may charge any price or no price for each copy that you convey, | |
218 | and you may offer support or warranty protection for a fee.</p> | |
219 | ||
220 | <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4> | |
221 | ||
222 | <p>You may convey a work based on the Program, or the modifications to | |
223 | produce it from the Program, in the form of source code under the | |
224 | terms of section 4, provided that you also meet all of these conditions:</p> | |
225 | ||
226 | <ul> | |
227 | <li>a) The work must carry prominent notices stating that you modified | |
228 | it, and giving a relevant date.</li> | |
229 | ||
230 | <li>b) The work must carry prominent notices stating that it is | |
231 | released under this License and any conditions added under section | |
232 | 7. This requirement modifies the requirement in section 4 to | |
233 | “keep intact all notices”.</li> | |
234 | ||
235 | <li>c) You must license the entire work, as a whole, under this | |
236 | License to anyone who comes into possession of a copy. This | |
237 | License will therefore apply, along with any applicable section 7 | |
238 | additional terms, to the whole of the work, and all its parts, | |
239 | regardless of how they are packaged. This License gives no | |
240 | permission to license the work in any other way, but it does not | |
241 | invalidate such permission if you have separately received it.</li> | |
242 | ||
243 | <li>d) If the work has interactive user interfaces, each must display | |
244 | Appropriate Legal Notices; however, if the Program has interactive | |
245 | interfaces that do not display Appropriate Legal Notices, your | |
246 | work need not make them do so.</li> | |
247 | </ul> | |
248 | ||
249 | <p>A compilation of a covered work with other separate and independent | |
250 | works, which are not by their nature extensions of the covered work, | |
251 | and which are not combined with it such as to form a larger program, | |
252 | in or on a volume of a storage or distribution medium, is called an | |
253 | “aggregate” if the compilation and its resulting copyright are not | |
254 | used to limit the access or legal rights of the compilation's users | |
255 | beyond what the individual works permit. Inclusion of a covered work | |
256 | in an aggregate does not cause this License to apply to the other | |
257 | parts of the aggregate.</p> | |
258 | ||
259 | <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4> | |
260 | ||
261 | <p>You may convey a covered work in object code form under the terms | |
262 | of sections 4 and 5, provided that you also convey the | |
263 | machine-readable Corresponding Source under the terms of this License, | |
264 | in one of these ways:</p> | |
265 | ||
266 | <ul> | |
267 | <li>a) Convey the object code in, or embodied in, a physical product | |
268 | (including a physical distribution medium), accompanied by the | |
269 | Corresponding Source fixed on a durable physical medium | |
270 | customarily used for software interchange.</li> | |
271 | ||
272 | <li>b) Convey the object code in, or embodied in, a physical product | |
273 | (including a physical distribution medium), accompanied by a | |
274 | written offer, valid for at least three years and valid for as | |
275 | long as you offer spare parts or customer support for that product | |
276 | model, to give anyone who possesses the object code either (1) a | |
277 | copy of the Corresponding Source for all the software in the | |
278 | product that is covered by this License, on a durable physical | |
279 | medium customarily used for software interchange, for a price no | |
280 | more than your reasonable cost of physically performing this | |
281 | conveying of source, or (2) access to copy the | |
282 | Corresponding Source from a network server at no charge.</li> | |
283 | ||
284 | <li>c) Convey individual copies of the object code with a copy of the | |
285 | written offer to provide the Corresponding Source. This | |
286 | alternative is allowed only occasionally and noncommercially, and | |
287 | only if you received the object code with such an offer, in accord | |
288 | with subsection 6b.</li> | |
289 | ||
290 | <li>d) Convey the object code by offering access from a designated | |
291 | place (gratis or for a charge), and offer equivalent access to the | |
292 | Corresponding Source in the same way through the same place at no | |
293 | further charge. You need not require recipients to copy the | |
294 | Corresponding Source along with the object code. If the place to | |
295 | copy the object code is a network server, the Corresponding Source | |
296 | may be on a different server (operated by you or a third party) | |
297 | that supports equivalent copying facilities, provided you maintain | |
298 | clear directions next to the object code saying where to find the | |
299 | Corresponding Source. Regardless of what server hosts the | |
300 | Corresponding Source, you remain obligated to ensure that it is | |
301 | available for as long as needed to satisfy these requirements.</li> | |
302 | ||
303 | <li>e) Convey the object code using peer-to-peer transmission, provided | |
304 | you inform other peers where the object code and Corresponding | |
305 | Source of the work are being offered to the general public at no | |
306 | charge under subsection 6d.</li> | |
307 | </ul> | |
308 | ||
309 | <p>A separable portion of the object code, whose source code is excluded | |
310 | from the Corresponding Source as a System Library, need not be | |
311 | included in conveying the object code work.</p> | |
312 | ||
313 | <p>A “User Product” is either (1) a “consumer product”, which means any | |
314 | tangible personal property which is normally used for personal, family, | |
315 | or household purposes, or (2) anything designed or sold for incorporation | |
316 | into a dwelling. In determining whether a product is a consumer product, | |
317 | doubtful cases shall be resolved in favor of coverage. For a particular | |
318 | product received by a particular user, “normally used” refers to a | |
319 | typical or common use of that class of product, regardless of the status | |
320 | of the particular user or of the way in which the particular user | |
321 | actually uses, or expects or is expected to use, the product. A product | |
322 | is a consumer product regardless of whether the product has substantial | |
323 | commercial, industrial or non-consumer uses, unless such uses represent | |
324 | the only significant mode of use of the product.</p> | |
325 | ||
326 | <p>“Installation Information” for a User Product means any methods, | |
327 | procedures, authorization keys, or other information required to install | |
328 | and execute modified versions of a covered work in that User Product from | |
329 | a modified version of its Corresponding Source. The information must | |
330 | suffice to ensure that the continued functioning of the modified object | |
331 | code is in no case prevented or interfered with solely because | |
332 | modification has been made.</p> | |
333 | ||
334 | <p>If you convey an object code work under this section in, or with, or | |
335 | specifically for use in, a User Product, and the conveying occurs as | |
336 | part of a transaction in which the right of possession and use of the | |
337 | User Product is transferred to the recipient in perpetuity or for a | |
338 | fixed term (regardless of how the transaction is characterized), the | |
339 | Corresponding Source conveyed under this section must be accompanied | |
340 | by the Installation Information. But this requirement does not apply | |
341 | if neither you nor any third party retains the ability to install | |
342 | modified object code on the User Product (for example, the work has | |
343 | been installed in ROM).</p> | |
344 | ||
345 | <p>The requirement to provide Installation Information does not include a | |
346 | requirement to continue to provide support service, warranty, or updates | |
347 | for a work that has been modified or installed by the recipient, or for | |
348 | the User Product in which it has been modified or installed. Access to a | |
349 | network may be denied when the modification itself materially and | |
350 | adversely affects the operation of the network or violates the rules and | |
351 | protocols for communication across the network.</p> | |
352 | ||
353 | <p>Corresponding Source conveyed, and Installation Information provided, | |
354 | in accord with this section must be in a format that is publicly | |
355 | documented (and with an implementation available to the public in | |
356 | source code form), and must require no special password or key for | |
357 | unpacking, reading or copying.</p> | |
358 | ||
359 | <h4><a name="section7"></a>7. Additional Terms.</h4> | |
360 | ||
361 | <p>“Additional permissions” are terms that supplement the terms of this | |
362 | License by making exceptions from one or more of its conditions. | |
363 | Additional permissions that are applicable to the entire Program shall | |
364 | be treated as though they were included in this License, to the extent | |
365 | that they are valid under applicable law. If additional permissions | |
366 | apply only to part of the Program, that part may be used separately | |
367 | under those permissions, but the entire Program remains governed by | |
368 | this License without regard to the additional permissions.</p> | |
369 | ||
370 | <p>When you convey a copy of a covered work, you may at your option | |
371 | remove any additional permissions from that copy, or from any part of | |
372 | it. (Additional permissions may be written to require their own | |
373 | removal in certain cases when you modify the work.) You may place | |
374 | additional permissions on material, added by you to a covered work, | |
375 | for which you have or can give appropriate copyright permission.</p> | |
376 | ||
377 | <p>Notwithstanding any other provision of this License, for material you | |
378 | add to a covered work, you may (if authorized by the copyright holders of | |
379 | that material) supplement the terms of this License with terms:</p> | |
380 | ||
381 | <ul> | |
382 | <li>a) Disclaiming warranty or limiting liability differently from the | |
383 | terms of sections 15 and 16 of this License; or</li> | |
384 | ||
385 | <li>b) Requiring preservation of specified reasonable legal notices or | |
386 | author attributions in that material or in the Appropriate Legal | |
387 | Notices displayed by works containing it; or</li> | |
388 | ||
389 | <li>c) Prohibiting misrepresentation of the origin of that material, or | |
390 | requiring that modified versions of such material be marked in | |
391 | reasonable ways as different from the original version; or</li> | |
392 | ||
393 | <li>d) Limiting the use for publicity purposes of names of licensors or | |
394 | authors of the material; or</li> | |
395 | ||
396 | <li>e) Declining to grant rights under trademark law for use of some | |
397 | trade names, trademarks, or service marks; or</li> | |
398 | ||
399 | <li>f) Requiring indemnification of licensors and authors of that | |
400 | material by anyone who conveys the material (or modified versions of | |
401 | it) with contractual assumptions of liability to the recipient, for | |
402 | any liability that these contractual assumptions directly impose on | |
403 | those licensors and authors.</li> | |
404 | </ul> | |
405 | ||
406 | <p>All other non-permissive additional terms are considered “further | |
407 | restrictions” within the meaning of section 10. If the Program as you | |
408 | received it, or any part of it, contains a notice stating that it is | |
409 | governed by this License along with a term that is a further | |
410 | restriction, you may remove that term. If a license document contains | |
411 | a further restriction but permits relicensing or conveying under this | |
412 | License, you may add to a covered work material governed by the terms | |
413 | of that license document, provided that the further restriction does | |
414 | not survive such relicensing or conveying.</p> | |
415 | ||
416 | <p>If you add terms to a covered work in accord with this section, you | |
417 | must place, in the relevant source files, a statement of the | |
418 | additional terms that apply to those files, or a notice indicating | |
419 | where to find the applicable terms.</p> | |
420 | ||
421 | <p>Additional terms, permissive or non-permissive, may be stated in the | |
422 | form of a separately written license, or stated as exceptions; | |
423 | the above requirements apply either way.</p> | |
424 | ||
425 | <h4><a name="section8"></a>8. Termination.</h4> | |
426 | ||
427 | <p>You may not propagate or modify a covered work except as expressly | |
428 | provided under this License. Any attempt otherwise to propagate or | |
429 | modify it is void, and will automatically terminate your rights under | |
430 | this License (including any patent licenses granted under the third | |
431 | paragraph of section 11).</p> | |
432 | ||
433 | <p>However, if you cease all violation of this License, then your | |
434 | license from a particular copyright holder is reinstated (a) | |
435 | provisionally, unless and until the copyright holder explicitly and | |
436 | finally terminates your license, and (b) permanently, if the copyright | |
437 | holder fails to notify you of the violation by some reasonable means | |
438 | prior to 60 days after the cessation.</p> | |
439 | ||
440 | <p>Moreover, your license from a particular copyright holder is | |
441 | reinstated permanently if the copyright holder notifies you of the | |
442 | violation by some reasonable means, this is the first time you have | |
443 | received notice of violation of this License (for any work) from that | |
444 | copyright holder, and you cure the violation prior to 30 days after | |
445 | your receipt of the notice.</p> | |
446 | ||
447 | <p>Termination of your rights under this section does not terminate the | |
448 | licenses of parties who have received copies or rights from you under | |
449 | this License. If your rights have been terminated and not permanently | |
450 | reinstated, you do not qualify to receive new licenses for the same | |
451 | material under section 10.</p> | |
452 | ||
453 | <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4> | |
454 | ||
455 | <p>You are not required to accept this License in order to receive or | |
456 | run a copy of the Program. Ancillary propagation of a covered work | |
457 | occurring solely as a consequence of using peer-to-peer transmission | |
458 | to receive a copy likewise does not require acceptance. However, | |
459 | nothing other than this License grants you permission to propagate or | |
460 | modify any covered work. These actions infringe copyright if you do | |
461 | not accept this License. Therefore, by modifying or propagating a | |
462 | covered work, you indicate your acceptance of this License to do so.</p> | |
463 | ||
464 | <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4> | |
465 | ||
466 | <p>Each time you convey a covered work, the recipient automatically | |
467 | receives a license from the original licensors, to run, modify and | |
468 | propagate that work, subject to this License. You are not responsible | |
469 | for enforcing compliance by third parties with this License.</p> | |
470 | ||
471 | <p>An “entity transaction” is a transaction transferring control of an | |
472 | organization, or substantially all assets of one, or subdividing an | |
473 | organization, or merging organizations. If propagation of a covered | |
474 | work results from an entity transaction, each party to that | |
475 | transaction who receives a copy of the work also receives whatever | |
476 | licenses to the work the party's predecessor in interest had or could | |
477 | give under the previous paragraph, plus a right to possession of the | |
478 | Corresponding Source of the work from the predecessor in interest, if | |
479 | the predecessor has it or can get it with reasonable efforts.</p> | |
480 | ||
481 | <p>You may not impose any further restrictions on the exercise of the | |
482 | rights granted or affirmed under this License. For example, you may | |
483 | not impose a license fee, royalty, or other charge for exercise of | |
484 | rights granted under this License, and you may not initiate litigation | |
485 | (including a cross-claim or counterclaim in a lawsuit) alleging that | |
486 | any patent claim is infringed by making, using, selling, offering for | |
487 | sale, or importing the Program or any portion of it.</p> | |
488 | ||
489 | <h4><a name="section11"></a>11. Patents.</h4> | |
490 | ||
491 | <p>A “contributor” is a copyright holder who authorizes use under this | |
492 | License of the Program or a work on which the Program is based. The | |
493 | work thus licensed is called the contributor's “contributor version”.</p> | |
494 | ||
495 | <p>A contributor's “essential patent claims” are all patent claims | |
496 | owned or controlled by the contributor, whether already acquired or | |
497 | hereafter acquired, that would be infringed by some manner, permitted | |
498 | by this License, of making, using, or selling its contributor version, | |
499 | but do not include claims that would be infringed only as a | |
500 | consequence of further modification of the contributor version. For | |
501 | purposes of this definition, “control” includes the right to grant | |
502 | patent sublicenses in a manner consistent with the requirements of | |
503 | this License.</p> | |
504 | ||
505 | <p>Each contributor grants you a non-exclusive, worldwide, royalty-free | |
506 | patent license under the contributor's essential patent claims, to | |
507 | make, use, sell, offer for sale, import and otherwise run, modify and | |
508 | propagate the contents of its contributor version.</p> | |
509 | ||
510 | <p>In the following three paragraphs, a “patent license” is any express | |
511 | agreement or commitment, however denominated, not to enforce a patent | |
512 | (such as an express permission to practice a patent or covenant not to | |
513 | sue for patent infringement). To “grant” such a patent license to a | |
514 | party means to make such an agreement or commitment not to enforce a | |
515 | patent against the party.</p> | |
516 | ||
517 | <p>If you convey a covered work, knowingly relying on a patent license, | |
518 | and the Corresponding Source of the work is not available for anyone | |
519 | to copy, free of charge and under the terms of this License, through a | |
520 | publicly available network server or other readily accessible means, | |
521 | then you must either (1) cause the Corresponding Source to be so | |
522 | available, or (2) arrange to deprive yourself of the benefit of the | |
523 | patent license for this particular work, or (3) arrange, in a manner | |
524 | consistent with the requirements of this License, to extend the patent | |
525 | license to downstream recipients. “Knowingly relying” means you have | |
526 | actual knowledge that, but for the patent license, your conveying the | |
527 | covered work in a country, or your recipient's use of the covered work | |
528 | in a country, would infringe one or more identifiable patents in that | |
529 | country that you have reason to believe are valid.</p> | |
530 | ||
531 | <p>If, pursuant to or in connection with a single transaction or | |
532 | arrangement, you convey, or propagate by procuring conveyance of, a | |
533 | covered work, and grant a patent license to some of the parties | |
534 | receiving the covered work authorizing them to use, propagate, modify | |
535 | or convey a specific copy of the covered work, then the patent license | |
536 | you grant is automatically extended to all recipients of the covered | |
537 | work and works based on it.</p> | |
538 | ||
539 | <p>A patent license is “discriminatory” if it does not include within | |
540 | the scope of its coverage, prohibits the exercise of, or is | |
541 | conditioned on the non-exercise of one or more of the rights that are | |
542 | specifically granted under this License. You may not convey a covered | |
543 | work if you are a party to an arrangement with a third party that is | |
544 | in the business of distributing software, under which you make payment | |
545 | to the third party based on the extent of your activity of conveying | |
546 | the work, and under which the third party grants, to any of the | |
547 | parties who would receive the covered work from you, a discriminatory | |
548 | patent license (a) in connection with copies of the covered work | |
549 | conveyed by you (or copies made from those copies), or (b) primarily | |
550 | for and in connection with specific products or compilations that | |
551 | contain the covered work, unless you entered into that arrangement, | |
552 | or that patent license was granted, prior to 28 March 2007.</p> | |
553 | ||
554 | <p>Nothing in this License shall be construed as excluding or limiting | |
555 | any implied license or other defenses to infringement that may | |
556 | otherwise be available to you under applicable patent law.</p> | |
557 | ||
558 | <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4> | |
559 | ||
560 | <p>If conditions are imposed on you (whether by court order, agreement or | |
561 | otherwise) that contradict the conditions of this License, they do not | |
562 | excuse you from the conditions of this License. If you cannot convey a | |
563 | covered work so as to satisfy simultaneously your obligations under this | |
564 | License and any other pertinent obligations, then as a consequence you may | |
565 | not convey it at all. For example, if you agree to terms that obligate you | |
566 | to collect a royalty for further conveying from those to whom you convey | |
567 | the Program, the only way you could satisfy both those terms and this | |
568 | License would be to refrain entirely from conveying the Program.</p> | |
569 | ||
570 | <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4> | |
571 | ||
572 | <p>Notwithstanding any other provision of this License, you have | |
573 | permission to link or combine any covered work with a work licensed | |
574 | under version 3 of the GNU Affero General Public License into a single | |
575 | combined work, and to convey the resulting work. The terms of this | |
576 | License will continue to apply to the part which is the covered work, | |
577 | but the special requirements of the GNU Affero General Public License, | |
578 | section 13, concerning interaction through a network will apply to the | |
579 | combination as such.</p> | |
580 | ||
581 | <h4><a name="section14"></a>14. Revised Versions of this License.</h4> | |
582 | ||
583 | <p>The Free Software Foundation may publish revised and/or new versions of | |
584 | the GNU General Public License from time to time. Such new versions will | |
585 | be similar in spirit to the present version, but may differ in detail to | |
586 | address new problems or concerns.</p> | |
587 | ||
588 | <p>Each version is given a distinguishing version number. If the | |
589 | Program specifies that a certain numbered version of the GNU General | |
590 | Public License “or any later version” applies to it, you have the | |
591 | option of following the terms and conditions either of that numbered | |
592 | version or of any later version published by the Free Software | |
593 | Foundation. If the Program does not specify a version number of the | |
594 | GNU General Public License, you may choose any version ever published | |
595 | by the Free Software Foundation.</p> | |
596 | ||
597 | <p>If the Program specifies that a proxy can decide which future | |
598 | versions of the GNU General Public License can be used, that proxy's | |
599 | public statement of acceptance of a version permanently authorizes you | |
600 | to choose that version for the Program.</p> | |
601 | ||
602 | <p>Later license versions may give you additional or different | |
603 | permissions. However, no additional obligations are imposed on any | |
604 | author or copyright holder as a result of your choosing to follow a | |
605 | later version.</p> | |
606 | ||
607 | <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4> | |
608 | ||
609 | <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
610 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
611 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY | |
612 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, | |
613 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
614 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM | |
615 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF | |
616 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p> | |
617 | ||
618 | <h4><a name="section16"></a>16. Limitation of Liability.</h4> | |
619 | ||
620 | <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
621 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS | |
622 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY | |
623 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE | |
624 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF | |
625 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD | |
626 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), | |
627 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF | |
628 | SUCH DAMAGES.</p> | |
629 | ||
630 | <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4> | |
631 | ||
632 | <p>If the disclaimer of warranty and limitation of liability provided | |
633 | above cannot be given local legal effect according to their terms, | |
634 | reviewing courts shall apply local law that most closely approximates | |
635 | an absolute waiver of all civil liability in connection with the | |
636 | Program, unless a warranty or assumption of liability accompanies a | |
637 | copy of the Program in return for a fee.</p> | |
638 | ||
639 | <p>END OF TERMS AND CONDITIONS</p> | |
640 | ||
641 | <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3> | |
642 | ||
643 | <p>If you develop a new program, and you want it to be of the greatest | |
644 | possible use to the public, the best way to achieve this is to make it | |
645 | free software which everyone can redistribute and change under these terms.</p> | |
646 | ||
647 | <p>To do so, attach the following notices to the program. It is safest | |
648 | to attach them to the start of each source file to most effectively | |
649 | state the exclusion of warranty; and each file should have at least | |
650 | the “copyright” line and a pointer to where the full notice is found.</p> | |
651 | ||
652 | <pre> <one line to give the program's name and a brief idea of what it does.> | |
653 | Copyright (C) <year> <name of author> | |
654 | ||
655 | This program is free software: you can redistribute it and/or modify | |
656 | it under the terms of the GNU General Public License as published by | |
657 | the Free Software Foundation, either version 3 of the License, or | |
658 | (at your option) any later version. | |
659 | ||
660 | This program is distributed in the hope that it will be useful, | |
661 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
662 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
663 | GNU General Public License for more details. | |
664 | ||
665 | You should have received a copy of the GNU General Public License | |
666 | along with this program. If not, see <https://www.gnu.org/licenses/>. | |
667 | </pre> | |
668 | ||
669 | <p>Also add information on how to contact you by electronic and paper mail.</p> | |
670 | ||
671 | <p>If the program does terminal interaction, make it output a short | |
672 | notice like this when it starts in an interactive mode:</p> | |
673 | ||
674 | <pre> <program> Copyright (C) <year> <name of author> | |
675 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
676 | This is free software, and you are welcome to redistribute it | |
677 | under certain conditions; type `show c' for details. | |
678 | </pre> | |
679 | ||
680 | <p>The hypothetical commands `show w' and `show c' should show the appropriate | |
681 | parts of the General Public License. Of course, your program's commands | |
682 | might be different; for a GUI interface, you would use an “about box”.</p> | |
683 | ||
684 | <p>You should also get your employer (if you work as a programmer) or school, | |
685 | if any, to sign a “copyright disclaimer” for the program, if necessary. | |

688 | ||
689 | <p>The GNU General Public License does not permit incorporating your program | |
690 | into proprietary programs. If your program is a subroutine library, you | |
691 | may consider it more useful to permit linking proprietary applications with | |
692 | the library. If this is what you want to do, use the GNU Lesser General | |
693 | Public License instead of this License. But first, please read | |
