108 <h2 class="heading"> Preamble </h2> | |
109 | |
110 <p>The GNU General Public License is a free, copyleft license for | |
111 software and other kinds of works. | |
112 </p> | |
113 <p>The licenses for most software and other practical works are designed | |
114 to take away your freedom to share and change the works. By contrast, | |
115 the GNU General Public License is intended to guarantee your freedom | |
116 to share and change all versions of a program—to make sure it remains | |
117 free software for all its users. We, the Free Software Foundation, | |
118 use the GNU General Public License for most of our software; it | |
119 applies also to any other work released this way by its authors. You | |
120 can apply it to your programs, too. | |
121 </p> | |
122 <p>When we speak of free software, we are referring to freedom, not | |
123 price. Our General Public Licenses are designed to make sure that you | |
124 have the freedom to distribute copies of free software (and charge for | |
125 them if you wish), that you receive source code or can get it if you | |
126 want it, that you can change the software or use pieces of it in new | |
127 free programs, and that you know you can do these things. | |
128 </p> | |
129 <p>To protect your rights, we need to prevent others from denying you | |
130 these rights or asking you to surrender the rights. Therefore, you | |
131 have certain responsibilities if you distribute copies of the | |
132 software, or if you modify it: responsibilities to respect the freedom | |
133 of others. | |
134 </p> | |
135 <p>For example, if you distribute copies of such a program, whether | |
136 gratis or for a fee, you must pass on to the recipients the same | |
137 freedoms that you received. You must make sure that they, too, | |
138 receive or can get the source code. And you must show them these | |
139 terms so they know their rights. | |
140 </p> | |
141 <p>Developers that use the GNU GPL protect your rights with two steps: | |
142 (1) assert copyright on the software, and (2) offer you this License | |
143 giving you legal permission to copy, distribute and/or modify it. | |
144 </p> | |
145 <p>For the developers' and authors' protection, the GPL clearly explains | |
146 that there is no warranty for this free software. For both users' and | |
147 authors' sake, the GPL requires that modified versions be marked as | |
148 changed, so that their problems will not be attributed erroneously to | |
149 authors of previous versions. | |
150 </p> | |
151 <p>Some devices are designed to deny users access to install or run | |
152 modified versions of the software inside them, although the | |
153 manufacturer can do so. This is fundamentally incompatible with the | |
154 aim of protecting users' freedom to change the software. The | |
155 systematic pattern of such abuse occurs in the area of products for | |
156 individuals to use, which is precisely where it is most unacceptable. | |
157 Therefore, we have designed this version of the GPL to prohibit the | |
158 practice for those products. If such problems arise substantially in | |
159 other domains, we stand ready to extend this provision to those | |
160 domains in future versions of the GPL, as needed to protect the | |
161 freedom of users. | |
162 </p> | |
163 <p>Finally, every program is threatened constantly by software patents. | |
164 States should not allow patents to restrict development and use of | |
165 software on general-purpose computers, but in those that do, we wish | |
166 to avoid the special danger that patents applied to a free program | |
167 could make it effectively proprietary. To prevent this, the GPL | |
168 assures that patents cannot be used to render the program non-free. | |
169 </p> | |
170 <p>The precise terms and conditions for copying, distribution and | |
171 modification follow. | |
172 </p> | |
173 <a name="SEC41"></a> | |
174 <h2 class="heading"> TERMS AND CONDITIONS </h2> | |
175 | |
176 <ol> | |
177 <li> Definitions. | |
178 | |
179 <p>“This License” refers to version 3 of the GNU General Public License. | |
180 </p> | |
181 <p>“Copyright” also means copyright-like laws that apply to other kinds | |
182 of works, such as semiconductor masks. | |
183 </p> | |
184 <p>“The Program” refers to any copyrightable work licensed under this | |
185 License. Each licensee is addressed as “you”. “Licensees” and | |
186 “recipients” may be individuals or organizations. | |
187 </p> | |
188 <p>To “modify” a work means to copy from or adapt all or part of the work | |
189 in a fashion requiring copyright permission, other than the making of | |
190 an exact copy. The resulting work is called a “modified version” of | |
191 the earlier work or a work “based on” the earlier work. | |
192 </p> | |
193 <p>A “covered work” means either the unmodified Program or a work based | |
194 on the Program. | |
195 </p> | |
196 <p>To “propagate” a work means to do anything with it that, without | |
197 permission, would make you directly or secondarily liable for | |
198 infringement under applicable copyright law, except executing it on a | |
199 computer or modifying a private copy. Propagation includes copying, | |
200 distribution (with or without modification), making available to the | |
201 public, and in some countries other activities as well. | |
202 </p> | |
203 <p>To “convey” a work means any kind of propagation that enables other | |
204 parties to make or receive copies. Mere interaction with a user | |
205 through a computer network, with no transfer of a copy, is not | |
206 conveying. | |
207 </p> | |
208 <p>An interactive user interface displays “Appropriate Legal Notices” to | |
209 the extent that it includes a convenient and prominently visible | |
210 feature that (1) displays an appropriate copyright notice, and (2) | |
211 tells the user that there is no warranty for the work (except to the | |
212 extent that warranties are provided), that licensees may convey the | |
213 work under this License, and how to view a copy of this License. If | |
214 the interface presents a list of user commands or options, such as a | |
215 menu, a prominent item in the list meets this criterion. | |
216 </p> | |
217 </li><li> Source Code. | |
218 | |
219 <p>The “source code” for a work means the preferred form of the work for | |
220 making modifications to it. “Object code” means any non-source form | |
221 of a work. | |
222 </p> | |
223 <p>A “Standard Interface” means an interface that either is an official | |
224 standard defined by a recognized standards body, or, in the case of | |
225 interfaces specified for a particular programming language, one that | |
226 is widely used among developers working in that language. | |
227 </p> | |
228 <p>The “System Libraries” of an executable work include anything, other | |
229 than the work as a whole, that (a) is included in the normal form of | |
230 packaging a Major Component, but which is not part of that Major | |
231 Component, and (b) serves only to enable use of the work with that | |
232 Major Component, or to implement a Standard Interface for which an | |
233 implementation is available to the public in source code form. A | |
234 “Major Component”, in this context, means a major essential component | |
235 (kernel, window system, and so on) of the specific operating system | |
236 (if any) on which the executable work runs, or a compiler used to | |
237 produce the work, or an object code interpreter used to run it. | |
238 </p> | |
239 <p>The “Corresponding Source” for a work in object code form means all | |
240 the source code needed to generate, install, and (for an executable | |
241 work) run the object code and to modify the work, including scripts to | |
242 control those activities. However, it does not include the work's | |
243 System Libraries, or general-purpose tools or generally available free | |
244 programs which are used unmodified in performing those activities but | |
245 which are not part of the work. For example, Corresponding Source | |
246 includes interface definition files associated with source files for | |
247 the work, and the source code for shared libraries and dynamically | |
248 linked subprograms that the work is specifically designed to require, | |
249 such as by intimate data communication or control flow between those | |
250 subprograms and other parts of the work. | |
251 </p> | |
252 <p>The Corresponding Source need not include anything that users can | |
253 regenerate automatically from other parts of the Corresponding Source. | |
254 </p> | |
255 <p>The Corresponding Source for a work in source code form is that same | |
256 work. | |
257 </p> | |
258 </li><li> Basic Permissions. | |
259 | |
260 <p>All rights granted under this License are granted for the term of | |
261 copyright on the Program, and are irrevocable provided the stated | |
262 conditions are met. This License explicitly affirms your unlimited | |
263 permission to run the unmodified Program. The output from running a | |
264 covered work is covered by this License only if the output, given its | |
265 content, constitutes a covered work. This License acknowledges your | |
266 rights of fair use or other equivalent, as provided by copyright law. | |
267 </p> | |
268 <p>You may make, run and propagate covered works that you do not convey, | |
269 without conditions so long as your license otherwise remains in force. | |
270 You may convey covered works to others for the sole purpose of having | |
271 them make modifications exclusively for you, or provide you with | |
272 facilities for running those works, provided that you comply with the | |
273 terms of this License in conveying all material for which you do not | |
274 control copyright. Those thus making or running the covered works for | |
275 you must do so exclusively on your behalf, under your direction and | |
276 control, on terms that prohibit them from making any copies of your | |
277 copyrighted material outside their relationship with you. | |
278 </p> | |
279 <p>Conveying under any other circumstances is permitted solely under the | |
280 conditions stated below. Sublicensing is not allowed; section 10 | |
281 makes it unnecessary. | |
282 </p> | |
283 </li><li> Protecting Users' Legal Rights From Anti-Circumvention Law. | |
284 | |
285 <p>No covered work shall be deemed part of an effective technological | |
286 measure under any applicable law fulfilling obligations under article | |
287 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
288 similar laws prohibiting or restricting circumvention of such | |
289 measures. | |
290 </p> | |
291 <p>When you convey a covered work, you waive any legal power to forbid | |
292 circumvention of technological measures to the extent such | |
293 circumvention is effected by exercising rights under this License with | |
294 respect to the covered work, and you disclaim any intention to limit | |
295 operation or modification of the work as a means of enforcing, against | |
296 the work's users, your or third parties' legal rights to forbid | |
297 circumvention of technological measures. | |
298 </p> | |
299 </li><li> Conveying Verbatim Copies. | |
300 | |
301 <p>You may convey verbatim copies of the Program's source code as you | |
302 receive it, in any medium, provided that you conspicuously and | |
303 appropriately publish on each copy an appropriate copyright notice; | |
304 keep intact all notices stating that this License and any | |
305 non-permissive terms added in accord with section 7 apply to the code; | |
306 keep intact all notices of the absence of any warranty; and give all | |
307 recipients a copy of this License along with the Program. | |
308 </p> | |
309 <p>You may charge any price or no price for each copy that you convey, | |
310 and you may offer support or warranty protection for a fee. | |
311 </p> | |
312 </li><li> Conveying Modified Source Versions. | |
313 | |
314 <p>You may convey a work based on the Program, or the modifications to | |
315 produce it from the Program, in the form of source code under the | |
316 terms of section 4, provided that you also meet all of these | |
317 conditions: | |
318 </p> | |
319 <ol> | |
320 <li> | |
321 The work must carry prominent notices stating that you modified it, | |
322 and giving a relevant date. | |
323 | |
324 </li><li> | |
325 The work must carry prominent notices stating that it is released | |
326 under this License and any conditions added under section 7. This | |
327 requirement modifies the requirement in section 4 to “keep intact all | |
328 notices”. | |
329 | |
330 </li><li> | |
331 You must license the entire work, as a whole, under this License to | |
332 anyone who comes into possession of a copy. This License will | |
333 therefore apply, along with any applicable section 7 additional terms, | |
334 to the whole of the work, and all its parts, regardless of how they | |
335 are packaged. This License gives no permission to license the work in | |
336 any other way, but it does not invalidate such permission if you have | |
337 separately received it. | |
338 | |
339 </li><li> | |
340 If the work has interactive user interfaces, each must display | |
341 Appropriate Legal Notices; however, if the Program has interactive | |
342 interfaces that do not display Appropriate Legal Notices, your work | |
343 need not make them do so. | |
344 </li></ol> | |
345 | |
346 <p>A compilation of a covered work with other separate and independent | |
347 works, which are not by their nature extensions of the covered work, | |
348 and which are not combined with it such as to form a larger program, | |
349 in or on a volume of a storage or distribution medium, is called an | |
350 “aggregate” if the compilation and its resulting copyright are not | |
351 used to limit the access or legal rights of the compilation's users | |
352 beyond what the individual works permit. Inclusion of a covered work | |
353 in an aggregate does not cause this License to apply to the other | |
354 parts of the aggregate. | |
355 </p> | |
356 </li><li> Conveying Non-Source Forms. | |
357 | |
358 <p>You may convey a covered work in object code form under the terms of | |
359 sections 4 and 5, provided that you also convey the machine-readable | |
360 Corresponding Source under the terms of this License, in one of these | |
361 ways: | |
362 </p> | |
363 <ol> | |
364 <li> | |
365 Convey the object code in, or embodied in, a physical product | |
366 (including a physical distribution medium), accompanied by the | |
367 Corresponding Source fixed on a durable physical medium customarily | |
368 used for software interchange. | |
369 | |
370 </li><li> | |
371 Convey the object code in, or embodied in, a physical product | |
372 (including a physical distribution medium), accompanied by a written | |
373 offer, valid for at least three years and valid for as long as you | |
374 offer spare parts or customer support for that product model, to give | |
375 anyone who possesses the object code either (1) a copy of the | |
376 Corresponding Source for all the software in the product that is | |
377 covered by this License, on a durable physical medium customarily used | |
378 for software interchange, for a price no more than your reasonable | |
379 cost of physically performing this conveying of source, or (2) access | |
380 to copy the Corresponding Source from a network server at no charge. | |
381 | |
382 </li><li> | |
383 Convey individual copies of the object code with a copy of the written | |
384 offer to provide the Corresponding Source. This alternative is | |
385 allowed only occasionally and noncommercially, and only if you | |
386 received the object code with such an offer, in accord with subsection | |
387 6b. | |
388 | |
389 </li><li> | |
390 Convey the object code by offering access from a designated place | |
391 (gratis or for a charge), and offer equivalent access to the | |
392 Corresponding Source in the same way through the same place at no | |
393 further charge. You need not require recipients to copy the | |
394 Corresponding Source along with the object code. If the place to copy | |
395 the object code is a network server, the Corresponding Source may be | |
396 on a different server (operated by you or a third party) that supports | |
397 equivalent copying facilities, provided you maintain clear directions | |
398 next to the object code saying where to find the Corresponding Source. | |
399 Regardless of what server hosts the Corresponding Source, you remain | |
400 obligated to ensure that it is available for as long as needed to | |
401 satisfy these requirements. | |
402 | |
403 </li><li> | |
404 Convey the object code using peer-to-peer transmission, provided you | |
405 inform other peers where the object code and Corresponding Source of | |
406 the work are being offered to the general public at no charge under | |
407 subsection 6d. | |
408 | |
409 </li></ol> | |
410 | |
411 <p>A separable portion of the object code, whose source code is excluded | |
412 from the Corresponding Source as a System Library, need not be | |
413 included in conveying the object code work. | |
414 </p> | |
415 <p>A “User Product” is either (1) a “consumer product”, which means any | |
416 tangible personal property which is normally used for personal, | |
417 family, or household purposes, or (2) anything designed or sold for | |
418 incorporation into a dwelling. In determining whether a product is a | |
419 consumer product, doubtful cases shall be resolved in favor of | |
420 coverage. For a particular product received by a particular user, | |
421 “normally used” refers to a typical or common use of that class of | |
422 product, regardless of the status of the particular user or of the way | |
423 in which the particular user actually uses, or expects or is expected | |
424 to use, the product. A product is a consumer product regardless of | |
425 whether the product has substantial commercial, industrial or | |
426 non-consumer uses, unless such uses represent the only significant | |
427 mode of use of the product. | |
428 </p> | |
429 <p>“Installation Information” for a User Product means any methods, | |
430 procedures, authorization keys, or other information required to | |
431 install and execute modified versions of a covered work in that User | |
432 Product from a modified version of its Corresponding Source. The | |
433 information must suffice to ensure that the continued functioning of | |
434 the modified object code is in no case prevented or interfered with | |
435 solely because modification has been made. | |
436 </p> | |
437 <p>If you convey an object code work under this section in, or with, or | |
438 specifically for use in, a User Product, and the conveying occurs as | |
439 part of a transaction in which the right of possession and use of the | |
440 User Product is transferred to the recipient in perpetuity or for a | |
441 fixed term (regardless of how the transaction is characterized), the | |
442 Corresponding Source conveyed under this section must be accompanied | |
443 by the Installation Information. But this requirement does not apply | |
444 if neither you nor any third party retains the ability to install | |
445 modified object code on the User Product (for example, the work has | |
446 been installed in ROM). | |
447 </p> | |
448 <p>The requirement to provide Installation Information does not include a | |
449 requirement to continue to provide support service, warranty, or | |
450 updates for a work that has been modified or installed by the | |
451 recipient, or for the User Product in which it has been modified or | |
452 installed. Access to a network may be denied when the modification | |
453 itself materially and adversely affects the operation of the network | |
454 or violates the rules and protocols for communication across the | |
455 network. | |
456 </p> | |
457 <p>Corresponding Source conveyed, and Installation Information provided, | |
458 in accord with this section must be in a format that is publicly | |
459 documented (and with an implementation available to the public in | |
460 source code form), and must require no special password or key for | |
461 unpacking, reading or copying. | |
462 </p> | |
463 </li><li> Additional Terms. | |
464 | |
465 <p>“Additional permissions” are terms that supplement the terms of this | |
466 License by making exceptions from one or more of its conditions. | |
467 Additional permissions that are applicable to the entire Program shall | |
468 be treated as though they were included in this License, to the extent | |
469 that they are valid under applicable law. If additional permissions | |
470 apply only to part of the Program, that part may be used separately | |
471 under those permissions, but the entire Program remains governed by | |
472 this License without regard to the additional permissions. | |
473 </p> | |
474 <p>When you convey a copy of a covered work, you may at your option | |
475 remove any additional permissions from that copy, or from any part of | |
476 it. (Additional permissions may be written to require their own | |
477 removal in certain cases when you modify the work.) You may place | |
478 additional permissions on material, added by you to a covered work, | |
479 for which you have or can give appropriate copyright permission. | |
480 </p> | |
481 <p>Notwithstanding any other provision of this License, for material you | |
482 add to a covered work, you may (if authorized by the copyright holders | |
483 of that material) supplement the terms of this License with terms: | |
484 </p> | |
485 <ol> | |
486 <li> | |
487 Disclaiming warranty or limiting liability differently from the terms | |
488 of sections 15 and 16 of this License; or | |
489 | |
490 </li><li> | |
491 Requiring preservation of specified reasonable legal notices or author | |
492 attributions in that material or in the Appropriate Legal Notices | |
493 displayed by works containing it; or | |
494 | |
495 </li><li> | |
496 Prohibiting misrepresentation of the origin of that material, or | |
497 requiring that modified versions of such material be marked in | |
498 reasonable ways as different from the original version; or | |
499 | |
500 </li><li> | |
501 Limiting the use for publicity purposes of names of licensors or | |
502 authors of the material; or | |
503 | |
504 </li><li> | |
505 Declining to grant rights under trademark law for use of some trade | |
506 names, trademarks, or service marks; or | |
507 | |
508 </li><li> | |
509 Requiring indemnification of licensors and authors of that material by | |
510 anyone who conveys the material (or modified versions of it) with | |
511 contractual assumptions of liability to the recipient, for any | |
512 liability that these contractual assumptions directly impose on those | |
513 licensors and authors. | |
514 </li></ol> | |
515 | |
516 <p>All other non-permissive additional terms are considered “further | |
517 restrictions” within the meaning of section 10. If the Program as you | |
518 received it, or any part of it, contains a notice stating that it is | |
519 governed by this License along with a term that is a further | |
520 restriction, you may remove that term. If a license document contains | |
521 a further restriction but permits relicensing or conveying under this | |
522 License, you may add to a covered work material governed by the terms | |
523 of that license document, provided that the further restriction does | |
524 not survive such relicensing or conveying. | |
525 </p> | |
526 <p>If you add terms to a covered work in accord with this section, you | |
527 must place, in the relevant source files, a statement of the | |
528 additional terms that apply to those files, or a notice indicating | |
529 where to find the applicable terms. | |
530 </p> | |
531 <p>Additional terms, permissive or non-permissive, may be stated in the | |
532 form of a separately written license, or stated as exceptions; the | |
533 above requirements apply either way. | |
534 </p> | |
535 </li><li> Termination. | |
536 | |
537 <p>You may not propagate or modify a covered work except as expressly | |
538 provided under this License. Any attempt otherwise to propagate or | |
539 modify it is void, and will automatically terminate your rights under | |
540 this License (including any patent licenses granted under the third | |
541 paragraph of section 11). | |
542 </p> | |
543 <p>However, if you cease all violation of this License, then your license | |
544 from a particular copyright holder is reinstated (a) provisionally, | |
545 unless and until the copyright holder explicitly and finally | |
546 terminates your license, and (b) permanently, if the copyright holder | |
547 fails to notify you of the violation by some reasonable means prior to | |
548 60 days after the cessation. | |
549 </p> | |
550 <p>Moreover, your license from a particular copyright holder is | |
551 reinstated permanently if the copyright holder notifies you of the | |
552 violation by some reasonable means, this is the first time you have | |
553 received notice of violation of this License (for any work) from that | |
554 copyright holder, and you cure the violation prior to 30 days after | |
555 your receipt of the notice. | |
556 </p> | |
557 <p>Termination of your rights under this section does not terminate the | |
558 licenses of parties who have received copies or rights from you under | |
559 this License. If your rights have been terminated and not permanently | |
560 reinstated, you do not qualify to receive new licenses for the same | |
561 material under section 10. | |
562 </p> | |
563 </li><li> Acceptance Not Required for Having Copies. | |
564 | |
565 <p>You are not required to accept this License in order to receive or run | |
566 a copy of the Program. Ancillary propagation of a covered work | |
567 occurring solely as a consequence of using peer-to-peer transmission | |
568 to receive a copy likewise does not require acceptance. However, | |
569 nothing other than this License grants you permission to propagate or | |
570 modify any covered work. These actions infringe copyright if you do | |
571 not accept this License. Therefore, by modifying or propagating a | |
572 covered work, you indicate your acceptance of this License to do so. | |
573 </p> | |
574 </li><li> Automatic Licensing of Downstream Recipients. | |
575 | |
576 <p>Each time you convey a covered work, the recipient automatically | |
577 receives a license from the original licensors, to run, modify and | |
578 propagate that work, subject to this License. You are not responsible | |
579 for enforcing compliance by third parties with this License. | |
580 </p> | |
581 <p>An “entity transaction” is a transaction transferring control of an | |
582 organization, or substantially all assets of one, or subdividing an | |
583 organization, or merging organizations. If propagation of a covered | |
584 work results from an entity transaction, each party to that | |
585 transaction who receives a copy of the work also receives whatever | |
586 licenses to the work the party's predecessor in interest had or could | |
587 give under the previous paragraph, plus a right to possession of the | |
588 Corresponding Source of the work from the predecessor in interest, if | |
589 the predecessor has it or can get it with reasonable efforts. | |
590 </p> | |
591 <p>You may not impose any further restrictions on the exercise of the | |
592 rights granted or affirmed under this License. For example, you may | |
593 not impose a license fee, royalty, or other charge for exercise of | |
594 rights granted under this License, and you may not initiate litigation | |
595 (including a cross-claim or counterclaim in a lawsuit) alleging that | |
596 any patent claim is infringed by making, using, selling, offering for | |
597 sale, or importing the Program or any portion of it. | |
598 </p> | |
599 </li><li> Patents. | |
600 | |
601 <p>A “contributor” is a copyright holder who authorizes use under this | |
602 License of the Program or a work on which the Program is based. The | |
603 work thus licensed is called the contributor's “contributor version”. | |
604 </p> | |
605 <p>A contributor's “essential patent claims” are all patent claims owned | |
606 or controlled by the contributor, whether already acquired or | |
607 hereafter acquired, that would be infringed by some manner, permitted | |
608 by this License, of making, using, or selling its contributor version, | |
609 but do not include claims that would be infringed only as a | |
610 consequence of further modification of the contributor version. For | |
611 purposes of this definition, “control” includes the right to grant | |
612 patent sublicenses in a manner consistent with the requirements of | |
613 this License. | |
614 </p> | |
615 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free | |
616 patent license under the contributor's essential patent claims, to | |
617 make, use, sell, offer for sale, import and otherwise run, modify and | |
618 propagate the contents of its contributor version. | |
619 </p> | |
620 <p>In the following three paragraphs, a “patent license” is any express | |
621 agreement or commitment, however denominated, not to enforce a patent | |
622 (such as an express permission to practice a patent or covenant not to | |
623 sue for patent infringement). To “grant” such a patent license to a | |
624 party means to make such an agreement or commitment not to enforce a | |
625 patent against the party. | |
626 </p> | |
627 <p>If you convey a covered work, knowingly relying on a patent license, | |
628 and the Corresponding Source of the work is not available for anyone | |
629 to copy, free of charge and under the terms of this License, through a | |
630 publicly available network server or other readily accessible means, | |
631 then you must either (1) cause the Corresponding Source to be so | |
632 available, or (2) arrange to deprive yourself of the benefit of the | |
633 patent license for this particular work, or (3) arrange, in a manner | |
634 consistent with the requirements of this License, to extend the patent | |
635 license to downstream recipients. “Knowingly relying” means you have | |
636 actual knowledge that, but for the patent license, your conveying the | |
637 covered work in a country, or your recipient's use of the covered work | |
638 in a country, would infringe one or more identifiable patents in that | |
639 country that you have reason to believe are valid. | |
640 </p> | |
641 <p>If, pursuant to or in connection with a single transaction or | |
642 arrangement, you convey, or propagate by procuring conveyance of, a | |
643 covered work, and grant a patent license to some of the parties | |
644 receiving the covered work authorizing them to use, propagate, modify | |
645 or convey a specific copy of the covered work, then the patent license | |
646 you grant is automatically extended to all recipients of the covered | |
647 work and works based on it. | |
648 </p> | |
649 <p>A patent license is “discriminatory” if it does not include within the | |
650 scope of its coverage, prohibits the exercise of, or is conditioned on | |
651 the non-exercise of one or more of the rights that are specifically | |
652 granted under this License. You may not convey a covered work if you | |
653 are a party to an arrangement with a third party that is in the | |
654 business of distributing software, under which you make payment to the | |
655 third party based on the extent of your activity of conveying the | |
656 work, and under which the third party grants, to any of the parties | |
657 who would receive the covered work from you, a discriminatory patent | |
658 license (a) in connection with copies of the covered work conveyed by | |
659 you (or copies made from those copies), or (b) primarily for and in | |
660 connection with specific products or compilations that contain the | |
661 covered work, unless you entered into that arrangement, or that patent | |
662 license was granted, prior to 28 March 2007. | |
663 </p> | |
664 <p>Nothing in this License shall be construed as excluding or limiting | |
665 any implied license or other defenses to infringement that may | |
666 otherwise be available to you under applicable patent law. | |
667 </p> | |
668 </li><li> No Surrender of Others' Freedom. | |
669 | |
670 <p>If conditions are imposed on you (whether by court order, agreement or | |
671 otherwise) that contradict the conditions of this License, they do not | |
672 excuse you from the conditions of this License. If you cannot convey | |
673 a covered work so as to satisfy simultaneously your obligations under | |
674 this License and any other pertinent obligations, then as a | |
675 consequence you may not convey it at all. For example, if you agree | |
676 to terms that obligate you to collect a royalty for further conveying | |
677 from those to whom you convey the Program, the only way you could | |
678 satisfy both those terms and this License would be to refrain entirely | |
679 from conveying the Program. | |
680 </p> | |
681 </li><li> Use with the GNU Affero General Public License. | |
682 | |
683 <p>Notwithstanding any other provision of this License, you have | |
684 permission to link or combine any covered work with a work licensed | |
685 under version 3 of the GNU Affero General Public License into a single | |
686 combined work, and to convey the resulting work. The terms of this | |
687 License will continue to apply to the part which is the covered work, | |
688 but the special requirements of the GNU Affero General Public License, | |
689 section 13, concerning interaction through a network will apply to the | |
690 combination as such. | |
691 </p> | |
692 </li><li> Revised Versions of this License. | |
693 | |
694 <p>The Free Software Foundation may publish revised and/or new versions | |
695 of the GNU General Public License from time to time. Such new | |
696 versions will be similar in spirit to the present version, but may | |
697 differ in detail to address new problems or concerns. | |
698 </p> | |
699 <p>Each version is given a distinguishing version number. If the Program | |
700 specifies that a certain numbered version of the GNU General Public | |
701 License “or any later version” applies to it, you have the option of | |
702 following the terms and conditions either of that numbered version or | |
703 of any later version published by the Free Software Foundation. If | |
704 the Program does not specify a version number of the GNU General | |
705 Public License, you may choose any version ever published by the Free | |
706 Software Foundation. | |
707 </p> | |
708 <p>If the Program specifies that a proxy can decide which future versions | |
709 of the GNU General Public License can be used, that proxy's public | |
710 statement of acceptance of a version permanently authorizes you to | |
711 choose that version for the Program. | |
712 </p> | |
713 <p>Later license versions may give you additional or different | |
714 permissions. However, no additional obligations are imposed on any | |
715 author or copyright holder as a result of your choosing to follow a | |
716 later version. | |
717 </p> | |
718 </li><li> Disclaimer of Warranty. | |
719 | |
720 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
721 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
722 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT | |
723 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT | |
724 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR | |
725 A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND | |
726 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE | |
727 DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR | |
728 CORRECTION. | |
729 </p> | |
730 </li><li> Limitation of Liability. | |
731 | |
732 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
733 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR | |
734 CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
735 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES | |
736 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT | |
737 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR | |
738 LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM | |
739 TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER | |
740 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. | |
741 </p> | |
742 </li><li> Interpretation of Sections 15 and 16. | |
743 | |
744 <p>If the disclaimer of warranty and limitation of liability provided | |
745 above cannot be given local legal effect according to their terms, | |
746 reviewing courts shall apply local law that most closely approximates | |
747 an absolute waiver of all civil liability in connection with the | |
748 Program, unless a warranty or assumption of liability accompanies a | |
749 copy of the Program in return for a fee. | |

757 <h2 class="heading"> How to Apply These Terms to Your New Programs </h2> | |
758 | |
759 <p>If you develop a new program, and you want it to be of the greatest | |
760 possible use to the public, the best way to achieve this is to make it | |
761 free software which everyone can redistribute and change under these | |
762 terms. | |
763 </p> | |
764 <p>To do so, attach the following notices to the program. It is safest | |
765 to attach them to the start of each source file to most effectively | |
766 state the exclusion of warranty; and each file should have at least | |
767 the “copyright” line and a pointer to where the full notice is found. | |
768 </p> | |
769 <table><tr><td> </td><td><pre class="smallexample"><var>one line to give the program's name and a brief idea of what it does.</var> | |

772 This program is free software: you can redistribute it and/or modify | |
773 it under the terms of the GNU General Public License as published by | |
774 the Free Software Foundation, either version 3 of the License, or (at | |
775 your option) any later version. | |
776 | |
777 This program is distributed in the hope that it will be useful, but | |
778 WITHOUT ANY WARRANTY; without even the implied warranty of | |
779 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU | |
780 General Public License for more details. | |
781 | |
782 You should have received a copy of the GNU General Public License | |
783 along with this program. If not, see <a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>. | |
784 </pre></td></tr></table> | |
785 | |
786 <p>Also add information on how to contact you by electronic and paper mail. | |
787 </p> | |
788 <p>If the program does terminal interaction, make it output a short | |
789 notice like this when it starts in an interactive mode: | |
790 </p> | |

794 under certain conditions; type ‘<samp>show c</samp>’ for details. | |
795 </pre></td></tr></table> | |
796 | |
797 <p>The hypothetical commands ‘<samp>show w</samp>’ and ‘<samp>show c</samp>’ should show | |
798 the appropriate parts of the General Public License. Of course, your | |
799 program's commands might be different; for a GUI interface, you would | |
800 use an “about box”. | |
801 </p> | |
802 <p>You should also get your employer (if you work as a programmer) or school, | |
803 if any, to sign a “copyright disclaimer” for the program, if necessary. | |
804 For more information on this, and how to apply and follow the GNU GPL, see | |
805 <a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>. | |
806 </p> | |
807 <p>The GNU General Public License does not permit incorporating your | |
808 program into proprietary programs. If your program is a subroutine | |
809 library, you may consider it more useful to permit linking proprietary | |
810 applications with the library. If this is what you want to do, use | |
811 the GNU Lesser General Public License instead of this License. But | |

830 PREAMBLE | |
831 | |
832 <p>The purpose of this License is to make a manual, textbook, or other | |
833 functional and useful document <em>free</em> in the sense of freedom: to | |
834 assure everyone the effective freedom to copy and redistribute it, | |
835 with or without modifying it, either commercially or noncommercially. | |
836 Secondarily, this License preserves for the author and publisher a way | |
837 to get credit for their work, while not being considered responsible | |
838 for modifications made by others. | |
839 </p> | |
840 <p>This License is a kind of “copyleft”, which means that derivative | |
841 works of the document must themselves be free in the same sense. It | |
842 complements the GNU General Public License, which is a copyleft | |
843 license designed for free software. | |
844 </p> | |
845 <p>We have designed this License in order to use it for manuals for free | |
846 software, because free software needs free documentation: a free | |
847 program should come with manuals providing the same freedoms that the | |
848 software does. But this License is not limited to software manuals; | |
849 it can be used for any textual work, regardless of subject matter or | |
850 whether it is published as a printed book. We recommend this License | |
851 principally for works whose purpose is instruction or reference. | |
852 </p> | |
853 </li><li> | |
854 APPLICABILITY AND DEFINITIONS | |
855 | |
856 <p>This License applies to any manual or other work, in any medium, that | |
857 contains a notice placed by the copyright holder saying it can be | |
858 distributed under the terms of this License. Such a notice grants a | |
859 world-wide, royalty-free license, unlimited in duration, to use that | |
860 work under the conditions stated herein. The “Document”, below, | |
861 refers to any such manual or work. Any member of the public is a | |
862 licensee, and is addressed as “you”. You accept the license if you | |
863 copy, modify or distribute the work in a way requiring permission | |
864 under copyright law. | |
865 </p> | |
866 <p>A “Modified Version” of the Document means any work containing the | |
867 Document or a portion of it, either copied verbatim, or with | |
868 modifications and/or translated into another language. | |
869 </p> | |
870 <p>A “Secondary Section” is a named appendix or a front-matter section | |
871 of the Document that deals exclusively with the relationship of the | |
872 publishers or authors of the Document to the Document's overall | |
873 subject (or to related matters) and contains nothing that could fall | |
874 directly within that overall subject. (Thus, if the Document is in | |
875 part a textbook of mathematics, a Secondary Section may not explain | |
876 any mathematics.) The relationship could be a matter of historical | |
877 connection with the subject or with related matters, or of legal, | |
878 commercial, philosophical, ethical or political position regarding | |
879 them. | |
880 </p> | |
881 <p>The “Invariant Sections” are certain Secondary Sections whose titles | |
882 are designated, as being those of Invariant Sections, in the notice | |
883 that says that the Document is released under this License. If a | |
884 section does not fit the above definition of Secondary then it is not | |
885 allowed to be designated as Invariant. The Document may contain zero | |
886 Invariant Sections. If the Document does not identify any Invariant | |
887 Sections then there are none. | |
888 </p> | |
889 <p>The “Cover Texts” are certain short passages of text that are listed, | |
890 as Front-Cover Texts or Back-Cover Texts, in the notice that says that | |
891 the Document is released under this License. A Front-Cover Text may | |
892 be at most 5 words, and a Back-Cover Text may be at most 25 words. | |
893 </p> | |
894 <p>A “Transparent” copy of the Document means a machine-readable copy, | |
895 represented in a format whose specification is available to the | |
896 general public, that is suitable for revising the document | |
897 straightforwardly with generic text editors or (for images composed of | |
898 pixels) generic paint programs or (for drawings) some widely available | |
899 drawing editor, and that is suitable for input to text formatters or | |
900 for automatic translation to a variety of formats suitable for input | |
901 to text formatters. A copy made in an otherwise Transparent file | |
902 format whose markup, or absence of markup, has been arranged to thwart | |
903 or discourage subsequent modification by readers is not Transparent. | |
904 An image format is not Transparent if used for any substantial amount | |
905 of text. A copy that is not “Transparent” is called “Opaque”. | |
906 </p> | |
907 <p>Examples of suitable formats for Transparent copies include plain | |
908 ASCII without markup, Texinfo input format, LaTeX input | |
909 format, SGML or XML using a publicly available | |
910 DTD, and standard-conforming simple HTML, | |
911 PostScript or PDF designed for human modification. Examples | |
912 of transparent image formats include PNG, XCF and | |
913 JPG. Opaque formats include proprietary formats that can be | |
914 read and edited only by proprietary word processors, SGML or | |
915 XML for which the DTD and/or processing tools are | |
916 not generally available, and the machine-generated HTML, | |
917 PostScript or PDF produced by some word processors for | |
918 output purposes only. | |
919 </p> | |
920 <p>The “Title Page” means, for a printed book, the title page itself, | |
921 plus such following pages as are needed to hold, legibly, the material | |
922 this License requires to appear in the title page. For works in | |
923 formats which do not have any title page as such, “Title Page” means | |
924 the text near the most prominent appearance of the work's title, | |
925 preceding the beginning of the body of the text. | |
926 </p> | |
927 <p>The “publisher” means any person or entity that distributes copies | |
928 of the Document to the public. | |
929 </p> | |
930 <p>A section “Entitled XYZ” means a named subunit of the Document whose | |
931 title either is precisely XYZ or contains XYZ in parentheses following | |
932 text that translates XYZ in another language. (Here XYZ stands for a | |
933 specific section name mentioned below, such as “Acknowledgements”, | |
934 “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” | |
935 of such a section when you modify the Document means that it remains a | |
936 section “Entitled XYZ” according to this definition. | |
937 </p> | |
938 <p>The Document may include Warranty Disclaimers next to the notice which | |
939 states that this License applies to the Document. These Warranty | |
940 Disclaimers are considered to be included by reference in this | |
941 License, but only as regards disclaiming warranties: any other | |
942 implication that these Warranty Disclaimers may have is void and has | |
943 no effect on the meaning of this License. | |
944 </p> | |
945 </li><li> | |
946 VERBATIM COPYING | |
947 | |
948 <p>You may copy and distribute the Document in any medium, either | |
949 commercially or noncommercially, provided that this License, the | |
950 copyright notices, and the license notice saying this License applies | |
951 to the Document are reproduced in all copies, and that you add no other | |
952 conditions whatsoever to those of this License. You may not use | |
953 technical measures to obstruct or control the reading or further | |
954 copying of the copies you make or distribute. However, you may accept | |
955 compensation in exchange for copies. If you distribute a large enough | |
956 number of copies you must also follow the conditions in section 3. | |
957 </p> | |
958 <p>You may also lend copies, under the same conditions stated above, and | |
959 you may publicly display copies. | |
960 </p> | |
961 </li><li> | |
962 COPYING IN QUANTITY | |
963 | |
964 <p>If you publish printed copies (or copies in media that commonly have | |
965 printed covers) of the Document, numbering more than 100, and the | |
966 Document's license notice requires Cover Texts, you must enclose the | |
967 copies in covers that carry, clearly and legibly, all these Cover | |
968 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on | |
969 the back cover. Both covers must also clearly and legibly identify | |
970 you as the publisher of these copies. The front cover must present | |
971 the full title with all words of the title equally prominent and | |
972 visible. You may add other material on the covers in addition. | |
973 Copying with changes limited to the covers, as long as they preserve | |
974 the title of the Document and satisfy these conditions, can be treated | |
975 as verbatim copying in other respects. | |
976 </p> | |
977 <p>If the required texts for either cover are too voluminous to fit | |
978 legibly, you should put the first ones listed (as many as fit | |
979 reasonably) on the actual cover, and continue the rest onto adjacent | |
980 pages. | |
981 </p> | |
982 <p>If you publish or distribute Opaque copies of the Document numbering | |
983 more than 100, you must either include a machine-readable Transparent | |
984 copy along with each Opaque copy, or state in or with each Opaque copy | |
985 a computer-network location from which the general network-using | |
986 public has access to download using public-standard network protocols | |
987 a complete Transparent copy of the Document, free of added material. | |
988 If you use the latter option, you must take reasonably prudent steps, | |
989 when you begin distribution of Opaque copies in quantity, to ensure | |
990 that this Transparent copy will remain thus accessible at the stated | |
991 location until at least one year after the last time you distribute an | |
992 Opaque copy (directly or through your agents or retailers) of that | |
993 edition to the public. | |
994 </p> | |
995 <p>It is requested, but not required, that you contact the authors of the | |
996 Document well before redistributing any large number of copies, to give | |
997 them a chance to provide you with an updated version of the Document. | |
998 </p> | |
999 </li><li> | |
1000 MODIFICATIONS | |
1001 | |
1002 <p>You may copy and distribute a Modified Version of the Document under | |
1003 the conditions of sections 2 and 3 above, provided that you release | |
1004 the Modified Version under precisely this License, with the Modified | |
1005 Version filling the role of the Document, thus licensing distribution | |
1006 and modification of the Modified Version to whoever possesses a copy | |
1007 of it. In addition, you must do these things in the Modified Version: | |
1008 </p> | |
1009 <ol> | |
1010 <li> | |
1011 Use in the Title Page (and on the covers, if any) a title distinct | |
1012 from that of the Document, and from those of previous versions | |
1013 (which should, if there were any, be listed in the History section | |
1014 of the Document). You may use the same title as a previous version | |
1015 if the original publisher of that version gives permission. | |
1016 | |
1017 </li><li> | |
1018 List on the Title Page, as authors, one or more persons or entities | |
1019 responsible for authorship of the modifications in the Modified | |
1020 Version, together with at least five of the principal authors of the | |
1021 Document (all of its principal authors, if it has fewer than five), | |
1022 unless they release you from this requirement. | |
1023 | |
1024 </li><li> | |
1025 State on the Title page the name of the publisher of the | |
1026 Modified Version, as the publisher. | |
1027 | |
1028 </li><li> | |
1029 Preserve all the copyright notices of the Document. | |
1030 | |
1031 </li><li> | |
1032 Add an appropriate copyright notice for your modifications | |
1033 adjacent to the other copyright notices. | |
1034 | |
1035 </li><li> | |
1036 Include, immediately after the copyright notices, a license notice | |
1037 giving the public permission to use the Modified Version under the | |
1038 terms of this License, in the form shown in the Addendum below. | |
1039 | |
1040 </li><li> | |
1041 Preserve in that license notice the full lists of Invariant Sections | |
1042 and required Cover Texts given in the Document's license notice. | |
1043 | |
1044 </li><li> | |
1045 Include an unaltered copy of this License. | |
1046 | |
1047 </li><li> | |
1048 Preserve the section Entitled “History”, Preserve its Title, and add | |
1049 to it an item stating at least the title, year, new authors, and | |
1050 publisher of the Modified Version as given on the Title Page. If | |
1051 there is no section Entitled “History” in the Document, create one | |
1052 stating the title, year, authors, and publisher of the Document as | |
1053 given on its Title Page, then add an item describing the Modified | |
1054 Version as stated in the previous sentence. | |
1055 | |
1056 </li><li> | |
1057 Preserve the network location, if any, given in the Document for | |
1058 public access to a Transparent copy of the Document, and likewise | |
1059 the network locations given in the Document for previous versions | |
1060 it was based on. These may be placed in the “History” section. | |
1061 You may omit a network location for a work that was published at | |
1062 least four years before the Document itself, or if the original | |
1063 publisher of the version it refers to gives permission. | |
1064 | |
1065 </li><li> | |
1066 For any section Entitled “Acknowledgements” or “Dedications”, Preserve | |
1067 the Title of the section, and preserve in the section all the | |
1068 substance and tone of each of the contributor acknowledgements and/or | |
1069 dedications given therein. | |
1070 | |
1071 </li><li> | |
1072 Preserve all the Invariant Sections of the Document, | |
1073 unaltered in their text and in their titles. Section numbers | |
1074 or the equivalent are not considered part of the section titles. | |
1075 | |
1076 </li><li> | |
1077 Delete any section Entitled “Endorsements”. Such a section | |
1078 may not be included in the Modified Version. | |
1079 | |
1080 </li><li> | |
1081 Do not retitle any existing section to be Entitled “Endorsements” or | |
1082 to conflict in title with any Invariant Section. | |
1083 | |
1084 </li><li> | |
1085 Preserve any Warranty Disclaimers. | |
1086 </li></ol> | |
1087 | |
1088 <p>If the Modified Version includes new front-matter sections or | |
1089 appendices that qualify as Secondary Sections and contain no material | |
1090 copied from the Document, you may at your option designate some or all | |
1091 of these sections as invariant. To do this, add their titles to the | |
1092 list of Invariant Sections in the Modified Version's license notice. | |
1093 These titles must be distinct from any other section titles. | |
1094 </p> | |
1095 <p>You may add a section Entitled “Endorsements”, provided it contains | |
1096 nothing but endorsements of your Modified Version by various | |
1097 parties—for example, statements of peer review or that the text has | |
1098 been approved by an organization as the authoritative definition of a | |
1099 standard. | |
1100 </p> | |
1101 <p>You may add a passage of up to five words as a Front-Cover Text, and a | |
1102 passage of up to 25 words as a Back-Cover Text, to the end of the list | |
1103 of Cover Texts in the Modified Version. Only one passage of | |
1104 Front-Cover Text and one of Back-Cover Text may be added by (or | |
1105 through arrangements made by) any one entity. If the Document already | |
1106 includes a cover text for the same cover, previously added by you or | |
1107 by arrangement made by the same entity you are acting on behalf of, | |
1108 you may not add another; but you may replace the old one, on explicit | |
1109 permission from the previous publisher that added the old one. | |
1110 </p> | |
1111 <p>The author(s) and publisher(s) of the Document do not by this License | |
1112 give permission to use their names for publicity for or to assert or | |
1113 imply endorsement of any Modified Version. | |
1114 </p> | |
1115 </li><li> | |
1116 COMBINING DOCUMENTS | |
1117 | |
1118 <p>You may combine the Document with other documents released under this | |
1119 License, under the terms defined in section 4 above for modified | |
1120 versions, provided that you include in the combination all of the | |
1121 Invariant Sections of all of the original documents, unmodified, and | |
1122 list them all as Invariant Sections of your combined work in its | |
1123 license notice, and that you preserve all their Warranty Disclaimers. | |
1124 </p> | |
1125 <p>The combined work need only contain one copy of this License, and | |
1126 multiple identical Invariant Sections may be replaced with a single | |
1127 copy. If there are multiple Invariant Sections with the same name but | |
1128 different contents, make the title of each such section unique by | |
1129 adding at the end of it, in parentheses, the name of the original | |
1130 author or publisher of that section if known, or else a unique number. | |
1131 Make the same adjustment to the section titles in the list of | |
1132 Invariant Sections in the license notice of the combined work. | |
1133 </p> | |
1134 <p>In the combination, you must combine any sections Entitled “History” | |
1135 in the various original documents, forming one section Entitled | |
1136 “History”; likewise combine any sections Entitled “Acknowledgements”, | |
1137 and any sections Entitled “Dedications”. You must delete all | |
1138 sections Entitled “Endorsements.” | |
1139 </p> | |
1140 </li><li> | |
1141 COLLECTIONS OF DOCUMENTS | |
1142 | |
1143 <p>You may make a collection consisting of the Document and other documents | |
1144 released under this License, and replace the individual copies of this | |
1145 License in the various documents with a single copy that is included in | |
1146 the collection, provided that you follow the rules of this License for | |
1147 verbatim copying of each of the documents in all other respects. | |
1148 </p> | |
1149 <p>You may extract a single document from such a collection, and distribute | |
1150 it individually under this License, provided you insert a copy of this | |
1151 License into the extracted document, and follow this License in all | |
1152 other respects regarding verbatim copying of that document. | |
1153 </p> | |
1154 </li><li> | |
1155 AGGREGATION WITH INDEPENDENT WORKS | |
1156 | |
1157 <p>A compilation of the Document or its derivatives with other separate | |
1158 and independent documents or works, in or on a volume of a storage or | |
1159 distribution medium, is called an “aggregate” if the copyright | |
1160 resulting from the compilation is not used to limit the legal rights | |
1161 of the compilation's users beyond what the individual works permit. | |
1162 When the Document is included in an aggregate, this License does not | |
1163 apply to the other works in the aggregate which are not themselves | |
1164 derivative works of the Document. | |
1165 </p> | |
1166 <p>If the Cover Text requirement of section 3 is applicable to these | |
1167 copies of the Document, then if the Document is less than one half of | |
1168 the entire aggregate, the Document's Cover Texts may be placed on | |
1169 covers that bracket the Document within the aggregate, or the | |
1170 electronic equivalent of covers if the Document is in electronic form. | |
1171 Otherwise they must appear on printed covers that bracket the whole | |
1172 aggregate. | |
1173 </p> | |
1174 </li><li> | |
1175 TRANSLATION | |
1176 | |
1177 <p>Translation is considered a kind of modification, so you may | |
1178 distribute translations of the Document under the terms of section 4. | |
1179 Replacing Invariant Sections with translations requires special | |
1180 permission from their copyright holders, but you may include | |
1181 translations of some or all Invariant Sections in addition to the | |
1182 original versions of these Invariant Sections. You may include a | |
1183 translation of this License, and all the license notices in the | |
1184 Document, and any Warranty Disclaimers, provided that you also include | |
1185 the original English version of this License and the original versions | |
1186 of those notices and disclaimers. In case of a disagreement between | |
1187 the translation and the original version of this License or a notice | |
1188 or disclaimer, the original version will prevail. | |
1189 </p> | |
1190 <p>If a section in the Document is Entitled “Acknowledgements”, | |
1191 “Dedications”, or “History”, the requirement (section 4) to Preserve | |
1192 its Title (section 1) will typically require changing the actual | |
1193 title. | |
1194 </p> | |
1195 </li><li> | |
1196 TERMINATION | |
1197 | |
1198 <p>You may not copy, modify, sublicense, or distribute the Document | |
1199 except as expressly provided under this License. Any attempt | |
1200 otherwise to copy, modify, sublicense, or distribute it is void, and | |
1201 will automatically terminate your rights under this License. | |
1202 </p> | |
1203 <p>However, if you cease all violation of this License, then your license | |
1204 from a particular copyright holder is reinstated (a) provisionally, | |
1205 unless and until the copyright holder explicitly and finally | |
1206 terminates your license, and (b) permanently, if the copyright holder | |
1207 fails to notify you of the violation by some reasonable means prior to | |
1208 60 days after the cessation. | |
1209 </p> | |
1210 <p>Moreover, your license from a particular copyright holder is | |
1211 reinstated permanently if the copyright holder notifies you of the | |
1212 violation by some reasonable means, this is the first time you have | |
1213 received notice of violation of this License (for any work) from that | |
1214 copyright holder, and you cure the violation prior to 30 days after | |
1215 your receipt of the notice. | |
1216 </p> | |
1217 <p>Termination of your rights under this section does not terminate the | |
1218 licenses of parties who have received copies or rights from you under | |
1219 this License. If your rights have been terminated and not permanently | |
1220 reinstated, receipt of a copy of some or all of the same material does | |
1221 not give you any rights to use it. | |
1222 </p> | |
1223 </li><li> | |
1224 FUTURE REVISIONS OF THIS LICENSE | |
1225 | |
1226 <p>The Free Software Foundation may publish new, revised versions | |
1227 of the GNU Free Documentation License from time to time. Such new | |
1228 versions will be similar in spirit to the present version, but may | |
1229 differ in detail to address new problems or concerns. See | |
1230 <a href="https://www.gnu.org/copyleft/">https://www.gnu.org/copyleft/</a>. | |
1231 </p> | |
1232 <p>Each version of the License is given a distinguishing version number. | |
1233 If the Document specifies that a particular numbered version of this | |
1234 License “or any later version” applies to it, you have the option of | |
1235 following the terms and conditions either of that specified version or | |
1236 of any later version that has been published (not as a draft) by the | |
1237 Free Software Foundation. If the Document does not specify a version | |
1238 number of this License, you may choose any version ever published (not | |
1239 as a draft) by the Free Software Foundation. If the Document | |
1240 specifies that a proxy can decide which future versions of this | |
1241 License can be used, that proxy's public statement of acceptance of a | |
1242 version permanently authorizes you to choose that version for the | |
1243 Document. | |
1244 </p> | |
1245 </li><li> | |
1246 RELICENSING | |
1247 | |
1248 <p>“Massive Multiauthor Collaboration Site” (or “MMC Site”) means any | |
1249 World Wide Web server that publishes copyrightable works and also | |
1250 provides prominent facilities for anybody to edit those works. A | |
1251 public wiki that anybody can edit is an example of such a server. A | |
1252 “Massive Multiauthor Collaboration” (or “MMC”) contained in the | |
1253 site means any set of copyrightable works thus published on the MMC | |
1254 site. | |
1255 </p> | |
1256 <p>“CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 | |
1257 license published by Creative Commons Corporation, a not-for-profit | |
1258 corporation with a principal place of business in San Francisco, | |
1259 California, as well as future copyleft versions of that license | |
1260 published by that same organization. | |
1261 </p> | |
1262 <p>“Incorporate” means to publish or republish a Document, in whole or | |
1263 in part, as part of another Document. | |
1264 </p> | |
1265 <p>An MMC is “eligible for relicensing” if it is licensed under this | |
1266 License, and if all works that were first published under this License | |
1267 somewhere other than this MMC, and subsequently incorporated in whole | |
1268 or in part into the MMC, (1) had no cover texts or invariant sections, | |
1269 and (2) were thus incorporated prior to November 1, 2008. | |
1270 </p> | |
1271 <p>The operator of an MMC Site may republish an MMC contained in the site | |
1272 under CC-BY-SA on the same site at any time before August 1, 2009, | |
1273 provided the MMC is eligible for relicensing. | |

1280 | |
1281 <p>To use this License in a document you have written, include a copy of | |
