126 standard defined by a recognized standards body, or, in the case of |
119 a warranty) and that users may redistribute the program under |

135 implementation is available to the public in source code form. A |
128 themselves, then this License, and its terms, do not apply to those |
136 "Major Component", in this context, means a major essential component |
129 sections when you distribute them as separate works. But when you |
137 (kernel, window system, and so on) of the specific operating system |
130 distribute the same sections as part of a whole which is a work based |
138 (if any) on which the executable work runs, or a compiler used to |

140 |
133 entire whole, and thus to each and every part regardless of who wrote it. |
141 The "Corresponding Source" for a work in object code form means all |
134 |
142 the source code needed to generate, install, and (for an executable |
135 Thus, it is not the intent of this section to claim rights or contest |
143 work) run the object code and to modify the work, including scripts to |
136 your rights to work written entirely by you; rather, the intent is to |
144 control those activities. However, it does not include the work's |
137 exercise the right to control the distribution of derivative or |

144 |
152 subprograms and other parts of the work. |
145 3. You may copy and distribute the Program (or a work based on it, |
153 |
146 under Section 2) in object code or executable form under the terms of |
154 The Corresponding Source need not include anything that users |
147 Sections 1 and 2 above provided that you also do one of the following: |

165 conditions are met. This License explicitly affirms your unlimited |
158 customarily used for software interchange; or, |

167 covered work is covered by this License only if the output, given its |

173 in force. You may convey covered works to others for the sole purpose |
166 The source code for a work means the preferred form of the work for |
174 of having them make modifications exclusively for you, or provide you |
167 making modifications to it. For an executable work, complete source |
175 with facilities for running those works, provided that you comply with |
168 code means all the source code for all modules it contains, plus any |
176 the terms of this License in conveying all material for which you do |
169 associated interface definition files, plus the scripts used to |
177 not control copyright. Those thus making or running the covered works |
170 control compilation and installation of the executable. However, as a |

183 the conditions stated below. Sublicensing is not allowed; section 10 |

177 If distribution of executable or object code is made by offering |
185 |
178 access to copy from a designated place, then offering equivalent |
186 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
179 access to copy the source code from the same place counts as |
187 |
180 distribution of the source code, even though third parties are not |
188 No covered work shall be deemed part of an effective technological |
181 compelled to copy the source along with the object code. |
189 measure under any applicable law fulfilling obligations under article |
182 |
190 11 of the WIPO copyright treaty adopted on 20 December 1996, or |
183 4. You may not copy, modify, sublicense, or distribute the Program |
191 similar laws prohibiting or restricting circumvention of such |
184 except as expressly provided under this License. Any attempt |
192 measures. |
185 otherwise to copy, modify, sublicense or distribute the Program is |
193 |
186 void, and will automatically terminate your rights under this License. |
194 When you convey a covered work, you waive any legal power to forbid |
187 However, parties who have received copies, or rights, from you under |
195 circumvention of technological measures to the extent such circumvention |
188 this License will not have their licenses terminated so long as such |
196 is effected by exercising rights under this License with respect to |
189 parties remain in full compliance. |
197 the covered work, and you disclaim any intention to limit operation or |
190 |
198 modification of the work as a means of enforcing, against the work's |
191 5. You are not required to accept this License, since you have not |
199 users, your or third parties' legal rights to forbid circumvention of |
192 signed it. However, nothing else grants you permission to modify or |
200 technological measures. |
193 distribute the Program or its derivative works. These actions are |
201 |
194 prohibited by law if you do not accept this License. Therefore, by |
202 4. Conveying Verbatim Copies. |
195 modifying or distributing the Program (or any work based on the |
203 |
196 Program), you indicate your acceptance of this License to do so, and |
204 You may convey verbatim copies of the Program's source code as you |
197 all its terms and conditions for copying, distributing or modifying |
205 receive it, in any medium, provided that you conspicuously and |
198 the Program or works based on it. |
206 appropriately publish on each copy an appropriate copyright notice; |
199 |
207 keep intact all notices stating that this License and any |
200 6. Each time you redistribute the Program (or any work based on the |
208 non-permissive terms added in accord with section 7 apply to the code; |
201 Program), the recipient automatically receives a license from the |
209 keep intact all notices of the absence of any warranty; and give all |
202 original licensor to copy, distribute or modify the Program subject to |
210 recipients a copy of this License along with the Program. |
203 these terms and conditions. You may not impose any further |
211 |
204 restrictions on the recipients' exercise of the rights granted herein. |
212 You may charge any price or no price for each copy that you convey, |
205 You are not responsible for enforcing compliance by third parties to |
213 and you may offer support or warranty protection for a fee. |
|
214 |
|
215 5. Conveying Modified Source Versions. |
|
216 |
|
217 You may convey a work based on the Program, or the modifications to |
|
218 produce it from the Program, in the form of source code under the |
|
219 terms of section 4, provided that you also meet all of these conditions: |
|
220 |
|
221 a) The work must carry prominent notices stating that you modified |
|
222 it, and giving a relevant date. |
|
223 |
|
224 b) The work must carry prominent notices stating that it is |
|
225 released under this License and any conditions added under section |
|
226 7. This requirement modifies the requirement in section 4 to |
|
227 "keep intact all notices". |
|
228 |
|
229 c) You must license the entire work, as a whole, under this |
|
230 License to anyone who comes into possession of a copy. This |
|
231 License will therefore apply, along with any applicable section 7 |
|
232 additional terms, to the whole of the work, and all its parts, |
|
233 regardless of how they are packaged. This License gives no |
|
234 permission to license the work in any other way, but it does not |
|
235 invalidate such permission if you have separately received it. |
|
236 |
|
237 d) If the work has interactive user interfaces, each must display |
|
238 Appropriate Legal Notices; however, if the Program has interactive |
|
239 interfaces that do not display Appropriate Legal Notices, your |
|
240 work need not make them do so. |
|
241 |
|
242 A compilation of a covered work with other separate and independent |
|
243 works, which are not by their nature extensions of the covered work, |
|
244 and which are not combined with it such as to form a larger program, |
|
245 in or on a volume of a storage or distribution medium, is called an |
|
246 "aggregate" if the compilation and its resulting copyright are not |
|
247 used to limit the access or legal rights of the compilation's users |
|
248 beyond what the individual works permit. Inclusion of a covered work |
|
249 in an aggregate does not cause this License to apply to the other |
|
250 parts of the aggregate. |
|
251 |
|
252 6. Conveying Non-Source Forms. |
|
253 |
|
254 You may convey a covered work in object code form under the terms |
|
255 of sections 4 and 5, provided that you also convey the |
|
256 machine-readable Corresponding Source under the terms of this License, |
|
257 in one of these ways: |
|
258 |
|
259 a) Convey the object code in, or embodied in, a physical product |
|
260 (including a physical distribution medium), accompanied by the |
|
261 Corresponding Source fixed on a durable physical medium |
|
262 customarily used for software interchange. |
|
263 |
|
264 b) Convey the object code in, or embodied in, a physical product |
|
265 (including a physical distribution medium), accompanied by a |
|
266 written offer, valid for at least three years and valid for as |
|
267 long as you offer spare parts or customer support for that product |
|
268 model, to give anyone who possesses the object code either (1) a |
|
269 copy of the Corresponding Source for all the software in the |
|
270 product that is covered by this License, on a durable physical |
|
271 medium customarily used for software interchange, for a price no |
|
272 more than your reasonable cost of physically performing this |
|
273 conveying of source, or (2) access to copy the |
|
274 Corresponding Source from a network server at no charge. |
|
275 |
|
276 c) Convey individual copies of the object code with a copy of the |
|
277 written offer to provide the Corresponding Source. This |
|
278 alternative is allowed only occasionally and noncommercially, and |
|
279 only if you received the object code with such an offer, in accord |
|
280 with subsection 6b. |
|
281 |
|
282 d) Convey the object code by offering access from a designated |
|
283 place (gratis or for a charge), and offer equivalent access to the |
|
284 Corresponding Source in the same way through the same place at no |
|
285 further charge. You need not require recipients to copy the |
|
286 Corresponding Source along with the object code. If the place to |
|
287 copy the object code is a network server, the Corresponding Source |
|
288 may be on a different server (operated by you or a third party) |
|
289 that supports equivalent copying facilities, provided you maintain |
|
290 clear directions next to the object code saying where to find the |
|
291 Corresponding Source. Regardless of what server hosts the |
|
292 Corresponding Source, you remain obligated to ensure that it is |
|
293 available for as long as needed to satisfy these requirements. |
|
294 |
|
295 e) Convey the object code using peer-to-peer transmission, provided |
|
296 you inform other peers where the object code and Corresponding |
|
297 Source of the work are being offered to the general public at no |
|
298 charge under subsection 6d. |
|
299 |
|
300 A separable portion of the object code, whose source code is excluded |
|
301 from the Corresponding Source as a System Library, need not be |
|
302 included in conveying the object code work. |
|
303 |
|
304 A "User Product" is either (1) a "consumer product", which means any |
|
305 tangible personal property which is normally used for personal, family, |
|
306 or household purposes, or (2) anything designed or sold for incorporation |
|
307 into a dwelling. In determining whether a product is a consumer product, |
|
308 doubtful cases shall be resolved in favor of coverage. For a particular |
|
309 product received by a particular user, "normally used" refers to a |
|
310 typical or common use of that class of product, regardless of the status |
|
311 of the particular user or of the way in which the particular user |
|
312 actually uses, or expects or is expected to use, the product. A product |
|
313 is a consumer product regardless of whether the product has substantial |
|
314 commercial, industrial or non-consumer uses, unless such uses represent |
|
315 the only significant mode of use of the product. |
|
316 |
|
317 "Installation Information" for a User Product means any methods, |
|
318 procedures, authorization keys, or other information required to install |
|
319 and execute modified versions of a covered work in that User Product from |
|
320 a modified version of its Corresponding Source. The information must |
|
321 suffice to ensure that the continued functioning of the modified object |
|
322 code is in no case prevented or interfered with solely because |
|
323 modification has been made. |
|
324 |
|
325 If you convey an object code work under this section in, or with, or |
|
326 specifically for use in, a User Product, and the conveying occurs as |
|
327 part of a transaction in which the right of possession and use of the |
|
328 User Product is transferred to the recipient in perpetuity or for a |
|
329 fixed term (regardless of how the transaction is characterized), the |
|
330 Corresponding Source conveyed under this section must be accompanied |
|
331 by the Installation Information. But this requirement does not apply |
|
332 if neither you nor any third party retains the ability to install |
|
333 modified object code on the User Product (for example, the work has |
|
334 been installed in ROM). |
|
335 |
|
336 The requirement to provide Installation Information does not include a |
|
337 requirement to continue to provide support service, warranty, or updates |
|
338 for a work that has been modified or installed by the recipient, or for |
|
339 the User Product in which it has been modified or installed. Access to a |
|
340 network may be denied when the modification itself materially and |
|
341 adversely affects the operation of the network or violates the rules and |
|
342 protocols for communication across the network. |
|
343 |
|
344 Corresponding Source conveyed, and Installation Information provided, |
|
345 in accord with this section must be in a format that is publicly |
|
346 documented (and with an implementation available to the public in |
|
347 source code form), and must require no special password or key for |
|
348 unpacking, reading or copying. |
|
349 |
|
350 7. Additional Terms. |
|
351 |
|
352 "Additional permissions" are terms that supplement the terms of this |
|
353 License by making exceptions from one or more of its conditions. |
|
354 Additional permissions that are applicable to the entire Program shall |
|
355 be treated as though they were included in this License, to the extent |
|
356 that they are valid under applicable law. If additional permissions |
|
357 apply only to part of the Program, that part may be used separately |
|
358 under those permissions, but the entire Program remains governed by |
|
359 this License without regard to the additional permissions. |
|
360 |
|
361 When you convey a copy of a covered work, you may at your option |
|
362 remove any additional permissions from that copy, or from any part of |
|
363 it. (Additional permissions may be written to require their own |
|
364 removal in certain cases when you modify the work.) You may place |
|
365 additional permissions on material, added by you to a covered work, |
|
366 for which you have or can give appropriate copyright permission. |
|
367 |
|
368 Notwithstanding any other provision of this License, for material you |
|
369 add to a covered work, you may (if authorized by the copyright holders of |
|
370 that material) supplement the terms of this License with terms: |
|
371 |
|
372 a) Disclaiming warranty or limiting liability differently from the |
|
373 terms of sections 15 and 16 of this License; or |
|
374 |
|
375 b) Requiring preservation of specified reasonable legal notices or |
|
376 author attributions in that material or in the Appropriate Legal |
|
377 Notices displayed by works containing it; or |
|
378 |
|
379 c) Prohibiting misrepresentation of the origin of that material, or |
|
380 requiring that modified versions of such material be marked in |
|
381 reasonable ways as different from the original version; or |
|
382 |
|
383 d) Limiting the use for publicity purposes of names of licensors or |
|
384 authors of the material; or |
|
385 |
|
386 e) Declining to grant rights under trademark law for use of some |
|
387 trade names, trademarks, or service marks; or |
|
388 |
|
389 f) Requiring indemnification of licensors and authors of that |
|
390 material by anyone who conveys the material (or modified versions of |
|
391 it) with contractual assumptions of liability to the recipient, for |
|
392 any liability that these contractual assumptions directly impose on |
|
393 those licensors and authors. |
|
394 |
|
395 All other non-permissive additional terms are considered "further |
|
396 restrictions" within the meaning of section 10. If the Program as you |
|
397 received it, or any part of it, contains a notice stating that it is |
|
398 governed by this License along with a term that is a further |
|
399 restriction, you may remove that term. If a license document contains |
|
400 a further restriction but permits relicensing or conveying under this |
|
401 License, you may add to a covered work material governed by the terms |
|
402 of that license document, provided that the further restriction does |
|
403 not survive such relicensing or conveying. |
|
404 |
|
405 If you add terms to a covered work in accord with this section, you |
|
406 must place, in the relevant source files, a statement of the |
|
407 additional terms that apply to those files, or a notice indicating |
|
408 where to find the applicable terms. |
|
409 |
|
410 Additional terms, permissive or non-permissive, may be stated in the |
|
411 form of a separately written license, or stated as exceptions; |
|
412 the above requirements apply either way. |
|
413 |
|
414 8. Termination. |
|
415 |
|
416 You may not propagate or modify a covered work except as expressly |
|
417 provided under this License. Any attempt otherwise to propagate or |
|
418 modify it is void, and will automatically terminate your rights under |
|
419 this License (including any patent licenses granted under the third |
|
420 paragraph of section 11). |
|
421 |
|
422 However, if you cease all violation of this License, then your |
|
423 license from a particular copyright holder is reinstated (a) |
|
424 provisionally, unless and until the copyright holder explicitly and |
|
425 finally terminates your license, and (b) permanently, if the copyright |
|
426 holder fails to notify you of the violation by some reasonable means |
|
427 prior to 60 days after the cessation. |
|
428 |
|
429 Moreover, your license from a particular copyright holder is |
|
430 reinstated permanently if the copyright holder notifies you of the |
|
431 violation by some reasonable means, this is the first time you have |
|
432 received notice of violation of this License (for any work) from that |
|
433 copyright holder, and you cure the violation prior to 30 days after |
|
434 your receipt of the notice. |
|
435 |
|
436 Termination of your rights under this section does not terminate the |
|
437 licenses of parties who have received copies or rights from you under |
|
438 this License. If your rights have been terminated and not permanently |
|
439 reinstated, you do not qualify to receive new licenses for the same |
|
440 material under section 10. |
|
441 |
|
442 9. Acceptance Not Required for Having Copies. |
|
443 |
|
444 You are not required to accept this License in order to receive or |
|
445 run a copy of the Program. Ancillary propagation of a covered work |
|
446 occurring solely as a consequence of using peer-to-peer transmission |
|
447 to receive a copy likewise does not require acceptance. However, |
|
448 nothing other than this License grants you permission to propagate or |
|
449 modify any covered work. These actions infringe copyright if you do |
|
450 not accept this License. Therefore, by modifying or propagating a |
|
451 covered work, you indicate your acceptance of this License to do so. |
|
452 |
|
453 10. Automatic Licensing of Downstream Recipients. |
|
454 |
|
455 Each time you convey a covered work, the recipient automatically |
|
456 receives a license from the original licensors, to run, modify and |
|
457 propagate that work, subject to this License. You are not responsible |
|
458 for enforcing compliance by third parties with this License. |
|
459 |
|
460 An "entity transaction" is a transaction transferring control of an |
|
461 organization, or substantially all assets of one, or subdividing an |
|
462 organization, or merging organizations. If propagation of a covered |
|
463 work results from an entity transaction, each party to that |
|
464 transaction who receives a copy of the work also receives whatever |
|
465 licenses to the work the party's predecessor in interest had or could |
|
466 give under the previous paragraph, plus a right to possession of the |
|
467 Corresponding Source of the work from the predecessor in interest, if |
|
468 the predecessor has it or can get it with reasonable efforts. |
|
469 |
|
470 You may not impose any further restrictions on the exercise of the |
|
471 rights granted or affirmed under this License. For example, you may |
|
472 not impose a license fee, royalty, or other charge for exercise of |
|
473 rights granted under this License, and you may not initiate litigation |
|
474 (including a cross-claim or counterclaim in a lawsuit) alleging that |
|
475 any patent claim is infringed by making, using, selling, offering for |
|
476 sale, or importing the Program or any portion of it. |
|
477 |
|
478 11. Patents. |
|
479 |
|
480 A "contributor" is a copyright holder who authorizes use under this |
|
481 License of the Program or a work on which the Program is based. The |
|
482 work thus licensed is called the contributor's "contributor version". |
|
483 |
|
484 A contributor's "essential patent claims" are all patent claims |
|
485 owned or controlled by the contributor, whether already acquired or |
|
486 hereafter acquired, that would be infringed by some manner, permitted |
|
487 by this License, of making, using, or selling its contributor version, |
|
488 but do not include claims that would be infringed only as a |
|
489 consequence of further modification of the contributor version. For |
|
490 purposes of this definition, "control" includes the right to grant |
|
491 patent sublicenses in a manner consistent with the requirements of |
206 this License. |
492 this License. |
207 |
493 |
208 7. If, as a consequence of a court judgment or allegation of patent |
494 Each contributor grants you a non-exclusive, worldwide, royalty-free |
209 infringement or for any other reason (not limited to patent issues), |
495 patent license under the contributor's essential patent claims, to |
210 conditions are imposed on you (whether by court order, agreement or |
496 make, use, sell, offer for sale, import and otherwise run, modify and |
|
497 propagate the contents of its contributor version. |
|
498 |
|
499 In the following three paragraphs, a "patent license" is any express |
|
500 agreement or commitment, however denominated, not to enforce a patent |
|
501 (such as an express permission to practice a patent or covenant not to |
|
502 sue for patent infringement). To "grant" such a patent license to a |
|
503 party means to make such an agreement or commitment not to enforce a |
|
504 patent against the party. |
|
505 |
|
506 If you convey a covered work, knowingly relying on a patent license, |
|
507 and the Corresponding Source of the work is not available for anyone |
|
508 to copy, free of charge and under the terms of this License, through a |
|
509 publicly available network server or other readily accessible means, |
|
510 then you must either (1) cause the Corresponding Source to be so |
|
511 available, or (2) arrange to deprive yourself of the benefit of the |
|
512 patent license for this particular work, or (3) arrange, in a manner |
|
513 consistent with the requirements of this License, to extend the patent |
|
514 license to downstream recipients. "Knowingly relying" means you have |
|
515 actual knowledge that, but for the patent license, your conveying the |
|
516 covered work in a country, or your recipient's use of the covered work |
|
517 in a country, would infringe one or more identifiable patents in that |
|
518 country that you have reason to believe are valid. |
|
519 |
|
520 If, pursuant to or in connection with a single transaction or |
|
521 arrangement, you convey, or propagate by procuring conveyance of, a |
|
522 covered work, and grant a patent license to some of the parties |
|
523 receiving the covered work authorizing them to use, propagate, modify |
|
524 or convey a specific copy of the covered work, then the patent license |
|
525 you grant is automatically extended to all recipients of the covered |
|
526 work and works based on it. |
|
527 |
|
528 A patent license is "discriminatory" if it does not include within |
|
529 the scope of its coverage, prohibits the exercise of, or is |
|
530 conditioned on the non-exercise of one or more of the rights that are |
|
531 specifically granted under this License. You may not convey a covered |
|
532 work if you are a party to an arrangement with a third party that is |
|
533 in the business of distributing software, under which you make payment |
|
534 to the third party based on the extent of your activity of conveying |
|
535 the work, and under which the third party grants, to any of the |
|
536 parties who would receive the covered work from you, a discriminatory |
|
537 patent license (a) in connection with copies of the covered work |
|
538 conveyed by you (or copies made from those copies), or (b) primarily |
|
539 for and in connection with specific products or compilations that |
|
540 contain the covered work, unless you entered into that arrangement, |
|
541 or that patent license was granted, prior to 28 March 2007. |
|
542 |
|
543 Nothing in this License shall be construed as excluding or limiting |
|
544 any implied license or other defenses to infringement that may |
|
545 otherwise be available to you under applicable patent law. |
|
546 |
|
547 12. No Surrender of Others' Freedom. |
|
548 |
|
549 If conditions are imposed on you (whether by court order, agreement or |
211 otherwise) that contradict the conditions of this License, they do not |
550 otherwise) that contradict the conditions of this License, they do not |
212 excuse you from the conditions of this License. If you cannot |
551 excuse you from the conditions of this License. If you cannot convey a |
213 distribute so as to satisfy simultaneously your obligations under this |
552 covered work so as to satisfy simultaneously your obligations under this |
214 License and any other pertinent obligations, then as a consequence you |
553 License and any other pertinent obligations, then as a consequence you may |
215 may not distribute the Program at all. For example, if a patent |
554 not convey it at all. For example, if you agree to terms that obligate you |
216 license would not permit royalty-free redistribution of the Program by |
555 to collect a royalty for further conveying from those to whom you convey |
217 all those who receive copies directly or indirectly through you, then |
556 the Program, the only way you could satisfy both those terms and this |
218 the only way you could satisfy both it and this License would be to |
557 License would be to refrain entirely from conveying the Program. |
219 refrain entirely from distribution of the Program. |
558 |
220 |
559 13. Use with the GNU Affero General Public License. |
221 If any portion of this section is held invalid or unenforceable under |
560 |
222 any particular circumstance, the balance of the section is intended to |
561 Notwithstanding any other provision of this License, you have |
223 apply and the section as a whole is intended to apply in other |
562 permission to link or combine any covered work with a work licensed |
224 circumstances. |
563 under version 3 of the GNU Affero General Public License into a single |
225 |
564 combined work, and to convey the resulting work. The terms of this |
226 It is not the purpose of this section to induce you to infringe any |
565 License will continue to apply to the part which is the covered work, |
227 patents or other property right claims or to contest validity of any |
566 but the special requirements of the GNU Affero General Public License, |
228 such claims; this section has the sole purpose of protecting the |
567 section 13, concerning interaction through a network will apply to the |
229 integrity of the free software distribution system, which is |
568 combination as such. |

569 |
231 generous contributions to the wide range of software distributed |
570 14. Revised Versions of this License. |
232 through that system in reliance on consistent application of that |
571 |
233 system; it is up to the author/donor to decide if he or she is willing |
572 The Free Software Foundation may publish revised and/or new versions of |
234 to distribute software through any other system and a licensee cannot |
573 the GNU General Public License from time to time. Such new versions will |
235 impose that choice. |
|
236 |
|
237 This section is intended to make thoroughly clear what is believed to |
|
238 be a consequence of the rest of this License. |
|
239 |
|
240 8. If the distribution and/or use of the Program is restricted in |
|
241 certain countries either by patents or by copyrighted interfaces, the |
|
242 original copyright holder who places the Program under this License |
|
243 may add an explicit geographical distribution limitation excluding |
|
244 those countries, so that distribution is permitted only in or among |
|
245 countries not thus excluded. In such case, this License incorporates |
|
246 the limitation as if written in the body of this License. |
|
247 |
|
248 9. The Free Software Foundation may publish revised and/or new versions |
|
249 of the General Public License from time to time. Such new versions will |
|
250 be similar in spirit to the present version, but may differ in detail to |
574 be similar in spirit to the present version, but may differ in detail to |
251 address new problems or concerns. |
575 address new problems or concerns. |

253 Each version is given a distinguishing version number. If the Program |
577 Each version is given a distinguishing version number. If the |
254 specifies a version number of this License which applies to it and "any |
578 Program specifies that a certain numbered version of the GNU General |
255 later version", you have the option of following the terms and conditions |
579 Public License "or any later version" applies to it, you have the |
256 either of that version or of any later version published by the Free |
580 option of following the terms and conditions either of that numbered |
257 Software Foundation. If the Program does not specify a version number of |
581 version or of any later version published by the Free Software |
258 this License, you may choose any version ever published by the Free Software |
582 Foundation. If the Program does not specify a version number of the |
259 Foundation. |
583 GNU General Public License, you may choose any version ever published |
260 |
584 by the Free Software Foundation. |
261 10. If you wish to incorporate parts of the Program into other free |
585 |
262 programs whose distribution conditions are different, write to the author |
586 If the Program specifies that a proxy can decide which future |
263 to ask for permission. For software which is copyrighted by the Free |
587 versions of the GNU General Public License can be used, that proxy's |
264 Software Foundation, write to the Free Software Foundation; we sometimes |
588 public statement of acceptance of a version permanently authorizes you |
265 make exceptions for this. Our decision will be guided by the two goals |
589 to choose that version for the Program. |
266 of preserving the free status of all derivatives of our free software and |
590 |
267 of promoting the sharing and reuse of software generally. |
591 Later license versions may give you additional or different |
268 |
592 permissions. However, no additional obligations are imposed on any |
269 NO WARRANTY |
593 author or copyright holder as a result of your choosing to follow a |
270 |
594 later version. |
271 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
595 |
272 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |

|
691 Everyone is permitted to copy and distribute verbatim copies |
|
692 of this license document, but changing it is not allowed. |

|
694 0. PREAMBLE |
|
695 |
|
696 The purpose of this License is to make a manual, textbook, or other |
|
697 functional and useful document "free" in the sense of freedom: to |
|
698 assure everyone the effective freedom to copy and redistribute it, |
|
699 with or without modifying it, either commercially or noncommercially. |
|
700 Secondarily, this License preserves for the author and publisher a way |
|
701 to get credit for their work, while not being considered responsible |
|
702 for modifications made by others. |
|
703 |
|
704 This License is a kind of "copyleft", which means that derivative |
|
705 works of the document must themselves be free in the same sense. It |
|
706 complements the GNU General Public License, which is a copyleft |
|
707 license designed for free software. |
|
708 |
|
709 We have designed this License in order to use it for manuals for free |
|
710 software, because free software needs free documentation: a free |
|
711 program should come with manuals providing the same freedoms that the |
|
712 software does. But this License is not limited to software manuals; |
|
713 it can be used for any textual work, regardless of subject matter or |
|
714 whether it is published as a printed book. We recommend this License |
|
715 principally for works whose purpose is instruction or reference. |
|
716 |
|
717 |
|
718 1. APPLICABILITY AND DEFINITIONS |
|
719 |
|
720 This License applies to any manual or other work, in any medium, that |
|
721 contains a notice placed by the copyright holder saying it can be |
|
722 distributed under the terms of this License. Such a notice grants a |
|
723 world-wide, royalty-free license, unlimited in duration, to use that |
|
724 work under the conditions stated herein. The "Document", below, |
|
725 refers to any such manual or work. Any member of the public is a |
|
726 licensee, and is addressed as "you". You accept the license if you |
|
727 copy, modify or distribute the work in a way requiring permission |
|
728 under copyright law. |
|
729 |
|
730 A "Modified Version" of the Document means any work containing the |
|
731 Document or a portion of it, either copied verbatim, or with |
|
732 modifications and/or translated into another language. |
|
733 |
|
734 A "Secondary Section" is a named appendix or a front-matter section of |
|
735 the Document that deals exclusively with the relationship of the |
|
736 publishers or authors of the Document to the Document's overall |
|
737 subject (or to related matters) and contains nothing that could fall |
|
738 directly within that overall subject. (Thus, if the Document is in |
|
739 part a textbook of mathematics, a Secondary Section may not explain |
|
740 any mathematics.) The relationship could be a matter of historical |
|
741 connection with the subject or with related matters, or of legal, |
|
742 commercial, philosophical, ethical or political position regarding |
|
743 them. |
|
744 |
|
745 The "Invariant Sections" are certain Secondary Sections whose titles |
|
746 are designated, as being those of Invariant Sections, in the notice |
|
747 that says that the Document is released under this License. If a |
|
748 section does not fit the above definition of Secondary then it is not |
|
749 allowed to be designated as Invariant. The Document may contain zero |
|
750 Invariant Sections. If the Document does not identify any Invariant |
|
751 Sections then there are none. |
|
752 |
|
753 The "Cover Texts" are certain short passages of text that are listed, |
|
754 as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
|
755 the Document is released under this License. A Front-Cover Text may |
|
756 be at most 5 words, and a Back-Cover Text may be at most 25 words. |
|
757 |
|
758 A "Transparent" copy of the Document means a machine-readable copy, |
|
759 represented in a format whose specification is available to the |
|
760 general public, that is suitable for revising the document |
|
761 straightforwardly with generic text editors or (for images composed of |
|
762 pixels) generic paint programs or (for drawings) some widely available |
|
763 drawing editor, and that is suitable for input to text formatters or |
|
764 for automatic translation to a variety of formats suitable for input |
|
765 to text formatters. A copy made in an otherwise Transparent file |
|
766 format whose markup, or absence of markup, has been arranged to thwart |
|
767 or discourage subsequent modification by readers is not Transparent. |
|
768 An image format is not Transparent if used for any substantial amount |
|
769 of text. A copy that is not "Transparent" is called "Opaque". |
|
770 |
|
771 Examples of suitable formats for Transparent copies include plain |
|
772 ASCII without markup, Texinfo input format, LaTeX input format, SGML |
|
773 or XML using a publicly available DTD, and standard-conforming simple |
|
774 HTML, PostScript or PDF designed for human modification. Examples of |
|
775 transparent image formats include PNG, XCF and JPG. Opaque formats |
|
776 include proprietary formats that can be read and edited only by |
|
777 proprietary word processors, SGML or XML for which the DTD and/or |
|
778 processing tools are not generally available, and the |
|
779 machine-generated HTML, PostScript or PDF produced by some word |
|
780 processors for output purposes only. |
|
781 |
|
782 The "Title Page" means, for a printed book, the title page itself, |
|
783 plus such following pages as are needed to hold, legibly, the material |
|
784 this License requires to appear in the title page. For works in |
|
785 formats which do not have any title page as such, "Title Page" means |
|
786 the text near the most prominent appearance of the work's title, |
|
787 preceding the beginning of the body of the text. |
|
788 |
|
789 The "publisher" means any person or entity that distributes copies of |
|
790 the Document to the public. |
|
791 |
|
792 A section "Entitled XYZ" means a named subunit of the Document whose |
|
793 title either is precisely XYZ or contains XYZ in parentheses following |
|
794 text that translates XYZ in another language. (Here XYZ stands for a |
|
795 specific section name mentioned below, such as "Acknowledgements", |
|
796 "Dedications", "Endorsements", or "History".) To "Preserve the Title" |
|
797 of such a section when you modify the Document means that it remains a |
|
798 section "Entitled XYZ" according to this definition. |
|
799 |
|
800 The Document may include Warranty Disclaimers next to the notice which |
|
801 states that this License applies to the Document. These Warranty |
|
802 Disclaimers are considered to be included by reference in this |
|
803 License, but only as regards disclaiming warranties: any other |
|
804 implication that these Warranty Disclaimers may have is void and has |
|
805 no effect on the meaning of this License. |
|
806 |
|
807 2. VERBATIM COPYING |
|
808 |
|
809 You may copy and distribute the Document in any medium, either |
|
810 commercially or noncommercially, provided that this License, the |
|
811 copyright notices, and the license notice saying this License applies |
|
812 to the Document are reproduced in all copies, and that you add no |
|
813 other conditions whatsoever to those of this License. You may not use |
|
814 technical measures to obstruct or control the reading or further |
|
815 copying of the copies you make or distribute. However, you may accept |
|
816 compensation in exchange for copies. If you distribute a large enough |
|
817 number of copies you must also follow the conditions in section 3. |
|
818 |
|
819 You may also lend copies, under the same conditions stated above, and |
|
820 you may publicly display copies. |
|
821 |
|
822 |
|
823 3. COPYING IN QUANTITY |
|
824 |
|
825 If you publish printed copies (or copies in media that commonly have |
|
826 printed covers) of the Document, numbering more than 100, and the |
|
827 Document's license notice requires Cover Texts, you must enclose the |
|
828 copies in covers that carry, clearly and legibly, all these Cover |
|
829 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
|
830 the back cover. Both covers must also clearly and legibly identify |
|
831 you as the publisher of these copies. The front cover must present |
|
832 the full title with all words of the title equally prominent and |
|
833 visible. You may add other material on the covers in addition. |
|
834 Copying with changes limited to the covers, as long as they preserve |
|
835 the title of the Document and satisfy these conditions, can be treated |
|
836 as verbatim copying in other respects. |
|
837 |
|
838 If the required texts for either cover are too voluminous to fit |
|
839 legibly, you should put the first ones listed (as many as fit |
|
840 reasonably) on the actual cover, and continue the rest onto adjacent |
|
841 pages. |
|
842 |
|
843 If you publish or distribute Opaque copies of the Document numbering |
|
844 more than 100, you must either include a machine-readable Transparent |
|
845 copy along with each Opaque copy, or state in or with each Opaque copy |
|
846 a computer-network location from which the general network-using |
|
847 public has access to download using public-standard network protocols |
|
848 a complete Transparent copy of the Document, free of added material. |
|
849 If you use the latter option, you must take reasonably prudent steps, |
|
850 when you begin distribution of Opaque copies in quantity, to ensure |
|
851 that this Transparent copy will remain thus accessible at the stated |
|
852 location until at least one year after the last time you distribute an |
|
853 Opaque copy (directly or through your agents or retailers) of that |
|
854 edition to the public. |
|
855 |
|
856 It is requested, but not required, that you contact the authors of the |
|
857 Document well before redistributing any large number of copies, to |
|
858 give them a chance to provide you with an updated version of the |
|
859 Document. |
|
860 |
|
861 |
|
862 4. MODIFICATIONS |
|
863 |
|
864 You may copy and distribute a Modified Version of the Document under |
|
865 the conditions of sections 2 and 3 above, provided that you release |
|
866 the Modified Version under precisely this License, with the Modified |
|
867 Version filling the role of the Document, thus licensing distribution |
|
868 and modification of the Modified Version to whoever possesses a copy |
|
869 of it. In addition, you must do these things in the Modified Version: |
|
870 |
|
871 A. Use in the Title Page (and on the covers, if any) a title distinct |
|
872 from that of the Document, and from those of previous versions |
|
873 (which should, if there were any, be listed in the History section |
|
874 of the Document). You may use the same title as a previous version |
|
875 if the original publisher of that version gives permission. |
|
876 B. List on the Title Page, as authors, one or more persons or entities |
|
877 responsible for authorship of the modifications in the Modified |
|
878 Version, together with at least five of the principal authors of the |
|
879 Document (all of its principal authors, if it has fewer than five), |
|
880 unless they release you from this requirement. |
|
881 C. State on the Title page the name of the publisher of the |
|
882 Modified Version, as the publisher. |
|
883 D. Preserve all the copyright notices of the Document. |
|
884 E. Add an appropriate copyright notice for your modifications |
|
885 adjacent to the other copyright notices. |
|
886 F. Include, immediately after the copyright notices, a license notice |
|
887 giving the public permission to use the Modified Version under the |
|
888 terms of this License, in the form shown in the Addendum below. |
|
889 G. Preserve in that license notice the full lists of Invariant Sections |
|
890 and required Cover Texts given in the Document's license notice. |
|
891 H. Include an unaltered copy of this License. |
|
892 I. Preserve the section Entitled "History", Preserve its Title, and add |
|
893 to it an item stating at least the title, year, new authors, and |
|
894 publisher of the Modified Version as given on the Title Page. If |
|
895 there is no section Entitled "History" in the Document, create one |
|
896 stating the title, year, authors, and publisher of the Document as |
|
897 given on its Title Page, then add an item describing the Modified |
|
898 Version as stated in the previous sentence. |
|
899 J. Preserve the network location, if any, given in the Document for |
|
900 public access to a Transparent copy of the Document, and likewise |
|
901 the network locations given in the Document for previous versions |
|
902 it was based on. These may be placed in the "History" section. |
|
903 You may omit a network location for a work that was published at |
|
904 least four years before the Document itself, or if the original |
|
905 publisher of the version it refers to gives permission. |
|
906 K. For any section Entitled "Acknowledgements" or "Dedications", |
|
907 Preserve the Title of the section, and preserve in the section all |
|
908 the substance and tone of each of the contributor acknowledgements |
|
909 and/or dedications given therein. |
|
910 L. Preserve all the Invariant Sections of the Document, |
|
911 unaltered in their text and in their titles. Section numbers |
|
912 or the equivalent are not considered part of the section titles. |
|
913 M. Delete any section Entitled "Endorsements". Such a section |
|
914 may not be included in the Modified Version. |
|
915 N. Do not retitle any existing section to be Entitled "Endorsements" |
|
916 or to conflict in title with any Invariant Section. |
|
917 O. Preserve any Warranty Disclaimers. |
|
918 |
|
919 If the Modified Version includes new front-matter sections or |
|
920 appendices that qualify as Secondary Sections and contain no material |
|
921 copied from the Document, you may at your option designate some or all |
|
922 of these sections as invariant. To do this, add their titles to the |
|
923 list of Invariant Sections in the Modified Version's license notice. |
|
924 These titles must be distinct from any other section titles. |
|
925 |
|
926 You may add a section Entitled "Endorsements", provided it contains |
|
927 nothing but endorsements of your Modified Version by various |
|
928 parties--for example, statements of peer review or that the text has |
|
929 been approved by an organization as the authoritative definition of a |
|
930 standard. |
|
931 |
|
932 You may add a passage of up to five words as a Front-Cover Text, and a |
|
933 passage of up to 25 words as a Back-Cover Text, to the end of the list |
|
934 of Cover Texts in the Modified Version. Only one passage of |
|
935 Front-Cover Text and one of Back-Cover Text may be added by (or |
|
936 through arrangements made by) any one entity. If the Document already |
|
937 includes a cover text for the same cover, previously added by you or |
|
938 by arrangement made by the same entity you are acting on behalf of, |
|
939 you may not add another; but you may replace the old one, on explicit |
|
940 permission from the previous publisher that added the old one. |
|
941 |
|
942 The author(s) and publisher(s) of the Document do not by this License |
|
943 give permission to use their names for publicity for or to assert or |
|
944 imply endorsement of any Modified Version. |
|
945 |
|
946 |
|
947 5. COMBINING DOCUMENTS |
|
948 |
|
949 You may combine the Document with other documents released under this |
|
950 License, under the terms defined in section 4 above for modified |
|
951 versions, provided that you include in the combination all of the |
|
952 Invariant Sections of all of the original documents, unmodified, and |
|
953 list them all as Invariant Sections of your combined work in its |
|
954 license notice, and that you preserve all their Warranty Disclaimers. |
|
955 |
|
956 The combined work need only contain one copy of this License, and |
|
957 multiple identical Invariant Sections may be replaced with a single |
|
958 copy. If there are multiple Invariant Sections with the same name but |
|
959 different contents, make the title of each such section unique by |
|
960 adding at the end of it, in parentheses, the name of the original |
|
961 author or publisher of that section if known, or else a unique number. |
|
962 Make the same adjustment to the section titles in the list of |
|
963 Invariant Sections in the license notice of the combined work. |
|
964 |
|
965 In the combination, you must combine any sections Entitled "History" |
|
966 in the various original documents, forming one section Entitled |
|
967 "History"; likewise combine any sections Entitled "Acknowledgements", |
|
968 and any sections Entitled "Dedications". You must delete all sections |
|
969 Entitled "Endorsements". |
|
970 |
|
971 |
|
972 6. COLLECTIONS OF DOCUMENTS |
|
973 |
|
974 You may make a collection consisting of the Document and other |
|
975 documents released under this License, and replace the individual |
|
976 copies of this License in the various documents with a single copy |
|
977 that is included in the collection, provided that you follow the rules |
|
978 of this License for verbatim copying of each of the documents in all |
|
979 other respects. |
|
980 |
|
981 You may extract a single document from such a collection, and |
|
982 distribute it individually under this License, provided you insert a |
|
983 copy of this License into the extracted document, and follow this |
|
984 License in all other respects regarding verbatim copying of that |
|
985 document. |
|
986 |
|
987 |
|
988 7. AGGREGATION WITH INDEPENDENT WORKS |
|
989 |
|
990 A compilation of the Document or its derivatives with other separate |
|
991 and independent documents or works, in or on a volume of a storage or |
|
992 distribution medium, is called an "aggregate" if the copyright |
|
993 resulting from the compilation is not used to limit the legal rights |
|
994 of the compilation's users beyond what the individual works permit. |
|
995 When the Document is included in an aggregate, this License does not |
|
996 apply to the other works in the aggregate which are not themselves |
|
997 derivative works of the Document. |
|
998 |
|
999 If the Cover Text requirement of section 3 is applicable to these |
|
1000 copies of the Document, then if the Document is less than one half of |
|
1001 the entire aggregate, the Document's Cover Texts may be placed on |
|
1002 covers that bracket the Document within the aggregate, or the |
|
1003 electronic equivalent of covers if the Document is in electronic form. |
|
1004 Otherwise they must appear on printed covers that bracket the whole |
|
1005 aggregate. |
|
1006 |
|
1007 |
|
1008 8. TRANSLATION |
|
1009 |
|
1010 Translation is considered a kind of modification, so you may |
|
1011 distribute translations of the Document under the terms of section 4. |
|
1012 Replacing Invariant Sections with translations requires special |
|
1013 permission from their copyright holders, but you may include |
|
1014 translations of some or all Invariant Sections in addition to the |
|
1015 original versions of these Invariant Sections. You may include a |
|
1016 translation of this License, and all the license notices in the |
|
1017 Document, and any Warranty Disclaimers, provided that you also include |
|
1018 the original English version of this License and the original versions |
|
1019 of those notices and disclaimers. In case of a disagreement between |
|
1020 the translation and the original version of this License or a notice |
|
1021 or disclaimer, the original version will prevail. |
|
1022 |
|
1023 If a section in the Document is Entitled "Acknowledgements", |
|
1024 "Dedications", or "History", the requirement (section 4) to Preserve |
|
1025 its Title (section 1) will typically require changing the actual |
|
1026 title. |
|
1027 |
|
1028 |
|
1029 9. TERMINATION |
|
1030 |
|
1031 You may not copy, modify, sublicense, or distribute the Document |
|
1032 except as expressly provided under this License. Any attempt |
|
1033 otherwise to copy, modify, sublicense, or distribute it is void, and |
|
1034 will automatically terminate your rights under this License. |
|
1035 |
|
1036 However, if you cease all violation of this License, then your license |
|
1037 from a particular copyright holder is reinstated (a) provisionally, |
|
1038 unless and until the copyright holder explicitly and finally |
|
1039 terminates your license, and (b) permanently, if the copyright holder |
|
1040 fails to notify you of the violation by some reasonable means prior to |
|
1041 60 days after the cessation. |
|
1042 |
|
1043 Moreover, your license from a particular copyright holder is |
|
1044 reinstated permanently if the copyright holder notifies you of the |
|
1045 violation by some reasonable means, this is the first time you have |
|
1046 received notice of violation of this License (for any work) from that |
|
1047 copyright holder, and you cure the violation prior to 30 days after |
|
1048 your receipt of the notice. |
|
1049 |
|
1050 Termination of your rights under this section does not terminate the |
|
1051 licenses of parties who have received copies or rights from you under |
|
1052 this License. If your rights have been terminated and not permanently |
|
1053 reinstated, receipt of a copy of some or all of the same material does |
|
1054 not give you any rights to use it. |
|
1055 |

|
1057 10. FUTURE REVISIONS OF THIS LICENSE |
|
1058 |
|
1059 The Free Software Foundation may publish new, revised versions of the |
|
1060 GNU Free Documentation License from time to time. Such new versions |
|
1061 will be similar in spirit to the present version, but may differ in |
|
1062 detail to address new problems or concerns. See |
|
1063 http://www.gnu.org/copyleft/. |
|
1064 |
|
1065 Each version of the License is given a distinguishing version number. |
|
1066 If the Document specifies that a particular numbered version of this |
|
1067 License "or any later version" applies to it, you have the option of |
|
1068 following the terms and conditions either of that specified version or |
|
1069 of any later version that has been published (not as a draft) by the |
|
1070 Free Software Foundation. If the Document does not specify a version |
|
1071 number of this License, you may choose any version ever published (not |
|
1072 as a draft) by the Free Software Foundation. If the Document |
|
1073 specifies that a proxy can decide which future versions of this |
|
1074 License can be used, that proxy's public statement of acceptance of a |
|
1075 version permanently authorizes you to choose that version for the |
|
1076 Document. |
|
1077 |
|
1078 11. RELICENSING |
|
1079 |
|
1080 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any |
|
1081 World Wide Web server that publishes copyrightable works and also |
|
1082 provides prominent facilities for anybody to edit those works. A |
|
1083 public wiki that anybody can edit is an example of such a server. A |
|
1084 "Massive Multiauthor Collaboration" (or "MMC") contained in the site |
|
1085 means any set of copyrightable works thus published on the MMC site. |
|
1086 |
|
1087 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 |
|
1088 license published by Creative Commons Corporation, a not-for-profit |
|
1089 corporation with a principal place of business in San Francisco, |
|
1090 California, as well as future copyleft versions of that license |
|
1091 published by that same organization. |
|
1092 |
|
1093 "Incorporate" means to publish or republish a Document, in whole or in |
|
1094 part, as part of another Document. |
|
1095 |
|
1096 An MMC is "eligible for relicensing" if it is licensed under this |
|
1097 License, and if all works that were first published under this License |
|
1098 somewhere other than this MMC, and subsequently incorporated in whole or |
|
1099 in part into the MMC, (1) had no cover texts or invariant sections, and |
|
1100 (2) were thus incorporated prior to November 1, 2008. |
|
1101 |
|
1102 The operator of an MMC Site may republish an MMC contained in the site |
|
1103 under CC-BY-SA on the same site at any time before August 1, 2009, |
|
1104 provided the MMC is eligible for relicensing. |

|
1107 ADDENDUM: How to use this License for your documents |
|
1108 |
|
1109 To use this License in a document you have written, include a copy of |
|
1110 the License in the document and put the following copyright and |
|
1111 license notices just after the title page: |
|
1112 |
|
1113 Copyright (c) YEAR YOUR NAME. |
|
1114 Permission is granted to copy, distribute and/or modify this document |
|
1115 under the terms of the GNU Free Documentation License, Version 1.3 |
|
1116 or any later version published by the Free Software Foundation; |
|
1117 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. |
|
1118 A copy of the license is included in the section entitled "GNU |
|
1119 Free Documentation License". |
|
1120 |
|
1121 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, |
|
1122 replace the "with...Texts." line with this: |
|
1123 |
|
1124 with the Invariant Sections being LIST THEIR TITLES, with the |
|
1125 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
|
1126 |
|
1127 If you have Invariant Sections without Cover Texts, or some other |
|
1128 combination of the three, merge those two alternatives to suit the |
|
1129 situation. |
|
1130 |
|
1131 If your document contains nontrivial examples of program code, we |
|
1132 recommend releasing these examples in parallel under your choice of |
|
1133 free software license, such as the GNU General Public License, |
|
1134 to permit their use in free software. |
