74 | \renewcommand{\abstractname}{Preamble} | |
75 | \begin{abstract} | |
76 | The GNU General Public License is a free, copyleft license for | |
77 | software and other kinds of works. | |
78 | ||
79 | The licenses for most software and other practical works are designed | |
80 | to take away your freedom to share and change the works. By contrast, | |
81 | the GNU General Public License is intended to guarantee your freedom to | |
82 | share and change all versions of a program--to make sure it remains free | |
83 | software for all its users. We, the Free Software Foundation, use the | |
84 | GNU General Public License for most of our software; it applies also to | |
85 | any other work released this way by its authors. You can apply it to | |
86 | your programs, too. | |
87 | ||
88 | When we speak of free software, we are referring to freedom, not | |
89 | price. Our General Public Licenses are designed to make sure that you | |
90 | have the freedom to distribute copies of free software (and charge for | |
91 | them if you wish), that you receive source code or can get it if you | |
92 | want it, that you can change the software or use pieces of it in new | |
93 | free programs, and that you know you can do these things. | |
94 | ||
95 | To protect your rights, we need to prevent others from denying you | |
96 | these rights or asking you to surrender the rights. Therefore, you have | |
97 | certain responsibilities if you distribute copies of the software, or if | |
98 | you modify it: responsibilities to respect the freedom of others. | |
99 | ||
100 | For example, if you distribute copies of such a program, whether | |
101 | gratis or for a fee, you must pass on to the recipients the same | |
102 | freedoms that you received. You must make sure that they, too, receive | |
103 | or can get the source code. And you must show them these terms so they | |
104 | know their rights. | |
105 | ||
106 | Developers that use the GNU GPL protect your rights with two steps: | |
107 | (1) assert copyright on the software, and (2) offer you this License | |
108 | giving you legal permission to copy, distribute and/or modify it. | |
109 | ||
110 | For the developers' and authors' protection, the GPL clearly explains | |
111 | that there is no warranty for this free software. For both users' and | |
112 | authors' sake, the GPL requires that modified versions be marked as | |
113 | changed, so that their problems will not be attributed erroneously to | |
114 | authors of previous versions. | |
115 | ||
116 | Some devices are designed to deny users access to install or run | |
117 | modified versions of the software inside them, although the manufacturer | |
118 | can do so. This is fundamentally incompatible with the aim of | |
119 | protecting users' freedom to change the software. The systematic | |
120 | pattern of such abuse occurs in the area of products for individuals to | |
121 | use, which is precisely where it is most unacceptable. Therefore, we | |
122 | have designed this version of the GPL to prohibit the practice for those | |
123 | products. If such problems arise substantially in other domains, we | |
124 | stand ready to extend this provision to those domains in future versions | |
125 | of the GPL, as needed to protect the freedom of users. | |
126 | ||
127 | Finally, every program is threatened constantly by software patents. | |
128 | States should not allow patents to restrict development and use of | |
129 | software on general-purpose computers, but in those that do, we wish to | |
130 | avoid the special danger that patents applied to a free program could | |
131 | make it effectively proprietary. To prevent this, the GPL assures that | |
132 | patents cannot be used to render the program non-free. | |
133 | ||
134 | The precise terms and conditions for copying, distribution and | |
135 | modification follow. | |

139 | {\Large \sc Terms and Conditions} | |
140 | \end{center} | |

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

705 | How to Apply These Terms to Your New Programs | |
706 | \end{center} | |
707 | ||
708 | If you develop a new program, and you want it to be of the greatest | |
709 | possible use to the public, the best way to achieve this is to make it | |
710 | free software which everyone can redistribute and change under these terms. | |
711 | ||
712 | To do so, attach the following notices to the program. It is safest | |
713 | to attach them to the start of each source file to most effectively | |
714 | state the exclusion of warranty; and each file should have at least | |
715 | the ``copyright'' line and a pointer to where the full notice is found. | |
716 | ||
717 | {\footnotesize | |
718 | \begin{verbatim} | |
719 | <one line to give the program's name and a brief idea of what it does.> | |
720 | ||
721 | Copyright (C) <textyear> <name of author> | |
722 | ||
723 | This program is free software: you can redistribute it and/or modify | |
724 | it under the terms of the GNU General Public License as published by | |
725 | the Free Software Foundation, either version 3 of the License, or | |
726 | (at your option) any later version. | |
727 | ||
728 | This program is distributed in the hope that it will be useful, | |
729 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
730 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
731 | GNU General Public License for more details. | |
732 | ||
733 | You should have received a copy of the GNU General Public License | |
734 | along with this program. If not, see <http://www.gnu.org/licenses/>. | |
735 | \end{verbatim} | |
736 | } | |
737 | ||
738 | Also add information on how to contact you by electronic and paper mail. | |
739 | ||
740 | If the program does terminal interaction, make it output a short | |
741 | notice like this when it starts in an interactive mode: | |
742 | ||
743 | {\footnotesize | |
744 | \begin{verbatim} | |
745 | <program> Copyright (C) <year> <name of author> | |
746 | ||
747 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
748 | This is free software, and you are welcome to redistribute it | |
749 | under certain conditions; type `show c' for details. | |
750 | \end{verbatim} | |
751 | } | |
752 | ||
753 | The hypothetical commands {\tt show w} and {\tt show c} should show | |
754 | the appropriate | |
755 | parts of the General Public License. Of course, your program's commands | |
756 | might be different; for a GUI interface, you would use an ``about box''. | |
757 | ||
758 | You should also get your employer (if you work as a programmer) or | |
759 | school, if any, to sign a ``copyright disclaimer'' for the program, if | |
760 | necessary. For more information on this, and how to apply and follow | |
761 | the GNU GPL, see \texttt{http://www.gnu.org/licenses/}. | |
762 | ||
763 | The GNU General Public License does not permit incorporating your | |
764 | program into proprietary programs. If your program is a subroutine | |
765 | library, you may consider it more useful to permit linking proprietary | |
766 | applications with the library. If this is what you want to do, use | |
767 | the GNU Lesser General Public License instead of this License. But | |
768 | first, please read \texttt{http://www.gnu.org/philosophy/why-not-lgpl.html}. | |
769 | ||
