1 GNU GENERAL PUBLIC LICENSE
2 Version 3, 29 June 2007
4 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5 Everyone is permitted to copy and distribute verbatim copies
6 of this license document, but changing it is not allowed.
8 Preamble
10 The GNU General Public License is a free, copyleft license for
11 software and other kinds of works.
13 The licenses for most software and other practical works are designed
14 to take away your freedom to share and change the works. By contrast,
15 the GNU General Public License is intended to guarantee your freedom to
16 share and change all versions of a program--to make sure it remains free
17 software for all its users. We, the Free Software Foundation, use the
18 GNU General Public License for most of our software; it applies also to
19 any other work released this way by its authors. You can apply it to
20 your programs, too.
22 When we speak of free software, we are referring to freedom, not
23 price. Our General Public Licenses are designed to make sure that you
24 have the freedom to distribute copies of free software (and charge for
25 them if you wish), that you receive source code or can get it if you
26 want it, that you can change the software or use pieces of it in new
27 free programs, and that you know you can do these things.
29 To protect your rights, we need to prevent others from denying you
30 these rights or asking you to surrender the rights. Therefore, you have
31 certain responsibilities if you distribute copies of the software, or if
32 you modify it: responsibilities to respect the freedom of others.
34 For example, if you distribute copies of such a program, whether
35 gratis or for a fee, you must pass on to the recipients the same
36 freedoms that you received. You must make sure that they, too, receive
37 or can get the source code. And you must show them these terms so they
38 know their rights.
40 Developers that use the GNU GPL protect your rights with two steps:
41 (1) assert copyright on the software, and (2) offer you this License
42 giving you legal permission to copy, distribute and/or modify it.
44 For the developers' and authors' protection, the GPL clearly explains
45 that there is no warranty for this free software. For both users' and
46 authors' sake, the GPL requires that modified versions be marked as
47 changed, so that their problems will not be attributed erroneously to
48 authors of previous versions.
50 Some devices are designed to deny users access to install or run
51 modified versions of the software inside them, although the manufacturer
52 can do so. This is fundamentally incompatible with the aim of
53 protecting users' freedom to change the software. The systematic
54 pattern of such abuse occurs in the area of products for individuals to
55 use, which is precisely where it is most unacceptable. Therefore, we
56 have designed this version of the GPL to prohibit the practice for those
57 products. If such problems arise substantially in other domains, we
58 stand ready to extend this provision to those domains in future versions
59 of the GPL, as needed to protect the freedom of users.
61 Finally, every program is threatened constantly by software patents.
62 States should not allow patents to restrict development and use of
63 software on general-purpose computers, but in those that do, we wish to
64 avoid the special danger that patents applied to a free program could
65 make it effectively proprietary. To prevent this, the GPL assures that
66 patents cannot be used to render the program non-free.
68 The precise terms and conditions for copying, distribution and
69 modification follow.
71 TERMS AND CONDITIONS
73 0. Definitions.
75 "This License" refers to version 3 of the GNU General Public License.
77 "Copyright" also means copyright-like laws that apply to other kinds of
78 works, such as semiconductor masks.
80 "The Program" refers to any copyrightable work licensed under this
81 License. Each licensee is addressed as "you". "Licensees" and
82 "recipients" may be individuals or organizations.
84 To "modify" a work means to copy from or adapt all or part of the work
85 in a fashion requiring copyright permission, other than the making of an
86 exact copy. The resulting work is called a "modified version" of the
87 earlier work or a work "based on" the earlier work.
89 A "covered work" means either the unmodified Program or a work based
90 on the Program.
92 To "propagate" a work means to do anything with it that, without
93 permission, would make you directly or secondarily liable for
94 infringement under applicable copyright law, except executing it on a
95 computer or modifying a private copy. Propagation includes copying,
96 distribution (with or without modification), making available to the
97 public, and in some countries other activities as well.
99 To "convey" a work means any kind of propagation that enables other
100 parties to make or receive copies. Mere interaction with a user through
101 a computer network, with no transfer of a copy, is not conveying.
103 An interactive user interface displays "Appropriate Legal Notices"
104 to the extent that it includes a convenient and prominently visible
105 feature that (1) displays an appropriate copyright notice, and (2)
106 tells the user that there is no warranty for the work (except to the
107 extent that warranties are provided), that licensees may convey the
108 work under this License, and how to view a copy of this License. If
109 the interface presents a list of user commands or options, such as a
110 menu, a prominent item in the list meets this criterion.
112 1. Source Code.
114 The "source code" for a work means the preferred form of the work
115 for making modifications to it. "Object code" means any non-source
116 form of a work.
118 A "Standard Interface" means an interface that either is an official
119 standard defined by a recognized standards body, or, in the case of
120 interfaces specified for a particular programming language, one that
121 is widely used among developers working in that language.
123 The "System Libraries" of an executable work include anything, other
124 than the work as a whole, that (a) is included in the normal form of
125 packaging a Major Component, but which is not part of that Major
126 Component, and (b) serves only to enable use of the work with that
127 Major Component, or to implement a Standard Interface for which an
128 implementation is available to the public in source code form. A
129 "Major Component", in this context, means a major essential component
130 (kernel, window system, and so on) of the specific operating system
131 (if any) on which the executable work runs, or a compiler used to
132 produce the work, or an object code interpreter used to run it.
134 The "Corresponding Source" for a work in object code form means all
135 the source code needed to generate, install, and (for an executable
136 work) run the object code and to modify the work, including scripts to
137 control those activities. However, it does not include the work's
138 System Libraries, or general-purpose tools or generally available free
139 programs which are used unmodified in performing those activities but
140 which are not part of the work. For example, Corresponding Source
141 includes interface definition files associated with source files for
142 the work, and the source code for shared libraries and dynamically
143 linked subprograms that the work is specifically designed to require,
144 such as by intimate data communication or control flow between those
145 subprograms and other parts of the work.
147 The Corresponding Source need not include anything that users
148 can regenerate automatically from other parts of the Corresponding
149 Source.
151 The Corresponding Source for a work in source code form is that
152 same work.
154 2. Basic Permissions.
156 All rights granted under this License are granted for the term of
157 copyright on the Program, and are irrevocable provided the stated
158 conditions are met. This License explicitly affirms your unlimited
159 permission to run the unmodified Program. The output from running a
160 covered work is covered by this License only if the output, given its
161 content, constitutes a covered work. This License acknowledges your
162 rights of fair use or other equivalent, as provided by copyright law.
164 You may make, run and propagate covered works that you do not
165 convey, without conditions so long as your license otherwise remains
166 in force. You may convey covered works to others for the sole purpose
167 of having them make modifications exclusively for you, or provide you
168 with facilities for running those works, provided that you comply with
169 the terms of this License in conveying all material for which you do
170 not control copyright. Those thus making or running the covered works
171 for you must do so exclusively on your behalf, under your direction
172 and control, on terms that prohibit them from making any copies of
173 your copyrighted material outside their relationship with you.
175 Conveying under any other circumstances is permitted solely under
176 the conditions stated below. Sublicensing is not allowed; section 10
177 makes it unnecessary.
179 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
181 No covered work shall be deemed part of an effective technological
182 measure under any applicable law fulfilling obligations under article
183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
184 similar laws prohibiting or restricting circumvention of such
185 measures.
187 When you convey a covered work, you waive any legal power to forbid
188 circumvention of technological measures to the extent such circumvention
189 is effected by exercising rights under this License with respect to
190 the covered work, and you disclaim any intention to limit operation or
191 modification of the work as a means of enforcing, against the work's
192 users, your or third parties' legal rights to forbid circumvention of
193 technological measures.
195 4. Conveying Verbatim Copies.
197 You may convey verbatim copies of the Program's source code as you
198 receive it, in any medium, provided that you conspicuously and
199 appropriately publish on each copy an appropriate copyright notice;
200 keep intact all notices stating that this License and any
201 non-permissive terms added in accord with section 7 apply to the code;
202 keep intact all notices of the absence of any warranty; and give all
203 recipients a copy of this License along with the Program.
205 You may charge any price or no price for each copy that you convey,
206 and you may offer support or warranty protection for a fee.
208 5. Conveying Modified Source Versions.
210 You may convey a work based on the Program, or the modifications to
211 produce it from the Program, in the form of source code under the
212 terms of section 4, provided that you also meet all of these conditions:
214 a) The work must carry prominent notices stating that you modified
215 it, and giving a relevant date.
217 b) The work must carry prominent notices stating that it is
218 released under this License and any conditions added under section
219 7. This requirement modifies the requirement in section 4 to
220 "keep intact all notices".
222 c) You must license the entire work, as a whole, under this
223 License to anyone who comes into possession of a copy. This
224 License will therefore apply, along with any applicable section 7
225 additional terms, to the whole of the work, and all its parts,
226 regardless of how they are packaged. This License gives no
227 permission to license the work in any other way, but it does not
228 invalidate such permission if you have separately received it.
230 d) If the work has interactive user interfaces, each must display
231 Appropriate Legal Notices; however, if the Program has interactive
232 interfaces that do not display Appropriate Legal Notices, your
233 work need not make them do so.
235 A compilation of a covered work with other separate and independent
236 works, which are not by their nature extensions of the covered work,
237 and which are not combined with it such as to form a larger program,
238 in or on a volume of a storage or distribution medium, is called an
239 "aggregate" if the compilation and its resulting copyright are not
240 used to limit the access or legal rights of the compilation's users
241 beyond what the individual works permit. Inclusion of a covered work
242 in an aggregate does not cause this License to apply to the other
243 parts of the aggregate.
245 6. Conveying Non-Source Forms.
247 You may convey a covered work in object code form under the terms
248 of sections 4 and 5, provided that you also convey the
249 machine-readable Corresponding Source under the terms of this License,
250 in one of these ways:
252 a) Convey the object code in, or embodied in, a physical product
253 (including a physical distribution medium), accompanied by the
254 Corresponding Source fixed on a durable physical medium
255 customarily used for software interchange.
257 b) Convey the object code in, or embodied in, a physical product
258 (including a physical distribution medium), accompanied by a
259 written offer, valid for at least three years and valid for as
260 long as you offer spare parts or customer support for that product
261 model, to give anyone who possesses the object code either (1) a
262 copy of the Corresponding Source for all the software in the
263 product that is covered by this License, on a durable physical
264 medium customarily used for software interchange, for a price no
265 more than your reasonable cost of physically performing this
266 conveying of source, or (2) access to copy the
267 Corresponding Source from a network server at no charge.
269 c) Convey individual copies of the object code with a copy of the
270 written offer to provide the Corresponding Source. This
271 alternative is allowed only occasionally and noncommercially, and
272 only if you received the object code with such an offer, in accord
273 with subsection 6b.
275 d) Convey the object code by offering access from a designated
276 place (gratis or for a charge), and offer equivalent access to the
277 Corresponding Source in the same way through the same place at no
278 further charge. You need not require recipients to copy the
279 Corresponding Source along with the object code. If the place to
280 copy the object code is a network server, the Corresponding Source
281 may be on a different server (operated by you or a third party)
282 that supports equivalent copying facilities, provided you maintain
283 clear directions next to the object code saying where to find the
284 Corresponding Source. Regardless of what server hosts the
285 Corresponding Source, you remain obligated to ensure that it is
286 available for as long as needed to satisfy these requirements.
288 e) Convey the object code using peer-to-peer transmission, provided
289 you inform other peers where the object code and Corresponding
290 Source of the work are being offered to the general public at no
291 charge under subsection 6d.
293 A separable portion of the object code, whose source code is excluded
294 from the Corresponding Source as a System Library, need not be
295 included in conveying the object code work.
297 A "User Product" is either (1) a "consumer product", which means any
298 tangible personal property which is normally used for personal, family,
299 or household purposes, or (2) anything designed or sold for incorporation
300 into a dwelling. In determining whether a product is a consumer product,
301 doubtful cases shall be resolved in favor of coverage. For a particular
302 product received by a particular user, "normally used" refers to a
303 typical or common use of that class of product, regardless of the status
304 of the particular user or of the way in which the particular user
305 actually uses, or expects or is expected to use, the product. A product
306 is a consumer product regardless of whether the product has substantial
307 commercial, industrial or non-consumer uses, unless such uses represent
308 the only significant mode of use of the product.
310 "Installation Information" for a User Product means any methods,
311 procedures, authorization keys, or other information required to install
312 and execute modified versions of a covered work in that User Product from
313 a modified version of its Corresponding Source. The information must
314 suffice to ensure that the continued functioning of the modified object
315 code is in no case prevented or interfered with solely because
316 modification has been made.
318 If you convey an object code work under this section in, or with, or
319 specifically for use in, a User Product, and the conveying occurs as
320 part of a transaction in which the right of possession and use of the
321 User Product is transferred to the recipient in perpetuity or for a
322 fixed term (regardless of how the transaction is characterized), the
323 Corresponding Source conveyed under this section must be accompanied
324 by the Installation Information. But this requirement does not apply
325 if neither you nor any third party retains the ability to install
326 modified object code on the User Product (for example, the work has
327 been installed in ROM).
329 The requirement to provide Installation Information does not include a
330 requirement to continue to provide support service, warranty, or updates
331 for a work that has been modified or installed by the recipient, or for
332 the User Product in which it has been modified or installed. Access to a
333 network may be denied when the modification itself materially and
334 adversely affects the operation of the network or violates the rules and
335 protocols for communication across the network.
337 Corresponding Source conveyed, and Installation Information provided,
338 in accord with this section must be in a format that is publicly
339 documented (and with an implementation available to the public in
340 source code form), and must require no special password or key for
341 unpacking, reading or copying.
343 7. Additional Terms.
345 "Additional permissions" are terms that supplement the terms of this
346 License by making exceptions from one or more of its conditions.
347 Additional permissions that are applicable to the entire Program shall
348 be treated as though they were included in this License, to the extent
349 that they are valid under applicable law. If additional permissions
350 apply only to part of the Program, that part may be used separately
351 under those permissions, but the entire Program remains governed by
352 this License without regard to the additional permissions.
354 When you convey a copy of a covered work, you may at your option
355 remove any additional permissions from that copy, or from any part of
356 it. (Additional permissions may be written to require their own
357 removal in certain cases when you modify the work.) You may place
358 additional permissions on material, added by you to a covered work,
359 for which you have or can give appropriate copyright permission.
361 Notwithstanding any other provision of this License, for material you
362 add to a covered work, you may (if authorized by the copyright holders of
363 that material) supplement the terms of this License with terms:
365 a) Disclaiming warranty or limiting liability differently from the
366 terms of sections 15 and 16 of this License; or
368 b) Requiring preservation of specified reasonable legal notices or
369 author attributions in that material or in the Appropriate Legal
370 Notices displayed by works containing it; or
372 c) Prohibiting misrepresentation of the origin of that material, or
373 requiring that modified versions of such material be marked in
374 reasonable ways as different from the original version; or
376 d) Limiting the use for publicity purposes of names of licensors or
377 authors of the material; or
379 e) Declining to grant rights under trademark law for use of some
380 trade names, trademarks, or service marks; or
382 f) Requiring indemnification of licensors and authors of that
383 material by anyone who conveys the material (or modified versions of
384 it) with contractual assumptions of liability to the recipient, for
385 any liability that these contractual assumptions directly impose on
386 those licensors and authors.
388 All other non-permissive additional terms are considered "further
389 restrictions" within the meaning of section 10. If the Program as you
390 received it, or any part of it, contains a notice stating that it is
391 governed by this License along with a term that is a further
392 restriction, you may remove that term. If a license document contains
393 a further restriction but permits relicensing or conveying under this
394 License, you may add to a covered work material governed by the terms
395 of that license document, provided that the further restriction does
396 not survive such relicensing or conveying.
398 If you add terms to a covered work in accord with this section, you
399 must place, in the relevant source files, a statement of the
400 additional terms that apply to those files, or a notice indicating
401 where to find the applicable terms.
403 Additional terms, permissive or non-permissive, may be stated in the
404 form of a separately written license, or stated as exceptions;
405 the above requirements apply either way.
407 8. Termination.
409 You may not propagate or modify a covered work except as expressly
410 provided under this License. Any attempt otherwise to propagate or
411 modify it is void, and will automatically terminate your rights under
412 this License (including any patent licenses granted under the third
413 paragraph of section 11).
415 However, if you cease all violation of this License, then your
416 license from a particular copyright holder is reinstated (a)
417 provisionally, unless and until the copyright holder explicitly and
418 finally terminates your license, and (b) permanently, if the copyright
419 holder fails to notify you of the violation by some reasonable means
420 prior to 60 days after the cessation.
422 Moreover, your license from a particular copyright holder is
423 reinstated permanently if the copyright holder notifies you of the
424 violation by some reasonable means, this is the first time you have
425 received notice of violation of this License (for any work) from that
426 copyright holder, and you cure the violation prior to 30 days after
427 your receipt of the notice.
429 Termination of your rights under this section does not terminate the
430 licenses of parties who have received copies or rights from you under
431 this License. If your rights have been terminated and not permanently
432 reinstated, you do not qualify to receive new licenses for the same
433 material under section 10.
435 9. Acceptance Not Required for Having Copies.
437 You are not required to accept this License in order to receive or
438 run a copy of the Program. Ancillary propagation of a covered work
439 occurring solely as a consequence of using peer-to-peer transmission
440 to receive a copy likewise does not require acceptance. However,
441 nothing other than this License grants you permission to propagate or
442 modify any covered work. These actions infringe copyright if you do
443 not accept this License. Therefore, by modifying or propagating a
444 covered work, you indicate your acceptance of this License to do so.
446 10. Automatic Licensing of Downstream Recipients.
448 Each time you convey a covered work, the recipient automatically
449 receives a license from the original licensors, to run, modify and
450 propagate that work, subject to this License. You are not responsible
451 for enforcing compliance by third parties with this License.
453 An "entity transaction" is a transaction transferring control of an
454 organization, or substantially all assets of one, or subdividing an
455 organization, or merging organizations. If propagation of a covered
456 work results from an entity transaction, each party to that
457 transaction who receives a copy of the work also receives whatever
458 licenses to the work the party's predecessor in interest had or could
459 give under the previous paragraph, plus a right to possession of the
460 Corresponding Source of the work from the predecessor in interest, if
461 the predecessor has it or can get it with reasonable efforts.
463 You may not impose any further restrictions on the exercise of the
464 rights granted or affirmed under this License. For example, you may
465 not impose a license fee, royalty, or other charge for exercise of
466 rights granted under this License, and you may not initiate litigation
467 (including a cross-claim or counterclaim in a lawsuit) alleging that
468 any patent claim is infringed by making, using, selling, offering for
469 sale, or importing the Program or any portion of it.
471 11. Patents.
473 A "contributor" is a copyright holder who authorizes use under this
474 License of the Program or a work on which the Program is based. The
475 work thus licensed is called the contributor's "contributor version".
477 A contributor's "essential patent claims" are all patent claims
478 owned or controlled by the contributor, whether already acquired or
479 hereafter acquired, that would be infringed by some manner, permitted
480 by this License, of making, using, or selling its contributor version,
481 but do not include claims that would be infringed only as a
482 consequence of further modification of the contributor version. For
483 purposes of this definition, "control" includes the right to grant
484 patent sublicenses in a manner consistent with the requirements of
485 this License.
487 Each contributor grants you a non-exclusive, worldwide, royalty-free
488 patent license under the contributor's essential patent claims, to
489 make, use, sell, offer for sale, import and otherwise run, modify and
490 propagate the contents of its contributor version.
492 In the following three paragraphs, a "patent license" is any express
493 agreement or commitment, however denominated, not to enforce a patent
494 (such as an express permission to practice a patent or covenant not to
495 sue for patent infringement). To "grant" such a patent license to a
496 party means to make such an agreement or commitment not to enforce a
497 patent against the party.
499 If you convey a covered work, knowingly relying on a patent license,
500 and the Corresponding Source of the work is not available for anyone
501 to copy, free of charge and under the terms of this License, through a
502 publicly available network server or other readily accessible means,
503 then you must either (1) cause the Corresponding Source to be so
504 available, or (2) arrange to deprive yourself of the benefit of the
505 patent license for this particular work, or (3) arrange, in a manner
506 consistent with the requirements of this License, to extend the patent
507 license to downstream recipients. "Knowingly relying" means you have
508 actual knowledge that, but for the patent license, your conveying the
509 covered work in a country, or your recipient's use of the covered work
510 in a country, would infringe one or more identifiable patents in that
511 country that you have reason to believe are valid.
513 If, pursuant to or in connection with a single transaction or
514 arrangement, you convey, or propagate by procuring conveyance of, a
515 covered work, and grant a patent license to some of the parties
516 receiving the covered work authorizing them to use, propagate, modify
517 or convey a specific copy of the covered work, then the patent license
518 you grant is automatically extended to all recipients of the covered
519 work and works based on it.
521 A patent license is "discriminatory" if it does not include within
522 the scope of its coverage, prohibits the exercise of, or is
523 conditioned on the non-exercise of one or more of the rights that are
524 specifically granted under this License. You may not convey a covered
525 work if you are a party to an arrangement with a third party that is
526 in the business of distributing software, under which you make payment
527 to the third party based on the extent of your activity of conveying
528 the work, and under which the third party grants, to any of the
529 parties who would receive the covered work from you, a discriminatory
530 patent license (a) in connection with copies of the covered work
531 conveyed by you (or copies made from those copies), or (b) primarily
532 for and in connection with specific products or compilations that
533 contain the covered work, unless you entered into that arrangement,
534 or that patent license was granted, prior to 28 March 2007.
536 Nothing in this License shall be construed as excluding or limiting
537 any implied license or other defenses to infringement that may
538 otherwise be available to you under applicable patent law.
540 12. No Surrender of Others' Freedom.
542 If conditions are imposed on you (whether by court order, agreement or
543 otherwise) that contradict the conditions of this License, they do not
544 excuse you from the conditions of this License. If you cannot convey a
545 covered work so as to satisfy simultaneously your obligations under this
546 License and any other pertinent obligations, then as a consequence you may
547 not convey it at all. For example, if you agree to terms that obligate you
548 to collect a royalty for further conveying from those to whom you convey
549 the Program, the only way you could satisfy both those terms and this
550 License would be to refrain entirely from conveying the Program.
552 13. Use with the GNU Affero General Public License.
554 Notwithstanding any other provision of this License, you have
555 permission to link or combine any covered work with a work licensed
556 under version 3 of the GNU Affero General Public License into a single
557 combined work, and to convey the resulting work. The terms of this
558 License will continue to apply to the part which is the covered work,
559 but the special requirements of the GNU Affero General Public License,
560 section 13, concerning interaction through a network will apply to the
561 combination as such.
563 14. Revised Versions of this License.
565 The Free Software Foundation may publish revised and/or new versions of
566 the GNU General Public License from time to time. Such new versions will
567 be similar in spirit to the present version, but may differ in detail to
568 address new problems or concerns.
570 Each version is given a distinguishing version number. If the
571 Program specifies that a certain numbered version of the GNU General
572 Public License "or any later version" applies to it, you have the
573 option of following the terms and conditions either of that numbered
574 version or of any later version published by the Free Software
575 Foundation. If the Program does not specify a version number of the
576 GNU General Public License, you may choose any version ever published
577 by the Free Software Foundation.
579 If the Program specifies that a proxy can decide which future
580 versions of the GNU General Public License can be used, that proxy's
581 public statement of acceptance of a version permanently authorizes you
582 to choose that version for the Program.
584 Later license versions may give you additional or different
585 permissions. However, no additional obligations are imposed on any
586 author or copyright holder as a result of your choosing to follow a
587 later version.
589 15. Disclaimer of Warranty.
591 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
592 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
596 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
597 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
600 16. Limitation of Liability.
602 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
610 SUCH DAMAGES.
612 17. Interpretation of Sections 15 and 16.
614 If the disclaimer of warranty and limitation of liability provided
615 above cannot be given local legal effect according to their terms,
616 reviewing courts shall apply local law that most closely approximates
617 an absolute waiver of all civil liability in connection with the
618 Program, unless a warranty or assumption of liability accompanies a
619 copy of the Program in return for a fee.
621 END OF TERMS AND CONDITIONS
623 How to Apply These Terms to Your New Programs
625 If you develop a new program, and you want it to be of the greatest
626 possible use to the public, the best way to achieve this is to make it
627 free software which everyone can redistribute and change under these terms.
629 To do so, attach the following notices to the program. It is safest
630 to attach them to the start of each source file to most effectively
631 state the exclusion of warranty; and each file should have at least
632 the "copyright" line and a pointer to where the full notice is found.
634 <one line to give the program's name and a brief idea of what it does.>
635 Copyright (C) <year> <name of author>
637 This program is free software: you can redistribute it and/or modify
638 it under the terms of the GNU General Public License as published by
639 the Free Software Foundation, either version 3 of the License, or
640 (at your option) any later version.
642 This program is distributed in the hope that it will be useful,
643 but WITHOUT ANY WARRANTY; without even the implied warranty of
644 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
645 GNU General Public License for more details.
647 You should have received a copy of the GNU General Public License
648 along with this program. If not, see <http://www.gnu.org/licenses/>.
650 Also add information on how to contact you by electronic and paper mail.
652 If the program does terminal interaction, make it output a short
653 notice like this when it starts in an interactive mode:
655 <program> Copyright (C) <year> <name of author>
656 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
657 This is free software, and you are welcome to redistribute it
658 under certain conditions; type `show c' for details.
660 The hypothetical commands `show w' and `show c' should show the appropriate
661 parts of the General Public License. Of course, your program's commands
662 might be different; for a GUI interface, you would use an "about box".
664 You should also get your employer (if you work as a programmer) or school,
665 if any, to sign a "copyright disclaimer" for the program, if necessary.
666 For more information on this, and how to apply and follow the GNU GPL, see
667 <http://www.gnu.org/licenses/>.
669 The GNU General Public License does not permit incorporating your program
670 into proprietary programs. If your program is a subroutine library, you
671 may consider it more useful to permit linking proprietary applications with
672 the library. If this is what you want to do, use the GNU Lesser General
673 Public License instead of this License. But first, please read
674 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
675 ===============================================================================
676 GNU Free Documentation License
677 Version 1.1, March 2000
679 Copyright (C) 2000 Free Software Foundation, Inc.
680 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
681 Everyone is permitted to copy and distribute verbatim copies
682 of this license document, but changing it is not allowed.
685 0. PREAMBLE
687 The purpose of this License is to make a manual, textbook, or other
688 written document "free" in the sense of freedom: to assure everyone
689 the effective freedom to copy and redistribute it, with or without
690 modifying it, either commercially or noncommercially. Secondarily,
691 this License preserves for the author and publisher a way to get
692 credit for their work, while not being considered responsible for
693 modifications made by others.
695 This License is a kind of "copyleft", which means that derivative
696 works of the document must themselves be free in the same sense. It
697 complements the GNU General Public License, which is a copyleft
698 license designed for free software.
700 We have designed this License in order to use it for manuals for free
701 software, because free software needs free documentation: a free
702 program should come with manuals providing the same freedoms that the
703 software does. But this License is not limited to software manuals;
704 it can be used for any textual work, regardless of subject matter or
705 whether it is published as a printed book. We recommend this License
706 principally for works whose purpose is instruction or reference.
709 1. APPLICABILITY AND DEFINITIONS
711 This License applies to any manual or other work that contains a
712 notice placed by the copyright holder saying it can be distributed
713 under the terms of this License. The "Document", below, refers to any
714 such manual or work. Any member of the public is a licensee, and is
715 addressed as "you".
717 A "Modified Version" of the Document means any work containing the
718 Document or a portion of it, either copied verbatim, or with
719 modifications and/or translated into another language.
721 A "Secondary Section" is a named appendix or a front-matter section of
722 the Document that deals exclusively with the relationship of the
723 publishers or authors of the Document to the Document's overall subject
724 (or to related matters) and contains nothing that could fall directly
725 within that overall subject. (For example, if the Document is in part a
726 textbook of mathematics, a Secondary Section may not explain any
727 mathematics.) The relationship could be a matter of historical
728 connection with the subject or with related matters, or of legal,
729 commercial, philosophical, ethical or political position regarding
730 them.
732 The "Invariant Sections" are certain Secondary Sections whose titles
733 are designated, as being those of Invariant Sections, in the notice
734 that says that the Document is released under this License.
736 The "Cover Texts" are certain short passages of text that are listed,
737 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
738 the Document is released under this License.
740 A "Transparent" copy of the Document means a machine-readable copy,
741 represented in a format whose specification is available to the
742 general public, whose contents can be viewed and edited directly and
743 straightforwardly with generic text editors or (for images composed of
744 pixels) generic paint programs or (for drawings) some widely available
745 drawing editor, and that is suitable for input to text formatters or
746 for automatic translation to a variety of formats suitable for input
747 to text formatters. A copy made in an otherwise Transparent file
748 format whose markup has been designed to thwart or discourage
749 subsequent modification by readers is not Transparent. A copy that is
750 not "Transparent" is called "Opaque".
752 Examples of suitable formats for Transparent copies include plain
753 ASCII without markup, Texinfo input format, LaTeX input format, SGML
754 or XML using a publicly available DTD, and standard-conforming simple
755 HTML designed for human modification. Opaque formats include
756 PostScript, PDF, proprietary formats that can be read and edited only
757 by proprietary word processors, SGML or XML for which the DTD and/or
758 processing tools are not generally available, and the
759 machine-generated HTML produced by some word processors for output
760 purposes only.
762 The "Title Page" means, for a printed book, the title page itself,
763 plus such following pages as are needed to hold, legibly, the material
764 this License requires to appear in the title page. For works in
765 formats which do not have any title page as such, "Title Page" means
766 the text near the most prominent appearance of the work's title,
767 preceding the beginning of the body of the text.
770 2. VERBATIM COPYING
772 You may copy and distribute the Document in any medium, either
773 commercially or noncommercially, provided that this License, the
774 copyright notices, and the license notice saying this License applies
775 to the Document are reproduced in all copies, and that you add no other
776 conditions whatsoever to those of this License. You may not use
777 technical measures to obstruct or control the reading or further
778 copying of the copies you make or distribute. However, you may accept
779 compensation in exchange for copies. If you distribute a large enough
780 number of copies you must also follow the conditions in section 3.
782 You may also lend copies, under the same conditions stated above, and
783 you may publicly display copies.
786 3. COPYING IN QUANTITY
788 If you publish printed copies of the Document numbering more than 100,
789 and the Document's license notice requires Cover Texts, you must enclose
790 the copies in covers that carry, clearly and legibly, all these Cover
791 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
792 the back cover. Both covers must also clearly and legibly identify
793 you as the publisher of these copies. The front cover must present
794 the full title with all words of the title equally prominent and
795 visible. You may add other material on the covers in addition.
796 Copying with changes limited to the covers, as long as they preserve
797 the title of the Document and satisfy these conditions, can be treated
798 as verbatim copying in other respects.
800 If the required texts for either cover are too voluminous to fit
801 legibly, you should put the first ones listed (as many as fit
802 reasonably) on the actual cover, and continue the rest onto adjacent
803 pages.
805 If you publish or distribute Opaque copies of the Document numbering
806 more than 100, you must either include a machine-readable Transparent
807 copy along with each Opaque copy, or state in or with each Opaque copy
808 a publicly-accessible computer-network location containing a complete
809 Transparent copy of the Document, free of added material, which the
810 general network-using public has access to download anonymously at no
811 charge using public-standard network protocols. If you use the latter
812 option, you must take reasonably prudent steps, when you begin
813 distribution of Opaque copies in quantity, to ensure that this
814 Transparent copy will remain thus accessible at the stated location
815 until at least one year after the last time you distribute an Opaque
816 copy (directly or through your agents or retailers) of that edition to
817 the public.
819 It is requested, but not required, that you contact the authors of the
820 Document well before redistributing any large number of copies, to give
821 them a chance to provide you with an updated version of the Document.
824 4. MODIFICATIONS
826 You may copy and distribute a Modified Version of the Document under
827 the conditions of sections 2 and 3 above, provided that you release
828 the Modified Version under precisely this License, with the Modified
829 Version filling the role of the Document, thus licensing distribution
830 and modification of the Modified Version to whoever possesses a copy
831 of it. In addition, you must do these things in the Modified Version:
833 A. Use in the Title Page (and on the covers, if any) a title distinct
834 from that of the Document, and from those of previous versions
835 (which should, if there were any, be listed in the History section
836 of the Document). You may use the same title as a previous version
837 if the original publisher of that version gives permission.
838 B. List on the Title Page, as authors, one or more persons or entities
839 responsible for authorship of the modifications in the Modified
840 Version, together with at least five of the principal authors of the
841 Document (all of its principal authors, if it has less than five).
842 C. State on the Title page the name of the publisher of the
843 Modified Version, as the publisher.
844 D. Preserve all the copyright notices of the Document.
845 E. Add an appropriate copyright notice for your modifications
846 adjacent to the other copyright notices.
847 F. Include, immediately after the copyright notices, a license notice
848 giving the public permission to use the Modified Version under the
849 terms of this License, in the form shown in the Addendum below.
850 G. Preserve in that license notice the full lists of Invariant Sections
851 and required Cover Texts given in the Document's license notice.
852 H. Include an unaltered copy of this License.
853 I. Preserve the section entitled "History", and its title, and add to
854 it an item stating at least the title, year, new authors, and
855 publisher of the Modified Version as given on the Title Page. If
856 there is no section entitled "History" in the Document, create one
857 stating the title, year, authors, and publisher of the Document as
858 given on its Title Page, then add an item describing the Modified
859 Version as stated in the previous sentence.
860 J. Preserve the network location, if any, given in the Document for
861 public access to a Transparent copy of the Document, and likewise
862 the network locations given in the Document for previous versions
863 it was based on. These may be placed in the "History" section.
864 You may omit a network location for a work that was published at
865 least four years before the Document itself, or if the original
866 publisher of the version it refers to gives permission.
867 K. In any section entitled "Acknowledgements" or "Dedications",
868 preserve the section's title, and preserve in the section all the
869 substance and tone of each of the contributor acknowledgements
870 and/or dedications given therein.
871 L. Preserve all the Invariant Sections of the Document,
872 unaltered in their text and in their titles. Section numbers
873 or the equivalent are not considered part of the section titles.
874 M. Delete any section entitled "Endorsements". Such a section
875 may not be included in the Modified Version.
876 N. Do not retitle any existing section as "Endorsements"
877 or to conflict in title with any Invariant Section.
879 If the Modified Version includes new front-matter sections or
880 appendices that qualify as Secondary Sections and contain no material
881 copied from the Document, you may at your option designate some or all
882 of these sections as invariant. To do this, add their titles to the
883 list of Invariant Sections in the Modified Version's license notice.
884 These titles must be distinct from any other section titles.
886 You may add a section entitled "Endorsements", provided it contains
887 nothing but endorsements of your Modified Version by various
888 parties--for example, statements of peer review or that the text has
889 been approved by an organization as the authoritative definition of a
890 standard.
892 You may add a passage of up to five words as a Front-Cover Text, and a
893 passage of up to 25 words as a Back-Cover Text, to the end of the list
894 of Cover Texts in the Modified Version. Only one passage of
895 Front-Cover Text and one of Back-Cover Text may be added by (or
896 through arrangements made by) any one entity. If the Document already
897 includes a cover text for the same cover, previously added by you or
898 by arrangement made by the same entity you are acting on behalf of,
899 you may not add another; but you may replace the old one, on explicit
900 permission from the previous publisher that added the old one.
902 The author(s) and publisher(s) of the Document do not by this License
903 give permission to use their names for publicity for or to assert or
904 imply endorsement of any Modified Version.
907 5. COMBINING DOCUMENTS
909 You may combine the Document with other documents released under this
910 License, under the terms defined in section 4 above for modified
911 versions, provided that you include in the combination all of the
912 Invariant Sections of all of the original documents, unmodified, and
913 list them all as Invariant Sections of your combined work in its
914 license notice.
916 The combined work need only contain one copy of this License, and
917 multiple identical Invariant Sections may be replaced with a single
918 copy. If there are multiple Invariant Sections with the same name but
919 different contents, make the title of each such section unique by
920 adding at the end of it, in parentheses, the name of the original
921 author or publisher of that section if known, or else a unique number.
922 Make the same adjustment to the section titles in the list of
923 Invariant Sections in the license notice of the combined work.
925 In the combination, you must combine any sections entitled "History"
926 in the various original documents, forming one section entitled
927 "History"; likewise combine any sections entitled "Acknowledgements",
928 and any sections entitled "Dedications". You must delete all sections
929 entitled "Endorsements."
932 6. COLLECTIONS OF DOCUMENTS
934 You may make a collection consisting of the Document and other documents
935 released under this License, and replace the individual copies of this
936 License in the various documents with a single copy that is included in
937 the collection, provided that you follow the rules of this License for
938 verbatim copying of each of the documents in all other respects.
940 You may extract a single document from such a collection, and distribute
941 it individually under this License, provided you insert a copy of this
942 License into the extracted document, and follow this License in all
943 other respects regarding verbatim copying of that document.
946 7. AGGREGATION WITH INDEPENDENT WORKS
948 A compilation of the Document or its derivatives with other separate
949 and independent documents or works, in or on a volume of a storage or
950 distribution medium, does not as a whole count as a Modified Version
951 of the Document, provided no compilation copyright is claimed for the
952 compilation. Such a compilation is called an "aggregate", and this
953 License does not apply to the other self-contained works thus compiled
954 with the Document, on account of their being thus compiled, if they
955 are not themselves derivative works of the Document.
957 If the Cover Text requirement of section 3 is applicable to these
958 copies of the Document, then if the Document is less than one quarter
959 of the entire aggregate, the Document's Cover Texts may be placed on
960 covers that surround only the Document within the aggregate.
961 Otherwise they must appear on covers around the whole aggregate.
964 8. TRANSLATION
966 Translation is considered a kind of modification, so you may
967 distribute translations of the Document under the terms of section 4.
968 Replacing Invariant Sections with translations requires special
969 permission from their copyright holders, but you may include
970 translations of some or all Invariant Sections in addition to the
971 original versions of these Invariant Sections. You may include a
972 translation of this License provided that you also include the
973 original English version of this License. In case of a disagreement
974 between the translation and the original English version of this
975 License, the original English version will prevail.
978 9. TERMINATION
980 You may not copy, modify, sublicense, or distribute the Document except
981 as expressly provided for under this License. Any other attempt to
982 copy, modify, sublicense or distribute the Document is void, and will
983 automatically terminate your rights under this License. However,
984 parties who have received copies, or rights, from you under this
985 License will not have their licenses terminated so long as such
986 parties remain in full compliance.
989 10. FUTURE REVISIONS OF THIS LICENSE
991 The Free Software Foundation may publish new, revised versions
992 of the GNU Free Documentation License from time to time. Such new
993 versions will be similar in spirit to the present version, but may
994 differ in detail to address new problems or concerns. See
995 http://www.gnu.org/copyleft/.
997 Each version of the License is given a distinguishing version number.
998 If the Document specifies that a particular numbered version of this
999 License "or any later version" applies to it, you have the option of
1000 following the terms and conditions either of that specified version or
1001 of any later version that has been published (not as a draft) by the
1002 Free Software Foundation. If the Document does not specify a version
1003 number of this License, you may choose any version ever published (not
1004 as a draft) by the Free Software Foundation.
1007 ADDENDUM: How to use this License for your documents
1009 To use this License in a document you have written, include a copy of
1010 the License in the document and put the following copyright and
1011 license notices just after the title page:
1013 Copyright (c) YEAR YOUR NAME.
1014 Permission is granted to copy, distribute and/or modify this document
1015 under the terms of the GNU Free Documentation License, Version 1.1
1016 or any later version published by the Free Software Foundation;
1017 with the Invariant Sections being LIST THEIR TITLES, with the
1018 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
1019 A copy of the license is included in the section entitled "GNU
1020 Free Documentation License".
1022 If you have no Invariant Sections, write "with no Invariant Sections"
1023 instead of saying which ones are invariant. If you have no
1024 Front-Cover Texts, write "no Front-Cover Texts" instead of
1025 "Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
1027 If your document contains nontrivial examples of program code, we
1028 recommend releasing these examples in parallel under your choice of
1029 free software license, such as the GNU General Public License,
1030 to permit their use in free software.
