9 Everyone is permitted to copy and distribute verbatim copies
10 of this license document, but changing it is not allowed.
14 The licenses for most software are designed to take away your
15 freedom to share and change it. By contrast, the GNU General Public
16 License is intended to guarantee your freedom to share and change free
17 software--to make sure the software is free for all its users. This
18 General Public License applies to most of the Free Software
19 Foundation's software and to any other program whose authors commit to
20 using it. (Some other Free Software Foundation software is covered by
21 the GNU Library General Public License instead.) You can apply it to
24 When we speak of free software, we are referring to freedom, not
25 price. Our General Public Licenses are designed to make sure that you
26 have the freedom to distribute copies of free software (and charge for
27 this service if you wish), that you receive source code or can get it
28 if you want it, that you can change the software or use pieces of it
29 in new free programs; and that you know you can do these things.
31 To protect your rights, we need to make restrictions that forbid
32 anyone to deny you these rights or to ask you to surrender the rights.
33 These restrictions translate to certain responsibilities for you if you
34 distribute copies of the software, or if you modify it.
36 For example, if you distribute copies of such a program, whether
37 gratis or for a fee, you must give the recipients all the rights that
38 you have. You must make sure that they, too, receive or can get the
39 source code. And you must show them these terms so they know their
42 We protect your rights with two steps: (1) copyright the software, and
43 (2) offer you this license which gives you legal permission to copy,
44 distribute and/or modify the software.
46 Also, for each author's protection and ours, we want to make certain
47 that everyone understands that there is no warranty for this free
48 software. If the software is modified by someone else and passed on, we
49 want its recipients to know that what they have is not the original, so
50 that any problems introduced by others will not reflect on the original
53 Finally, any free program is threatened constantly by software
54 patents. We wish to avoid the danger that redistributors of a free
55 program will individually obtain patent licenses, in effect making the
56 program proprietary. To prevent this, we have made it clear that any
57 patent must be licensed for everyone's free use or not licensed at all.
59 The precise terms and conditions for copying, distribution and
62 GNU GENERAL PUBLIC LICENSE
63 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
65 0. This License applies to any program or other work which contains
66 a notice placed by the copyright holder saying it may be distributed
67 under the terms of this General Public License. The "Program", below,
68 refers to any such program or work, and a "work based on the Program"
69 means either the Program or any derivative work under copyright law:
70 that is to say, a work containing the Program or a portion of it,
71 either verbatim or with modifications and/or translated into another
72 language. (Hereinafter, translation is included without limitation in
73 the term "modification".) Each licensee is addressed as "you".
75 Activities other than copying, distribution and modification are not
76 covered by this License; they are outside its scope. The act of
77 running the Program is not restricted, and the output from the Program
78 is covered only if its contents constitute a work based on the
79 Program (independent of having been made by running the Program).
80 Whether that is true depends on what the Program does.
82 1. You may copy and distribute verbatim copies of the Program's
83 source code as you receive it, in any medium, provided that you
84 conspicuously and appropriately publish on each copy an appropriate
85 copyright notice and disclaimer of warranty; keep intact all the
86 notices that refer to this License and to the absence of any warranty;
87 and give any other recipients of the Program a copy of this License
88 along with the Program.
90 You may charge a fee for the physical act of transferring a copy, and
91 you may at your option offer warranty protection in exchange for a fee.
93 2. You may modify your copy or copies of the Program or any portion
94 of it, thus forming a work based on the Program, and copy and
95 distribute such modifications or work under the terms of Section 1
96 above, provided that you also meet all of these conditions:
98 a) You must cause the modified files to carry prominent notices
99 stating that you changed the files and the date of any change.
101 b) You must cause any work that you distribute or publish, that in
102 whole or in part contains or is derived from the Program or any
103 part thereof, to be licensed as a whole at no charge to all third
104 parties under the terms of this License.
106 c) If the modified program normally reads commands interactively
107 when run, you must cause it, when started running for such
108 interactive use in the most ordinary way, to print or display an
109 announcement including an appropriate copyright notice and a
110 notice that there is no warranty (or else, saying that you provide
111 a warranty) and that users may redistribute the program under
112 these conditions, and telling the user how to view a copy of this
113 License. (Exception: if the Program itself is interactive but
114 does not normally print such an announcement, your work based on
115 the Program is not required to print an announcement.)
117 These requirements apply to the modified work as a whole. If
118 identifiable sections of that work are not derived from the Program,
119 and can be reasonably considered independent and separate works in
120 themselves, then this License, and its terms, do not apply to those
121 sections when you distribute them as separate works. But when you
122 distribute the same sections as part of a whole which is a work based
123 on the Program, the distribution of the whole must be on the terms of
124 this License, whose permissions for other licensees extend to the
125 entire whole, and thus to each and every part regardless of who wrote it.
127 Thus, it is not the intent of this section to claim rights or contest
128 your rights to work written entirely by you; rather, the intent is to
129 exercise the right to control the distribution of derivative or
130 collective works based on the Program.
132 In addition, mere aggregation of another work not based on the Program
133 with the Program (or with a work based on the Program) on a volume of
134 a storage or distribution medium does not bring the other work under
135 the scope of this License.
137 3. You may copy and distribute the Program (or a work based on it,
138 under Section 2) in object code or executable form under the terms of
139 Sections 1 and 2 above provided that you also do one of the following:
141 a) Accompany it with the complete corresponding machine-readable
142 source code, which must be distributed under the terms of Sections
143 1 and 2 above on a medium customarily used for software interchange; or,
145 b) Accompany it with a written offer, valid for at least three
146 years, to give any third party, for a charge no more than your
147 cost of physically performing source distribution, a complete
148 machine-readable copy of the corresponding source code, to be
149 distributed under the terms of Sections 1 and 2 above on a medium
150 customarily used for software interchange; or,
152 c) Accompany it with the information you received as to the offer
153 to distribute corresponding source code. (This alternative is
154 allowed only for noncommercial distribution and only if you
155 received the program in object code or executable form with such
156 an offer, in accord with Subsection b above.)
158 The source code for a work means the preferred form of the work for
159 making modifications to it. For an executable work, complete source
160 code means all the source code for all modules it contains, plus any
161 associated interface definition files, plus the scripts used to
162 control compilation and installation of the executable. However, as a
163 special exception, the source code distributed need not include
164 anything that is normally distributed (in either source or binary
165 form) with the major components (compiler, kernel, and so on) of the
166 operating system on which the executable runs, unless that component
167 itself accompanies the executable.
169 If distribution of executable or object code is made by offering
170 access to copy from a designated place, then offering equivalent
171 access to copy the source code from the same place counts as
172 distribution of the source code, even though third parties are not
173 compelled to copy the source along with the object code.
175 4. You may not copy, modify, sublicense, or distribute the Program
176 except as expressly provided under this License. Any attempt
177 otherwise to copy, modify, sublicense or distribute the Program is
178 void, and will automatically terminate your rights under this License.
179 However, parties who have received copies, or rights, from you under
180 this License will not have their licenses terminated so long as such
181 parties remain in full compliance.
183 5. You are not required to accept this License, since you have not
184 signed it. However, nothing else grants you permission to modify or
185 distribute the Program or its derivative works. These actions are
186 prohibited by law if you do not accept this License. Therefore, by
187 modifying or distributing the Program (or any work based on the
188 Program), you indicate your acceptance of this License to do so, and
189 all its terms and conditions for copying, distributing or modifying
190 the Program or works based on it.
192 6. Each time you redistribute the Program (or any work based on the
193 Program), the recipient automatically receives a license from the
194 original licensor to copy, distribute or modify the Program subject to
195 these terms and conditions. You may not impose any further
196 restrictions on the recipients' exercise of the rights granted herein.
197 You are not responsible for enforcing compliance by third parties to
200 7. If, as a consequence of a court judgment or allegation of patent
201 infringement or for any other reason (not limited to patent issues),
202 conditions are imposed on you (whether by court order, agreement or
203 otherwise) that contradict the conditions of this License, they do not
204 excuse you from the conditions of this License. If you cannot
205 distribute so as to satisfy simultaneously your obligations under this
206 License and any other pertinent obligations, then as a consequence you
207 may not distribute the Program at all. For example, if a patent
208 license would not permit royalty-free redistribution of the Program by
209 all those who receive copies directly or indirectly through you, then
210 the only way you could satisfy both it and this License would be to
211 refrain entirely from distribution of the Program.
213 If any portion of this section is held invalid or unenforceable under
214 any particular circumstance, the balance of the section is intended to
215 apply and the section as a whole is intended to apply in other
218 It is not the purpose of this section to induce you to infringe any
219 patents or other property right claims or to contest validity of any
220 such claims; this section has the sole purpose of protecting the
221 integrity of the free software distribution system, which is
222 implemented by public license practices. Many people have made
223 generous contributions to the wide range of software distributed
224 through that system in reliance on consistent application of that
225 system; it is up to the author/donor to decide if he or she is willing
226 to distribute software through any other system and a licensee cannot
229 This section is intended to make thoroughly clear what is believed to
230 be a consequence of the rest of this License.
232 8. If the distribution and/or use of the Program is restricted in
233 certain countries either by patents or by copyrighted interfaces, the
234 original copyright holder who places the Program under this License
235 may add an explicit geographical distribution limitation excluding
236 those countries, so that distribution is permitted only in or among
237 countries not thus excluded. In such case, this License incorporates
238 the limitation as if written in the body of this License.
240 9. The Free Software Foundation may publish revised and/or new versions
241 of the General Public License from time to time. Such new versions will
242 be similar in spirit to the present version, but may differ in detail to
243 address new problems or concerns.
245 Each version is given a distinguishing version number. If the Program
246 specifies a version number of this License which applies to it and "any
247 later version", you have the option of following the terms and conditions
248 either of that version or of any later version published by the Free
249 Software Foundation. If the Program does not specify a version number of
250 this License, you may choose any version ever published by the Free Software
253 10. If you wish to incorporate parts of the Program into other free
254 programs whose distribution conditions are different, write to the author
255 to ask for permission. For software which is copyrighted by the Free
256 Software Foundation, write to the Free Software Foundation; we sometimes
257 make exceptions for this. Our decision will be guided by the two goals
258 of preserving the free status of all derivatives of our free software and
259 of promoting the sharing and reuse of software generally.
263 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
264 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
265 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
266 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
267 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
268 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
269 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
270 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
271 REPAIR OR CORRECTION.
273 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
274 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
275 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
276 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
277 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
278 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
279 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
280 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
281 POSSIBILITY OF SUCH DAMAGES.
283 END OF TERMS AND CONDITIONS
285 How to Apply These Terms to Your New Programs
287 If you develop a new program, and you want it to be of the greatest
288 possible use to the public, the best way to achieve this is to make it
289 free software which everyone can redistribute and change under these terms.
291 To do so, attach the following notices to the program. It is safest
292 to attach them to the start of each source file to most effectively
293 convey the exclusion of warranty; and each file should have at least
294 the "copyright" line and a pointer to where the full notice is found.
296 <one line to give the program's name and a brief idea of what it does.>
297 Copyright (C) <year> <name of author>
299 This program is free software; you can redistribute it and/or modify
300 it under the terms of the GNU General Public License as published by
301 the Free Software Foundation; either version 2 of the License, or
302 (at your option) any later version.
304 This program is distributed in the hope that it will be useful,
305 but WITHOUT ANY WARRANTY; without even the implied warranty of
306 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
307 GNU General Public License for more details.
309 You should have received a copy of the GNU General Public License
310 along with this program; if not, write to the Free Software
311 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
314 Also add information on how to contact you by electronic and paper mail.
316 If the program is interactive, make it output a short notice like this
317 when it starts in an interactive mode:
319 Gnomovision version 69, Copyright (C) year name of author
320 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
321 This is free software, and you are welcome to redistribute it
322 under certain conditions; type `show c' for details.
324 The hypothetical commands `show w' and `show c' should show the appropriate
325 parts of the General Public License. Of course, the commands you use may
326 be called something other than `show w' and `show c'; they could even be
327 mouse-clicks or menu items--whatever suits your program.
329 You should also get your employer (if you work as a programmer) or your
330 school, if any, to sign a "copyright disclaimer" for the program, if
331 necessary. Here is a sample; alter the names:
333 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
334 `Gnomovision' (which makes passes at compilers) written by James Hacker.
336 <signature of Ty Coon>, 1 April 1989
337 Ty Coon, President of Vice
339 This General Public License does not permit incorporating your program into
340 proprietary programs. If your program is a subroutine library, you may
341 consider it more useful to permit linking proprietary applications with the
342 library. If this is what you want to do, use the GNU Library General
343 Public License instead of this License.

352 Everyone is permitted to copy and distribute verbatim copies
353 of this license document, but changing it is not allowed.
358 The purpose of this License is to make a manual, textbook, or other
359 written document "free" in the sense of freedom: to assure everyone
360 the effective freedom to copy and redistribute it, with or without
361 modifying it, either commercially or noncommercially. Secondarily,
362 this License preserves for the author and publisher a way to get
363 credit for their work, while not being considered responsible for
364 modifications made by others.
366 This License is a kind of "copyleft", which means that derivative
367 works of the document must themselves be free in the same sense. It
368 complements the GNU General Public License, which is a copyleft
369 license designed for free software.
371 We have designed this License in order to use it for manuals for free
372 software, because free software needs free documentation: a free
373 program should come with manuals providing the same freedoms that the
374 software does. But this License is not limited to software manuals;
375 it can be used for any textual work, regardless of subject matter or
376 whether it is published as a printed book. We recommend this License
377 principally for works whose purpose is instruction or reference.
380 1. APPLICABILITY AND DEFINITIONS
382 This License applies to any manual or other work that contains a
383 notice placed by the copyright holder saying it can be distributed
384 under the terms of this License. The "Document", below, refers to any
385 such manual or work. Any member of the public is a licensee, and is
388 A "Modified Version" of the Document means any work containing the
389 Document or a portion of it, either copied verbatim, or with
390 modifications and/or translated into another language.
392 A "Secondary Section" is a named appendix or a front-matter section of
393 the Document that deals exclusively with the relationship of the
394 publishers or authors of the Document to the Document's overall subject
395 (or to related matters) and contains nothing that could fall directly
396 within that overall subject. (For example, if the Document is in part a
397 textbook of mathematics, a Secondary Section may not explain any
398 mathematics.) The relationship could be a matter of historical
399 connection with the subject or with related matters, or of legal,
400 commercial, philosophical, ethical or political position regarding
403 The "Invariant Sections" are certain Secondary Sections whose titles
404 are designated, as being those of Invariant Sections, in the notice
405 that says that the Document is released under this License.
407 The "Cover Texts" are certain short passages of text that are listed,
408 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
409 the Document is released under this License.
411 A "Transparent" copy of the Document means a machine-readable copy,
412 represented in a format whose specification is available to the
413 general public, whose contents can be viewed and edited directly and
414 straightforwardly with generic text editors or (for images composed of
415 pixels) generic paint programs or (for drawings) some widely available
416 drawing editor, and that is suitable for input to text formatters or
417 for automatic translation to a variety of formats suitable for input
418 to text formatters. A copy made in an otherwise Transparent file
419 format whose markup has been designed to thwart or discourage
420 subsequent modification by readers is not Transparent. A copy that is
421 not "Transparent" is called "Opaque".
423 Examples of suitable formats for Transparent copies include plain
424 ASCII without markup, Texinfo input format, LaTeX input format, SGML
425 or XML using a publicly available DTD, and standard-conforming simple
426 HTML designed for human modification. Opaque formats include
427 PostScript, PDF, proprietary formats that can be read and edited only
428 by proprietary word processors, SGML or XML for which the DTD and/or
429 processing tools are not generally available, and the
430 machine-generated HTML produced by some word processors for output
433 The "Title Page" means, for a printed book, the title page itself,
434 plus such following pages as are needed to hold, legibly, the material
435 this License requires to appear in the title page. For works in
436 formats which do not have any title page as such, "Title Page" means
437 the text near the most prominent appearance of the work's title,
438 preceding the beginning of the body of the text.
443 You may copy and distribute the Document in any medium, either
444 commercially or noncommercially, provided that this License, the
445 copyright notices, and the license notice saying this License applies
446 to the Document are reproduced in all copies, and that you add no other
447 conditions whatsoever to those of this License. You may not use
448 technical measures to obstruct or control the reading or further
449 copying of the copies you make or distribute. However, you may accept
450 compensation in exchange for copies. If you distribute a large enough
451 number of copies you must also follow the conditions in section 3.
453 You may also lend copies, under the same conditions stated above, and
454 you may publicly display copies.
457 3. COPYING IN QUANTITY
459 If you publish printed copies of the Document numbering more than 100,
460 and the Document's license notice requires Cover Texts, you must enclose
461 the copies in covers that carry, clearly and legibly, all these Cover
462 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
463 the back cover. Both covers must also clearly and legibly identify
464 you as the publisher of these copies. The front cover must present
465 the full title with all words of the title equally prominent and
466 visible. You may add other material on the covers in addition.
467 Copying with changes limited to the covers, as long as they preserve
468 the title of the Document and satisfy these conditions, can be treated
469 as verbatim copying in other respects.
471 If the required texts for either cover are too voluminous to fit
472 legibly, you should put the first ones listed (as many as fit
473 reasonably) on the actual cover, and continue the rest onto adjacent
476 If you publish or distribute Opaque copies of the Document numbering
477 more than 100, you must either include a machine-readable Transparent
478 copy along with each Opaque copy, or state in or with each Opaque copy
479 a publicly-accessible computer-network location containing a complete
480 Transparent copy of the Document, free of added material, which the
481 general network-using public has access to download anonymously at no
482 charge using public-standard network protocols. If you use the latter
483 option, you must take reasonably prudent steps, when you begin
484 distribution of Opaque copies in quantity, to ensure that this
485 Transparent copy will remain thus accessible at the stated location
486 until at least one year after the last time you distribute an Opaque
487 copy (directly or through your agents or retailers) of that edition to
490 It is requested, but not required, that you contact the authors of the
491 Document well before redistributing any large number of copies, to give
492 them a chance to provide you with an updated version of the Document.
497 You may copy and distribute a Modified Version of the Document under
498 the conditions of sections 2 and 3 above, provided that you release
499 the Modified Version under precisely this License, with the Modified
500 Version filling the role of the Document, thus licensing distribution
501 and modification of the Modified Version to whoever possesses a copy
502 of it. In addition, you must do these things in the Modified Version:
504 A. Use in the Title Page (and on the covers, if any) a title distinct
505 from that of the Document, and from those of previous versions
506 (which should, if there were any, be listed in the History section
507 of the Document). You may use the same title as a previous version
508 if the original publisher of that version gives permission.
509 B. List on the Title Page, as authors, one or more persons or entities
510 responsible for authorship of the modifications in the Modified
511 Version, together with at least five of the principal authors of the
512 Document (all of its principal authors, if it has less than five).
513 C. State on the Title page the name of the publisher of the
514 Modified Version, as the publisher.
515 D. Preserve all the copyright notices of the Document.
516 E. Add an appropriate copyright notice for your modifications
517 adjacent to the other copyright notices.
518 F. Include, immediately after the copyright notices, a license notice
519 giving the public permission to use the Modified Version under the
520 terms of this License, in the form shown in the Addendum below.
521 G. Preserve in that license notice the full lists of Invariant Sections
522 and required Cover Texts given in the Document's license notice.
523 H. Include an unaltered copy of this License.
524 I. Preserve the section entitled "History", and its title, and add to
525 it an item stating at least the title, year, new authors, and
526 publisher of the Modified Version as given on the Title Page. If
527 there is no section entitled "History" in the Document, create one
528 stating the title, year, authors, and publisher of the Document as
529 given on its Title Page, then add an item describing the Modified
530 Version as stated in the previous sentence.
531 J. Preserve the network location, if any, given in the Document for
532 public access to a Transparent copy of the Document, and likewise
533 the network locations given in the Document for previous versions
534 it was based on. These may be placed in the "History" section.
535 You may omit a network location for a work that was published at
536 least four years before the Document itself, or if the original
537 publisher of the version it refers to gives permission.
538 K. In any section entitled "Acknowledgements" or "Dedications",
539 preserve the section's title, and preserve in the section all the
540 substance and tone of each of the contributor acknowledgements
541 and/or dedications given therein.
542 L. Preserve all the Invariant Sections of the Document,
543 unaltered in their text and in their titles. Section numbers
544 or the equivalent are not considered part of the section titles.
545 M. Delete any section entitled "Endorsements". Such a section
546 may not be included in the Modified Version.
547 N. Do not retitle any existing section as "Endorsements"
548 or to conflict in title with any Invariant Section.
550 If the Modified Version includes new front-matter sections or
551 appendices that qualify as Secondary Sections and contain no material
552 copied from the Document, you may at your option designate some or all
553 of these sections as invariant. To do this, add their titles to the
554 list of Invariant Sections in the Modified Version's license notice.
555 These titles must be distinct from any other section titles.
557 You may add a section entitled "Endorsements", provided it contains
558 nothing but endorsements of your Modified Version by various
559 parties--for example, statements of peer review or that the text has
560 been approved by an organization as the authoritative definition of a
563 You may add a passage of up to five words as a Front-Cover Text, and a
564 passage of up to 25 words as a Back-Cover Text, to the end of the list
565 of Cover Texts in the Modified Version. Only one passage of
566 Front-Cover Text and one of Back-Cover Text may be added by (or
567 through arrangements made by) any one entity. If the Document already
568 includes a cover text for the same cover, previously added by you or
569 by arrangement made by the same entity you are acting on behalf of,
570 you may not add another; but you may replace the old one, on explicit
571 permission from the previous publisher that added the old one.
573 The author(s) and publisher(s) of the Document do not by this License
574 give permission to use their names for publicity for or to assert or
575 imply endorsement of any Modified Version.
578 5. COMBINING DOCUMENTS
580 You may combine the Document with other documents released under this
581 License, under the terms defined in section 4 above for modified
582 versions, provided that you include in the combination all of the
583 Invariant Sections of all of the original documents, unmodified, and
584 list them all as Invariant Sections of your combined work in its
587 The combined work need only contain one copy of this License, and
588 multiple identical Invariant Sections may be replaced with a single
589 copy. If there are multiple Invariant Sections with the same name but
590 different contents, make the title of each such section unique by
591 adding at the end of it, in parentheses, the name of the original
592 author or publisher of that section if known, or else a unique number.
593 Make the same adjustment to the section titles in the list of
594 Invariant Sections in the license notice of the combined work.
596 In the combination, you must combine any sections entitled "History"
597 in the various original documents, forming one section entitled
598 "History"; likewise combine any sections entitled "Acknowledgements",
599 and any sections entitled "Dedications". You must delete all sections
600 entitled "Endorsements."
603 6. COLLECTIONS OF DOCUMENTS
605 You may make a collection consisting of the Document and other documents
606 released under this License, and replace the individual copies of this
607 License in the various documents with a single copy that is included in
608 the collection, provided that you follow the rules of this License for
609 verbatim copying of each of the documents in all other respects.
611 You may extract a single document from such a collection, and distribute
612 it individually under this License, provided you insert a copy of this
613 License into the extracted document, and follow this License in all
614 other respects regarding verbatim copying of that document.
617 7. AGGREGATION WITH INDEPENDENT WORKS
619 A compilation of the Document or its derivatives with other separate
620 and independent documents or works, in or on a volume of a storage or
621 distribution medium, does not as a whole count as a Modified Version
622 of the Document, provided no compilation copyright is claimed for the
623 compilation. Such a compilation is called an "aggregate", and this
624 License does not apply to the other self-contained works thus compiled
625 with the Document, on account of their being thus compiled, if they
626 are not themselves derivative works of the Document.
628 If the Cover Text requirement of section 3 is applicable to these
629 copies of the Document, then if the Document is less than one quarter
630 of the entire aggregate, the Document's Cover Texts may be placed on
631 covers that surround only the Document within the aggregate.
632 Otherwise they must appear on covers around the whole aggregate.
637 Translation is considered a kind of modification, so you may
638 distribute translations of the Document under the terms of section 4.
639 Replacing Invariant Sections with translations requires special
640 permission from their copyright holders, but you may include
641 translations of some or all Invariant Sections in addition to the
642 original versions of these Invariant Sections. You may include a
643 translation of this License provided that you also include the
644 original English version of this License. In case of a disagreement
645 between the translation and the original English version of this
646 License, the original English version will prevail.
651 You may not copy, modify, sublicense, or distribute the Document except
652 as expressly provided for under this License. Any other attempt to
653 copy, modify, sublicense or distribute the Document is void, and will
654 automatically terminate your rights under this License. However,
655 parties who have received copies, or rights, from you under this
656 License will not have their licenses terminated so long as such
657 parties remain in full compliance.
660 10. FUTURE REVISIONS OF THIS LICENSE
662 The Free Software Foundation may publish new, revised versions
663 of the GNU Free Documentation License from time to time. Such new
664 versions will be similar in spirit to the present version, but may
665 differ in detail to address new problems or concerns. See
666 http://www.gnu.org/copyleft/.
668 Each version of the License is given a distinguishing version number.
669 If the Document specifies that a particular numbered version of this
670 License "or any later version" applies to it, you have the option of
671 following the terms and conditions either of that specified version or
672 of any later version that has been published (not as a draft) by the
673 Free Software Foundation. If the Document does not specify a version
674 number of this License, you may choose any version ever published (not
675 as a draft) by the Free Software Foundation.
678 ADDENDUM: How to use this License for your documents
680 To use this License in a document you have written, include a copy of
681 the License in the document and put the following copyright and
682 license notices just after the title page:
684 Copyright (c) YEAR YOUR NAME.
685 Permission is granted to copy, distribute and/or modify this document
686 under the terms of the GNU Free Documentation License, Version 1.1
687 or any later version published by the Free Software Foundation;
688 with the Invariant Sections being LIST THEIR TITLES, with the
689 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
690 A copy of the license is included in the section entitled "GNU
691 Free Documentation License".
693 If you have no Invariant Sections, write "with no Invariant Sections"
694 instead of saying which ones are invariant. If you have no
695 Front-Cover Texts, write "no Front-Cover Texts" instead of
696 "Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
698 If your document contains nontrivial examples of program code, we
699 recommend releasing these examples in parallel under your choice of
700 free software license, such as the GNU General Public License,
701 to permit their use in free software.
