6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
11 The licenses for most software are designed to take away your
12 freedom to share and change it. By contrast, the GNU General Public
13 License is intended to guarantee your freedom to share and change free
14 software--to make sure the software is free for all its users. This
15 General Public License applies to most of the Free Software
16 Foundation's software and to any other program whose authors commit to
17 using it. (Some other Free Software Foundation software is covered by
18 the GNU Library General Public License instead.) You can apply it to
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 this service if you wish), that you receive source code or can get it
25 if you want it, that you can change the software or use pieces of it
26 in new free programs; and that you know you can do these things.
28 To protect your rights, we need to make restrictions that forbid
29 anyone to deny you these rights or to ask you to surrender the rights.
30 These restrictions translate to certain responsibilities for you if you
31 distribute copies of the software, or if you modify it.
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must give the recipients all the rights that
35 you have. You must make sure that they, too, receive or can get the
36 source code. And you must show them these terms so they know their
39 We protect your rights with two steps: (1) copyright the software, and
40 (2) offer you this license which gives you legal permission to copy,
41 distribute and/or modify the software.
43 Also, for each author's protection and ours, we want to make certain
44 that everyone understands that there is no warranty for this free
45 software. If the software is modified by someone else and passed on, we
46 want its recipients to know that what they have is not the original, so
47 that any problems introduced by others will not reflect on the original
50 Finally, any free program is threatened constantly by software
51 patents. We wish to avoid the danger that redistributors of a free
52 program will individually obtain patent licenses, in effect making the
53 program proprietary. To prevent this, we have made it clear that any
54 patent must be licensed for everyone's free use or not licensed at all.
56 The precise terms and conditions for copying, distribution and
60 GNU GENERAL PUBLIC LICENSE
61 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
63 0. This License applies to any program or other work which contains
64 a notice placed by the copyright holder saying it may be distributed
65 under the terms of this General Public License. The "Program", below,
66 refers to any such program or work, and a "work based on the Program"
67 means either the Program or any derivative work under copyright law:
68 that is to say, a work containing the Program or a portion of it,
69 either verbatim or with modifications and/or translated into another
70 language. (Hereinafter, translation is included without limitation in
71 the term "modification".) Each licensee is addressed as "you".
73 Activities other than copying, distribution and modification are not
74 covered by this License; they are outside its scope. The act of
75 running the Program is not restricted, and the output from the Program
76 is covered only if its contents constitute a work based on the
77 Program (independent of having been made by running the Program).
78 Whether that is true depends on what the Program does.
80 1. You may copy and distribute verbatim copies of the Program's
81 source code as you receive it, in any medium, provided that you
82 conspicuously and appropriately publish on each copy an appropriate
83 copyright notice and disclaimer of warranty; keep intact all the
84 notices that refer to this License and to the absence of any warranty;
85 and give any other recipients of the Program a copy of this License
86 along with the Program.
88 You may charge a fee for the physical act of transferring a copy, and
89 you may at your option offer warranty protection in exchange for a fee.
91 2. You may modify your copy or copies of the Program or any portion
92 of it, thus forming a work based on the Program, and copy and
93 distribute such modifications or work under the terms of Section 1
94 above, provided that you also meet all of these conditions:
96 a) You must cause the modified files to carry prominent notices
97 stating that you changed the files and the date of any change.
99 b) You must cause any work that you distribute or publish, that in
100 whole or in part contains or is derived from the Program or any
101 part thereof, to be licensed as a whole at no charge to all third
102 parties under the terms of this License.
104 c) If the modified program normally reads commands interactively
105 when run, you must cause it, when started running for such
106 interactive use in the most ordinary way, to print or display an
107 announcement including an appropriate copyright notice and a
108 notice that there is no warranty (or else, saying that you provide
109 a warranty) and that users may redistribute the program under
110 these conditions, and telling the user how to view a copy of this
111 License. (Exception: if the Program itself is interactive but
112 does not normally print such an announcement, your work based on
113 the Program is not required to print an announcement.)
116 These requirements apply to the modified work as a whole. If
117 identifiable sections of that work are not derived from the Program,
118 and can be reasonably considered independent and separate works in
119 themselves, then this License, and its terms, do not apply to those
120 sections when you distribute them as separate works. But when you
121 distribute the same sections as part of a whole which is a work based
122 on the Program, the distribution of the whole must be on the terms of
123 this License, whose permissions for other licensees extend to the
124 entire whole, and thus to each and every part regardless of who wrote it.
126 Thus, it is not the intent of this section to claim rights or contest
127 your rights to work written entirely by you; rather, the intent is to
128 exercise the right to control the distribution of derivative or
129 collective works based on the Program.
131 In addition, mere aggregation of another work not based on the Program
132 with the Program (or with a work based on the Program) on a volume of
133 a storage or distribution medium does not bring the other work under
134 the scope of this License.
136 3. You may copy and distribute the Program (or a work based on it,
137 under Section 2) in object code or executable form under the terms of
138 Sections 1 and 2 above provided that you also do one of the following:
140 a) Accompany it with the complete corresponding machine-readable
141 source code, which must be distributed under the terms of Sections
142 1 and 2 above on a medium customarily used for software interchange; or,
144 b) Accompany it with a written offer, valid for at least three
145 years, to give any third party, for a charge no more than your
146 cost of physically performing source distribution, a complete
147 machine-readable copy of the corresponding source code, to be
148 distributed under the terms of Sections 1 and 2 above on a medium
149 customarily used for software interchange; or,
151 c) Accompany it with the information you received as to the offer
152 to distribute corresponding source code. (This alternative is
153 allowed only for noncommercial distribution and only if you
154 received the program in object code or executable form with such
155 an offer, in accord with Subsection b above.)
157 The source code for a work means the preferred form of the work for
158 making modifications to it. For an executable work, complete source
159 code means all the source code for all modules it contains, plus any
160 associated interface definition files, plus the scripts used to
161 control compilation and installation of the executable. However, as a
162 special exception, the source code distributed need not include
163 anything that is normally distributed (in either source or binary
164 form) with the major components (compiler, kernel, and so on) of the
165 operating system on which the executable runs, unless that component
166 itself accompanies the executable.
168 If distribution of executable or object code is made by offering
169 access to copy from a designated place, then offering equivalent
170 access to copy the source code from the same place counts as
171 distribution of the source code, even though third parties are not
172 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.
233 8. If the distribution and/or use of the Program is restricted in
234 certain countries either by patents or by copyrighted interfaces, the
235 original copyright holder who places the Program under this License
236 may add an explicit geographical distribution limitation excluding
237 those countries, so that distribution is permitted only in or among
238 countries not thus excluded. In such case, this License incorporates
239 the limitation as if written in the body of this License.
241 9. The Free Software Foundation may publish revised and/or new versions
242 of the General Public License from time to time. Such new versions will
243 be similar in spirit to the present version, but may differ in detail to
244 address new problems or concerns.
246 Each version is given a distinguishing version number. If the Program
247 specifies a version number of this License which applies to it and "any
248 later version", you have the option of following the terms and conditions
249 either of that version or of any later version published by the Free
250 Software Foundation. If the Program does not specify a version number of
251 this License, you may choose any version ever published by the Free Software
254 10. If you wish to incorporate parts of the Program into other free
255 programs whose distribution conditions are different, write to the author
256 to ask for permission. For software which is copyrighted by the Free
257 Software Foundation, write to the Free Software Foundation; we sometimes
258 make exceptions for this. Our decision will be guided by the two goals
259 of preserving the free status of all derivatives of our free software and
260 of promoting the sharing and reuse of software generally.
264 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
265 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
266 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
267 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
268 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
269 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
270 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
271 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
272 REPAIR OR CORRECTION.
274 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
275 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
276 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
277 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
278 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
279 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
280 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
281 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
282 POSSIBILITY OF SUCH DAMAGES.
284 END OF TERMS AND CONDITIONS
287 How to Apply These Terms to Your New Programs
289 If you develop a new program, and you want it to be of the greatest
290 possible use to the public, the best way to achieve this is to make it
291 free software which everyone can redistribute and change under these terms.
293 To do so, attach the following notices to the program. It is safest
294 to attach them to the start of each source file to most effectively
295 convey the exclusion of warranty; and each file should have at least
296 the "copyright" line and a pointer to where the full notice is found.
298 <one line to give the program's name and a brief idea of what it does.>
299 Copyright (C) <year> <name of author>
301 This program is free software; you can redistribute it and/or modify
302 it under the terms of the GNU General Public License as published by
303 the Free Software Foundation; either version 2 of the License, or
304 (at your option) any later version.
306 This program is distributed in the hope that it will be useful,
307 but WITHOUT ANY WARRANTY; without even the implied warranty of
308 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
309 GNU General Public License for more details.
311 You should have received a copy of the GNU General Public License
312 along with this program; if not, write to the Free Software
313 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
316 Also add information on how to contact you by electronic and paper mail.
318 If the program is interactive, make it output a short notice like this
319 when it starts in an interactive mode:
321 Gnomovision version 69, Copyright (C) year name of author
322 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
323 This is free software, and you are welcome to redistribute it
324 under certain conditions; type `show c' for details.
326 The hypothetical commands `show w' and `show c' should show the appropriate
327 parts of the General Public License. Of course, the commands you use may
328 be called something other than `show w' and `show c'; they could even be
329 mouse-clicks or menu items--whatever suits your program.
331 You should also get your employer (if you work as a programmer) or your
332 school, if any, to sign a "copyright disclaimer" for the program, if
333 necessary. Here is a sample; alter the names:
335 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
336 `Gnomovision' (which makes passes at compilers) written by James Hacker.

339 Ty Coon, President of Vice
341 This General Public License does not permit incorporating your program into
342 proprietary programs. If your program is a subroutine library, you may
343 consider it more useful to permit linking proprietary applications with the
344 library. If this is what you want to do, use the GNU Library General
345 Public License instead of this License.
349 GNU LESSER GENERAL PUBLIC LICENSE
350 Version 2.1, February 1999
352 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
353 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
354 Everyone is permitted to copy and distribute verbatim copies
355 of this license document, but changing it is not allowed.
357 [This is the first released version of the Lesser GPL. It also counts
358 as the successor of the GNU Library Public License, version 2, hence
359 the version number 2.1.]
363 The licenses for most software are designed to take away your
364 freedom to share and change it. By contrast, the GNU General Public
365 Licenses are intended to guarantee your freedom to share and change
366 free software--to make sure the software is free for all its users.
368 This license, the Lesser General Public License, applies to some
369 specially designated software packages--typically libraries--of the
370 Free Software Foundation and other authors who decide to use it. You
371 can use it too, but we suggest you first think carefully about whether
372 this license or the ordinary General Public License is the better
373 strategy to use in any particular case, based on the explanations below.
375 When we speak of free software, we are referring to freedom of use,
376 not price. Our General Public Licenses are designed to make sure that
377 you have the freedom to distribute copies of free software (and charge
378 for this service if you wish); that you receive source code or can get
379 it if you want it; that you can change the software and use pieces of
380 it in new free programs; and that you are informed that you can do
383 To protect your rights, we need to make restrictions that forbid
384 distributors to deny you these rights or to ask you to surrender these
385 rights. These restrictions translate to certain responsibilities for
386 you if you distribute copies of the library or if you modify it.
388 For example, if you distribute copies of the library, whether gratis
389 or for a fee, you must give the recipients all the rights that we gave
390 you. You must make sure that they, too, receive or can get the source
391 code. If you link other code with the library, you must provide
392 complete object files to the recipients, so that they can relink them
393 with the library after making changes to the library and recompiling
394 it. And you must show them these terms so they know their rights.
396 We protect your rights with a two-step method: (1) we copyright the
397 library, and (2) we offer you this license, which gives you legal
398 permission to copy, distribute and/or modify the library.
400 To protect each distributor, we want to make it very clear that
401 there is no warranty for the free library. Also, if the library is
402 modified by someone else and passed on, the recipients should know
403 that what they have is not the original version, so that the original
404 author's reputation will not be affected by problems that might be
405 introduced by others.
407 Finally, software patents pose a constant threat to the existence of
408 any free program. We wish to make sure that a company cannot
409 effectively restrict the users of a free program by obtaining a
410 restrictive license from a patent holder. Therefore, we insist that
411 any patent license obtained for a version of the library must be
412 consistent with the full freedom of use specified in this license.
414 Most GNU software, including some libraries, is covered by the
415 ordinary GNU General Public License. This license, the GNU Lesser
416 General Public License, applies to certain designated libraries, and
417 is quite different from the ordinary General Public License. We use
418 this license for certain libraries in order to permit linking those
419 libraries into non-free programs.
421 When a program is linked with a library, whether statically or using
422 a shared library, the combination of the two is legally speaking a
423 combined work, a derivative of the original library. The ordinary
424 General Public License therefore permits such linking only if the
425 entire combination fits its criteria of freedom. The Lesser General
426 Public License permits more lax criteria for linking other code with
429 We call this license the "Lesser" General Public License because it
430 does Less to protect the user's freedom than the ordinary General
431 Public License. It also provides other free software developers Less
432 of an advantage over competing non-free programs. These disadvantages
433 are the reason we use the ordinary General Public License for many
434 libraries. However, the Lesser license provides advantages in certain
435 special circumstances.
437 For example, on rare occasions, there may be a special need to
438 encourage the widest possible use of a certain library, so that it becomes
439 a de-facto standard. To achieve this, non-free programs must be
440 allowed to use the library. A more frequent case is that a free
441 library does the same job as widely used non-free libraries. In this
442 case, there is little to gain by limiting the free library to free
443 software only, so we use the Lesser General Public License.
445 In other cases, permission to use a particular library in non-free
446 programs enables a greater number of people to use a large body of
447 free software. For example, permission to use the GNU C Library in
448 non-free programs enables many more people to use the whole GNU
449 operating system, as well as its variant, the GNU/Linux operating
452 Although the Lesser General Public License is Less protective of the
453 users' freedom, it does ensure that the user of a program that is
454 linked with the Library has the freedom and the wherewithal to run
455 that program using a modified version of the Library.
457 The precise terms and conditions for copying, distribution and
458 modification follow. Pay close attention to the difference between a
459 "work based on the library" and a "work that uses the library". The
460 former contains code derived from the library, whereas the latter must
461 be combined with the library in order to run.
463 GNU LESSER GENERAL PUBLIC LICENSE
464 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
466 0. This License Agreement applies to any software library or other
467 program which contains a notice placed by the copyright holder or
468 other authorized party saying it may be distributed under the terms of
469 this Lesser General Public License (also called "this License").
470 Each licensee is addressed as "you".
472 A "library" means a collection of software functions and/or data
473 prepared so as to be conveniently linked with application programs
474 (which use some of those functions and data) to form executables.
476 The "Library", below, refers to any such software library or work
477 which has been distributed under these terms. A "work based on the
478 Library" means either the Library or any derivative work under
479 copyright law: that is to say, a work containing the Library or a
480 portion of it, either verbatim or with modifications and/or translated
481 straightforwardly into another language. (Hereinafter, translation is
482 included without limitation in the term "modification".)
484 "Source code" for a work means the preferred form of the work for
485 making modifications to it. For a library, complete source code means
486 all the source code for all modules it contains, plus any associated
487 interface definition files, plus the scripts used to control compilation
488 and installation of the library.
490 Activities other than copying, distribution and modification are not
491 covered by this License; they are outside its scope. The act of
492 running a program using the Library is not restricted, and output from
493 such a program is covered only if its contents constitute a work based
494 on the Library (independent of the use of the Library in a tool for
495 writing it). Whether that is true depends on what the Library does
496 and what the program that uses the Library does.
498 1. You may copy and distribute verbatim copies of the Library's
499 complete source code as you receive it, in any medium, provided that
500 you conspicuously and appropriately publish on each copy an
501 appropriate copyright notice and disclaimer of warranty; keep intact
502 all the notices that refer to this License and to the absence of any
503 warranty; and distribute a copy of this License along with the
506 You may charge a fee for the physical act of transferring a copy,
507 and you may at your option offer warranty protection in exchange for a
510 2. You may modify your copy or copies of the Library or any portion
511 of it, thus forming a work based on the Library, and copy and
512 distribute such modifications or work under the terms of Section 1
513 above, provided that you also meet all of these conditions:
515 a) The modified work must itself be a software library.
517 b) You must cause the files modified to carry prominent notices
518 stating that you changed the files and the date of any change.
520 c) You must cause the whole of the work to be licensed at no
521 charge to all third parties under the terms of this License.
523 d) If a facility in the modified Library refers to a function or a
524 table of data to be supplied by an application program that uses
525 the facility, other than as an argument passed when the facility
526 is invoked, then you must make a good faith effort to ensure that,
527 in the event an application does not supply such function or
528 table, the facility still operates, and performs whatever part of
529 its purpose remains meaningful.
531 (For example, a function in a library to compute square roots has
532 a purpose that is entirely well-defined independent of the
533 application. Therefore, Subsection 2d requires that any
534 application-supplied function or table used by this function must
535 be optional: if the application does not supply it, the square
536 root function must still compute square roots.)
538 These requirements apply to the modified work as a whole. If
539 identifiable sections of that work are not derived from the Library,
540 and can be reasonably considered independent and separate works in
541 themselves, then this License, and its terms, do not apply to those
542 sections when you distribute them as separate works. But when you
543 distribute the same sections as part of a whole which is a work based
544 on the Library, the distribution of the whole must be on the terms of
545 this License, whose permissions for other licensees extend to the
546 entire whole, and thus to each and every part regardless of who wrote
549 Thus, it is not the intent of this section to claim rights or contest
550 your rights to work written entirely by you; rather, the intent is to
551 exercise the right to control the distribution of derivative or
552 collective works based on the Library.
554 In addition, mere aggregation of another work not based on the Library
555 with the Library (or with a work based on the Library) on a volume of
556 a storage or distribution medium does not bring the other work under
557 the scope of this License.
559 3. You may opt to apply the terms of the ordinary GNU General Public
560 License instead of this License to a given copy of the Library. To do
561 this, you must alter all the notices that refer to this License, so
562 that they refer to the ordinary GNU General Public License, version 2,
563 instead of to this License. (If a newer version than version 2 of the
564 ordinary GNU General Public License has appeared, then you can specify
565 that version instead if you wish.) Do not make any other change in
568 Once this change is made in a given copy, it is irreversible for
569 that copy, so the ordinary GNU General Public License applies to all
570 subsequent copies and derivative works made from that copy.
572 This option is useful when you wish to copy part of the code of
573 the Library into a program that is not a library.
575 4. You may copy and distribute the Library (or a portion or
576 derivative of it, under Section 2) in object code or executable form
577 under the terms of Sections 1 and 2 above provided that you accompany
578 it with the complete corresponding machine-readable source code, which
579 must be distributed under the terms of Sections 1 and 2 above on a
580 medium customarily used for software interchange.
582 If distribution of object code is made by offering access to copy
583 from a designated place, then offering equivalent access to copy the
584 source code from the same place satisfies the requirement to
585 distribute the source code, even though third parties are not
586 compelled to copy the source along with the object code.
588 5. A program that contains no derivative of any portion of the
589 Library, but is designed to work with the Library by being compiled or
590 linked with it, is called a "work that uses the Library". Such a
591 work, in isolation, is not a derivative work of the Library, and
592 therefore falls outside the scope of this License.
594 However, linking a "work that uses the Library" with the Library
595 creates an executable that is a derivative of the Library (because it
596 contains portions of the Library), rather than a "work that uses the
597 library". The executable is therefore covered by this License.
598 Section 6 states terms for distribution of such executables.
600 When a "work that uses the Library" uses material from a header file
601 that is part of the Library, the object code for the work may be a
602 derivative work of the Library even though the source code is not.
603 Whether this is true is especially significant if the work can be
604 linked without the Library, or if the work is itself a library. The
605 threshold for this to be true is not precisely defined by law.
607 If such an object file uses only numerical parameters, data
608 structure layouts and accessors, and small macros and small inline
609 functions (ten lines or less in length), then the use of the object
610 file is unrestricted, regardless of whether it is legally a derivative
611 work. (Executables containing this object code plus portions of the
612 Library will still fall under Section 6.)
614 Otherwise, if the work is a derivative of the Library, you may
615 distribute the object code for the work under the terms of Section 6.
616 Any executables containing that work also fall under Section 6,
617 whether or not they are linked directly with the Library itself.
619 6. As an exception to the Sections above, you may also combine or
620 link a "work that uses the Library" with the Library to produce a
621 work containing portions of the Library, and distribute that work
622 under terms of your choice, provided that the terms permit
623 modification of the work for the customer's own use and reverse
624 engineering for debugging such modifications.
626 You must give prominent notice with each copy of the work that the
627 Library is used in it and that the Library and its use are covered by
628 this License. You must supply a copy of this License. If the work
629 during execution displays copyright notices, you must include the
630 copyright notice for the Library among them, as well as a reference
631 directing the user to the copy of this License. Also, you must do one
634 a) Accompany the work with the complete corresponding
635 machine-readable source code for the Library including whatever
636 changes were used in the work (which must be distributed under
637 Sections 1 and 2 above); and, if the work is an executable linked
638 with the Library, with the complete machine-readable "work that
639 uses the Library", as object code and/or source code, so that the
640 user can modify the Library and then relink to produce a modified
641 executable containing the modified Library. (It is understood
642 that the user who changes the contents of definitions files in the
643 Library will not necessarily be able to recompile the application
644 to use the modified definitions.)
646 b) Use a suitable shared library mechanism for linking with the
647 Library. A suitable mechanism is one that (1) uses at run time a
648 copy of the library already present on the user's computer system,
649 rather than copying library functions into the executable, and (2)
650 will operate properly with a modified version of the library, if
651 the user installs one, as long as the modified version is
652 interface-compatible with the version that the work was made with.
654 c) Accompany the work with a written offer, valid for at
655 least three years, to give the same user the materials
656 specified in Subsection 6a, above, for a charge no more
657 than the cost of performing this distribution.
659 d) If distribution of the work is made by offering access to copy
660 from a designated place, offer equivalent access to copy the above
661 specified materials from the same place.
663 e) Verify that the user has already received a copy of these
664 materials or that you have already sent this user a copy.
666 For an executable, the required form of the "work that uses the
667 Library" must include any data and utility programs needed for
668 reproducing the executable from it. However, as a special exception,
669 the materials to be distributed need not include anything that is
670 normally distributed (in either source or binary form) with the major
671 components (compiler, kernel, and so on) of the operating system on
672 which the executable runs, unless that component itself accompanies
675 It may happen that this requirement contradicts the license
676 restrictions of other proprietary libraries that do not normally
677 accompany the operating system. Such a contradiction means you cannot
678 use both them and the Library together in an executable that you
681 7. You may place library facilities that are a work based on the
682 Library side-by-side in a single library together with other library
683 facilities not covered by this License, and distribute such a combined
684 library, provided that the separate distribution of the work based on
685 the Library and of the other library facilities is otherwise
686 permitted, and provided that you do these two things:
688 a) Accompany the combined library with a copy of the same work
689 based on the Library, uncombined with any other library
690 facilities. This must be distributed under the terms of the
693 b) Give prominent notice with the combined library of the fact
694 that part of it is a work based on the Library, and explaining
695 where to find the accompanying uncombined form of the same work.
697 8. You may not copy, modify, sublicense, link with, or distribute
698 the Library except as expressly provided under this License. Any
699 attempt otherwise to copy, modify, sublicense, link with, or
700 distribute the Library is void, and will automatically terminate your
701 rights under this License. However, parties who have received copies,
702 or rights, from you under this License will not have their licenses
703 terminated so long as such parties remain in full compliance.
705 9. You are not required to accept this License, since you have not
706 signed it. However, nothing else grants you permission to modify or
707 distribute the Library or its derivative works. These actions are
708 prohibited by law if you do not accept this License. Therefore, by
709 modifying or distributing the Library (or any work based on the
710 Library), you indicate your acceptance of this License to do so, and
711 all its terms and conditions for copying, distributing or modifying
712 the Library or works based on it.
714 10. Each time you redistribute the Library (or any work based on the
715 Library), the recipient automatically receives a license from the
716 original licensor to copy, distribute, link with or modify the Library
717 subject to these terms and conditions. You may not impose any further
718 restrictions on the recipients' exercise of the rights granted herein.
719 You are not responsible for enforcing compliance by third parties with
722 11. If, as a consequence of a court judgment or allegation of patent
723 infringement or for any other reason (not limited to patent issues),
724 conditions are imposed on you (whether by court order, agreement or
725 otherwise) that contradict the conditions of this License, they do not
726 excuse you from the conditions of this License. If you cannot
727 distribute so as to satisfy simultaneously your obligations under this
728 License and any other pertinent obligations, then as a consequence you
729 may not distribute the Library at all. For example, if a patent
730 license would not permit royalty-free redistribution of the Library by
731 all those who receive copies directly or indirectly through you, then
732 the only way you could satisfy both it and this License would be to
733 refrain entirely from distribution of the Library.
735 If any portion of this section is held invalid or unenforceable under any
736 particular circumstance, the balance of the section is intended to apply,
737 and the section as a whole is intended to apply in other circumstances.
739 It is not the purpose of this section to induce you to infringe any
740 patents or other property right claims or to contest validity of any
741 such claims; this section has the sole purpose of protecting the
742 integrity of the free software distribution system which is
743 implemented by public license practices. Many people have made
744 generous contributions to the wide range of software distributed
745 through that system in reliance on consistent application of that
746 system; it is up to the author/donor to decide if he or she is willing
747 to distribute software through any other system and a licensee cannot
750 This section is intended to make thoroughly clear what is believed to
751 be a consequence of the rest of this License.
753 12. If the distribution and/or use of the Library is restricted in
754 certain countries either by patents or by copyrighted interfaces, the
755 original copyright holder who places the Library under this License may add
756 an explicit geographical distribution limitation excluding those countries,
757 so that distribution is permitted only in or among countries not thus
758 excluded. In such case, this License incorporates the limitation as if
759 written in the body of this License.
761 13. The Free Software Foundation may publish revised and/or new
762 versions of the Lesser General Public License from time to time.
763 Such new versions will be similar in spirit to the present version,
764 but may differ in detail to address new problems or concerns.
766 Each version is given a distinguishing version number. If the Library
767 specifies a version number of this License which applies to it and
768 "any later version", you have the option of following the terms and
769 conditions either of that version or of any later version published by
770 the Free Software Foundation. If the Library does not specify a
771 license version number, you may choose any version ever published by
772 the Free Software Foundation.
774 14. If you wish to incorporate parts of the Library into other free
775 programs whose distribution conditions are incompatible with these,
776 write to the author to ask for permission. For software which is
777 copyrighted by the Free Software Foundation, write to the Free
778 Software Foundation; we sometimes make exceptions for this. Our
779 decision will be guided by the two goals of preserving the free status
780 of all derivatives of our free software and of promoting the sharing
781 and reuse of software generally.
785 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
786 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
787 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
788 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
789 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
790 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
791 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
792 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
793 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
795 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
796 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
797 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
798 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
799 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
800 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
801 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
802 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
803 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
806 END OF TERMS AND CONDITIONS
808 How to Apply These Terms to Your New Libraries
810 If you develop a new library, and you want it to be of the greatest
811 possible use to the public, we recommend making it free software that
812 everyone can redistribute and change. You can do so by permitting
813 redistribution under these terms (or, alternatively, under the terms of the
814 ordinary General Public License).
816 To apply these terms, attach the following notices to the library. It is
817 safest to attach them to the start of each source file to most effectively
818 convey the exclusion of warranty; and each file should have at least the
819 "copyright" line and a pointer to where the full notice is found.
821 <one line to give the library's name and a brief idea of what it does.>
822 Copyright (C) <year> <name of author>
824 This library is free software; you can redistribute it and/or
825 modify it under the terms of the GNU Lesser General Public
826 License as published by the Free Software Foundation; either
827 version 2.1 of the License, or (at your option) any later version.
829 This library is distributed in the hope that it will be useful,
830 but WITHOUT ANY WARRANTY; without even the implied warranty of
831 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
832 Lesser General Public License for more details.
834 You should have received a copy of the GNU Lesser General Public
835 License along with this library; if not, write to the Free Software
836 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
838 Also add information on how to contact you by electronic and paper mail.
840 You should also get your employer (if you work as a programmer) or your
841 school, if any, to sign a "copyright disclaimer" for the library, if
842 necessary. Here is a sample; alter the names:
844 Yoyodyne, Inc., hereby disclaims all copyright interest in the
845 library `Frob' (a library for tweaking knobs) written by James Random Hacker.

854 Version 1.3, 3 November 2008
857 Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
859 Everyone is permitted to copy and distribute verbatim copies
860 of this license document, but changing it is not allowed.
864 The purpose of this License is to make a manual, textbook, or other
865 functional and useful document "free" in the sense of freedom: to
866 assure everyone the effective freedom to copy and redistribute it,
867 with or without modifying it, either commercially or noncommercially.
868 Secondarily, this License preserves for the author and publisher a way
869 to get credit for their work, while not being considered responsible
870 for modifications made by others.
872 This License is a kind of "copyleft", which means that derivative
873 works of the document must themselves be free in the same sense. It
874 complements the GNU General Public License, which is a copyleft
875 license designed for free software.
877 We have designed this License in order to use it for manuals for free
878 software, because free software needs free documentation: a free
879 program should come with manuals providing the same freedoms that the
880 software does. But this License is not limited to software manuals;
881 it can be used for any textual work, regardless of subject matter or
882 whether it is published as a printed book. We recommend this License
883 principally for works whose purpose is instruction or reference.
886 1. APPLICABILITY AND DEFINITIONS
888 This License applies to any manual or other work, in any medium, that
889 contains a notice placed by the copyright holder saying it can be
890 distributed under the terms of this License. Such a notice grants a
891 world-wide, royalty-free license, unlimited in duration, to use that
892 work under the conditions stated herein. The "Document", below,
893 refers to any such manual or work. Any member of the public is a
894 licensee, and is addressed as "you". You accept the license if you
895 copy, modify or distribute the work in a way requiring permission
898 A "Modified Version" of the Document means any work containing the
899 Document or a portion of it, either copied verbatim, or with
900 modifications and/or translated into another language.
902 A "Secondary Section" is a named appendix or a front-matter section of
903 the Document that deals exclusively with the relationship of the
904 publishers or authors of the Document to the Document's overall
905 subject (or to related matters) and contains nothing that could fall
906 directly within that overall subject. (Thus, if the Document is in
907 part a textbook of mathematics, a Secondary Section may not explain
908 any mathematics.) The relationship could be a matter of historical
909 connection with the subject or with related matters, or of legal,
910 commercial, philosophical, ethical or political position regarding
913 The "Invariant Sections" are certain Secondary Sections whose titles
914 are designated, as being those of Invariant Sections, in the notice
915 that says that the Document is released under this License. If a
916 section does not fit the above definition of Secondary then it is not
917 allowed to be designated as Invariant. The Document may contain zero
918 Invariant Sections. If the Document does not identify any Invariant
919 Sections then there are none.
921 The "Cover Texts" are certain short passages of text that are listed,
922 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
923 the Document is released under this License. A Front-Cover Text may
924 be at most 5 words, and a Back-Cover Text may be at most 25 words.
926 A "Transparent" copy of the Document means a machine-readable copy,
927 represented in a format whose specification is available to the
928 general public, that is suitable for revising the document
929 straightforwardly with generic text editors or (for images composed of
930 pixels) generic paint programs or (for drawings) some widely available
931 drawing editor, and that is suitable for input to text formatters or
932 for automatic translation to a variety of formats suitable for input
933 to text formatters. A copy made in an otherwise Transparent file
934 format whose markup, or absence of markup, has been arranged to thwart
935 or discourage subsequent modification by readers is not Transparent.
936 An image format is not Transparent if used for any substantial amount
937 of text. A copy that is not "Transparent" is called "Opaque".
939 Examples of suitable formats for Transparent copies include plain
940 ASCII without markup, Texinfo input format, LaTeX input format, SGML
941 or XML using a publicly available DTD, and standard-conforming simple
942 HTML, PostScript or PDF designed for human modification. Examples of
943 transparent image formats include PNG, XCF and JPG. Opaque formats
944 include proprietary formats that can be read and edited only by
945 proprietary word processors, SGML or XML for which the DTD and/or
946 processing tools are not generally available, and the
947 machine-generated HTML, PostScript or PDF produced by some word
948 processors for output purposes only.
950 The "Title Page" means, for a printed book, the title page itself,
951 plus such following pages as are needed to hold, legibly, the material
952 this License requires to appear in the title page. For works in
953 formats which do not have any title page as such, "Title Page" means
954 the text near the most prominent appearance of the work's title,
955 preceding the beginning of the body of the text.
957 The "publisher" means any person or entity that distributes copies of
958 the Document to the public.
960 A section "Entitled XYZ" means a named subunit of the Document whose
961 title either is precisely XYZ or contains XYZ in parentheses following
962 text that translates XYZ in another language. (Here XYZ stands for a
963 specific section name mentioned below, such as "Acknowledgements",
964 "Dedications", "Endorsements", or "History".) To "Preserve the Title"
965 of such a section when you modify the Document means that it remains a
966 section "Entitled XYZ" according to this definition.
968 The Document may include Warranty Disclaimers next to the notice which
969 states that this License applies to the Document. These Warranty
970 Disclaimers are considered to be included by reference in this
971 License, but only as regards disclaiming warranties: any other
972 implication that these Warranty Disclaimers may have is void and has
973 no effect on the meaning of this License.
977 You may copy and distribute the Document in any medium, either
978 commercially or noncommercially, provided that this License, the
979 copyright notices, and the license notice saying this License applies
980 to the Document are reproduced in all copies, and that you add no
981 other conditions whatsoever to those of this License. You may not use
982 technical measures to obstruct or control the reading or further
983 copying of the copies you make or distribute. However, you may accept
984 compensation in exchange for copies. If you distribute a large enough
985 number of copies you must also follow the conditions in section 3.
987 You may also lend copies, under the same conditions stated above, and
988 you may publicly display copies.
991 3. COPYING IN QUANTITY
993 If you publish printed copies (or copies in media that commonly have
994 printed covers) of the Document, numbering more than 100, and the
995 Document's license notice requires Cover Texts, you must enclose the
996 copies in covers that carry, clearly and legibly, all these Cover
997 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
998 the back cover. Both covers must also clearly and legibly identify
999 you as the publisher of these copies. The front cover must present
1000 the full title with all words of the title equally prominent and
1001 visible. You may add other material on the covers in addition.
1002 Copying with changes limited to the covers, as long as they preserve
1003 the title of the Document and satisfy these conditions, can be treated
1004 as verbatim copying in other respects.
1006 If the required texts for either cover are too voluminous to fit
1007 legibly, you should put the first ones listed (as many as fit
1008 reasonably) on the actual cover, and continue the rest onto adjacent
1011 If you publish or distribute Opaque copies of the Document numbering
1012 more than 100, you must either include a machine-readable Transparent
1013 copy along with each Opaque copy, or state in or with each Opaque copy
1014 a computer-network location from which the general network-using
1015 public has access to download using public-standard network protocols
1016 a complete Transparent copy of the Document, free of added material.
1017 If you use the latter option, you must take reasonably prudent steps,
1018 when you begin distribution of Opaque copies in quantity, to ensure
1019 that this Transparent copy will remain thus accessible at the stated
1020 location until at least one year after the last time you distribute an
1021 Opaque copy (directly or through your agents or retailers) of that
1022 edition to the public.
1024 It is requested, but not required, that you contact the authors of the
1025 Document well before redistributing any large number of copies, to
1026 give them a chance to provide you with an updated version of the
1032 You may copy and distribute a Modified Version of the Document under
1033 the conditions of sections 2 and 3 above, provided that you release
1034 the Modified Version under precisely this License, with the Modified
1035 Version filling the role of the Document, thus licensing distribution
1036 and modification of the Modified Version to whoever possesses a copy
1037 of it. In addition, you must do these things in the Modified Version:
1039 A. Use in the Title Page (and on the covers, if any) a title distinct
1040 from that of the Document, and from those of previous versions
1041 (which should, if there were any, be listed in the History section
1042 of the Document). You may use the same title as a previous version
1043 if the original publisher of that version gives permission.
1044 B. List on the Title Page, as authors, one or more persons or entities
1045 responsible for authorship of the modifications in the Modified
1046 Version, together with at least five of the principal authors of the
1047 Document (all of its principal authors, if it has fewer than five),
1048 unless they release you from this requirement.
1049 C. State on the Title page the name of the publisher of the
1050 Modified Version, as the publisher.
1051 D. Preserve all the copyright notices of the Document.
1052 E. Add an appropriate copyright notice for your modifications
1053 adjacent to the other copyright notices.
1054 F. Include, immediately after the copyright notices, a license notice
1055 giving the public permission to use the Modified Version under the
1056 terms of this License, in the form shown in the Addendum below.
1057 G. Preserve in that license notice the full lists of Invariant Sections
1058 and required Cover Texts given in the Document's license notice.
1059 H. Include an unaltered copy of this License.
1060 I. Preserve the section Entitled "History", Preserve its Title, and add
1061 to it an item stating at least the title, year, new authors, and
1062 publisher of the Modified Version as given on the Title Page. If
1063 there is no section Entitled "History" in the Document, create one
1064 stating the title, year, authors, and publisher of the Document as
1065 given on its Title Page, then add an item describing the Modified
1066 Version as stated in the previous sentence.
1067 J. Preserve the network location, if any, given in the Document for
1068 public access to a Transparent copy of the Document, and likewise
1069 the network locations given in the Document for previous versions
1070 it was based on. These may be placed in the "History" section.
1071 You may omit a network location for a work that was published at
1072 least four years before the Document itself, or if the original
1073 publisher of the version it refers to gives permission.
1074 K. For any section Entitled "Acknowledgements" or "Dedications",
1075 Preserve the Title of the section, and preserve in the section all
1076 the substance and tone of each of the contributor acknowledgements
1077 and/or dedications given therein.
1078 L. Preserve all the Invariant Sections of the Document,
1079 unaltered in their text and in their titles. Section numbers
1080 or the equivalent are not considered part of the section titles.
1081 M. Delete any section Entitled "Endorsements". Such a section
1082 may not be included in the Modified Version.
1083 N. Do not retitle any existing section to be Entitled "Endorsements"
1084 or to conflict in title with any Invariant Section.
1085 O. Preserve any Warranty Disclaimers.
1087 If the Modified Version includes new front-matter sections or
1088 appendices that qualify as Secondary Sections and contain no material
1089 copied from the Document, you may at your option designate some or all
1090 of these sections as invariant. To do this, add their titles to the
1091 list of Invariant Sections in the Modified Version's license notice.
1092 These titles must be distinct from any other section titles.
1094 You may add a section Entitled "Endorsements", provided it contains
1095 nothing but endorsements of your Modified Version by various
1096 parties--for example, statements of peer review or that the text has
1097 been approved by an organization as the authoritative definition of a
1100 You may add a passage of up to five words as a Front-Cover Text, and a
1101 passage of up to 25 words as a Back-Cover Text, to the end of the list
1102 of Cover Texts in the Modified Version. Only one passage of
1103 Front-Cover Text and one of Back-Cover Text may be added by (or
1104 through arrangements made by) any one entity. If the Document already
1105 includes a cover text for the same cover, previously added by you or
1106 by arrangement made by the same entity you are acting on behalf of,
1107 you may not add another; but you may replace the old one, on explicit
1108 permission from the previous publisher that added the old one.
1110 The author(s) and publisher(s) of the Document do not by this License
1111 give permission to use their names for publicity for or to assert or
1112 imply endorsement of any Modified Version.
1115 5. COMBINING DOCUMENTS
1117 You may combine the Document with other documents released under this
1118 License, under the terms defined in section 4 above for modified
1119 versions, provided that you include in the combination all of the
1120 Invariant Sections of all of the original documents, unmodified, and
1121 list them all as Invariant Sections of your combined work in its
1122 license notice, and that you preserve all their Warranty Disclaimers.
1124 The combined work need only contain one copy of this License, and
1125 multiple identical Invariant Sections may be replaced with a single
1126 copy. If there are multiple Invariant Sections with the same name but
1127 different contents, make the title of each such section unique by
1128 adding at the end of it, in parentheses, the name of the original
1129 author or publisher of that section if known, or else a unique number.
1130 Make the same adjustment to the section titles in the list of
1131 Invariant Sections in the license notice of the combined work.
1133 In the combination, you must combine any sections Entitled "History"
1134 in the various original documents, forming one section Entitled
1135 "History"; likewise combine any sections Entitled "Acknowledgements",
1136 and any sections Entitled "Dedications". You must delete all sections
1137 Entitled "Endorsements".
1140 6. COLLECTIONS OF DOCUMENTS
1142 You may make a collection consisting of the Document and other
1143 documents released under this License, and replace the individual
1144 copies of this License in the various documents with a single copy
1145 that is included in the collection, provided that you follow the rules
1146 of this License for verbatim copying of each of the documents in all
1149 You may extract a single document from such a collection, and
1150 distribute it individually under this License, provided you insert a
1151 copy of this License into the extracted document, and follow this
1152 License in all other respects regarding verbatim copying of that
1156 7. AGGREGATION WITH INDEPENDENT WORKS
1158 A compilation of the Document or its derivatives with other separate
1159 and independent documents or works, in or on a volume of a storage or
1160 distribution medium, is called an "aggregate" if the copyright
1161 resulting from the compilation is not used to limit the legal rights
1162 of the compilation's users beyond what the individual works permit.
1163 When the Document is included in an aggregate, this License does not
1164 apply to the other works in the aggregate which are not themselves
1165 derivative works of the Document.
1167 If the Cover Text requirement of section 3 is applicable to these
1168 copies of the Document, then if the Document is less than one half of
1169 the entire aggregate, the Document's Cover Texts may be placed on
1170 covers that bracket the Document within the aggregate, or the
1171 electronic equivalent of covers if the Document is in electronic form.
1172 Otherwise they must appear on printed covers that bracket the whole
1178 Translation is considered a kind of modification, so you may
1179 distribute translations of the Document under the terms of section 4.
1180 Replacing Invariant Sections with translations requires special
1181 permission from their copyright holders, but you may include
1182 translations of some or all Invariant Sections in addition to the
1183 original versions of these Invariant Sections. You may include a
1184 translation of this License, and all the license notices in the
1185 Document, and any Warranty Disclaimers, provided that you also include
1186 the original English version of this License and the original versions
1187 of those notices and disclaimers. In case of a disagreement between
1188 the translation and the original version of this License or a notice
1189 or disclaimer, the original version will prevail.
1191 If a section in the Document is Entitled "Acknowledgements",
1192 "Dedications", or "History", the requirement (section 4) to Preserve
1193 its Title (section 1) will typically require changing the actual
1199 You may not copy, modify, sublicense, or distribute the Document
1200 except as expressly provided under this License. Any attempt
1201 otherwise to copy, modify, sublicense, or distribute it is void, and
1202 will automatically terminate your rights under this License.
1204 However, if you cease all violation of this License, then your license
1205 from a particular copyright holder is reinstated (a) provisionally,
1206 unless and until the copyright holder explicitly and finally
1207 terminates your license, and (b) permanently, if the copyright holder
1208 fails to notify you of the violation by some reasonable means prior to
1209 60 days after the cessation.
1211 Moreover, your license from a particular copyright holder is
1212 reinstated permanently if the copyright holder notifies you of the
1213 violation by some reasonable means, this is the first time you have
1214 received notice of violation of this License (for any work) from that
1215 copyright holder, and you cure the violation prior to 30 days after
1216 your receipt of the notice.
1218 Termination of your rights under this section does not terminate the
1219 licenses of parties who have received copies or rights from you under
1220 this License. If your rights have been terminated and not permanently
1221 reinstated, receipt of a copy of some or all of the same material does
1222 not give you any rights to use it.
1225 10. FUTURE REVISIONS OF THIS LICENSE
1227 The Free Software Foundation may publish new, revised versions of the
1228 GNU Free Documentation License from time to time. Such new versions
1229 will be similar in spirit to the present version, but may differ in
1230 detail to address new problems or concerns. See
1231 http://www.gnu.org/copyleft/.
1233 Each version of the License is given a distinguishing version number.
1234 If the Document specifies that a particular numbered version of this
1235 License "or any later version" applies to it, you have the option of
1236 following the terms and conditions either of that specified version or
1237 of any later version that has been published (not as a draft) by the
1238 Free Software Foundation. If the Document does not specify a version
1239 number of this License, you may choose any version ever published (not
1240 as a draft) by the Free Software Foundation. If the Document
1241 specifies that a proxy can decide which future versions of this
1242 License can be used, that proxy's public statement of acceptance of a
1243 version permanently authorizes you to choose that version for the
1248 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
1249 World Wide Web server that publishes copyrightable works and also
1250 provides prominent facilities for anybody to edit those works. A
1251 public wiki that anybody can edit is an example of such a server. A
1252 "Massive Multiauthor Collaboration" (or "MMC") contained in the site
1253 means any set of copyrightable works thus published on the MMC site.
1255 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
1256 license published by Creative Commons Corporation, a not-for-profit
1257 corporation with a principal place of business in San Francisco,
1258 California, as well as future copyleft versions of that license
1259 published by that same organization.
1261 "Incorporate" means to publish or republish a Document, in whole or in
1262 part, as part of another Document.
1264 An MMC is "eligible for relicensing" if it is licensed under this
1265 License, and if all works that were first published under this License
1266 somewhere other than this MMC, and subsequently incorporated in whole or
1267 in part into the MMC, (1) had no cover texts or invariant sections, and
1268 (2) were thus incorporated prior to November 1, 2008.
1270 The operator of an MMC Site may republish an MMC contained in the site
1271 under CC-BY-SA on the same site at any time before August 1, 2009,
1272 provided the MMC is eligible for relicensing.
1275 ADDENDUM: How to use this License for your documents
1277 To use this License in a document you have written, include a copy of
1278 the License in the document and put the following copyright and
1279 license notices just after the title page:

1286 A copy of the license is included in the section entitled "GNU
1287 Free Documentation License".
1289 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
1290 replace the "with...Texts." line with this:
1292 with the Invariant Sections being LIST THEIR TITLES, with the
1293 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
1295 If you have Invariant Sections without Cover Texts, or some other
1296 combination of the three, merge those two alternatives to suit the
1299 If your document contains nontrivial examples of program code, we
1300 recommend releasing these examples in parallel under your choice of
1301 free software license, such as the GNU General Public License,
1302 to permit their use in free software.
