11 Everyone is permitted to copy and distribute verbatim copies
12 of this license document, but changing it is not allowed.
16 The licenses for most software are designed to take away your
17 freedom to share and change it. By contrast, the GNU General Public
18 License is intended to guarantee your freedom to share and change free
19 software--to make sure the software is free for all its users. This
20 General Public License applies to most of the Free Software
21 Foundation's software and to any other program whose authors commit to
22 using it. (Some other Free Software Foundation software is covered by
23 the GNU Lesser General Public License instead.) You can apply it to
26 When we speak of free software, we are referring to freedom, not
27 price. Our General Public Licenses are designed to make sure that you
28 have the freedom to distribute copies of free software (and charge for
29 this service if you wish), that you receive source code or can get it
30 if you want it, that you can change the software or use pieces of it
31 in new free programs; and that you know you can do these things.
33 To protect your rights, we need to make restrictions that forbid
34 anyone to deny you these rights or to ask you to surrender the rights.
35 These restrictions translate to certain responsibilities for you if you
36 distribute copies of the software, or if you modify it.
38 For example, if you distribute copies of such a program, whether
39 gratis or for a fee, you must give the recipients all the rights that
40 you have. You must make sure that they, too, receive or can get the
41 source code. And you must show them these terms so they know their
44 We protect your rights with two steps: (1) copyright the software, and
45 (2) offer you this license which gives you legal permission to copy,
46 distribute and/or modify the software.
48 Also, for each author's protection and ours, we want to make certain
49 that everyone understands that there is no warranty for this free
50 software. If the software is modified by someone else and passed on, we
51 want its recipients to know that what they have is not the original, so
52 that any problems introduced by others will not reflect on the original
55 Finally, any free program is threatened constantly by software
56 patents. We wish to avoid the danger that redistributors of a free
57 program will individually obtain patent licenses, in effect making the
58 program proprietary. To prevent this, we have made it clear that any
59 patent must be licensed for everyone's free use or not licensed at all.
61 The precise terms and conditions for copying, distribution and
64 GNU GENERAL PUBLIC LICENSE
65 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
67 0. This License applies to any program or other work which contains
68 a notice placed by the copyright holder saying it may be distributed
69 under the terms of this General Public License. The "Program", below,
70 refers to any such program or work, and a "work based on the Program"
71 means either the Program or any derivative work under copyright law:
72 that is to say, a work containing the Program or a portion of it,
73 either verbatim or with modifications and/or translated into another
74 language. (Hereinafter, translation is included without limitation in
75 the term "modification".) Each licensee is addressed as "you".
77 Activities other than copying, distribution and modification are not
78 covered by this License; they are outside its scope. The act of
79 running the Program is not restricted, and the output from the Program
80 is covered only if its contents constitute a work based on the
81 Program (independent of having been made by running the Program).
82 Whether that is true depends on what the Program does.
84 1. You may copy and distribute verbatim copies of the Program's
85 source code as you receive it, in any medium, provided that you
86 conspicuously and appropriately publish on each copy an appropriate
87 copyright notice and disclaimer of warranty; keep intact all the
88 notices that refer to this License and to the absence of any warranty;
89 and give any other recipients of the Program a copy of this License
90 along with the Program.
92 You may charge a fee for the physical act of transferring a copy, and
93 you may at your option offer warranty protection in exchange for a fee.
95 2. You may modify your copy or copies of the Program or any portion
96 of it, thus forming a work based on the Program, and copy and
97 distribute such modifications or work under the terms of Section 1
98 above, provided that you also meet all of these conditions:
100 a) You must cause the modified files to carry prominent notices
101 stating that you changed the files and the date of any change.
103 b) You must cause any work that you distribute or publish, that in
104 whole or in part contains or is derived from the Program or any
105 part thereof, to be licensed as a whole at no charge to all third
106 parties under the terms of this License.
108 c) If the modified program normally reads commands interactively
109 when run, you must cause it, when started running for such
110 interactive use in the most ordinary way, to print or display an
111 announcement including an appropriate copyright notice and a
112 notice that there is no warranty (or else, saying that you provide
113 a warranty) and that users may redistribute the program under
114 these conditions, and telling the user how to view a copy of this
115 License. (Exception: if the Program itself is interactive but
116 does not normally print such an announcement, your work based on
117 the Program is not required to print an announcement.)
119 These requirements apply to the modified work as a whole. If
120 identifiable sections of that work are not derived from the Program,
121 and can be reasonably considered independent and separate works in
122 themselves, then this License, and its terms, do not apply to those
123 sections when you distribute them as separate works. But when you
124 distribute the same sections as part of a whole which is a work based
125 on the Program, the distribution of the whole must be on the terms of
126 this License, whose permissions for other licensees extend to the
127 entire whole, and thus to each and every part regardless of who wrote it.
129 Thus, it is not the intent of this section to claim rights or contest
130 your rights to work written entirely by you; rather, the intent is to
131 exercise the right to control the distribution of derivative or
132 collective works based on the Program.
134 In addition, mere aggregation of another work not based on the Program
135 with the Program (or with a work based on the Program) on a volume of
136 a storage or distribution medium does not bring the other work under
137 the scope of this License.
139 3. You may copy and distribute the Program (or a work based on it,
140 under Section 2) in object code or executable form under the terms of
141 Sections 1 and 2 above provided that you also do one of the following:
143 a) Accompany it with the complete corresponding machine-readable
144 source code, which must be distributed under the terms of Sections
145 1 and 2 above on a medium customarily used for software interchange; or,
147 b) Accompany it with a written offer, valid for at least three
148 years, to give any third party, for a charge no more than your
149 cost of physically performing source distribution, a complete
150 machine-readable copy of the corresponding source code, to be
151 distributed under the terms of Sections 1 and 2 above on a medium
152 customarily used for software interchange; or,
154 c) Accompany it with the information you received as to the offer
155 to distribute corresponding source code. (This alternative is
156 allowed only for noncommercial distribution and only if you
157 received the program in object code or executable form with such
158 an offer, in accord with Subsection b above.)
160 The source code for a work means the preferred form of the work for
161 making modifications to it. For an executable work, complete source
162 code means all the source code for all modules it contains, plus any
163 associated interface definition files, plus the scripts used to
164 control compilation and installation of the executable. However, as a
165 special exception, the source code distributed need not include
166 anything that is normally distributed (in either source or binary
167 form) with the major components (compiler, kernel, and so on) of the
168 operating system on which the executable runs, unless that component
169 itself accompanies the executable.
171 If distribution of executable or object code is made by offering
172 access to copy from a designated place, then offering equivalent
173 access to copy the source code from the same place counts as
174 distribution of the source code, even though third parties are not
175 compelled to copy the source along with the object code.
177 4. You may not copy, modify, sublicense, or distribute the Program
178 except as expressly provided under this License. Any attempt
179 otherwise to copy, modify, sublicense or distribute the Program is
180 void, and will automatically terminate your rights under this License.
181 However, parties who have received copies, or rights, from you under
182 this License will not have their licenses terminated so long as such
183 parties remain in full compliance.
185 5. You are not required to accept this License, since you have not
186 signed it. However, nothing else grants you permission to modify or
187 distribute the Program or its derivative works. These actions are
188 prohibited by law if you do not accept this License. Therefore, by
189 modifying or distributing the Program (or any work based on the
190 Program), you indicate your acceptance of this License to do so, and
191 all its terms and conditions for copying, distributing or modifying
192 the Program or works based on it.
194 6. Each time you redistribute the Program (or any work based on the
195 Program), the recipient automatically receives a license from the
196 original licensor to copy, distribute or modify the Program subject to
197 these terms and conditions. You may not impose any further
198 restrictions on the recipients' exercise of the rights granted herein.
199 You are not responsible for enforcing compliance by third parties to
202 7. If, as a consequence of a court judgment or allegation of patent
203 infringement or for any other reason (not limited to patent issues),
204 conditions are imposed on you (whether by court order, agreement or
205 otherwise) that contradict the conditions of this License, they do not
206 excuse you from the conditions of this License. If you cannot
207 distribute so as to satisfy simultaneously your obligations under this
208 License and any other pertinent obligations, then as a consequence you
209 may not distribute the Program at all. For example, if a patent
210 license would not permit royalty-free redistribution of the Program by
211 all those who receive copies directly or indirectly through you, then
212 the only way you could satisfy both it and this License would be to
213 refrain entirely from distribution of the Program.
215 If any portion of this section is held invalid or unenforceable under
216 any particular circumstance, the balance of the section is intended to
217 apply and the section as a whole is intended to apply in other
220 It is not the purpose of this section to induce you to infringe any
221 patents or other property right claims or to contest validity of any
222 such claims; this section has the sole purpose of protecting the
223 integrity of the free software distribution system, which is
224 implemented by public license practices. Many people have made
225 generous contributions to the wide range of software distributed
226 through that system in reliance on consistent application of that
227 system; it is up to the author/donor to decide if he or she is willing
228 to distribute software through any other system and a licensee cannot
231 This section is intended to make thoroughly clear what is believed to
232 be a consequence of the rest of this License.
234 8. If the distribution and/or use of the Program is restricted in
235 certain countries either by patents or by copyrighted interfaces, the
236 original copyright holder who places the Program under this License
237 may add an explicit geographical distribution limitation excluding
238 those countries, so that distribution is permitted only in or among
239 countries not thus excluded. In such case, this License incorporates
240 the limitation as if written in the body of this License.
242 9. The Free Software Foundation may publish revised and/or new versions
243 of the General Public License from time to time. Such new versions will
244 be similar in spirit to the present version, but may differ in detail to
245 address new problems or concerns.
247 Each version is given a distinguishing version number. If the Program
248 specifies a version number of this License which applies to it and "any
249 later version", you have the option of following the terms and conditions
250 either of that version or of any later version published by the Free
251 Software Foundation. If the Program does not specify a version number of
252 this License, you may choose any version ever published by the Free Software
255 10. If you wish to incorporate parts of the Program into other free
256 programs whose distribution conditions are different, write to the author
257 to ask for permission. For software which is copyrighted by the Free
258 Software Foundation, write to the Free Software Foundation; we sometimes
259 make exceptions for this. Our decision will be guided by the two goals
260 of preserving the free status of all derivatives of our free software and
261 of promoting the sharing and reuse of software generally.
265 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
266 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
267 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
268 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
269 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
270 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
271 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
272 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
273 REPAIR OR CORRECTION.
275 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
276 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
277 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
278 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
279 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
280 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
281 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
282 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
283 POSSIBILITY OF SUCH DAMAGES.
285 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 along
312 with this program; if not, write to the Free Software Foundation, Inc.,
313 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
315 Also add information on how to contact you by electronic and paper mail.
317 If the program is interactive, make it output a short notice like this
318 when it starts in an interactive mode:
320 Gnomovision version 69, Copyright (C) year name of author
321 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
322 This is free software, and you are welcome to redistribute it
323 under certain conditions; type `show c' for details.
325 The hypothetical commands `show w' and `show c' should show the appropriate
326 parts of the General Public License. Of course, the commands you use may
327 be called something other than `show w' and `show c'; they could even be
328 mouse-clicks or menu items--whatever suits your program.
330 You should also get your employer (if you work as a programmer) or your
331 school, if any, to sign a "copyright disclaimer" for the program, if
332 necessary. Here is a sample; alter the names:
334 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
335 `Gnomovision' (which makes passes at compilers) written by James Hacker.

338 Ty Coon, President of Vice
340 This General Public License does not permit incorporating your program into
341 proprietary programs. If your program is a subroutine library, you may
342 consider it more useful to permit linking proprietary applications with the
343 library. If this is what you want to do, use the GNU Lesser General
344 Public License instead of this License.

347 GNU LESSER GENERAL PUBLIC LICENSE
348 Version 2.1, February 1999
350 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
351 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
352 Everyone is permitted to copy and distribute verbatim copies
353 of this license document, but changing it is not allowed.
355 [This is the first released version of the Lesser GPL. It also counts
356 as the successor of the GNU Library Public License, version 2, hence
357 the version number 2.1.]
361 The licenses for most software are designed to take away your
362 freedom to share and change it. By contrast, the GNU General Public
363 Licenses are intended to guarantee your freedom to share and change
364 free software--to make sure the software is free for all its users.
366 This license, the Lesser General Public License, applies to some
367 specially designated software packages--typically libraries--of the
368 Free Software Foundation and other authors who decide to use it. You
369 can use it too, but we suggest you first think carefully about whether
370 this license or the ordinary General Public License is the better
371 strategy to use in any particular case, based on the explanations below.
373 When we speak of free software, we are referring to freedom of use,
374 not price. Our General Public Licenses are designed to make sure that
375 you have the freedom to distribute copies of free software (and charge
376 for this service if you wish); that you receive source code or can get
377 it if you want it; that you can change the software and use pieces of
378 it in new free programs; and that you are informed that you can do
381 To protect your rights, we need to make restrictions that forbid
382 distributors to deny you these rights or to ask you to surrender these
383 rights. These restrictions translate to certain responsibilities for
384 you if you distribute copies of the library or if you modify it.
386 For example, if you distribute copies of the library, whether gratis
387 or for a fee, you must give the recipients all the rights that we gave
388 you. You must make sure that they, too, receive or can get the source
389 code. If you link other code with the library, you must provide
390 complete object files to the recipients, so that they can relink them
391 with the library after making changes to the library and recompiling
392 it. And you must show them these terms so they know their rights.
394 We protect your rights with a two-step method: (1) we copyright the
395 library, and (2) we offer you this license, which gives you legal
396 permission to copy, distribute and/or modify the library.
398 To protect each distributor, we want to make it very clear that
399 there is no warranty for the free library. Also, if the library is
400 modified by someone else and passed on, the recipients should know
401 that what they have is not the original version, so that the original
402 author's reputation will not be affected by problems that might be
403 introduced by others.
405 Finally, software patents pose a constant threat to the existence of
406 any free program. We wish to make sure that a company cannot
407 effectively restrict the users of a free program by obtaining a
408 restrictive license from a patent holder. Therefore, we insist that
409 any patent license obtained for a version of the library must be
410 consistent with the full freedom of use specified in this license.
412 Most GNU software, including some libraries, is covered by the
413 ordinary GNU General Public License. This license, the GNU Lesser
414 General Public License, applies to certain designated libraries, and
415 is quite different from the ordinary General Public License. We use
416 this license for certain libraries in order to permit linking those
417 libraries into non-free programs.
419 When a program is linked with a library, whether statically or using
420 a shared library, the combination of the two is legally speaking a
421 combined work, a derivative of the original library. The ordinary
422 General Public License therefore permits such linking only if the
423 entire combination fits its criteria of freedom. The Lesser General
424 Public License permits more lax criteria for linking other code with
427 We call this license the "Lesser" General Public License because it
428 does Less to protect the user's freedom than the ordinary General
429 Public License. It also provides other free software developers Less
430 of an advantage over competing non-free programs. These disadvantages
431 are the reason we use the ordinary General Public License for many
432 libraries. However, the Lesser license provides advantages in certain
433 special circumstances.
435 For example, on rare occasions, there may be a special need to
436 encourage the widest possible use of a certain library, so that it becomes
437 a de-facto standard. To achieve this, non-free programs must be
438 allowed to use the library. A more frequent case is that a free
439 library does the same job as widely used non-free libraries. In this
440 case, there is little to gain by limiting the free library to free
441 software only, so we use the Lesser General Public License.
443 In other cases, permission to use a particular library in non-free
444 programs enables a greater number of people to use a large body of
445 free software. For example, permission to use the GNU C Library in
446 non-free programs enables many more people to use the whole GNU
447 operating system, as well as its variant, the GNU/Linux operating
450 Although the Lesser General Public License is Less protective of the
451 users' freedom, it does ensure that the user of a program that is
452 linked with the Library has the freedom and the wherewithal to run
453 that program using a modified version of the Library.
455 The precise terms and conditions for copying, distribution and
456 modification follow. Pay close attention to the difference between a
457 "work based on the library" and a "work that uses the library". The
458 former contains code derived from the library, whereas the latter must
459 be combined with the library in order to run.
461 GNU LESSER GENERAL PUBLIC LICENSE
462 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
464 0. This License Agreement applies to any software library or other
465 program which contains a notice placed by the copyright holder or
466 other authorized party saying it may be distributed under the terms of
467 this Lesser General Public License (also called "this License").
468 Each licensee is addressed as "you".
470 A "library" means a collection of software functions and/or data
471 prepared so as to be conveniently linked with application programs
472 (which use some of those functions and data) to form executables.
474 The "Library", below, refers to any such software library or work
475 which has been distributed under these terms. A "work based on the
476 Library" means either the Library or any derivative work under
477 copyright law: that is to say, a work containing the Library or a
478 portion of it, either verbatim or with modifications and/or translated
479 straightforwardly into another language. (Hereinafter, translation is
480 included without limitation in the term "modification".)
482 "Source code" for a work means the preferred form of the work for
483 making modifications to it. For a library, complete source code means
484 all the source code for all modules it contains, plus any associated
485 interface definition files, plus the scripts used to control compilation
486 and installation of the library.
488 Activities other than copying, distribution and modification are not
489 covered by this License; they are outside its scope. The act of
490 running a program using the Library is not restricted, and output from
491 such a program is covered only if its contents constitute a work based
492 on the Library (independent of the use of the Library in a tool for
493 writing it). Whether that is true depends on what the Library does
494 and what the program that uses the Library does.
496 1. You may copy and distribute verbatim copies of the Library's
497 complete source code as you receive it, in any medium, provided that
498 you conspicuously and appropriately publish on each copy an
499 appropriate copyright notice and disclaimer of warranty; keep intact
500 all the notices that refer to this License and to the absence of any
501 warranty; and distribute a copy of this License along with the
504 You may charge a fee for the physical act of transferring a copy,
505 and you may at your option offer warranty protection in exchange for a
508 2. You may modify your copy or copies of the Library or any portion
509 of it, thus forming a work based on the Library, and copy and
510 distribute such modifications or work under the terms of Section 1
511 above, provided that you also meet all of these conditions:
513 a) The modified work must itself be a software library.
515 b) You must cause the files modified to carry prominent notices
516 stating that you changed the files and the date of any change.
518 c) You must cause the whole of the work to be licensed at no
519 charge to all third parties under the terms of this License.
521 d) If a facility in the modified Library refers to a function or a
522 table of data to be supplied by an application program that uses
523 the facility, other than as an argument passed when the facility
524 is invoked, then you must make a good faith effort to ensure that,
525 in the event an application does not supply such function or
526 table, the facility still operates, and performs whatever part of
527 its purpose remains meaningful.
529 (For example, a function in a library to compute square roots has
530 a purpose that is entirely well-defined independent of the
531 application. Therefore, Subsection 2d requires that any
532 application-supplied function or table used by this function must
533 be optional: if the application does not supply it, the square
534 root function must still compute square roots.)
536 These requirements apply to the modified work as a whole. If
537 identifiable sections of that work are not derived from the Library,
538 and can be reasonably considered independent and separate works in
539 themselves, then this License, and its terms, do not apply to those
540 sections when you distribute them as separate works. But when you
541 distribute the same sections as part of a whole which is a work based
542 on the Library, the distribution of the whole must be on the terms of
543 this License, whose permissions for other licensees extend to the
544 entire whole, and thus to each and every part regardless of who wrote
547 Thus, it is not the intent of this section to claim rights or contest
548 your rights to work written entirely by you; rather, the intent is to
549 exercise the right to control the distribution of derivative or
550 collective works based on the Library.
552 In addition, mere aggregation of another work not based on the Library
553 with the Library (or with a work based on the Library) on a volume of
554 a storage or distribution medium does not bring the other work under
555 the scope of this License.
557 3. You may opt to apply the terms of the ordinary GNU General Public
558 License instead of this License to a given copy of the Library. To do
559 this, you must alter all the notices that refer to this License, so
560 that they refer to the ordinary GNU General Public License, version 2,
561 instead of to this License. (If a newer version than version 2 of the
562 ordinary GNU General Public License has appeared, then you can specify
563 that version instead if you wish.) Do not make any other change in
566 Once this change is made in a given copy, it is irreversible for
567 that copy, so the ordinary GNU General Public License applies to all
568 subsequent copies and derivative works made from that copy.
570 This option is useful when you wish to copy part of the code of
571 the Library into a program that is not a library.
573 4. You may copy and distribute the Library (or a portion or
574 derivative of it, under Section 2) in object code or executable form
575 under the terms of Sections 1 and 2 above provided that you accompany
576 it with the complete corresponding machine-readable source code, which
577 must be distributed under the terms of Sections 1 and 2 above on a
578 medium customarily used for software interchange.
580 If distribution of object code is made by offering access to copy
581 from a designated place, then offering equivalent access to copy the
582 source code from the same place satisfies the requirement to
583 distribute the source code, even though third parties are not
584 compelled to copy the source along with the object code.
586 5. A program that contains no derivative of any portion of the
587 Library, but is designed to work with the Library by being compiled or
588 linked with it, is called a "work that uses the Library". Such a
589 work, in isolation, is not a derivative work of the Library, and
590 therefore falls outside the scope of this License.
592 However, linking a "work that uses the Library" with the Library
593 creates an executable that is a derivative of the Library (because it
594 contains portions of the Library), rather than a "work that uses the
595 library". The executable is therefore covered by this License.
596 Section 6 states terms for distribution of such executables.
598 When a "work that uses the Library" uses material from a header file
599 that is part of the Library, the object code for the work may be a
600 derivative work of the Library even though the source code is not.
601 Whether this is true is especially significant if the work can be
602 linked without the Library, or if the work is itself a library. The
603 threshold for this to be true is not precisely defined by law.
605 If such an object file uses only numerical parameters, data
606 structure layouts and accessors, and small macros and small inline
607 functions (ten lines or less in length), then the use of the object
608 file is unrestricted, regardless of whether it is legally a derivative
609 work. (Executables containing this object code plus portions of the
610 Library will still fall under Section 6.)
612 Otherwise, if the work is a derivative of the Library, you may
613 distribute the object code for the work under the terms of Section 6.
614 Any executables containing that work also fall under Section 6,
615 whether or not they are linked directly with the Library itself.
617 6. As an exception to the Sections above, you may also combine or
618 link a "work that uses the Library" with the Library to produce a
619 work containing portions of the Library, and distribute that work
620 under terms of your choice, provided that the terms permit
621 modification of the work for the customer's own use and reverse
622 engineering for debugging such modifications.
624 You must give prominent notice with each copy of the work that the
625 Library is used in it and that the Library and its use are covered by
626 this License. You must supply a copy of this License. If the work
627 during execution displays copyright notices, you must include the
628 copyright notice for the Library among them, as well as a reference
629 directing the user to the copy of this License. Also, you must do one
632 a) Accompany the work with the complete corresponding
633 machine-readable source code for the Library including whatever
634 changes were used in the work (which must be distributed under
635 Sections 1 and 2 above); and, if the work is an executable linked
636 with the Library, with the complete machine-readable "work that
637 uses the Library", as object code and/or source code, so that the
638 user can modify the Library and then relink to produce a modified
639 executable containing the modified Library. (It is understood
640 that the user who changes the contents of definitions files in the
641 Library will not necessarily be able to recompile the application
642 to use the modified definitions.)
644 b) Use a suitable shared library mechanism for linking with the
645 Library. A suitable mechanism is one that (1) uses at run time a
646 copy of the library already present on the user's computer system,
647 rather than copying library functions into the executable, and (2)
648 will operate properly with a modified version of the library, if
649 the user installs one, as long as the modified version is
650 interface-compatible with the version that the work was made with.
652 c) Accompany the work with a written offer, valid for at
653 least three years, to give the same user the materials
654 specified in Subsection 6a, above, for a charge no more
655 than the cost of performing this distribution.
657 d) If distribution of the work is made by offering access to copy
658 from a designated place, offer equivalent access to copy the above
659 specified materials from the same place.
661 e) Verify that the user has already received a copy of these
662 materials or that you have already sent this user a copy.
664 For an executable, the required form of the "work that uses the
665 Library" must include any data and utility programs needed for
666 reproducing the executable from it. However, as a special exception,
667 the materials to be distributed need not include anything that is
668 normally distributed (in either source or binary form) with the major
669 components (compiler, kernel, and so on) of the operating system on
670 which the executable runs, unless that component itself accompanies
673 It may happen that this requirement contradicts the license
674 restrictions of other proprietary libraries that do not normally
675 accompany the operating system. Such a contradiction means you cannot
676 use both them and the Library together in an executable that you
679 7. You may place library facilities that are a work based on the
680 Library side-by-side in a single library together with other library
681 facilities not covered by this License, and distribute such a combined
682 library, provided that the separate distribution of the work based on
683 the Library and of the other library facilities is otherwise
684 permitted, and provided that you do these two things:
686 a) Accompany the combined library with a copy of the same work
687 based on the Library, uncombined with any other library
688 facilities. This must be distributed under the terms of the
691 b) Give prominent notice with the combined library of the fact
692 that part of it is a work based on the Library, and explaining
693 where to find the accompanying uncombined form of the same work.
695 8. You may not copy, modify, sublicense, link with, or distribute
696 the Library except as expressly provided under this License. Any
697 attempt otherwise to copy, modify, sublicense, link with, or
698 distribute the Library is void, and will automatically terminate your
699 rights under this License. However, parties who have received copies,
700 or rights, from you under this License will not have their licenses
701 terminated so long as such parties remain in full compliance.
703 9. You are not required to accept this License, since you have not
704 signed it. However, nothing else grants you permission to modify or
705 distribute the Library or its derivative works. These actions are
706 prohibited by law if you do not accept this License. Therefore, by
707 modifying or distributing the Library (or any work based on the
708 Library), you indicate your acceptance of this License to do so, and
709 all its terms and conditions for copying, distributing or modifying
710 the Library or works based on it.
712 10. Each time you redistribute the Library (or any work based on the
713 Library), the recipient automatically receives a license from the
714 original licensor to copy, distribute, link with or modify the Library
715 subject to these terms and conditions. You may not impose any further
716 restrictions on the recipients' exercise of the rights granted herein.
717 You are not responsible for enforcing compliance by third parties with
720 11. If, as a consequence of a court judgment or allegation of patent
721 infringement or for any other reason (not limited to patent issues),
722 conditions are imposed on you (whether by court order, agreement or
723 otherwise) that contradict the conditions of this License, they do not
724 excuse you from the conditions of this License. If you cannot
725 distribute so as to satisfy simultaneously your obligations under this
726 License and any other pertinent obligations, then as a consequence you
727 may not distribute the Library at all. For example, if a patent
728 license would not permit royalty-free redistribution of the Library by
729 all those who receive copies directly or indirectly through you, then
730 the only way you could satisfy both it and this License would be to
731 refrain entirely from distribution of the Library.
733 If any portion of this section is held invalid or unenforceable under any
734 particular circumstance, the balance of the section is intended to apply,
735 and the section as a whole is intended to apply in other circumstances.
737 It is not the purpose of this section to induce you to infringe any
738 patents or other property right claims or to contest validity of any
739 such claims; this section has the sole purpose of protecting the
740 integrity of the free software distribution system which is
741 implemented by public license practices. Many people have made
742 generous contributions to the wide range of software distributed
743 through that system in reliance on consistent application of that
744 system; it is up to the author/donor to decide if he or she is willing
745 to distribute software through any other system and a licensee cannot
748 This section is intended to make thoroughly clear what is believed to
749 be a consequence of the rest of this License.
751 12. If the distribution and/or use of the Library is restricted in
752 certain countries either by patents or by copyrighted interfaces, the
753 original copyright holder who places the Library under this License may add
754 an explicit geographical distribution limitation excluding those countries,
755 so that distribution is permitted only in or among countries not thus
756 excluded. In such case, this License incorporates the limitation as if
757 written in the body of this License.
759 13. The Free Software Foundation may publish revised and/or new
760 versions of the Lesser General Public License from time to time.
761 Such new versions will be similar in spirit to the present version,
762 but may differ in detail to address new problems or concerns.
764 Each version is given a distinguishing version number. If the Library
765 specifies a version number of this License which applies to it and
766 "any later version", you have the option of following the terms and
767 conditions either of that version or of any later version published by
768 the Free Software Foundation. If the Library does not specify a
769 license version number, you may choose any version ever published by
770 the Free Software Foundation.
772 14. If you wish to incorporate parts of the Library into other free
773 programs whose distribution conditions are incompatible with these,
774 write to the author to ask for permission. For software which is
775 copyrighted by the Free Software Foundation, write to the Free
776 Software Foundation; we sometimes make exceptions for this. Our
777 decision will be guided by the two goals of preserving the free status
778 of all derivatives of our free software and of promoting the sharing
779 and reuse of software generally.
783 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
784 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
785 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
786 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
787 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
788 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
789 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
790 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
791 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
793 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
794 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
795 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
796 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
797 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
798 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
799 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
800 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
801 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
804 END OF TERMS AND CONDITIONS
806 How to Apply These Terms to Your New Libraries
808 If you develop a new library, and you want it to be of the greatest
809 possible use to the public, we recommend making it free software that
810 everyone can redistribute and change. You can do so by permitting
811 redistribution under these terms (or, alternatively, under the terms of the
812 ordinary General Public License).
814 To apply these terms, attach the following notices to the library. It is
815 safest to attach them to the start of each source file to most effectively
816 convey the exclusion of warranty; and each file should have at least the
817 "copyright" line and a pointer to where the full notice is found.
819 <one line to give the library's name and a brief idea of what it does.>
820 Copyright (C) <year> <name of author>
822 This library is free software; you can redistribute it and/or
823 modify it under the terms of the GNU Lesser General Public
824 License as published by the Free Software Foundation; either
825 version 2.1 of the License, or (at your option) any later version.
827 This library is distributed in the hope that it will be useful,
828 but WITHOUT ANY WARRANTY; without even the implied warranty of
829 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
830 Lesser General Public License for more details.
832 You should have received a copy of the GNU Lesser General Public
833 License along with this library; if not, write to the Free Software
834 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
836 Also add information on how to contact you by electronic and paper mail.
838 You should also get your employer (if you work as a programmer) or your
839 school, if any, to sign a "copyright disclaimer" for the library, if
840 necessary. Here is a sample; alter the names:

854 Everyone is permitted to copy and distribute verbatim copies
855 of this license document, but changing it is not allowed.
860 The purpose of this License is to make a manual, textbook, or other
861 written document "free" in the sense of freedom: to assure everyone
862 the effective freedom to copy and redistribute it, with or without
863 modifying it, either commercially or noncommercially. Secondarily,
864 this License preserves for the author and publisher a way to get
865 credit for their work, while not being considered responsible for
866 modifications made by others.
868 This License is a kind of "copyleft", which means that derivative
869 works of the document must themselves be free in the same sense. It
870 complements the GNU General Public License, which is a copyleft
871 license designed for free software.
873 We have designed this License in order to use it for manuals for free
874 software, because free software needs free documentation: a free
875 program should come with manuals providing the same freedoms that the
876 software does. But this License is not limited to software manuals;
877 it can be used for any textual work, regardless of subject matter or
878 whether it is published as a printed book. We recommend this License
879 principally for works whose purpose is instruction or reference.
882 1. APPLICABILITY AND DEFINITIONS
884 This License applies to any manual or other work that contains a
885 notice placed by the copyright holder saying it can be distributed
886 under the terms of this License. The "Document", below, refers to any
887 such manual or work. Any member of the public is a licensee, and is
890 A "Modified Version" of the Document means any work containing the
891 Document or a portion of it, either copied verbatim, or with
892 modifications and/or translated into another language.
894 A "Secondary Section" is a named appendix or a front-matter section of
895 the Document that deals exclusively with the relationship of the
896 publishers or authors of the Document to the Document's overall subject
897 (or to related matters) and contains nothing that could fall directly
898 within that overall subject. (For example, if the Document is in part a
899 textbook of mathematics, a Secondary Section may not explain any
900 mathematics.) The relationship could be a matter of historical
901 connection with the subject or with related matters, or of legal,
902 commercial, philosophical, ethical or political position regarding
905 The "Invariant Sections" are certain Secondary Sections whose titles
906 are designated, as being those of Invariant Sections, in the notice
907 that says that the Document is released under this License.
909 The "Cover Texts" are certain short passages of text that are listed,
910 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
911 the Document is released under this License.
913 A "Transparent" copy of the Document means a machine-readable copy,
914 represented in a format whose specification is available to the
915 general public, whose contents can be viewed and edited directly and
916 straightforwardly with generic text editors or (for images composed of
917 pixels) generic paint programs or (for drawings) some widely available
918 drawing editor, and that is suitable for input to text formatters or
919 for automatic translation to a variety of formats suitable for input
920 to text formatters. A copy made in an otherwise Transparent file
921 format whose markup has been designed to thwart or discourage
922 subsequent modification by readers is not Transparent. A copy that is
923 not "Transparent" is called "Opaque".
925 Examples of suitable formats for Transparent copies include plain
926 ASCII without markup, Texinfo input format, LaTeX input format, SGML
927 or XML using a publicly available DTD, and standard-conforming simple
928 HTML designed for human modification. Opaque formats include
929 PostScript, PDF, proprietary formats that can be read and edited only
930 by proprietary word processors, SGML or XML for which the DTD and/or
931 processing tools are not generally available, and the
932 machine-generated HTML produced by some word processors for output
935 The "Title Page" means, for a printed book, the title page itself,
936 plus such following pages as are needed to hold, legibly, the material
937 this License requires to appear in the title page. For works in
938 formats which do not have any title page as such, "Title Page" means
939 the text near the most prominent appearance of the work's title,
940 preceding the beginning of the body of the text.
945 You may copy and distribute the Document in any medium, either
946 commercially or noncommercially, provided that this License, the
947 copyright notices, and the license notice saying this License applies
948 to the Document are reproduced in all copies, and that you add no other
949 conditions whatsoever to those of this License. You may not use
950 technical measures to obstruct or control the reading or further
951 copying of the copies you make or distribute. However, you may accept
952 compensation in exchange for copies. If you distribute a large enough
953 number of copies you must also follow the conditions in section 3.
955 You may also lend copies, under the same conditions stated above, and
956 you may publicly display copies.
959 3. COPYING IN QUANTITY
961 If you publish printed copies of the Document numbering more than 100,
962 and the Document's license notice requires Cover Texts, you must enclose
963 the copies in covers that carry, clearly and legibly, all these Cover
964 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
965 the back cover. Both covers must also clearly and legibly identify
966 you as the publisher of these copies. The front cover must present
967 the full title with all words of the title equally prominent and
968 visible. You may add other material on the covers in addition.
969 Copying with changes limited to the covers, as long as they preserve
970 the title of the Document and satisfy these conditions, can be treated
971 as verbatim copying in other respects.
973 If the required texts for either cover are too voluminous to fit
974 legibly, you should put the first ones listed (as many as fit
975 reasonably) on the actual cover, and continue the rest onto adjacent
978 If you publish or distribute Opaque copies of the Document numbering
979 more than 100, you must either include a machine-readable Transparent
980 copy along with each Opaque copy, or state in or with each Opaque copy
981 a publicly-accessible computer-network location containing a complete
982 Transparent copy of the Document, free of added material, which the
983 general network-using public has access to download anonymously at no
984 charge using public-standard network protocols. If you use the latter
985 option, you must take reasonably prudent steps, when you begin
986 distribution of Opaque copies in quantity, to ensure that this
987 Transparent copy will remain thus accessible at the stated location
988 until at least one year after the last time you distribute an Opaque
989 copy (directly or through your agents or retailers) of that edition to
992 It is requested, but not required, that you contact the authors of the
993 Document well before redistributing any large number of copies, to give
994 them a chance to provide you with an updated version of the Document.
999 You may copy and distribute a Modified Version of the Document under
1000 the conditions of sections 2 and 3 above, provided that you release
1001 the Modified Version under precisely this License, with the Modified
1002 Version filling the role of the Document, thus licensing distribution
1003 and modification of the Modified Version to whoever possesses a copy
1004 of it. In addition, you must do these things in the Modified Version:
1006 A. Use in the Title Page (and on the covers, if any) a title distinct
1007 from that of the Document, and from those of previous versions
1008 (which should, if there were any, be listed in the History section
1009 of the Document). You may use the same title as a previous version
1010 if the original publisher of that version gives permission.
1011 B. List on the Title Page, as authors, one or more persons or entities
1012 responsible for authorship of the modifications in the Modified
1013 Version, together with at least five of the principal authors of the
1014 Document (all of its principal authors, if it has less than five).
1015 C. State on the Title page the name of the publisher of the
1016 Modified Version, as the publisher.
1017 D. Preserve all the copyright notices of the Document.
1018 E. Add an appropriate copyright notice for your modifications
1019 adjacent to the other copyright notices.
1020 F. Include, immediately after the copyright notices, a license notice
1021 giving the public permission to use the Modified Version under the
1022 terms of this License, in the form shown in the Addendum below.
1023 G. Preserve in that license notice the full lists of Invariant Sections
1024 and required Cover Texts given in the Document's license notice.
1025 H. Include an unaltered copy of this License.
1026 I. Preserve the section entitled "History", and its title, and add to
1027 it an item stating at least the title, year, new authors, and
1028 publisher of the Modified Version as given on the Title Page. If
1029 there is no section entitled "History" in the Document, create one
1030 stating the title, year, authors, and publisher of the Document as
1031 given on its Title Page, then add an item describing the Modified
1032 Version as stated in the previous sentence.
1033 J. Preserve the network location, if any, given in the Document for
1034 public access to a Transparent copy of the Document, and likewise
1035 the network locations given in the Document for previous versions
1036 it was based on. These may be placed in the "History" section.
1037 You may omit a network location for a work that was published at
1038 least four years before the Document itself, or if the original
1039 publisher of the version it refers to gives permission.
1040 K. In any section entitled "Acknowledgements" or "Dedications",
1041 preserve the section's title, and preserve in the section all the
1042 substance and tone of each of the contributor acknowledgements
1043 and/or dedications given therein.
1044 L. Preserve all the Invariant Sections of the Document,
1045 unaltered in their text and in their titles. Section numbers
1046 or the equivalent are not considered part of the section titles.
1047 M. Delete any section entitled "Endorsements". Such a section
1048 may not be included in the Modified Version.
1049 N. Do not retitle any existing section as "Endorsements"
1050 or to conflict in title with any Invariant Section.
1052 If the Modified Version includes new front-matter sections or
1053 appendices that qualify as Secondary Sections and contain no material
1054 copied from the Document, you may at your option designate some or all
1055 of these sections as invariant. To do this, add their titles to the
1056 list of Invariant Sections in the Modified Version's license notice.
1057 These titles must be distinct from any other section titles.
1059 You may add a section entitled "Endorsements", provided it contains
1060 nothing but endorsements of your Modified Version by various
1061 parties--for example, statements of peer review or that the text has
1062 been approved by an organization as the authoritative definition of a
1065 You may add a passage of up to five words as a Front-Cover Text, and a
1066 passage of up to 25 words as a Back-Cover Text, to the end of the list
1067 of Cover Texts in the Modified Version. Only one passage of
1068 Front-Cover Text and one of Back-Cover Text may be added by (or
1069 through arrangements made by) any one entity. If the Document already
1070 includes a cover text for the same cover, previously added by you or
1071 by arrangement made by the same entity you are acting on behalf of,
1072 you may not add another; but you may replace the old one, on explicit
1073 permission from the previous publisher that added the old one.
1075 The author(s) and publisher(s) of the Document do not by this License
1076 give permission to use their names for publicity for or to assert or
1077 imply endorsement of any Modified Version.
1080 5. COMBINING DOCUMENTS
1082 You may combine the Document with other documents released under this
1083 License, under the terms defined in section 4 above for modified
1084 versions, provided that you include in the combination all of the
1085 Invariant Sections of all of the original documents, unmodified, and
1086 list them all as Invariant Sections of your combined work in its
1089 The combined work need only contain one copy of this License, and
1090 multiple identical Invariant Sections may be replaced with a single
1091 copy. If there are multiple Invariant Sections with the same name but
1092 different contents, make the title of each such section unique by
1093 adding at the end of it, in parentheses, the name of the original
1094 author or publisher of that section if known, or else a unique number.
1095 Make the same adjustment to the section titles in the list of
1096 Invariant Sections in the license notice of the combined work.
1098 In the combination, you must combine any sections entitled "History"
1099 in the various original documents, forming one section entitled
1100 "History"; likewise combine any sections entitled "Acknowledgements",
1101 and any sections entitled "Dedications". You must delete all sections
1102 entitled "Endorsements."
1105 6. COLLECTIONS OF DOCUMENTS
1107 You may make a collection consisting of the Document and other documents
1108 released under this License, and replace the individual copies of this
1109 License in the various documents with a single copy that is included in
1110 the collection, provided that you follow the rules of this License for
1111 verbatim copying of each of the documents in all other respects.
1113 You may extract a single document from such a collection, and distribute
1114 it individually under this License, provided you insert a copy of this
1115 License into the extracted document, and follow this License in all
1116 other respects regarding verbatim copying of that document.
1119 7. AGGREGATION WITH INDEPENDENT WORKS
1121 A compilation of the Document or its derivatives with other separate
1122 and independent documents or works, in or on a volume of a storage or
1123 distribution medium, does not as a whole count as a Modified Version
1124 of the Document, provided no compilation copyright is claimed for the
1125 compilation. Such a compilation is called an "aggregate", and this
1126 License does not apply to the other self-contained works thus compiled
1127 with the Document, on account of their being thus compiled, if they
1128 are not themselves derivative works of the Document.
1130 If the Cover Text requirement of section 3 is applicable to these
1131 copies of the Document, then if the Document is less than one quarter
1132 of the entire aggregate, the Document's Cover Texts may be placed on
1133 covers that surround only the Document within the aggregate.
1134 Otherwise they must appear on covers around the whole aggregate.
1139 Translation is considered a kind of modification, so you may
1140 distribute translations of the Document under the terms of section 4.
1141 Replacing Invariant Sections with translations requires special
1142 permission from their copyright holders, but you may include
1143 translations of some or all Invariant Sections in addition to the
1144 original versions of these Invariant Sections. You may include a
1145 translation of this License provided that you also include the
1146 original English version of this License. In case of a disagreement
1147 between the translation and the original English version of this
1148 License, the original English version will prevail.
1153 You may not copy, modify, sublicense, or distribute the Document except
1154 as expressly provided for under this License. Any other attempt to
1155 copy, modify, sublicense or distribute the Document is void, and will
1156 automatically terminate your rights under this License. However,
1157 parties who have received copies, or rights, from you under this
1158 License will not have their licenses terminated so long as such
1159 parties remain in full compliance.
1162 10. FUTURE REVISIONS OF THIS LICENSE
1164 The Free Software Foundation may publish new, revised versions
1165 of the GNU Free Documentation License from time to time. Such new
1166 versions will be similar in spirit to the present version, but may
1167 differ in detail to address new problems or concerns. See
1168 http://www.gnu.org/copyleft/.
1170 Each version of the License is given a distinguishing version number.
1171 If the Document specifies that a particular numbered version of this
1172 License "or any later version" applies to it, you have the option of
1173 following the terms and conditions either of that specified version or
1174 of any later version that has been published (not as a draft) by the
1175 Free Software Foundation. If the Document does not specify a version
1176 number of this License, you may choose any version ever published (not
1177 as a draft) by the Free Software Foundation.
1180 ADDENDUM: How to use this License for your documents
1182 To use this License in a document you have written, include a copy of
1183 the License in the document and put the following copyright and
1184 license notices just after the title page:
1186 Copyright (c) YEAR YOUR NAME.
1187 Permission is granted to copy, distribute and/or modify this document
1188 under the terms of the GNU Free Documentation License, Version 1.1
1189 or any later version published by the Free Software Foundation;
1190 with the Invariant Sections being LIST THEIR TITLES, with the
1191 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
1192 A copy of the license is included in the section entitled "GNU
1193 Free Documentation License".
1195 If you have no Invariant Sections, write "with no Invariant Sections"
1196 instead of saying which ones are invariant. If you have no
1197 Front-Cover Texts, write "no Front-Cover Texts" instead of
1198 "Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
1200 If your document contains nontrivial examples of program code, we
1201 recommend releasing these examples in parallel under your choice of
1202 free software license, such as the GNU General Public License,
1203 to permit their use in free software.
