1 The Gnome Documentation Utilities is a collection of programs and data files
2 to help you build, maintain, and distribute documentation. This package is
3 entirely free software; however, not all components of the package are under
4 the same free software license.
6 The GNU General Public License and the GNU Lesser General Public License are
7 used for particular components of this package, depending on need. You should
8 have received a copy of both licenses with this package; see COPYING.GPL and
9 COPYING.LGPL. If you did not receive these files, write to the Free Software
10 Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
12 This document attempts to provide a brief overview of the programs in this
13 package and their licensing terms.
18 The xml2po program is used to convert between PO files and XML documents.
19 Within gnome-doc-utils, it is used primarily to translate documentation
20 written in the DocBook format. It was written by Danilo Segan.
22 xml2po is released under the terms of the GNU GPL. PO and XML files
23 output by xml2po are unaffected by the GPL; you are free to license
24 them however you see fit.
29 The gnome-doc-prepare script is used to initialize your source tree for
30 using the gnome-doc-utils build utilities. It can also be used to create
31 a template document and the necessary supporting files and folders. It
32 was written by Danilo Segan.
34 gnome-doc-prepare is released under the terms of the GNU GPL. The build
35 files output by gnome-doc-prepare are unaffected by the GPL; you are free
36 to distribute them however you see fit. The template files are separate
37 entities from gnome-doc-prepare. They should specify their own terms of
38 distribution. In many cases, they will be simply stubs, and will have no
39 restrictions on modification or redistribution.
41 As a special exception to the GNU General Public License, if you distribute
42 gnome-doc-prepare as part of a program that contains a configuration script
43 generated by Autoconf, you may include gnome-doc-prepare under the same
44 distribution terms that you use for the rest of that program.
49 The gnome-doc-utils.make make script can be included into your Makefiles
50 to build, verify, and install your documentation. It was written by
53 gnome-doc-utils.make is released under the terms of the GNU GPL. Most
54 files output by gnome-doc-utils.make are actually output using one of
55 the other tools in this package, or using a commonly-available tool
56 from another package. Thus, the files output by this script are not
57 affected by the GPL. They may, however, be affected by the terms of
58 the individual programs that are being invoked.
60 We make every effort to avoid calling programs that will introduce
61 restrictions on redistribution of your package; however, we can not
62 guarantee that no such restrictions exist for files generated by tools
65 As a special exception to the GNU General Public License, if you distribute
66 gnome-doc-utils.make as part of a program that contains a configuration script
67 generated by Autoconf, you may include gnome-doc-utils.make under the same
68 distribution terms that you use for the rest of that program.
73 This package contains various XSLT files for transforming DocBook and other
74 formats. They were written primarily by Shaun McCance.
76 The XSLT files are released under the terms of the GNU LGPL. You may build
77 customizations from these stylesheets using their public documented interfaces,
78 using either xsl:import or xsl:include, with no restrictions on your customized
79 stylesheets. You may also invoke the stylesheets freely, either with a simple
80 XSLT processor such as xsltproc, or using an XSLT processing library within
81 your program. The use of these stylesheets has no bearing on the licensing
82 terms of the XSLT processing program you use.
84 The files output by the stylesheets are not affected by the terms of the LGPL.
85 In particular, some of the stylesheets output program files rather than simple
86 data files. The generated program files are also not affected by the LGPL.
87 You can redistribute all generated files as you see fit.
89 Sometimes it is necessary to include small portions of the stylesheets within
90 your source distribution to make building simpler for end users and packagers.
91 As a special exception to the GNU General Public License, if you distribute
92 the stylesheets as part of a program that contains a configuration script
93 generated by Autoconf, you may include those stylesheets under the same
94 distribution terms that you use for the rest of that program.
99 This package contains a number of images that are used in the formatted
100 output. They were created primarily by Josef Vybíral. These images are
101 licensed under the terms of the GNU GPL.
103 As a special exception to the GNU General Public License, if you distribute
104 copies of your document formatted by the tools in this package, you may
105 redistribute unmodified copies of any images used or referenced in that
106 formatted copy without restriction.

109 GNU GENERAL PUBLIC LICENSE
112 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
113 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
114 Everyone is permitted to copy and distribute verbatim copies
115 of this license document, but changing it is not allowed.
119 The licenses for most software are designed to take away your
120 freedom to share and change it. By contrast, the GNU General Public
121 License is intended to guarantee your freedom to share and change free
122 software--to make sure the software is free for all its users. This
123 General Public License applies to most of the Free Software
124 Foundation's software and to any other program whose authors commit to
125 using it. (Some other Free Software Foundation software is covered by
126 the GNU Library General Public License instead.) You can apply it to
129 When we speak of free software, we are referring to freedom, not
130 price. Our General Public Licenses are designed to make sure that you
131 have the freedom to distribute copies of free software (and charge for
132 this service if you wish), that you receive source code or can get it
133 if you want it, that you can change the software or use pieces of it
134 in new free programs; and that you know you can do these things.
136 To protect your rights, we need to make restrictions that forbid
137 anyone to deny you these rights or to ask you to surrender the rights.
138 These restrictions translate to certain responsibilities for you if you
139 distribute copies of the software, or if you modify it.
141 For example, if you distribute copies of such a program, whether
142 gratis or for a fee, you must give the recipients all the rights that
143 you have. You must make sure that they, too, receive or can get the
144 source code. And you must show them these terms so they know their
147 We protect your rights with two steps: (1) copyright the software, and
148 (2) offer you this license which gives you legal permission to copy,
149 distribute and/or modify the software.
151 Also, for each author's protection and ours, we want to make certain
152 that everyone understands that there is no warranty for this free
153 software. If the software is modified by someone else and passed on, we
154 want its recipients to know that what they have is not the original, so
155 that any problems introduced by others will not reflect on the original
156 authors' reputations.
158 Finally, any free program is threatened constantly by software
159 patents. We wish to avoid the danger that redistributors of a free
160 program will individually obtain patent licenses, in effect making the
161 program proprietary. To prevent this, we have made it clear that any
162 patent must be licensed for everyone's free use or not licensed at all.
164 The precise terms and conditions for copying, distribution and
167 GNU GENERAL PUBLIC LICENSE
168 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
170 0. This License applies to any program or other work which contains
171 a notice placed by the copyright holder saying it may be distributed
172 under the terms of this General Public License. The "Program", below,
173 refers to any such program or work, and a "work based on the Program"
174 means either the Program or any derivative work under copyright law:
175 that is to say, a work containing the Program or a portion of it,
176 either verbatim or with modifications and/or translated into another
177 language. (Hereinafter, translation is included without limitation in
178 the term "modification".) Each licensee is addressed as "you".
180 Activities other than copying, distribution and modification are not
181 covered by this License; they are outside its scope. The act of
182 running the Program is not restricted, and the output from the Program
183 is covered only if its contents constitute a work based on the
184 Program (independent of having been made by running the Program).
185 Whether that is true depends on what the Program does.
187 1. You may copy and distribute verbatim copies of the Program's
188 source code as you receive it, in any medium, provided that you
189 conspicuously and appropriately publish on each copy an appropriate
190 copyright notice and disclaimer of warranty; keep intact all the
191 notices that refer to this License and to the absence of any warranty;
192 and give any other recipients of the Program a copy of this License
193 along with the Program.
195 You may charge a fee for the physical act of transferring a copy, and
196 you may at your option offer warranty protection in exchange for a fee.
198 2. You may modify your copy or copies of the Program or any portion
199 of it, thus forming a work based on the Program, and copy and
200 distribute such modifications or work under the terms of Section 1
201 above, provided that you also meet all of these conditions:
203 a) You must cause the modified files to carry prominent notices
204 stating that you changed the files and the date of any change.
206 b) You must cause any work that you distribute or publish, that in
207 whole or in part contains or is derived from the Program or any
208 part thereof, to be licensed as a whole at no charge to all third
209 parties under the terms of this License.
211 c) If the modified program normally reads commands interactively
212 when run, you must cause it, when started running for such
213 interactive use in the most ordinary way, to print or display an
214 announcement including an appropriate copyright notice and a
215 notice that there is no warranty (or else, saying that you provide
216 a warranty) and that users may redistribute the program under
217 these conditions, and telling the user how to view a copy of this
218 License. (Exception: if the Program itself is interactive but
219 does not normally print such an announcement, your work based on
220 the Program is not required to print an announcement.)
222 These requirements apply to the modified work as a whole. If
223 identifiable sections of that work are not derived from the Program,
224 and can be reasonably considered independent and separate works in
225 themselves, then this License, and its terms, do not apply to those
226 sections when you distribute them as separate works. But when you
227 distribute the same sections as part of a whole which is a work based
228 on the Program, the distribution of the whole must be on the terms of
229 this License, whose permissions for other licensees extend to the
230 entire whole, and thus to each and every part regardless of who wrote it.
232 Thus, it is not the intent of this section to claim rights or contest
233 your rights to work written entirely by you; rather, the intent is to
234 exercise the right to control the distribution of derivative or
235 collective works based on the Program.
237 In addition, mere aggregation of another work not based on the Program
238 with the Program (or with a work based on the Program) on a volume of
239 a storage or distribution medium does not bring the other work under
240 the scope of this License.
242 3. You may copy and distribute the Program (or a work based on it,
243 under Section 2) in object code or executable form under the terms of
244 Sections 1 and 2 above provided that you also do one of the following:
246 a) Accompany it with the complete corresponding machine-readable
247 source code, which must be distributed under the terms of Sections
248 1 and 2 above on a medium customarily used for software interchange; or,
250 b) Accompany it with a written offer, valid for at least three
251 years, to give any third party, for a charge no more than your
252 cost of physically performing source distribution, a complete
253 machine-readable copy of the corresponding source code, to be
254 distributed under the terms of Sections 1 and 2 above on a medium
255 customarily used for software interchange; or,
257 c) Accompany it with the information you received as to the offer
258 to distribute corresponding source code. (This alternative is
259 allowed only for noncommercial distribution and only if you
260 received the program in object code or executable form with such
261 an offer, in accord with Subsection b above.)
263 The source code for a work means the preferred form of the work for
264 making modifications to it. For an executable work, complete source
265 code means all the source code for all modules it contains, plus any
266 associated interface definition files, plus the scripts used to
267 control compilation and installation of the executable. However, as a
268 special exception, the source code distributed need not include
269 anything that is normally distributed (in either source or binary
270 form) with the major components (compiler, kernel, and so on) of the
271 operating system on which the executable runs, unless that component
272 itself accompanies the executable.
274 If distribution of executable or object code is made by offering
275 access to copy from a designated place, then offering equivalent
276 access to copy the source code from the same place counts as
277 distribution of the source code, even though third parties are not
278 compelled to copy the source along with the object code.
280 4. You may not copy, modify, sublicense, or distribute the Program
281 except as expressly provided under this License. Any attempt
282 otherwise to copy, modify, sublicense or distribute the Program is
283 void, and will automatically terminate your rights under this License.
284 However, parties who have received copies, or rights, from you under
285 this License will not have their licenses terminated so long as such
286 parties remain in full compliance.
288 5. You are not required to accept this License, since you have not
289 signed it. However, nothing else grants you permission to modify or
290 distribute the Program or its derivative works. These actions are
291 prohibited by law if you do not accept this License. Therefore, by
292 modifying or distributing the Program (or any work based on the
293 Program), you indicate your acceptance of this License to do so, and
294 all its terms and conditions for copying, distributing or modifying
295 the Program or works based on it.
297 6. Each time you redistribute the Program (or any work based on the
298 Program), the recipient automatically receives a license from the
299 original licensor to copy, distribute or modify the Program subject to
300 these terms and conditions. You may not impose any further
301 restrictions on the recipients' exercise of the rights granted herein.
302 You are not responsible for enforcing compliance by third parties to
305 7. If, as a consequence of a court judgment or allegation of patent
306 infringement or for any other reason (not limited to patent issues),
307 conditions are imposed on you (whether by court order, agreement or
308 otherwise) that contradict the conditions of this License, they do not
309 excuse you from the conditions of this License. If you cannot
310 distribute so as to satisfy simultaneously your obligations under this
311 License and any other pertinent obligations, then as a consequence you
312 may not distribute the Program at all. For example, if a patent
313 license would not permit royalty-free redistribution of the Program by
314 all those who receive copies directly or indirectly through you, then
315 the only way you could satisfy both it and this License would be to
316 refrain entirely from distribution of the Program.
318 If any portion of this section is held invalid or unenforceable under
319 any particular circumstance, the balance of the section is intended to
320 apply and the section as a whole is intended to apply in other
323 It is not the purpose of this section to induce you to infringe any
324 patents or other property right claims or to contest validity of any
325 such claims; this section has the sole purpose of protecting the
326 integrity of the free software distribution system, which is
327 implemented by public license practices. Many people have made
328 generous contributions to the wide range of software distributed
329 through that system in reliance on consistent application of that
330 system; it is up to the author/donor to decide if he or she is willing
331 to distribute software through any other system and a licensee cannot
334 This section is intended to make thoroughly clear what is believed to
335 be a consequence of the rest of this License.
337 8. If the distribution and/or use of the Program is restricted in
338 certain countries either by patents or by copyrighted interfaces, the
339 original copyright holder who places the Program under this License
340 may add an explicit geographical distribution limitation excluding
341 those countries, so that distribution is permitted only in or among
342 countries not thus excluded. In such case, this License incorporates
343 the limitation as if written in the body of this License.
345 9. The Free Software Foundation may publish revised and/or new versions
346 of the General Public License from time to time. Such new versions will
347 be similar in spirit to the present version, but may differ in detail to
348 address new problems or concerns.
350 Each version is given a distinguishing version number. If the Program
351 specifies a version number of this License which applies to it and "any
352 later version", you have the option of following the terms and conditions
353 either of that version or of any later version published by the Free
354 Software Foundation. If the Program does not specify a version number of
355 this License, you may choose any version ever published by the Free Software
358 10. If you wish to incorporate parts of the Program into other free
359 programs whose distribution conditions are different, write to the author
360 to ask for permission. For software which is copyrighted by the Free
361 Software Foundation, write to the Free Software Foundation; we sometimes
362 make exceptions for this. Our decision will be guided by the two goals
363 of preserving the free status of all derivatives of our free software and
364 of promoting the sharing and reuse of software generally.
368 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
369 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
370 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
371 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
372 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
373 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
374 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
375 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
376 REPAIR OR CORRECTION.
378 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
379 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
380 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
381 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
382 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
383 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
384 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
385 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
386 POSSIBILITY OF SUCH DAMAGES.
388 END OF TERMS AND CONDITIONS
390 How to Apply These Terms to Your New Programs
392 If you develop a new program, and you want it to be of the greatest
393 possible use to the public, the best way to achieve this is to make it
394 free software which everyone can redistribute and change under these terms.
396 To do so, attach the following notices to the program. It is safest
397 to attach them to the start of each source file to most effectively
398 convey the exclusion of warranty; and each file should have at least
399 the "copyright" line and a pointer to where the full notice is found.
401 <one line to give the program's name and a brief idea of what it does.>
402 Copyright (C) <year> <name of author>
404 This program is free software; you can redistribute it and/or modify
405 it under the terms of the GNU General Public License as published by
406 the Free Software Foundation; either version 2 of the License, or
407 (at your option) any later version.
409 This program is distributed in the hope that it will be useful,
410 but WITHOUT ANY WARRANTY; without even the implied warranty of
411 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
412 GNU General Public License for more details.
414 You should have received a copy of the GNU General Public License
415 along with this program; if not, write to the Free Software
416 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
419 Also add information on how to contact you by electronic and paper mail.
421 If the program is interactive, make it output a short notice like this
422 when it starts in an interactive mode:
424 Gnomovision version 69, Copyright (C) year name of author
425 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
426 This is free software, and you are welcome to redistribute it
427 under certain conditions; type `show c' for details.
429 The hypothetical commands `show w' and `show c' should show the appropriate
430 parts of the General Public License. Of course, the commands you use may
431 be called something other than `show w' and `show c'; they could even be
432 mouse-clicks or menu items--whatever suits your program.
434 You should also get your employer (if you work as a programmer) or your
435 school, if any, to sign a "copyright disclaimer" for the program, if
436 necessary. Here is a sample; alter the names:
438 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
439 `Gnomovision' (which makes passes at compilers) written by James Hacker.

442 Ty Coon, President of Vice
444 This General Public License does not permit incorporating your program into
445 proprietary programs. If your program is a subroutine library, you may
446 consider it more useful to permit linking proprietary applications with the
447 library. If this is what you want to do, use the GNU Library General
448 Public License instead of this License.
449 ===============================================================================
450 GNU LESSER GENERAL PUBLIC LICENSE
451 Version 2.1, February 1999
453 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
454 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
455 Everyone is permitted to copy and distribute verbatim copies
456 of this license document, but changing it is not allowed.
458 [This is the first released version of the Lesser GPL. It also counts
459 as the successor of the GNU Library Public License, version 2, hence
460 the version number 2.1.]
464 The licenses for most software are designed to take away your
465 freedom to share and change it. By contrast, the GNU General Public
466 Licenses are intended to guarantee your freedom to share and change
467 free software--to make sure the software is free for all its users.
469 This license, the Lesser General Public License, applies to some
470 specially designated software packages--typically libraries--of the
471 Free Software Foundation and other authors who decide to use it. You
472 can use it too, but we suggest you first think carefully about whether
473 this license or the ordinary General Public License is the better
474 strategy to use in any particular case, based on the explanations below.
476 When we speak of free software, we are referring to freedom of use,
477 not price. Our General Public Licenses are designed to make sure that
478 you have the freedom to distribute copies of free software (and charge
479 for this service if you wish); that you receive source code or can get
480 it if you want it; that you can change the software and use pieces of
481 it in new free programs; and that you are informed that you can do
484 To protect your rights, we need to make restrictions that forbid
485 distributors to deny you these rights or to ask you to surrender these
486 rights. These restrictions translate to certain responsibilities for
487 you if you distribute copies of the library or if you modify it.
489 For example, if you distribute copies of the library, whether gratis
490 or for a fee, you must give the recipients all the rights that we gave
491 you. You must make sure that they, too, receive or can get the source
492 code. If you link other code with the library, you must provide
493 complete object files to the recipients, so that they can relink them
494 with the library after making changes to the library and recompiling
495 it. And you must show them these terms so they know their rights.
497 We protect your rights with a two-step method: (1) we copyright the
498 library, and (2) we offer you this license, which gives you legal
499 permission to copy, distribute and/or modify the library.
501 To protect each distributor, we want to make it very clear that
502 there is no warranty for the free library. Also, if the library is
503 modified by someone else and passed on, the recipients should know
504 that what they have is not the original version, so that the original
505 author's reputation will not be affected by problems that might be
506 introduced by others.
508 Finally, software patents pose a constant threat to the existence of
509 any free program. We wish to make sure that a company cannot
510 effectively restrict the users of a free program by obtaining a
511 restrictive license from a patent holder. Therefore, we insist that
512 any patent license obtained for a version of the library must be
513 consistent with the full freedom of use specified in this license.
515 Most GNU software, including some libraries, is covered by the
516 ordinary GNU General Public License. This license, the GNU Lesser
517 General Public License, applies to certain designated libraries, and
518 is quite different from the ordinary General Public License. We use
519 this license for certain libraries in order to permit linking those
520 libraries into non-free programs.
522 When a program is linked with a library, whether statically or using
523 a shared library, the combination of the two is legally speaking a
524 combined work, a derivative of the original library. The ordinary
525 General Public License therefore permits such linking only if the
526 entire combination fits its criteria of freedom. The Lesser General
527 Public License permits more lax criteria for linking other code with
530 We call this license the "Lesser" General Public License because it
531 does Less to protect the user's freedom than the ordinary General
532 Public License. It also provides other free software developers Less
533 of an advantage over competing non-free programs. These disadvantages
534 are the reason we use the ordinary General Public License for many
535 libraries. However, the Lesser license provides advantages in certain
536 special circumstances.
538 For example, on rare occasions, there may be a special need to
539 encourage the widest possible use of a certain library, so that it becomes
540 a de-facto standard. To achieve this, non-free programs must be
541 allowed to use the library. A more frequent case is that a free
542 library does the same job as widely used non-free libraries. In this
543 case, there is little to gain by limiting the free library to free
544 software only, so we use the Lesser General Public License.
546 In other cases, permission to use a particular library in non-free
547 programs enables a greater number of people to use a large body of
548 free software. For example, permission to use the GNU C Library in
549 non-free programs enables many more people to use the whole GNU
550 operating system, as well as its variant, the GNU/Linux operating
553 Although the Lesser General Public License is Less protective of the
554 users' freedom, it does ensure that the user of a program that is
555 linked with the Library has the freedom and the wherewithal to run
556 that program using a modified version of the Library.
558 The precise terms and conditions for copying, distribution and
559 modification follow. Pay close attention to the difference between a
560 "work based on the library" and a "work that uses the library". The
561 former contains code derived from the library, whereas the latter must
562 be combined with the library in order to run.
564 GNU LESSER GENERAL PUBLIC LICENSE
565 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
567 0. This License Agreement applies to any software library or other
568 program which contains a notice placed by the copyright holder or
569 other authorized party saying it may be distributed under the terms of
570 this Lesser General Public License (also called "this License").
571 Each licensee is addressed as "you".
573 A "library" means a collection of software functions and/or data
574 prepared so as to be conveniently linked with application programs
575 (which use some of those functions and data) to form executables.
577 The "Library", below, refers to any such software library or work
578 which has been distributed under these terms. A "work based on the
579 Library" means either the Library or any derivative work under
580 copyright law: that is to say, a work containing the Library or a
581 portion of it, either verbatim or with modifications and/or translated
582 straightforwardly into another language. (Hereinafter, translation is
583 included without limitation in the term "modification".)
585 "Source code" for a work means the preferred form of the work for
586 making modifications to it. For a library, complete source code means
587 all the source code for all modules it contains, plus any associated
588 interface definition files, plus the scripts used to control compilation
589 and installation of the library.
591 Activities other than copying, distribution and modification are not
592 covered by this License; they are outside its scope. The act of
593 running a program using the Library is not restricted, and output from
594 such a program is covered only if its contents constitute a work based
595 on the Library (independent of the use of the Library in a tool for
596 writing it). Whether that is true depends on what the Library does
597 and what the program that uses the Library does.
599 1. You may copy and distribute verbatim copies of the Library's
600 complete source code as you receive it, in any medium, provided that
601 you conspicuously and appropriately publish on each copy an
602 appropriate copyright notice and disclaimer of warranty; keep intact
603 all the notices that refer to this License and to the absence of any
604 warranty; and distribute a copy of this License along with the
607 You may charge a fee for the physical act of transferring a copy,
608 and you may at your option offer warranty protection in exchange for a
611 2. You may modify your copy or copies of the Library or any portion
612 of it, thus forming a work based on the Library, and copy and
613 distribute such modifications or work under the terms of Section 1
614 above, provided that you also meet all of these conditions:
616 a) The modified work must itself be a software library.
618 b) You must cause the files modified to carry prominent notices
619 stating that you changed the files and the date of any change.
621 c) You must cause the whole of the work to be licensed at no
622 charge to all third parties under the terms of this License.
624 d) If a facility in the modified Library refers to a function or a
625 table of data to be supplied by an application program that uses
626 the facility, other than as an argument passed when the facility
627 is invoked, then you must make a good faith effort to ensure that,
628 in the event an application does not supply such function or
629 table, the facility still operates, and performs whatever part of
630 its purpose remains meaningful.
632 (For example, a function in a library to compute square roots has
633 a purpose that is entirely well-defined independent of the
634 application. Therefore, Subsection 2d requires that any
635 application-supplied function or table used by this function must
636 be optional: if the application does not supply it, the square
637 root function must still compute square roots.)
639 These requirements apply to the modified work as a whole. If
640 identifiable sections of that work are not derived from the Library,
641 and can be reasonably considered independent and separate works in
642 themselves, then this License, and its terms, do not apply to those
643 sections when you distribute them as separate works. But when you
644 distribute the same sections as part of a whole which is a work based
645 on the Library, the distribution of the whole must be on the terms of
646 this License, whose permissions for other licensees extend to the
647 entire whole, and thus to each and every part regardless of who wrote
650 Thus, it is not the intent of this section to claim rights or contest
651 your rights to work written entirely by you; rather, the intent is to
652 exercise the right to control the distribution of derivative or
653 collective works based on the Library.
655 In addition, mere aggregation of another work not based on the Library
656 with the Library (or with a work based on the Library) on a volume of
657 a storage or distribution medium does not bring the other work under
658 the scope of this License.
660 3. You may opt to apply the terms of the ordinary GNU General Public
661 License instead of this License to a given copy of the Library. To do
662 this, you must alter all the notices that refer to this License, so
663 that they refer to the ordinary GNU General Public License, version 2,
664 instead of to this License. (If a newer version than version 2 of the
665 ordinary GNU General Public License has appeared, then you can specify
666 that version instead if you wish.) Do not make any other change in
669 Once this change is made in a given copy, it is irreversible for
670 that copy, so the ordinary GNU General Public License applies to all
671 subsequent copies and derivative works made from that copy.
673 This option is useful when you wish to copy part of the code of
674 the Library into a program that is not a library.
676 4. You may copy and distribute the Library (or a portion or
677 derivative of it, under Section 2) in object code or executable form
678 under the terms of Sections 1 and 2 above provided that you accompany
679 it with the complete corresponding machine-readable source code, which
680 must be distributed under the terms of Sections 1 and 2 above on a
681 medium customarily used for software interchange.
683 If distribution of object code is made by offering access to copy
684 from a designated place, then offering equivalent access to copy the
685 source code from the same place satisfies the requirement to
686 distribute the source code, even though third parties are not
687 compelled to copy the source along with the object code.
689 5. A program that contains no derivative of any portion of the
690 Library, but is designed to work with the Library by being compiled or
691 linked with it, is called a "work that uses the Library". Such a
692 work, in isolation, is not a derivative work of the Library, and
693 therefore falls outside the scope of this License.
695 However, linking a "work that uses the Library" with the Library
696 creates an executable that is a derivative of the Library (because it
697 contains portions of the Library), rather than a "work that uses the
698 library". The executable is therefore covered by this License.
699 Section 6 states terms for distribution of such executables.
701 When a "work that uses the Library" uses material from a header file
702 that is part of the Library, the object code for the work may be a
703 derivative work of the Library even though the source code is not.
704 Whether this is true is especially significant if the work can be
705 linked without the Library, or if the work is itself a library. The
706 threshold for this to be true is not precisely defined by law.
708 If such an object file uses only numerical parameters, data
709 structure layouts and accessors, and small macros and small inline
710 functions (ten lines or less in length), then the use of the object
711 file is unrestricted, regardless of whether it is legally a derivative
712 work. (Executables containing this object code plus portions of the
713 Library will still fall under Section 6.)
715 Otherwise, if the work is a derivative of the Library, you may
716 distribute the object code for the work under the terms of Section 6.
717 Any executables containing that work also fall under Section 6,
718 whether or not they are linked directly with the Library itself.
720 6. As an exception to the Sections above, you may also combine or
721 link a "work that uses the Library" with the Library to produce a
722 work containing portions of the Library, and distribute that work
723 under terms of your choice, provided that the terms permit
724 modification of the work for the customer's own use and reverse
725 engineering for debugging such modifications.
727 You must give prominent notice with each copy of the work that the
728 Library is used in it and that the Library and its use are covered by
729 this License. You must supply a copy of this License. If the work
730 during execution displays copyright notices, you must include the
731 copyright notice for the Library among them, as well as a reference
732 directing the user to the copy of this License. Also, you must do one
735 a) Accompany the work with the complete corresponding
736 machine-readable source code for the Library including whatever
737 changes were used in the work (which must be distributed under
738 Sections 1 and 2 above); and, if the work is an executable linked
739 with the Library, with the complete machine-readable "work that
740 uses the Library", as object code and/or source code, so that the
741 user can modify the Library and then relink to produce a modified
742 executable containing the modified Library. (It is understood
743 that the user who changes the contents of definitions files in the
744 Library will not necessarily be able to recompile the application
745 to use the modified definitions.)
747 b) Use a suitable shared library mechanism for linking with the
748 Library. A suitable mechanism is one that (1) uses at run time a
749 copy of the library already present on the user's computer system,
750 rather than copying library functions into the executable, and (2)
751 will operate properly with a modified version of the library, if
752 the user installs one, as long as the modified version is
753 interface-compatible with the version that the work was made with.
755 c) Accompany the work with a written offer, valid for at
756 least three years, to give the same user the materials
757 specified in Subsection 6a, above, for a charge no more
758 than the cost of performing this distribution.
760 d) If distribution of the work is made by offering access to copy
761 from a designated place, offer equivalent access to copy the above
762 specified materials from the same place.
764 e) Verify that the user has already received a copy of these
765 materials or that you have already sent this user a copy.
767 For an executable, the required form of the "work that uses the
768 Library" must include any data and utility programs needed for
769 reproducing the executable from it. However, as a special exception,
770 the materials to be distributed need not include anything that is
771 normally distributed (in either source or binary form) with the major
772 components (compiler, kernel, and so on) of the operating system on
773 which the executable runs, unless that component itself accompanies
776 It may happen that this requirement contradicts the license
777 restrictions of other proprietary libraries that do not normally
778 accompany the operating system. Such a contradiction means you cannot
779 use both them and the Library together in an executable that you
782 7. You may place library facilities that are a work based on the
783 Library side-by-side in a single library together with other library
784 facilities not covered by this License, and distribute such a combined
785 library, provided that the separate distribution of the work based on
786 the Library and of the other library facilities is otherwise
787 permitted, and provided that you do these two things:
789 a) Accompany the combined library with a copy of the same work
790 based on the Library, uncombined with any other library
791 facilities. This must be distributed under the terms of the
794 b) Give prominent notice with the combined library of the fact
795 that part of it is a work based on the Library, and explaining
796 where to find the accompanying uncombined form of the same work.
798 8. You may not copy, modify, sublicense, link with, or distribute
799 the Library except as expressly provided under this License. Any
800 attempt otherwise to copy, modify, sublicense, link with, or
801 distribute the Library is void, and will automatically terminate your
802 rights under this License. However, parties who have received copies,
803 or rights, from you under this License will not have their licenses
804 terminated so long as such parties remain in full compliance.
806 9. You are not required to accept this License, since you have not
807 signed it. However, nothing else grants you permission to modify or
808 distribute the Library or its derivative works. These actions are
809 prohibited by law if you do not accept this License. Therefore, by
810 modifying or distributing the Library (or any work based on the
811 Library), you indicate your acceptance of this License to do so, and
812 all its terms and conditions for copying, distributing or modifying
813 the Library or works based on it.
815 10. Each time you redistribute the Library (or any work based on the
816 Library), the recipient automatically receives a license from the
817 original licensor to copy, distribute, link with or modify the Library
818 subject to these terms and conditions. You may not impose any further
819 restrictions on the recipients' exercise of the rights granted herein.
820 You are not responsible for enforcing compliance by third parties with
823 11. If, as a consequence of a court judgment or allegation of patent
824 infringement or for any other reason (not limited to patent issues),
825 conditions are imposed on you (whether by court order, agreement or
826 otherwise) that contradict the conditions of this License, they do not
827 excuse you from the conditions of this License. If you cannot
828 distribute so as to satisfy simultaneously your obligations under this
829 License and any other pertinent obligations, then as a consequence you
830 may not distribute the Library at all. For example, if a patent
831 license would not permit royalty-free redistribution of the Library by
832 all those who receive copies directly or indirectly through you, then
833 the only way you could satisfy both it and this License would be to
834 refrain entirely from distribution of the Library.
836 If any portion of this section is held invalid or unenforceable under any
837 particular circumstance, the balance of the section is intended to apply,
838 and the section as a whole is intended to apply in other circumstances.
840 It is not the purpose of this section to induce you to infringe any
841 patents or other property right claims or to contest validity of any
842 such claims; this section has the sole purpose of protecting the
843 integrity of the free software distribution system which is
844 implemented by public license practices. Many people have made
845 generous contributions to the wide range of software distributed
846 through that system in reliance on consistent application of that
847 system; it is up to the author/donor to decide if he or she is willing
848 to distribute software through any other system and a licensee cannot
851 This section is intended to make thoroughly clear what is believed to
852 be a consequence of the rest of this License.
854 12. If the distribution and/or use of the Library is restricted in
855 certain countries either by patents or by copyrighted interfaces, the
856 original copyright holder who places the Library under this License may add
857 an explicit geographical distribution limitation excluding those countries,
858 so that distribution is permitted only in or among countries not thus
859 excluded. In such case, this License incorporates the limitation as if
860 written in the body of this License.
862 13. The Free Software Foundation may publish revised and/or new
863 versions of the Lesser General Public License from time to time.
864 Such new versions will be similar in spirit to the present version,
865 but may differ in detail to address new problems or concerns.
867 Each version is given a distinguishing version number. If the Library
868 specifies a version number of this License which applies to it and
869 "any later version", you have the option of following the terms and
870 conditions either of that version or of any later version published by
871 the Free Software Foundation. If the Library does not specify a
872 license version number, you may choose any version ever published by
873 the Free Software Foundation.
875 14. If you wish to incorporate parts of the Library into other free
876 programs whose distribution conditions are incompatible with these,
877 write to the author to ask for permission. For software which is
878 copyrighted by the Free Software Foundation, write to the Free
879 Software Foundation; we sometimes make exceptions for this. Our
880 decision will be guided by the two goals of preserving the free status
881 of all derivatives of our free software and of promoting the sharing
882 and reuse of software generally.
886 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
887 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
888 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
889 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
890 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
891 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
892 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
893 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
894 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
896 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
897 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
898 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
899 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
900 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
901 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
902 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
903 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
904 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
907 END OF TERMS AND CONDITIONS
909 How to Apply These Terms to Your New Libraries
911 If you develop a new library, and you want it to be of the greatest
912 possible use to the public, we recommend making it free software that
913 everyone can redistribute and change. You can do so by permitting
914 redistribution under these terms (or, alternatively, under the terms of the
915 ordinary General Public License).
917 To apply these terms, attach the following notices to the library. It is
918 safest to attach them to the start of each source file to most effectively
919 convey the exclusion of warranty; and each file should have at least the
920 "copyright" line and a pointer to where the full notice is found.
922 <one line to give the library's name and a brief idea of what it does.>
923 Copyright (C) <year> <name of author>
925 This library is free software; you can redistribute it and/or
926 modify it under the terms of the GNU Lesser General Public
927 License as published by the Free Software Foundation; either
928 version 2.1 of the License, or (at your option) any later version.
930 This library is distributed in the hope that it will be useful,
931 but WITHOUT ANY WARRANTY; without even the implied warranty of
932 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
933 Lesser General Public License for more details.
935 You should have received a copy of the GNU Lesser General Public
936 License along with this library; if not, write to the Free Software
937 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
939 Also add information on how to contact you by electronic and paper mail.
941 You should also get your employer (if you work as a programmer) or your
942 school, if any, to sign a "copyright disclaimer" for the library, if
943 necessary. Here is a sample; alter the names:
