6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.

9[This is the first released version of the library GPL. It is
10 numbered 2 because it goes with version 2 of the ordinary GPL.]
11
12 Preamble
13
14 The licenses for most software are designed to take away your
15freedom to share and change it. By contrast, the GNU General Public
16Licenses are intended to guarantee your freedom to share and change
17free software--to make sure the software is free for all its users.
18
19 This license, the Library General Public License, applies to some
20specially designated Free Software Foundation software, and to any
21other libraries whose authors decide to use it. You can use it for
22your libraries, too.
23
24 When we speak of free software, we are referring to freedom, not
25price. Our General Public Licenses are designed to make sure that you
26have the freedom to distribute copies of free software (and charge for
27this service if you wish), that you receive source code or can get it
28if you want it, that you can change the software or use pieces of it
29in new free programs; and that you know you can do these things.
30
31 To protect your rights, we need to make restrictions that forbid
32anyone to deny you these rights or to ask you to surrender the rights.
33These restrictions translate to certain responsibilities for you if
34you distribute copies of the library, or if you modify it.
35
36 For example, if you distribute copies of the library, whether gratis
37or for a fee, you must give the recipients all the rights that we gave
38you. You must make sure that they, too, receive or can get the source
39code. If you link a program with the library, you must provide
40complete object files to the recipients so that they can relink them
41with the library, after making changes to the library and recompiling
42it. And you must show them these terms so they know their rights.
43
44 Our method of protecting your rights has two steps: (1) copyright
45the library, and (2) offer you this license which gives you legal
46permission to copy, distribute and/or modify the library.
47
48 Also, for each distributor's protection, we want to make certain
49that everyone understands that there is no warranty for this free
50library. If the library is modified by someone else and passed on, we
51want its recipients to know that what they have is not the original
52version, so that any problems introduced by others will not reflect on
53the original authors' reputations.
54
55
56 Finally, any free program is threatened constantly by software
57patents. We wish to avoid the danger that companies distributing free
58software will individually obtain patent licenses, thus in effect
59transforming the program into proprietary software. To prevent this,
60we have made it clear that any patent must be licensed for everyone's
61free use or not licensed at all.
62
63 Most GNU software, including some libraries, is covered by the ordinary
64GNU General Public License, which was designed for utility programs. This
65license, the GNU Library General Public License, applies to certain
66designated libraries. This license is quite different from the ordinary
67one; be sure to read it in full, and don't assume that anything in it is
68the same as in the ordinary license.
69
70 The reason we have a separate public license for some libraries is that
71they blur the distinction we usually make between modifying or adding to a
72program and simply using it. Linking a program with a library, without
73changing the library, is in some sense simply using the library, and is
74analogous to running a utility program or application program. However, in
75a textual and legal sense, the linked executable is a combined work, a
76derivative of the original library, and the ordinary General Public License
77treats it as such.
78
79 Because of this blurred distinction, using the ordinary General
80Public License for libraries did not effectively promote software
81sharing, because most developers did not use the libraries. We
82concluded that weaker conditions might promote sharing better.
83
84 However, unrestricted linking of non-free programs would deprive the
85users of those programs of all benefit from the free status of the
86libraries themselves. This Library General Public License is intended to
87permit developers of non-free programs to use free libraries, while
88preserving your freedom as a user of such programs to change the free
89libraries that are incorporated in them. (We have not seen how to achieve
90this as regards changes in header files, but we have achieved it as regards
91changes in the actual functions of the Library.) The hope is that this
92will lead to faster development of free libraries.
93
94 The precise terms and conditions for copying, distribution and
95modification follow. Pay close attention to the difference between a
96"work based on the library" and a "work that uses the library". The
97former contains code derived from the library, while the latter only
98works together with the library.
99
100 Note that it is possible for a library to be covered by the ordinary
101General Public License rather than by this special one.
102
103
104 GNU LIBRARY GENERAL PUBLIC LICENSE
105 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
106
107 0. This License Agreement applies to any software library which
108contains a notice placed by the copyright holder or other authorized
109party saying it may be distributed under the terms of this Library
110General Public License (also called "this License"). Each licensee is
111addressed as "you".
112
113 A "library" means a collection of software functions and/or data
114prepared so as to be conveniently linked with application programs
115(which use some of those functions and data) to form executables.
116
117 The "Library", below, refers to any such software library or work
118which has been distributed under these terms. A "work based on the
119Library" means either the Library or any derivative work under
120copyright law: that is to say, a work containing the Library or a
121portion of it, either verbatim or with modifications and/or translated
122straightforwardly into another language. (Hereinafter, translation is
123included without limitation in the term "modification".)
124
125 "Source code" for a work means the preferred form of the work for
126making modifications to it. For a library, complete source code means
127all the source code for all modules it contains, plus any associated
128interface definition files, plus the scripts used to control compilation
129and installation of the library.
130
131 Activities other than copying, distribution and modification are not
132covered by this License; they are outside its scope. The act of
133running a program using the Library is not restricted, and output from
134such a program is covered only if its contents constitute a work based
135on the Library (independent of the use of the Library in a tool for
136writing it). Whether that is true depends on what the Library does
137and what the program that uses the Library does.
138
139 1. You may copy and distribute verbatim copies of the Library's
140complete source code as you receive it, in any medium, provided that
141you conspicuously and appropriately publish on each copy an
142appropriate copyright notice and disclaimer of warranty; keep intact
143all the notices that refer to this License and to the absence of any
144warranty; and distribute a copy of this License along with the
145Library.
146
147 You may charge a fee for the physical act of transferring a copy,
148and you may at your option offer warranty protection in exchange for a
149fee.
150
151
152 2. You may modify your copy or copies of the Library or any portion
153of it, thus forming a work based on the Library, and copy and
154distribute such modifications or work under the terms of Section 1
155above, provided that you also meet all of these conditions:
156
157 a) The modified work must itself be a software library.
158
159 b) You must cause the files modified to carry prominent notices
160 stating that you changed the files and the date of any change.
161
162 c) You must cause the whole of the work to be licensed at no
163 charge to all third parties under the terms of this License.
164
165 d) If a facility in the modified Library refers to a function or a
166 table of data to be supplied by an application program that uses
167 the facility, other than as an argument passed when the facility
168 is invoked, then you must make a good faith effort to ensure that,
169 in the event an application does not supply such function or
170 table, the facility still operates, and performs whatever part of
171 its purpose remains meaningful.
172
173 (For example, a function in a library to compute square roots has
174 a purpose that is entirely well-defined independent of the
175 application. Therefore, Subsection 2d requires that any
176 application-supplied function or table used by this function must
177 be optional: if the application does not supply it, the square
178 root function must still compute square roots.)
179
180These requirements apply to the modified work as a whole. If
181identifiable sections of that work are not derived from the Library,
182and can be reasonably considered independent and separate works in
183themselves, then this License, and its terms, do not apply to those
184sections when you distribute them as separate works. But when you
185distribute the same sections as part of a whole which is a work based
186on the Library, the distribution of the whole must be on the terms of
187this License, whose permissions for other licensees extend to the
188entire whole, and thus to each and every part regardless of who wrote
189it.
190
191Thus, it is not the intent of this section to claim rights or contest
192your rights to work written entirely by you; rather, the intent is to
193exercise the right to control the distribution of derivative or
194collective works based on the Library.
195
196In addition, mere aggregation of another work not based on the Library
197with the Library (or with a work based on the Library) on a volume of
198a storage or distribution medium does not bring the other work under
199the scope of this License.
200
201 3. You may opt to apply the terms of the ordinary GNU General Public
202License instead of this License to a given copy of the Library. To do
203this, you must alter all the notices that refer to this License, so
204that they refer to the ordinary GNU General Public License, version 2,
205instead of to this License. (If a newer version than version 2 of the
206ordinary GNU General Public License has appeared, then you can specify
207that version instead if you wish.) Do not make any other change in
208these notices.
209
210
211 Once this change is made in a given copy, it is irreversible for
212that copy, so the ordinary GNU General Public License applies to all
213subsequent copies and derivative works made from that copy.
214
215 This option is useful when you wish to copy part of the code of
216the Library into a program that is not a library.
217
218 4. You may copy and distribute the Library (or a portion or
219derivative of it, under Section 2) in object code or executable form
220under the terms of Sections 1 and 2 above provided that you accompany
221it with the complete corresponding machine-readable source code, which
222must be distributed under the terms of Sections 1 and 2 above on a
223medium customarily used for software interchange.
224
225 If distribution of object code is made by offering access to copy
226from a designated place, then offering equivalent access to copy the
227source code from the same place satisfies the requirement to
228distribute the source code, even though third parties are not
229compelled to copy the source along with the object code.
230
231 5. A program that contains no derivative of any portion of the
232Library, but is designed to work with the Library by being compiled or
233linked with it, is called a "work that uses the Library". Such a
234work, in isolation, is not a derivative work of the Library, and
235therefore falls outside the scope of this License.
236
237 However, linking a "work that uses the Library" with the Library
238creates an executable that is a derivative of the Library (because it
239contains portions of the Library), rather than a "work that uses the
240library". The executable is therefore covered by this License.
241Section 6 states terms for distribution of such executables.
242
243 When a "work that uses the Library" uses material from a header file
244that is part of the Library, the object code for the work may be a
245derivative work of the Library even though the source code is not.
246Whether this is true is especially significant if the work can be
247linked without the Library, or if the work is itself a library. The
248threshold for this to be true is not precisely defined by law.
249
250 If such an object file uses only numerical parameters, data
251structure layouts and accessors, and small macros and small inline
252functions (ten lines or less in length), then the use of the object
253file is unrestricted, regardless of whether it is legally a derivative
254work. (Executables containing this object code plus portions of the
255Library will still fall under Section 6.)
256
257 Otherwise, if the work is a derivative of the Library, you may
258distribute the object code for the work under the terms of Section 6.
259Any executables containing that work also fall under Section 6,
260whether or not they are linked directly with the Library itself.
261
262
263 6. As an exception to the Sections above, you may also compile or
264link a "work that uses the Library" with the Library to produce a
265work containing portions of the Library, and distribute that work
266under terms of your choice, provided that the terms permit
267modification of the work for the customer's own use and reverse
268engineering for debugging such modifications.
269
270 You must give prominent notice with each copy of the work that the
271Library is used in it and that the Library and its use are covered by
272this License. You must supply a copy of this License. If the work
273during execution displays copyright notices, you must include the
274copyright notice for the Library among them, as well as a reference
275directing the user to the copy of this License. Also, you must do one
276of these things:
277
278 a) Accompany the work with the complete corresponding
279 machine-readable source code for the Library including whatever
280 changes were used in the work (which must be distributed under
281 Sections 1 and 2 above); and, if the work is an executable linked
282 with the Library, with the complete machine-readable "work that
283 uses the Library", as object code and/or source code, so that the
284 user can modify the Library and then relink to produce a modified
285 executable containing the modified Library. (It is understood
286 that the user who changes the contents of definitions files in the
287 Library will not necessarily be able to recompile the application
288 to use the modified definitions.)
289
290 b) Accompany the work with a written offer, valid for at
291 least three years, to give the same user the materials
292 specified in Subsection 6a, above, for a charge no more
293 than the cost of performing this distribution.
294
295 c) If distribution of the work is made by offering access to copy
296 from a designated place, offer equivalent access to copy the above
297 specified materials from the same place.
298
299 d) Verify that the user has already received a copy of these
300 materials or that you have already sent this user a copy.
301
302 For an executable, the required form of the "work that uses the
303Library" must include any data and utility programs needed for
304reproducing the executable from it. However, as a special exception,
305the source code distributed need not include anything that is normally
306distributed (in either source or binary form) with the major
307components (compiler, kernel, and so on) of the operating system on
308which the executable runs, unless that component itself accompanies
309the executable.
310
311 It may happen that this requirement contradicts the license
312restrictions of other proprietary libraries that do not normally
313accompany the operating system. Such a contradiction means you cannot
314use both them and the Library together in an executable that you
315distribute.
316
317
318 7. You may place library facilities that are a work based on the
319Library side-by-side in a single library together with other library
320facilities not covered by this License, and distribute such a combined
321library, provided that the separate distribution of the work based on
322the Library and of the other library facilities is otherwise
323permitted, and provided that you do these two things:
324
325 a) Accompany the combined library with a copy of the same work
326 based on the Library, uncombined with any other library
327 facilities. This must be distributed under the terms of the
328 Sections above.
329
330 b) Give prominent notice with the combined library of the fact
331 that part of it is a work based on the Library, and explaining
332 where to find the accompanying uncombined form of the same work.
333
334 8. You may not copy, modify, sublicense, link with, or distribute
335the Library except as expressly provided under this License. Any
336attempt otherwise to copy, modify, sublicense, link with, or
337distribute the Library is void, and will automatically terminate your
338rights under this License. However, parties who have received copies,
339or rights, from you under this License will not have their licenses
340terminated so long as such parties remain in full compliance.
341
342 9. You are not required to accept this License, since you have not
343signed it. However, nothing else grants you permission to modify or
344distribute the Library or its derivative works. These actions are
345prohibited by law if you do not accept this License. Therefore, by
346modifying or distributing the Library (or any work based on the
347Library), you indicate your acceptance of this License to do so, and
348all its terms and conditions for copying, distributing or modifying
349the Library or works based on it.
350
351 10. Each time you redistribute the Library (or any work based on the
352Library), the recipient automatically receives a license from the
353original licensor to copy, distribute, link with or modify the Library
354subject to these terms and conditions. You may not impose any further
355restrictions on the recipients' exercise of the rights granted herein.
356You are not responsible for enforcing compliance by third parties to
357this License.
358
359
360 11. If, as a consequence of a court judgment or allegation of patent
361infringement or for any other reason (not limited to patent issues),
362conditions are imposed on you (whether by court order, agreement or
363otherwise) that contradict the conditions of this License, they do not
364excuse you from the conditions of this License. If you cannot
365distribute so as to satisfy simultaneously your obligations under this
366License and any other pertinent obligations, then as a consequence you
367may not distribute the Library at all. For example, if a patent
368license would not permit royalty-free redistribution of the Library by
369all those who receive copies directly or indirectly through you, then
370the only way you could satisfy both it and this License would be to
371refrain entirely from distribution of the Library.
372
373If any portion of this section is held invalid or unenforceable under any
374particular circumstance, the balance of the section is intended to apply,
375and the section as a whole is intended to apply in other circumstances.
376
377It is not the purpose of this section to induce you to infringe any
378patents or other property right claims or to contest validity of any
379such claims; this section has the sole purpose of protecting the
380integrity of the free software distribution system which is
381implemented by public license practices. Many people have made
382generous contributions to the wide range of software distributed
383through that system in reliance on consistent application of that
384system; it is up to the author/donor to decide if he or she is willing
385to distribute software through any other system and a licensee cannot
386impose that choice.
387
388This section is intended to make thoroughly clear what is believed to
389be a consequence of the rest of this License.
390
391 12. If the distribution and/or use of the Library is restricted in
392certain countries either by patents or by copyrighted interfaces, the
393original copyright holder who places the Library under this License may add
394an explicit geographical distribution limitation excluding those countries,
395so that distribution is permitted only in or among countries not thus
396excluded. In such case, this License incorporates the limitation as if
397written in the body of this License.
398
399 13. The Free Software Foundation may publish revised and/or new
400versions of the Library General Public License from time to time.
401Such new versions will be similar in spirit to the present version,
402but may differ in detail to address new problems or concerns.
403
404Each version is given a distinguishing version number. If the Library
405specifies a version number of this License which applies to it and
406"any later version", you have the option of following the terms and
407conditions either of that version or of any later version published by
408the Free Software Foundation. If the Library does not specify a
409license version number, you may choose any version ever published by
410the Free Software Foundation.
411
412
413 14. If you wish to incorporate parts of the Library into other free
414programs whose distribution conditions are incompatible with these,
415write to the author to ask for permission. For software which is
416copyrighted by the Free Software Foundation, write to the Free
417Software Foundation; we sometimes make exceptions for this. Our
418decision will be guided by the two goals of preserving the free status
419of all derivatives of our free software and of promoting the sharing
420and reuse of software generally.
421
422 NO WARRANTY
423
424 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
425WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
426EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
427OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
428KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
429IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
430PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
431LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
432THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
433
434 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
435WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
436AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
437FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
438CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
439LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
440RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
441FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
442SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
443DAMAGES.
444
445 END OF TERMS AND CONDITIONS
446
447
448 Appendix: How to Apply These Terms to Your New Libraries
449
450 If you develop a new library, and you want it to be of the greatest
451possible use to the public, we recommend making it free software that
452everyone can redistribute and change. You can do so by permitting
453redistribution under these terms (or, alternatively, under the terms of the
454ordinary General Public License).
455
456 To apply these terms, attach the following notices to the library. It is
457safest to attach them to the start of each source file to most effectively
458convey the exclusion of warranty; and each file should have at least the
459"copyright" line and a pointer to where the full notice is found.
460
461 <one line to give the library's name and a brief idea of what it does.>
462 Copyright (C) <year> <name of author>
463
464 This library is free software; you can redistribute it and/or
465 modify it under the terms of the GNU Library General Public
466 License as published by the Free Software Foundation; either
467 version 2 of the License, or (at your option) any later version.
468
469 This library is distributed in the hope that it will be useful,
470 but WITHOUT ANY WARRANTY; without even the implied warranty of
471 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
472 Library General Public License for more details.
473
474 You should have received a copy of the GNU Library General Public
475 License along with this library; if not, write to the Free
476 Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
477
478Also add information on how to contact you by electronic and paper mail.
479
480You should also get your employer (if you work as a programmer) or your
481school, if any, to sign a "copyright disclaimer" for the library, if
482necessary. Here is a sample; alter the names:
483
