- Version 2.1, February 1999
3
-
4
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
5
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
6
- Everyone is permitted to copy and distribute verbatim copies
7
- of this license document, but changing it is not allowed.
8
-
9
- [This is the first released version of the Lesser GPL. It also counts
10
- as the successor of the GNU Library Public License, version 2, hence
11
- the version number 2.1.]
12
-
13
- Preamble
14
-
15
- The licenses for most software are designed to take away your
16
- freedom to share and change it. By contrast, the GNU General Public
17
- Licenses are intended to guarantee your freedom to share and change
18
- free software--to make sure the software is free for all its users.
19
-
20
- This license, the Lesser General Public License, applies to some
21
- specially designated software packages--typically libraries--of the
22
- Free Software Foundation and other authors who decide to use it. You
23
- can use it too, but we suggest you first think carefully about whether
24
- this license or the ordinary General Public License is the better
25
- strategy to use in any particular case, based on the explanations below.
26
-
27
- When we speak of free software, we are referring to freedom of use,
28
- not price. Our General Public Licenses are designed to make sure that
29
- you have the freedom to distribute copies of free software (and charge
30
- for this service if you wish); that you receive source code or can get
31
- it if you want it; that you can change the software and use pieces of
32
- it in new free programs; and that you are informed that you can do
33
- these things.
34
-
35
- To protect your rights, we need to make restrictions that forbid
36
- distributors to deny you these rights or to ask you to surrender these
37
- rights. These restrictions translate to certain responsibilities for
38
- you if you distribute copies of the library or if you modify it.
39
-
40
- For example, if you distribute copies of the library, whether gratis
41
- or for a fee, you must give the recipients all the rights that we gave
42
- you. You must make sure that they, too, receive or can get the source
43
- code. If you link other code with the library, you must provide
44
- complete object files to the recipients, so that they can relink them
45
- with the library after making changes to the library and recompiling
46
- it. And you must show them these terms so they know their rights.
47
-
48
- We protect your rights with a two-step method: (1) we copyright the
49
- library, and (2) we offer you this license, which gives you legal
50
- permission to copy, distribute and/or modify the library.
51
-
52
- To protect each distributor, we want to make it very clear that
53
- there is no warranty for the free library. Also, if the library is
54
- modified by someone else and passed on, the recipients should know
55
- that what they have is not the original version, so that the original
56
- author's reputation will not be affected by problems that might be
57
- introduced by others.
58
-
59
- Finally, software patents pose a constant threat to the existence of
60
- any free program. We wish to make sure that a company cannot
61
- effectively restrict the users of a free program by obtaining a
62
- restrictive license from a patent holder. Therefore, we insist that
63
- any patent license obtained for a version of the library must be
64
- consistent with the full freedom of use specified in this license.
65
-
66
- Most GNU software, including some libraries, is covered by the
67
- ordinary GNU General Public License. This license, the GNU Lesser
68
- General Public License, applies to certain designated libraries, and
69
- is quite different from the ordinary General Public License. We use
70
- this license for certain libraries in order to permit linking those
71
- libraries into non-free programs.
72
-
73
- When a program is linked with a library, whether statically or using
74
- a shared library, the combination of the two is legally speaking a
75
- combined work, a derivative of the original library. The ordinary
76
- General Public License therefore permits such linking only if the
77
- entire combination fits its criteria of freedom. The Lesser General
78
- Public License permits more lax criteria for linking other code with
79
- the library.
80
-
81
- We call this license the "Lesser" General Public License because it
82
- does Less to protect the user's freedom than the ordinary General
83
- Public License. It also provides other free software developers Less
84
- of an advantage over competing non-free programs. These disadvantages
85
- are the reason we use the ordinary General Public License for many
86
- libraries. However, the Lesser license provides advantages in certain
87
- special circumstances.
88
-
89
- For example, on rare occasions, there may be a special need to
90
- encourage the widest possible use of a certain library, so that it becomes
91
- a de-facto standard. To achieve this, non-free programs must be
92
- allowed to use the library. A more frequent case is that a free
93
- library does the same job as widely used non-free libraries. In this
94
- case, there is little to gain by limiting the free library to free
95
- software only, so we use the Lesser General Public License.
96
-
97
- In other cases, permission to use a particular library in non-free
98
- programs enables a greater number of people to use a large body of
99
- free software. For example, permission to use the GNU C Library in
100
- non-free programs enables many more people to use the whole GNU
101
- operating system, as well as its variant, the GNU/Linux operating
102
- system.
103
-
104
- Although the Lesser General Public License is Less protective of the
105
- users' freedom, it does ensure that the user of a program that is
106
- linked with the Library has the freedom and the wherewithal to run
107
- that program using a modified version of the Library.
108
-
109
- The precise terms and conditions for copying, distribution and
110
- modification follow. Pay close attention to the difference between a
111
- "work based on the library" and a "work that uses the library". The
112
- former contains code derived from the library, whereas the latter must
113
- be combined with the library in order to run.
114
-
115
- GNU LESSER GENERAL PUBLIC LICENSE
116
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
117
-
118
- 0. This License Agreement applies to any software library or other
119
- program which contains a notice placed by the copyright holder or
120
- other authorized party saying it may be distributed under the terms of
121
- this Lesser General Public License (also called "this License").
122
- Each licensee is addressed as "you".
123
-
124
- A "library" means a collection of software functions and/or data
125
- prepared so as to be conveniently linked with application programs
126
- (which use some of those functions and data) to form executables.
127
-
128
- The "Library", below, refers to any such software library or work
129
- which has been distributed under these terms. A "work based on the
130
- Library" means either the Library or any derivative work under
131
- copyright law: that is to say, a work containing the Library or a
132
- portion of it, either verbatim or with modifications and/or translated
133
- straightforwardly into another language. (Hereinafter, translation is
134
- included without limitation in the term "modification".)
135
-
136
- "Source code" for a work means the preferred form of the work for
137
- making modifications to it. For a library, complete source code means
138
- all the source code for all modules it contains, plus any associated
139
- interface definition files, plus the scripts used to control compilation
140
- and installation of the library.
141
-
142
- Activities other than copying, distribution and modification are not
143
- covered by this License; they are outside its scope. The act of
144
- running a program using the Library is not restricted, and output from
145
- such a program is covered only if its contents constitute a work based
146
- on the Library (independent of the use of the Library in a tool for
147
- writing it). Whether that is true depends on what the Library does
148
- and what the program that uses the Library does.
149
-
150
- 1. You may copy and distribute verbatim copies of the Library's
151
- complete source code as you receive it, in any medium, provided that
152
- you conspicuously and appropriately publish on each copy an
153
- appropriate copyright notice and disclaimer of warranty; keep intact
154
- all the notices that refer to this License and to the absence of any
155
- warranty; and distribute a copy of this License along with the
156
- Library.
157
-
158
- You may charge a fee for the physical act of transferring a copy,
159
- and you may at your option offer warranty protection in exchange for a
160
- fee.
161
-
162
- 2. You may modify your copy or copies of the Library or any portion
163
- of it, thus forming a work based on the Library, and copy and
164
- distribute such modifications or work under the terms of Section 1
165
- above, provided that you also meet all of these conditions:
166
-
167
- a) The modified work must itself be a software library.
168
-
169
- b) You must cause the files modified to carry prominent notices
170
- stating that you changed the files and the date of any change.
171
-
172
- c) You must cause the whole of the work to be licensed at no
173
- charge to all third parties under the terms of this License.
174
-
175
- d) If a facility in the modified Library refers to a function or a
176
- table of data to be supplied by an application program that uses
177
- the facility, other than as an argument passed when the facility
178
- is invoked, then you must make a good faith effort to ensure that,
179
- in the event an application does not supply such function or
180
- table, the facility still operates, and performs whatever part of
181
- its purpose remains meaningful.
182
-
183
- (For example, a function in a library to compute square roots has
184
- a purpose that is entirely well-defined independent of the
185
- application. Therefore, Subsection 2d requires that any
186
- application-supplied function or table used by this function must
187
- be optional: if the application does not supply it, the square
188
- root function must still compute square roots.)
189
-
190
- These requirements apply to the modified work as a whole. If
191
- identifiable sections of that work are not derived from the Library,
192
- and can be reasonably considered independent and separate works in
193
- themselves, then this License, and its terms, do not apply to those
194
- sections when you distribute them as separate works. But when you
195
- distribute the same sections as part of a whole which is a work based
196
- on the Library, the distribution of the whole must be on the terms of
197
- this License, whose permissions for other licensees extend to the
198
- entire whole, and thus to each and every part regardless of who wrote
199
- it.
200
-
201
- Thus, it is not the intent of this section to claim rights or contest
202
- your rights to work written entirely by you; rather, the intent is to
203
- exercise the right to control the distribution of derivative or
204
- collective works based on the Library.
205
-
206
- In addition, mere aggregation of another work not based on the Library
207
- with the Library (or with a work based on the Library) on a volume of
208
- a storage or distribution medium does not bring the other work under
209
- the scope of this License.
210
-
211
- 3. You may opt to apply the terms of the ordinary GNU General Public
212
- License instead of this License to a given copy of the Library. To do
213
- this, you must alter all the notices that refer to this License, so
214
- that they refer to the ordinary GNU General Public License, version 2,
215
- instead of to this License. (If a newer version than version 2 of the
216
- ordinary GNU General Public License has appeared, then you can specify
217
- that version instead if you wish.) Do not make any other change in
218
- these notices.
219
-
220
- Once this change is made in a given copy, it is irreversible for
221
- that copy, so the ordinary GNU General Public License applies to all
222
- subsequent copies and derivative works made from that copy.
223
-
224
- This option is useful when you wish to copy part of the code of
225
- the Library into a program that is not a library.
226
-
227
- 4. You may copy and distribute the Library (or a portion or
228
- derivative of it, under Section 2) in object code or executable form
229
- under the terms of Sections 1 and 2 above provided that you accompany
230
- it with the complete corresponding machine-readable source code, which
231
- must be distributed under the terms of Sections 1 and 2 above on a
232
- medium customarily used for software interchange.
233
-
234
- If distribution of object code is made by offering access to copy
235
- from a designated place, then offering equivalent access to copy the
236
- source code from the same place satisfies the requirement to
237
- distribute the source code, even though third parties are not
238
- compelled to copy the source along with the object code.
239
-
240
- 5. A program that contains no derivative of any portion of the
241
- Library, but is designed to work with the Library by being compiled or
242
- linked with it, is called a "work that uses the Library". Such a
243
- work, in isolation, is not a derivative work of the Library, and
244
- therefore falls outside the scope of this License.
245
-
246
- However, linking a "work that uses the Library" with the Library
247
- creates an executable that is a derivative of the Library (because it
248
- contains portions of the Library), rather than a "work that uses the
249
- library". The executable is therefore covered by this License.
250
- Section 6 states terms for distribution of such executables.
251
-
252
- When a "work that uses the Library" uses material from a header file
253
- that is part of the Library, the object code for the work may be a
254
- derivative work of the Library even though the source code is not.
255
- Whether this is true is especially significant if the work can be
256
- linked without the Library, or if the work is itself a library. The
257
- threshold for this to be true is not precisely defined by law.
258
-
259
- If such an object file uses only numerical parameters, data
260
- structure layouts and accessors, and small macros and small inline
261
- functions (ten lines or less in length), then the use of the object
262
- file is unrestricted, regardless of whether it is legally a derivative
263
- work. (Executables containing this object code plus portions of the
264
- Library will still fall under Section 6.)
265
-
266
- Otherwise, if the work is a derivative of the Library, you may
267
- distribute the object code for the work under the terms of Section 6.
268
- Any executables containing that work also fall under Section 6,
269
- whether or not they are linked directly with the Library itself.
270
-
271
- 6. As an exception to the Sections above, you may also combine or
272
- link a "work that uses the Library" with the Library to produce a
273
- work containing portions of the Library, and distribute that work
274
- under terms of your choice, provided that the terms permit
275
- modification of the work for the customer's own use and reverse
276
- engineering for debugging such modifications.
277
-
278
- You must give prominent notice with each copy of the work that the
279
- Library is used in it and that the Library and its use are covered by
280
- this License. You must supply a copy of this License. If the work
281
- during execution displays copyright notices, you must include the
282
- copyright notice for the Library among them, as well as a reference
283
- directing the user to the copy of this License. Also, you must do one
284
- of these things:
285
-
286
- a) Accompany the work with the complete corresponding
287
- machine-readable source code for the Library including whatever
288
- changes were used in the work (which must be distributed under
289
- Sections 1 and 2 above); and, if the work is an executable linked
290
- with the Library, with the complete machine-readable "work that
291
- uses the Library", as object code and/or source code, so that the
292
- user can modify the Library and then relink to produce a modified
293
- executable containing the modified Library. (It is understood
294
- that the user who changes the contents of definitions files in the
295
- Library will not necessarily be able to recompile the application
296
- to use the modified definitions.)
297
-
298
- b) Use a suitable shared library mechanism for linking with the
299
- Library. A suitable mechanism is one that (1) uses at run time a
300
- copy of the library already present on the user's computer system,
301
- rather than copying library functions into the executable, and (2)
302
- will operate properly with a modified version of the library, if
303
- the user installs one, as long as the modified version is
304
- interface-compatible with the version that the work was made with.
305
-
306
- c) Accompany the work with a written offer, valid for at
307
- least three years, to give the same user the materials
308
- specified in Subsection 6a, above, for a charge no more
309
- than the cost of performing this distribution.
310
-
311
- d) If distribution of the work is made by offering access to copy
312
- from a designated place, offer equivalent access to copy the above
313
- specified materials from the same place.
314
-
315
- e) Verify that the user has already received a copy of these
316
- materials or that you have already sent this user a copy.
317
-
318
- For an executable, the required form of the "work that uses the
319
- Library" must include any data and utility programs needed for
320
- reproducing the executable from it. However, as a special exception,
321
- the materials to be distributed need not include anything that is
322
- normally distributed (in either source or binary form) with the major
323
- components (compiler, kernel, and so on) of the operating system on
324
- which the executable runs, unless that component itself accompanies
325
- the executable.
326
-
327
- It may happen that this requirement contradicts the license
328
- restrictions of other proprietary libraries that do not normally
329
- accompany the operating system. Such a contradiction means you cannot
330
- use both them and the Library together in an executable that you
331
- distribute.
332
-
333
- 7. You may place library facilities that are a work based on the
334
- Library side-by-side in a single library together with other library
335
- facilities not covered by this License, and distribute such a combined
336
- library, provided that the separate distribution of the work based on
337
- the Library and of the other library facilities is otherwise
338
- permitted, and provided that you do these two things:
339
-
340
- a) Accompany the combined library with a copy of the same work
341
- based on the Library, uncombined with any other library
342
- facilities. This must be distributed under the terms of the
343
- Sections above.
344
-
345
- b) Give prominent notice with the combined library of the fact
346
- that part of it is a work based on the Library, and explaining
347
- where to find the accompanying uncombined form of the same work.
348
-
349
- 8. You may not copy, modify, sublicense, link with, or distribute
350
- the Library except as expressly provided under this License. Any
351
- attempt otherwise to copy, modify, sublicense, link with, or
352
- distribute the Library is void, and will automatically terminate your
353
- rights under this License. However, parties who have received copies,
354
- or rights, from you under this License will not have their licenses
355
- terminated so long as such parties remain in full compliance.
356
-
357
- 9. You are not required to accept this License, since you have not
358
- signed it. However, nothing else grants you permission to modify or
359
- distribute the Library or its derivative works. These actions are
360
- prohibited by law if you do not accept this License. Therefore, by
361
- modifying or distributing the Library (or any work based on the
362
- Library), you indicate your acceptance of this License to do so, and
363
- all its terms and conditions for copying, distributing or modifying
364
- the Library or works based on it.
365
-
366
- 10. Each time you redistribute the Library (or any work based on the
367
- Library), the recipient automatically receives a license from the
368
- original licensor to copy, distribute, link with or modify the Library
369
- subject to these terms and conditions. You may not impose any further
370
- restrictions on the recipients' exercise of the rights granted herein.
371
- You are not responsible for enforcing compliance by third parties with
372
- this License.
373
-
374
- 11. If, as a consequence of a court judgment or allegation of patent
375
- infringement or for any other reason (not limited to patent issues),
376
- conditions are imposed on you (whether by court order, agreement or
377
- otherwise) that contradict the conditions of this License, they do not
378
- excuse you from the conditions of this License. If you cannot
379
- distribute so as to satisfy simultaneously your obligations under this
380
- License and any other pertinent obligations, then as a consequence you
381
- may not distribute the Library at all. For example, if a patent
382
- license would not permit royalty-free redistribution of the Library by
383
- all those who receive copies directly or indirectly through you, then
384
- the only way you could satisfy both it and this License would be to
385
- refrain entirely from distribution of the Library.
386
-
387
- If any portion of this section is held invalid or unenforceable under any
388
- particular circumstance, the balance of the section is intended to apply,
389
- and the section as a whole is intended to apply in other circumstances.
390
-
391
- It is not the purpose of this section to induce you to infringe any
392
- patents or other property right claims or to contest validity of any
393
- such claims; this section has the sole purpose of protecting the
394
- integrity of the free software distribution system which is
395
- implemented by public license practices. Many people have made
396
- generous contributions to the wide range of software distributed
397
- through that system in reliance on consistent application of that
398
- system; it is up to the author/donor to decide if he or she is willing
399
- to distribute software through any other system and a licensee cannot
400
- impose that choice.
401
-
402
- This section is intended to make thoroughly clear what is believed to
403
- be a consequence of the rest of this License.
404
-
405
- 12. If the distribution and/or use of the Library is restricted in
406
- certain countries either by patents or by copyrighted interfaces, the
407
- original copyright holder who places the Library under this License may add
408
- an explicit geographical distribution limitation excluding those countries,
409
- so that distribution is permitted only in or among countries not thus
410
- excluded. In such case, this License incorporates the limitation as if
411
- written in the body of this License.
412
-
413
- 13. The Free Software Foundation may publish revised and/or new
414
- versions of the Lesser General Public License from time to time.
415
- Such new versions will be similar in spirit to the present version,
416
- but may differ in detail to address new problems or concerns.
417
-
418
- Each version is given a distinguishing version number. If the Library
419
- specifies a version number of this License which applies to it and
420
- "any later version", you have the option of following the terms and
421
- conditions either of that version or of any later version published by
422
- the Free Software Foundation. If the Library does not specify a
423
- license version number, you may choose any version ever published by
424
- the Free Software Foundation.
425
-
426
- 14. If you wish to incorporate parts of the Library into other free
427
- programs whose distribution conditions are incompatible with these,
428
- write to the author to ask for permission. For software which is
429
- copyrighted by the Free Software Foundation, write to the Free
430
- Software Foundation; we sometimes make exceptions for this. Our
431
- decision will be guided by the two goals of preserving the free status
432
- of all derivatives of our free software and of promoting the sharing
433
- and reuse of software generally.
434
-
435
- NO WARRANTY
436
-
437
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
438
- WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
439
- EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
440
- OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
441
- KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
442
- IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
443
- PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
444
- LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
445
- THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
446
-
447
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
448
- WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
449
- AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
450
- FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
451
- CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
452
- LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
453
- RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
454
- FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
455
- SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
456
- DAMAGES.
457
-
458
- END OF TERMS AND CONDITIONS
459
-
460
- How to Apply These Terms to Your New Libraries
461
-
462
- If you develop a new library, and you want it to be of the greatest
463
- possible use to the public, we recommend making it free software that
464
- everyone can redistribute and change. You can do so by permitting
465
- redistribution under these terms (or, alternatively, under the terms of the
466
- ordinary General Public License).
467
-
468
- To apply these terms, attach the following notices to the library. It is
469
- safest to attach them to the start of each source file to most effectively
470
- convey the exclusion of warranty; and each file should have at least the
471
- "copyright" line and a pointer to where the full notice is found.
472
-
473
- <one line to give the library's name and a brief idea of what it does.>
474
- Copyright (C) <year> <name of author>
475
-
476
- This library is free software; you can redistribute it and/or
477
- modify it under the terms of the GNU Lesser General Public
478
- License as published by the Free Software Foundation; either
479
- version 2.1 of the License, or (at your option) any later version.
480
-
481
- This library is distributed in the hope that it will be useful,
482
- but WITHOUT ANY WARRANTY; without even the implied warranty of
483
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
484
- Lesser General Public License for more details.
485
-
486
- You should have received a copy of the GNU Lesser General Public
487
- License along with this library; if not, write to the Free Software
488
- Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
489
-
490
- Also add information on how to contact you by electronic and paper mail.
491
-
492
- You should also get your employer (if you work as a programmer) or your
493
- school, if any, to sign a "copyright disclaimer" for the library, if
494
- necessary. Here is a sample; alter the names:
495
-
496
- Yoyodyne, Inc., hereby disclaims all copyright interest in the
497
