7 Ryan (icculus@clutteredmind.org), and we can discuss an alternate license for
8 money to be distributed between the contributors to this work, but I'd
9 encourage you to abide by the LGPL, since the usual concern is whether you
10 can use this library without releasing your own source code (you can).

17 Version 2.1, February 1999

20 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
21 Everyone is permitted to copy and distribute verbatim copies
22 of this license document, but changing it is not allowed.
23
24 [This is the first released version of the Lesser GPL. It also counts
25 as the successor of the GNU Library Public License, version 2, hence
26 the version number 2.1.]
27
28 Preamble
29
30 The licenses for most software are designed to take away your
31 freedom to share and change it. By contrast, the GNU General Public
32 Licenses are intended to guarantee your freedom to share and change
33 free software--to make sure the software is free for all its users.
34
35 This license, the Lesser General Public License, applies to some
36 specially designated software packages--typically libraries--of the
37 Free Software Foundation and other authors who decide to use it. You
38 can use it too, but we suggest you first think carefully about whether
39 this license or the ordinary General Public License is the better
40 strategy to use in any particular case, based on the explanations below.
41
42 When we speak of free software, we are referring to freedom of use,
43 not price. Our General Public Licenses are designed to make sure that
44 you have the freedom to distribute copies of free software (and charge
45 for this service if you wish); that you receive source code or can get
46 it if you want it; that you can change the software and use pieces of
47 it in new free programs; and that you are informed that you can do
48 these things.
49
50 To protect your rights, we need to make restrictions that forbid
51 distributors to deny you these rights or to ask you to surrender these
52 rights. These restrictions translate to certain responsibilities for
53 you if you distribute copies of the library or if you modify it.
54
55 For example, if you distribute copies of the library, whether gratis
56 or for a fee, you must give the recipients all the rights that we gave
57 you. You must make sure that they, too, receive or can get the source
58 code. If you link other code with the library, you must provide
59 complete object files to the recipients, so that they can relink them
60 with the library after making changes to the library and recompiling
61 it. And you must show them these terms so they know their rights.
62
63 We protect your rights with a two-step method: (1) we copyright the
64 library, and (2) we offer you this license, which gives you legal
65 permission to copy, distribute and/or modify the library.
66
67 To protect each distributor, we want to make it very clear that
68 there is no warranty for the free library. Also, if the library is
69 modified by someone else and passed on, the recipients should know
70 that what they have is not the original version, so that the original
71 author's reputation will not be affected by problems that might be
72 introduced by others.
73
74 Finally, software patents pose a constant threat to the existence of
75 any free program. We wish to make sure that a company cannot
76 effectively restrict the users of a free program by obtaining a
77 restrictive license from a patent holder. Therefore, we insist that
78 any patent license obtained for a version of the library must be
79 consistent with the full freedom of use specified in this license.
80
81 Most GNU software, including some libraries, is covered by the
82 ordinary GNU General Public License. This license, the GNU Lesser
83 General Public License, applies to certain designated libraries, and
84 is quite different from the ordinary General Public License. We use
85 this license for certain libraries in order to permit linking those
86 libraries into non-free programs.
87
88 When a program is linked with a library, whether statically or using
89 a shared library, the combination of the two is legally speaking a
90 combined work, a derivative of the original library. The ordinary
91 General Public License therefore permits such linking only if the
92 entire combination fits its criteria of freedom. The Lesser General
93 Public License permits more lax criteria for linking other code with
94 the library.
95
96 We call this license the "Lesser" General Public License because it
97 does Less to protect the user's freedom than the ordinary General
98 Public License. It also provides other free software developers Less
99 of an advantage over competing non-free programs. These disadvantages
100 are the reason we use the ordinary General Public License for many
101 libraries. However, the Lesser license provides advantages in certain
102 special circumstances.
103
104 For example, on rare occasions, there may be a special need to
105 encourage the widest possible use of a certain library, so that it becomes
106 a de-facto standard. To achieve this, non-free programs must be
107 allowed to use the library. A more frequent case is that a free
108 library does the same job as widely used non-free libraries. In this
109 case, there is little to gain by limiting the free library to free
110 software only, so we use the Lesser General Public License.
111
112 In other cases, permission to use a particular library in non-free
113 programs enables a greater number of people to use a large body of
114 free software. For example, permission to use the GNU C Library in
115 non-free programs enables many more people to use the whole GNU
116 operating system, as well as its variant, the GNU/Linux operating
117 system.
118
119 Although the Lesser General Public License is Less protective of the
120 users' freedom, it does ensure that the user of a program that is
121 linked with the Library has the freedom and the wherewithal to run
122 that program using a modified version of the Library.
123
124 The precise terms and conditions for copying, distribution and
125 modification follow. Pay close attention to the difference between a
126 "work based on the library" and a "work that uses the library". The
127 former contains code derived from the library, whereas the latter must
128 be combined with the library in order to run.
129
130 GNU LESSER GENERAL PUBLIC LICENSE
131 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
132
133 0. This License Agreement applies to any software library or other
134 program which contains a notice placed by the copyright holder or
135 other authorized party saying it may be distributed under the terms of
136 this Lesser General Public License (also called "this License").
137 Each licensee is addressed as "you".
138
139 A "library" means a collection of software functions and/or data
140 prepared so as to be conveniently linked with application programs
141 (which use some of those functions and data) to form executables.
142
143 The "Library", below, refers to any such software library or work
144 which has been distributed under these terms. A "work based on the
145 Library" means either the Library or any derivative work under
146 copyright law: that is to say, a work containing the Library or a
147 portion of it, either verbatim or with modifications and/or translated
148 straightforwardly into another language. (Hereinafter, translation is
149 included without limitation in the term "modification".)
150
151 "Source code" for a work means the preferred form of the work for
152 making modifications to it. For a library, complete source code means
153 all the source code for all modules it contains, plus any associated
154 interface definition files, plus the scripts used to control compilation
155 and installation of the library.
156
157 Activities other than copying, distribution and modification are not
158 covered by this License; they are outside its scope. The act of
159 running a program using the Library is not restricted, and output from
160 such a program is covered only if its contents constitute a work based
161 on the Library (independent of the use of the Library in a tool for
162 writing it). Whether that is true depends on what the Library does
163 and what the program that uses the Library does.
164
165 1. You may copy and distribute verbatim copies of the Library's
166 complete source code as you receive it, in any medium, provided that
167 you conspicuously and appropriately publish on each copy an
168 appropriate copyright notice and disclaimer of warranty; keep intact
169 all the notices that refer to this License and to the absence of any
170 warranty; and distribute a copy of this License along with the
171 Library.
172
173 You may charge a fee for the physical act of transferring a copy,
174 and you may at your option offer warranty protection in exchange for a
175 fee.
176
177 2. You may modify your copy or copies of the Library or any portion
178 of it, thus forming a work based on the Library, and copy and
179 distribute such modifications or work under the terms of Section 1
180 above, provided that you also meet all of these conditions:
181
182 a) The modified work must itself be a software library.
183
184 b) You must cause the files modified to carry prominent notices
185 stating that you changed the files and the date of any change.
186
187 c) You must cause the whole of the work to be licensed at no
188 charge to all third parties under the terms of this License.
189
190 d) If a facility in the modified Library refers to a function or a
191 table of data to be supplied by an application program that uses
192 the facility, other than as an argument passed when the facility
193 is invoked, then you must make a good faith effort to ensure that,
194 in the event an application does not supply such function or
195 table, the facility still operates, and performs whatever part of
196 its purpose remains meaningful.
197
198 (For example, a function in a library to compute square roots has
199 a purpose that is entirely well-defined independent of the
200 application. Therefore, Subsection 2d requires that any
201 application-supplied function or table used by this function must
202 be optional: if the application does not supply it, the square
203 root function must still compute square roots.)
204
205 These requirements apply to the modified work as a whole. If
206 identifiable sections of that work are not derived from the Library,
207 and can be reasonably considered independent and separate works in
208 themselves, then this License, and its terms, do not apply to those
209 sections when you distribute them as separate works. But when you
210 distribute the same sections as part of a whole which is a work based
211 on the Library, the distribution of the whole must be on the terms of
212 this License, whose permissions for other licensees extend to the
213 entire whole, and thus to each and every part regardless of who wrote
214 it.
215
216 Thus, it is not the intent of this section to claim rights or contest
217 your rights to work written entirely by you; rather, the intent is to
218 exercise the right to control the distribution of derivative or
219 collective works based on the Library.
220
221 In addition, mere aggregation of another work not based on the Library
222 with the Library (or with a work based on the Library) on a volume of
223 a storage or distribution medium does not bring the other work under
224 the scope of this License.
225
226 3. You may opt to apply the terms of the ordinary GNU General Public
227 License instead of this License to a given copy of the Library. To do
228 this, you must alter all the notices that refer to this License, so
229 that they refer to the ordinary GNU General Public License, version 2,
230 instead of to this License. (If a newer version than version 2 of the
231 ordinary GNU General Public License has appeared, then you can specify
232 that version instead if you wish.) Do not make any other change in
233 these notices.
234
235 Once this change is made in a given copy, it is irreversible for
236 that copy, so the ordinary GNU General Public License applies to all
237 subsequent copies and derivative works made from that copy.
238
239 This option is useful when you wish to copy part of the code of
240 the Library into a program that is not a library.
241
242 4. You may copy and distribute the Library (or a portion or
243 derivative of it, under Section 2) in object code or executable form
244 under the terms of Sections 1 and 2 above provided that you accompany
245 it with the complete corresponding machine-readable source code, which
246 must be distributed under the terms of Sections 1 and 2 above on a
247 medium customarily used for software interchange.
248
249 If distribution of object code is made by offering access to copy
250 from a designated place, then offering equivalent access to copy the
251 source code from the same place satisfies the requirement to
252 distribute the source code, even though third parties are not
253 compelled to copy the source along with the object code.
254
255 5. A program that contains no derivative of any portion of the
256 Library, but is designed to work with the Library by being compiled or
257 linked with it, is called a "work that uses the Library". Such a
258 work, in isolation, is not a derivative work of the Library, and
259 therefore falls outside the scope of this License.
260
261 However, linking a "work that uses the Library" with the Library
262 creates an executable that is a derivative of the Library (because it
263 contains portions of the Library), rather than a "work that uses the
264 library". The executable is therefore covered by this License.
265 Section 6 states terms for distribution of such executables.
266
267 When a "work that uses the Library" uses material from a header file
268 that is part of the Library, the object code for the work may be a
269 derivative work of the Library even though the source code is not.
270 Whether this is true is especially significant if the work can be
271 linked without the Library, or if the work is itself a library. The
272 threshold for this to be true is not precisely defined by law.
273
274 If such an object file uses only numerical parameters, data
275 structure layouts and accessors, and small macros and small inline
276 functions (ten lines or less in length), then the use of the object
277 file is unrestricted, regardless of whether it is legally a derivative
278 work. (Executables containing this object code plus portions of the
279 Library will still fall under Section 6.)
280
281 Otherwise, if the work is a derivative of the Library, you may
282 distribute the object code for the work under the terms of Section 6.
283 Any executables containing that work also fall under Section 6,
284 whether or not they are linked directly with the Library itself.
285
286 6. As an exception to the Sections above, you may also combine or
287 link a "work that uses the Library" with the Library to produce a
288 work containing portions of the Library, and distribute that work
289 under terms of your choice, provided that the terms permit
290 modification of the work for the customer's own use and reverse
291 engineering for debugging such modifications.
292
293 You must give prominent notice with each copy of the work that the
294 Library is used in it and that the Library and its use are covered by
295 this License. You must supply a copy of this License. If the work
296 during execution displays copyright notices, you must include the
297 copyright notice for the Library among them, as well as a reference
298 directing the user to the copy of this License. Also, you must do one
299 of these things:
300
301 a) Accompany the work with the complete corresponding
302 machine-readable source code for the Library including whatever
303 changes were used in the work (which must be distributed under
304 Sections 1 and 2 above); and, if the work is an executable linked
305 with the Library, with the complete machine-readable "work that
306 uses the Library", as object code and/or source code, so that the
307 user can modify the Library and then relink to produce a modified
308 executable containing the modified Library. (It is understood
309 that the user who changes the contents of definitions files in the
310 Library will not necessarily be able to recompile the application
311 to use the modified definitions.)
312
313 b) Use a suitable shared library mechanism for linking with the
314 Library. A suitable mechanism is one that (1) uses at run time a
315 copy of the library already present on the user's computer system,
316 rather than copying library functions into the executable, and (2)
317 will operate properly with a modified version of the library, if
318 the user installs one, as long as the modified version is
319 interface-compatible with the version that the work was made with.
320
321 c) Accompany the work with a written offer, valid for at
322 least three years, to give the same user the materials
323 specified in Subsection 6a, above, for a charge no more
324 than the cost of performing this distribution.
325
326 d) If distribution of the work is made by offering access to copy
327 from a designated place, offer equivalent access to copy the above
328 specified materials from the same place.
329
330 e) Verify that the user has already received a copy of these
331 materials or that you have already sent this user a copy.
332
333 For an executable, the required form of the "work that uses the
334 Library" must include any data and utility programs needed for
335 reproducing the executable from it. However, as a special exception,
336 the materials to be distributed need not include anything that is
337 normally distributed (in either source or binary form) with the major
338 components (compiler, kernel, and so on) of the operating system on
339 which the executable runs, unless that component itself accompanies
340 the executable.
341
342 It may happen that this requirement contradicts the license
343 restrictions of other proprietary libraries that do not normally
344 accompany the operating system. Such a contradiction means you cannot
345 use both them and the Library together in an executable that you
346 distribute.
347
348 7. You may place library facilities that are a work based on the
349 Library side-by-side in a single library together with other library
350 facilities not covered by this License, and distribute such a combined
351 library, provided that the separate distribution of the work based on
352 the Library and of the other library facilities is otherwise
353 permitted, and provided that you do these two things:
354
355 a) Accompany the combined library with a copy of the same work
356 based on the Library, uncombined with any other library
357 facilities. This must be distributed under the terms of the
358 Sections above.
359
360 b) Give prominent notice with the combined library of the fact
361 that part of it is a work based on the Library, and explaining
362 where to find the accompanying uncombined form of the same work.
363
364 8. You may not copy, modify, sublicense, link with, or distribute
365 the Library except as expressly provided under this License. Any
366 attempt otherwise to copy, modify, sublicense, link with, or
367 distribute the Library is void, and will automatically terminate your
368 rights under this License. However, parties who have received copies,
369 or rights, from you under this License will not have their licenses
370 terminated so long as such parties remain in full compliance.
371
372 9. You are not required to accept this License, since you have not
373 signed it. However, nothing else grants you permission to modify or
374 distribute the Library or its derivative works. These actions are
375 prohibited by law if you do not accept this License. Therefore, by
376 modifying or distributing the Library (or any work based on the
377 Library), you indicate your acceptance of this License to do so, and
378 all its terms and conditions for copying, distributing or modifying
379 the Library or works based on it.
380
381 10. Each time you redistribute the Library (or any work based on the
382 Library), the recipient automatically receives a license from the
383 original licensor to copy, distribute, link with or modify the Library
384 subject to these terms and conditions. You may not impose any further
385 restrictions on the recipients' exercise of the rights granted herein.
386 You are not responsible for enforcing compliance by third parties with
387 this License.
388
389 11. If, as a consequence of a court judgment or allegation of patent
390 infringement or for any other reason (not limited to patent issues),
391 conditions are imposed on you (whether by court order, agreement or
392 otherwise) that contradict the conditions of this License, they do not
393 excuse you from the conditions of this License. If you cannot
394 distribute so as to satisfy simultaneously your obligations under this
395 License and any other pertinent obligations, then as a consequence you
396 may not distribute the Library at all. For example, if a patent
397 license would not permit royalty-free redistribution of the Library by
398 all those who receive copies directly or indirectly through you, then
399 the only way you could satisfy both it and this License would be to
400 refrain entirely from distribution of the Library.
401
402 If any portion of this section is held invalid or unenforceable under any
403 particular circumstance, the balance of the section is intended to apply,
404 and the section as a whole is intended to apply in other circumstances.
405
406 It is not the purpose of this section to induce you to infringe any
407 patents or other property right claims or to contest validity of any
408 such claims; this section has the sole purpose of protecting the
409 integrity of the free software distribution system which is
410 implemented by public license practices. Many people have made
411 generous contributions to the wide range of software distributed
412 through that system in reliance on consistent application of that
413 system; it is up to the author/donor to decide if he or she is willing
414 to distribute software through any other system and a licensee cannot
415 impose that choice.
416
417 This section is intended to make thoroughly clear what is believed to
418 be a consequence of the rest of this License.
419
420 12. If the distribution and/or use of the Library is restricted in
421 certain countries either by patents or by copyrighted interfaces, the
422 original copyright holder who places the Library under this License may add
423 an explicit geographical distribution limitation excluding those countries,
424 so that distribution is permitted only in or among countries not thus
425 excluded. In such case, this License incorporates the limitation as if
426 written in the body of this License.
427
428 13. The Free Software Foundation may publish revised and/or new
429 versions of the Lesser General Public License from time to time.
430 Such new versions will be similar in spirit to the present version,
431 but may differ in detail to address new problems or concerns.
432
433 Each version is given a distinguishing version number. If the Library
434 specifies a version number of this License which applies to it and
435 "any later version", you have the option of following the terms and
436 conditions either of that version or of any later version published by
437 the Free Software Foundation. If the Library does not specify a
438 license version number, you may choose any version ever published by
439 the Free Software Foundation.
440
441 14. If you wish to incorporate parts of the Library into other free
442 programs whose distribution conditions are incompatible with these,
443 write to the author to ask for permission. For software which is
444 copyrighted by the Free Software Foundation, write to the Free
445 Software Foundation; we sometimes make exceptions for this. Our
446 decision will be guided by the two goals of preserving the free status
447 of all derivatives of our free software and of promoting the sharing
448 and reuse of software generally.
449
450 NO WARRANTY
451
452 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
453 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
454 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
455 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
456 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
457 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
458 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
459 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
460 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
461
462 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
463 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
464 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
465 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
466 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
467 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
468 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
469 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
470 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
471 DAMAGES.
472
473 END OF TERMS AND CONDITIONS
474
475 How to Apply These Terms to Your New Libraries
476
477 If you develop a new library, and you want it to be of the greatest
478 possible use to the public, we recommend making it free software that
479 everyone can redistribute and change. You can do so by permitting
480 redistribution under these terms (or, alternatively, under the terms of the
481 ordinary General Public License).
482
483 To apply these terms, attach the following notices to the library. It is
484 safest to attach them to the start of each source file to most effectively
485 convey the exclusion of warranty; and each file should have at least the
486 "copyright" line and a pointer to where the full notice is found.
487
488 <one line to give the library's name and a brief idea of what it does.>
489 Copyright (C) <year> <name of author>
490
491 This library is free software; you can redistribute it and/or
492 modify it under the terms of the GNU Lesser General Public
493 License as published by the Free Software Foundation; either
494 version 2.1 of the License, or (at your option) any later version.
495
496 This library is distributed in the hope that it will be useful,
497 but WITHOUT ANY WARRANTY; without even the implied warranty of
498 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
499 Lesser General Public License for more details.
500
