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

20 [This is the first released version of the Lesser GPL. It also counts
21 as the successor of the GNU Library Public License, version 2, hence the
22 version number 2.1.]

27 <H3>Preamble</H3>
28
29 <P>
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
36 <P>
37 This license, the Lesser General Public License, applies to some
38 specially designated software--typically libraries--of the Free
39 Software Foundation and other authors who decide to use it. You can use
40 it too, but we suggest you first think carefully about whether this
41 license or the ordinary General Public License is the better strategy to
42 use in any particular case, based on the explanations below.
43
44
45 <P>
46 When we speak of free software, we are referring to freedom of use,
47 not price. Our General Public Licenses are designed to make sure that
48 you have the freedom to distribute copies of free software (and charge
49 for this service if you wish); that you receive source code or can get
50 it if you want it; that you can change the software and use pieces of it
51 in new free programs; and that you are informed that you can do these
52 things.
53
54
55 <P>
56 To protect your rights, we need to make restrictions that forbid
57 distributors to deny you these rights or to ask you to surrender these
58 rights. These restrictions translate to certain responsibilities for
59 you if you distribute copies of the library or if you modify it.
60
61
62 <P>
63 For example, if you distribute copies of the library, whether gratis
64 or for a fee, you must give the recipients all the rights that we gave
65 you. You must make sure that they, too, receive or can get the source
66 code. If you link other code with the library, you must provide
67 complete object files to the recipients, so that they can relink them
68 with the library after making changes to the library and recompiling
69 it. And you must show them these terms so they know their rights.
70
71
72 <P>
73 We protect your rights with a two-step method: (1) we copyright the
74 library, and (2) we offer you this license, which gives you legal
75 permission to copy, distribute and/or modify the library.
76
77
78 <P>
79 To protect each distributor, we want to make it very clear that
80 there is no warranty for the free library. Also, if the library is
81 modified by someone else and passed on, the recipients should know
82 that what they have is not the original version, so that the original
83 author's reputation will not be affected by problems that might be
84 introduced by others.
85
86
87 <P>
88 Finally, software patents pose a constant threat to the existence of
89 any free program. We wish to make sure that a company cannot
90 effectively restrict the users of a free program by obtaining a
91 restrictive license from a patent holder. Therefore, we insist that
92 any patent license obtained for a version of the library must be
93 consistent with the full freedom of use specified in this license.
94
95
96 <P>
97 Most GNU software, including some libraries, is covered by the
98 ordinary GNU General Public License. This license, the GNU Lesser
99 General Public License, applies to certain designated libraries, and
100 is quite different from the ordinary General Public License. We use
101 this license for certain libraries in order to permit linking those
102 libraries into non-free programs.
103
104
105 <P>
106 When a program is linked with a library, whether statically or using
107 a shared library, the combination of the two is legally speaking a
108 combined work, a derivative of the original library. The ordinary
109 General Public License therefore permits such linking only if the
110 entire combination fits its criteria of freedom. The Lesser General
111 Public License permits more lax criteria for linking other code with
112 the library.
113
114
115 <P>
116 We call this license the <EM>Lesser</EM> General Public License because it
117 does <EM>Less</EM> to protect the user's freedom than the ordinary General
118 Public License. It also provides other free software developers Less
119 of an advantage over competing non-free programs. These disadvantages
120 are the reason we use the ordinary General Public License for many
121 libraries. However, the Lesser license provides advantages in certain
122 special circumstances.
123
124
125 <P>
126 For example, on rare occasions, there may be a special need to
127 encourage the widest possible use of a certain library, so that it becomes
128 a de-facto standard. To achieve this, non-free programs must be
129 allowed to use the library. A more frequent case is that a free
130 library does the same job as widely used non-free libraries. In this
131 case, there is little to gain by limiting the free library to free
132 software only, so we use the Lesser General Public License.
133
134
135 <P>
136 In other cases, permission to use a particular library in non-free
137 programs enables a greater number of people to use a large body of
138 free software. For example, permission to use the GNU C Library in
139 non-free programs enables many more people to use the whole GNU
140 operating system, as well as its variant, the GNU/Linux operating
141 system.
142
143
144 <P>
145 Although the Lesser General Public License is Less protective of the
146 users' freedom, it does ensure that the user of a program that is
147 linked with the Library has the freedom and the wherewithal to run
148 that program using a modified version of the Library.
149
150
151 <P>
152 The precise terms and conditions for copying, distribution and
153 modification follow. Pay close attention to the difference between a
154 "work based on the library" and a "work that uses the library". The
155 former contains code derived from the library, whereas the latter must
156 be combined with the library in order to run.
157
158
159
160
161 <H3>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</H3>
162
163
164 <OL>
165 <LI>
166
167 This License Agreement applies to any software library or other program
168 which contains a notice placed by the copyright holder or other
169 authorized party saying it may be distributed under the terms of this
170 Lesser General Public License (also called "this License"). Each
171 licensee is addressed as "you".
172
173 A "library" means a collection of software functions and/or data
174 prepared so as to be conveniently linked with application programs
175 (which use some of those functions and data) to form executables.
176
177 The "Library", below, refers to any such software library or work
178 which has been distributed under these terms. A "work based on the
179 Library" means either the Library or any derivative work under
180 copyright law: that is to say, a work containing the Library or a
181 portion of it, either verbatim or with modifications and/or translated
182 straightforwardly into another language. (Hereinafter, translation is
183 included without limitation in the term "modification".)
184
185 "Source code" for a work means the preferred form of the work for
186 making modifications to it. For a library, complete source code means
187 all the source code for all modules it contains, plus any associated
188 interface definition files, plus the scripts used to control compilation
189 and installation of the library.
190
191 Activities other than copying, distribution and modification are not
192 covered by this License; they are outside its scope. The act of
193 running a program using the Library is not restricted, and output from
194 such a program is covered only if its contents constitute a work based
195 on the Library (independent of the use of the Library in a tool for
196 writing it). Whether that is true depends on what the Library does
197 and what the program that uses the Library does.
198
199 <LI>
200
201 You may copy and distribute verbatim copies of the Library's
202 complete source code as you receive it, in any medium, provided that
203 you conspicuously and appropriately publish on each copy an
204 appropriate copyright notice and disclaimer of warranty; keep intact
205 all the notices that refer to this License and to the absence of any
206 warranty; and distribute a copy of this License along with the
207 Library.
208
209 You may charge a fee for the physical act of transferring a copy,
210 and you may at your option offer warranty protection in exchange for a
211 fee.
212
213 <LI>
214
215 You may modify your copy or copies of the Library or any portion
216 of it, thus forming a work based on the Library, and copy and
217 distribute such modifications or work under the terms of Section 1
218 above, provided that you also meet all of these conditions:
219
220
221 <OL>
222 <LI>
223
224 The modified work must itself be a software library.
225
226 <LI>
227
228 You must cause the files modified to carry prominent notices
229 stating that you changed the files and the date of any change.
230
231 <LI>
232
233 You must cause the whole of the work to be licensed at no
234 charge to all third parties under the terms of this License.
235
236 <LI>
237
238 If a facility in the modified Library refers to a function or a
239 table of data to be supplied by an application program that uses
240 the facility, other than as an argument passed when the facility
241 is invoked, then you must make a good faith effort to ensure that,
242 in the event an application does not supply such function or
243 table, the facility still operates, and performs whatever part of
244 its purpose remains meaningful.
245
246 (For example, a function in a library to compute square roots has
247 a purpose that is entirely well-defined independent of the
248 application. Therefore, Subsection 2d requires that any
249 application-supplied function or table used by this function must
250 be optional: if the application does not supply it, the square
251 root function must still compute square roots.)
252 </OL>
253
254 These requirements apply to the modified work as a whole. If
255 identifiable sections of that work are not derived from the Library,
256 and can be reasonably considered independent and separate works in
257 themselves, then this License, and its terms, do not apply to those
258 sections when you distribute them as separate works. But when you
259 distribute the same sections as part of a whole which is a work based
260 on the Library, the distribution of the whole must be on the terms of
261 this License, whose permissions for other licensees extend to the
262 entire whole, and thus to each and every part regardless of who wrote
263 it.
264
265 Thus, it is not the intent of this section to claim rights or contest
266 your rights to work written entirely by you; rather, the intent is to
267 exercise the right to control the distribution of derivative or
268 collective works based on the Library.
269
270 In addition, mere aggregation of another work not based on the Library
271 with the Library (or with a work based on the Library) on a volume of
272 a storage or distribution medium does not bring the other work under
273 the scope of this License.
274
275 <LI>
276
277 You may opt to apply the terms of the ordinary GNU General Public
278 License instead of this License to a given copy of the Library. To do
279 this, you must alter all the notices that refer to this License, so
280 that they refer to the ordinary GNU General Public License, version 2,
281 instead of to this License. (If a newer version than version 2 of the
282 ordinary GNU General Public License has appeared, then you can specify
283 that version instead if you wish.) Do not make any other change in
284 these notices.
285
286 Once this change is made in a given copy, it is irreversible for
287 that copy, so the ordinary GNU General Public License applies to all
288 subsequent copies and derivative works made from that copy.
289
290 This option is useful when you wish to copy part of the code of
291 the Library into a program that is not a library.
292
293 <LI>
294
295 You may copy and distribute the Library (or a portion or
296 derivative of it, under Section 2) in object code or executable form
297 under the terms of Sections 1 and 2 above provided that you accompany
298 it with the complete corresponding machine-readable source code, which
299 must be distributed under the terms of Sections 1 and 2 above on a
300 medium customarily used for software interchange.
301
302 If distribution of object code is made by offering access to copy
303 from a designated place, then offering equivalent access to copy the
304 source code from the same place satisfies the requirement to
305 distribute the source code, even though third parties are not
306 compelled to copy the source along with the object code.
307
308 <LI>
309
310 A program that contains no derivative of any portion of the
311 Library, but is designed to work with the Library by being compiled or
312 linked with it, is called a "work that uses the Library". Such a
313 work, in isolation, is not a derivative work of the Library, and
314 therefore falls outside the scope of this License.
315
316 However, linking a "work that uses the Library" with the Library
317 creates an executable that is a derivative of the Library (because it
318 contains portions of the Library), rather than a "work that uses the
319 library". The executable is therefore covered by this License.
320 Section 6 states terms for distribution of such executables.
321
322 When a "work that uses the Library" uses material from a header file
323 that is part of the Library, the object code for the work may be a
324 derivative work of the Library even though the source code is not.
325 Whether this is true is especially significant if the work can be
326 linked without the Library, or if the work is itself a library. The
327 threshold for this to be true is not precisely defined by law.
328
329 If such an object file uses only numerical parameters, data
330 structure layouts and accessors, and small macros and small inline
331 functions (ten lines or less in length), then the use of the object
332 file is unrestricted, regardless of whether it is legally a derivative
333 work. (Executables containing this object code plus portions of the
334 Library will still fall under Section 6.)
335
336 Otherwise, if the work is a derivative of the Library, you may
337 distribute the object code for the work under the terms of Section 6.
338 Any executables containing that work also fall under Section 6,
339 whether or not they are linked directly with the Library itself.
340
341 <LI>
342
343 As an exception to the Sections above, you may also combine or
344 link a "work that uses the Library" with the Library to produce a
345 work containing portions of the Library, and distribute that work
346 under terms of your choice, provided that the terms permit
347 modification of the work for the customer's own use and reverse
348 engineering for debugging such modifications.
349
350 You must give prominent notice with each copy of the work that the
351 Library is used in it and that the Library and its use are covered by
352 this License. You must supply a copy of this License. If the work
353 during execution displays copyright notices, you must include the
354 copyright notice for the Library among them, as well as a reference
355 directing the user to the copy of this License. Also, you must do one
356 of these things:
357
358
359 <OL>
360 <LI>
361
362 Accompany the work with the complete corresponding
363 machine-readable source code for the Library including whatever
364 changes were used in the work (which must be distributed under
365 Sections 1 and 2 above); and, if the work is an executable linked
366 with the Library, with the complete machine-readable "work that
367 uses the Library", as object code and/or source code, so that the
368 user can modify the Library and then relink to produce a modified
369 executable containing the modified Library. (It is understood
370 that the user who changes the contents of definitions files in the
371 Library will not necessarily be able to recompile the application
372 to use the modified definitions.)
373
374 <LI>
375
376 Use a suitable shared library mechanism for linking with the Library. A
377 suitable mechanism is one that (1) uses at run time a copy of the
378 library already present on the user's computer system, rather than
379 copying library functions into the executable, and (2) will operate
380 properly with a modified version of the library, if the user installs
381 one, as long as the modified version is interface-compatible with the
382 version that the work was made with.
383
384 <LI>
385
386 Accompany the work with a written offer, valid for at
387 least three years, to give the same user the materials
388 specified in Subsection 6a, above, for a charge no more
389 than the cost of performing this distribution.
390
391 <LI>
392
393 If distribution of the work is made by offering access to copy
394 from a designated place, offer equivalent access to copy the above
395 specified materials from the same place.
396
397 <LI>
398
399 Verify that the user has already received a copy of these
400 materials or that you have already sent this user a copy.
401 </OL>
402
403 For an executable, the required form of the "work that uses the
404 Library" must include any data and utility programs needed for
405 reproducing the executable from it. However, as a special exception,
406 the materials to be distributed need not include anything that is
407 normally distributed (in either source or binary form) with the major
408 components (compiler, kernel, and so on) of the operating system on
409 which the executable runs, unless that component itself accompanies the
410 executable.
411
412 It may happen that this requirement contradicts the license
413 restrictions of other proprietary libraries that do not normally
414 accompany the operating system. Such a contradiction means you cannot
415 use both them and the Library together in an executable that you
416 distribute.
417
418 <LI>
419
420 You may place library facilities that are a work based on the
421 Library side-by-side in a single library together with other library
422 facilities not covered by this License, and distribute such a combined
423 library, provided that the separate distribution of the work based on
424 the Library and of the other library facilities is otherwise
425 permitted, and provided that you do these two things:
426
427
428 <OL>
429 <LI>
430
431 Accompany the combined library with a copy of the same work
432 based on the Library, uncombined with any other library
433 facilities. This must be distributed under the terms of the
434 Sections above.
435
436 <LI>
437
438 Give prominent notice with the combined library of the fact
439 that part of it is a work based on the Library, and explaining
440 where to find the accompanying uncombined form of the same work.
441 </OL>
442
443 <LI>
444
445 You may not copy, modify, sublicense, link with, or distribute
446 the Library except as expressly provided under this License. Any
447 attempt otherwise to copy, modify, sublicense, link with, or
448 distribute the Library is void, and will automatically terminate your
449 rights under this License. However, parties who have received copies,
450 or rights, from you under this License will not have their licenses
451 terminated so long as such parties remain in full compliance.
452
453 <LI>
454
455 You are not required to accept this License, since you have not
456 signed it. However, nothing else grants you permission to modify or
457 distribute the Library or its derivative works. These actions are
458 prohibited by law if you do not accept this License. Therefore, by
459 modifying or distributing the Library (or any work based on the
460 Library), you indicate your acceptance of this License to do so, and
461 all its terms and conditions for copying, distributing or modifying
462 the Library or works based on it.
463
464 <LI>
465
466 Each time you redistribute the Library (or any work based on the
467 Library), the recipient automatically receives a license from the
468 original licensor to copy, distribute, link with or modify the Library
469 subject to these terms and conditions. You may not impose any further
470 restrictions on the recipients' exercise of the rights granted herein.
471 You are not responsible for enforcing compliance by third parties with
472 this License.
473
474 <LI>
475
476 If, as a consequence of a court judgment or allegation of patent
477 infringement or for any other reason (not limited to patent issues),
478 conditions are imposed on you (whether by court order, agreement or
479 otherwise) that contradict the conditions of this License, they do not
480 excuse you from the conditions of this License. If you cannot
481 distribute so as to satisfy simultaneously your obligations under this
482 License and any other pertinent obligations, then as a consequence you
483 may not distribute the Library at all. For example, if a patent
484 license would not permit royalty-free redistribution of the Library by
485 all those who receive copies directly or indirectly through you, then
486 the only way you could satisfy both it and this License would be to
487 refrain entirely from distribution of the Library.
488
489 If any portion of this section is held invalid or unenforceable under any
490 particular circumstance, the balance of the section is intended to apply,
491 and the section as a whole is intended to apply in other circumstances.
492
493 It is not the purpose of this section to induce you to infringe any
494 patents or other property right claims or to contest validity of any
495 such claims; this section has the sole purpose of protecting the
496 integrity of the free software distribution system which is
497 implemented by public license practices. Many people have made
498 generous contributions to the wide range of software distributed
499 through that system in reliance on consistent application of that
500 system; it is up to the author/donor to decide if he or she is willing
501 to distribute software through any other system and a licensee cannot
502 impose that choice.
503
504 This section is intended to make thoroughly clear what is believed to
505 be a consequence of the rest of this License.
506
507 <LI>
508
509 If the distribution and/or use of the Library is restricted in
510 certain countries either by patents or by copyrighted interfaces, the
511 original copyright holder who places the Library under this License may add
512 an explicit geographical distribution limitation excluding those countries,
513 so that distribution is permitted only in or among countries not thus
514 excluded. In such case, this License incorporates the limitation as if
515 written in the body of this License.
516
517 <LI>
518
519 The Free Software Foundation may publish revised and/or new
520 versions of the Lesser General Public License from time to time.
521 Such new versions will be similar in spirit to the present version,
522 but may differ in detail to address new problems or concerns.
523
524 Each version is given a distinguishing version number. If the Library
525 specifies a version number of this License which applies to it and
526 "any later version", you have the option of following the terms and
527 conditions either of that version or of any later version published by
528 the Free Software Foundation. If the Library does not specify a
529 license version number, you may choose any version ever published by
530 the Free Software Foundation.
531
532 <LI>
533
534 If you wish to incorporate parts of the Library into other free
535 programs whose distribution conditions are incompatible with these,
536 write to the author to ask for permission. For software which is
537 copyrighted by the Free Software Foundation, write to the Free
538 Software Foundation; we sometimes make exceptions for this. Our
539 decision will be guided by the two goals of preserving the free status
540 of all derivatives of our free software and of promoting the sharing
541 and reuse of software generally.
542
543
544
545 <P><STRONG>NO WARRANTY</STRONG>
546
547 <LI>
548
549 BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
550 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
551 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
552 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
553 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
554 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
555 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
556 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
557 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
558
559 <LI>
560
561 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
562 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
563 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU

578 <H3>How to Apply These Terms to Your New Libraries</H3>
579
580 <P>
581 If you develop a new library, and you want it to be of the greatest
582 possible use to the public, we recommend making it free software that
583 everyone can redistribute and change. You can do so by permitting
584 redistribution under these terms (or, alternatively, under the terms of the
585 ordinary General Public License).
586
587
588 <P>
589 To apply these terms, attach the following notices to the library. It is
590 safest to attach them to the start of each source file to most effectively
591 convey the exclusion of warranty; and each file should have at least the
592 "copyright" line and a pointer to where the full notice is found.

622 school, if any, to sign a "copyright disclaimer" for the library, if
623 necessary. Here is a sample; alter the names:
