  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 |   library `Frob' (a library for tweaking knobs) written by James Random Hacker.
