007:         GNU LESSER GENERAL PUBLIC LICENSE
008:         Version 2.1, February 1999
009:
010:         Copyright (C) 1991, 1999 Free Software Foundation, Inc.
011:         59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
012:         Everyone is permitted to copy and distribute verbatim copies
013:         of this license document, but changing it is not allowed.
014:
015:         [This is the first released version of the Lesser GPL.  It also counts
016:         as the successor of the GNU Library Public License, version 2, hence
017:         the version number 2.1.]
018:
019:         Preamble
020:
021:         The licenses for most software are designed to take away your
022:         freedom to share and change it.  By contrast, the GNU General Public
023:         Licenses are intended to guarantee your freedom to share and change
024:         free software--to make sure the software is free for all its users.
025:
026:         This license, the Lesser General Public License, applies to some
027:         specially designated software packages--typically libraries--of the
028:         Free Software Foundation and other authors who decide to use it.  You
029:         can use it too, but we suggest you first think carefully about whether
030:         this license or the ordinary General Public License is the better
031:         strategy to use in any particular case, based on the explanations
032:         below.
033:
034:         When we speak of free software, we are referring to freedom of use,
035:         not price.  Our General Public Licenses are designed to make sure that
036:         you have the freedom to distribute copies of free software (and charge
037:         for this service if you wish); that you receive source code or can get
038:         it if you want it; that you can change the software and use pieces of
039:         it in new free programs; and that you are informed that you can do
040:         these things.
041:
042:         To protect your rights, we need to make restrictions that forbid
043:         distributors to deny you these rights or to ask you to surrender these
044:         rights.  These restrictions translate to certain responsibilities for
045:         you if you distribute copies of the library or if you modify it.
046:
047:         For example, if you distribute copies of the library, whether gratis
048:         or for a fee, you must give the recipients all the rights that we gave
049:         you.  You must make sure that they, too, receive or can get the source
050:         code.  If you link other code with the library, you must provide
051:         complete object files to the recipients, so that they can relink them
052:         with the library after making changes to the library and recompiling
053:         it.  And you must show them these terms so they know their rights.
054:
055:         We protect your rights with a two-step method: (1) we copyright the
056:         library, and (2) we offer you this license, which gives you legal
057:         permission to copy, distribute and/or modify the library.
058:
059:         To protect each distributor, we want to make it very clear that
060:         there is no warranty for the free library.  Also, if the library is
061:         modified by someone else and passed on, the recipients should know
062:         that what they have is not the original version, so that the original
063:         author's reputation will not be affected by problems that might be
064:         introduced by others.
065:
066:         Finally, software patents pose a constant threat to the existence of
067:         any free program.  We wish to make sure that a company cannot
068:         effectively restrict the users of a free program by obtaining a
069:         restrictive license from a patent holder.  Therefore, we insist that
070:         any patent license obtained for a version of the library must be
071:         consistent with the full freedom of use specified in this license.
072:
073:         Most GNU software, including some libraries, is covered by the
074:         ordinary GNU General Public License.  This license, the GNU Lesser
075:         General Public License, applies to certain designated libraries, and
076:         is quite different from the ordinary General Public License.  We use
077:         this license for certain libraries in order to permit linking those
078:         libraries into non-free programs.
079:
080:         When a program is linked with a library, whether statically or using
081:         a shared library, the combination of the two is legally speaking a
082:         combined work, a derivative of the original library.  The ordinary
083:         General Public License therefore permits such linking only if the
084:         entire combination fits its criteria of freedom.  The Lesser General
085:         Public License permits more lax criteria for linking other code with
086:         the library.
087:
088:         We call this license the "Lesser" General Public License because it
089:         does Less to protect the user's freedom than the ordinary General
090:         Public License.  It also provides other free software developers Less
091:         of an advantage over competing non-free programs.  These disadvantages
092:         are the reason we use the ordinary General Public License for many
093:         libraries.  However, the Lesser license provides advantages in certain
094:         special circumstances.
095:
096:         For example, on rare occasions, there may be a special need to
097:         encourage the widest possible use of a certain library, so that it
098:         becomes a de-facto standard.  To achieve this, non-free programs must
099:         be allowed to use the library.  A more frequent case is that a free
100:         library does the same job as widely used non-free libraries.  In this
101:         case, there is little to gain by limiting the free library to free
102:         software only, so we use the Lesser General Public License.
103:
104:         In other cases, permission to use a particular library in non-free
105:         programs enables a greater number of people to use a large body of
106:         free software.  For example, permission to use the GNU C Library in
107:         non-free programs enables many more people to use the whole GNU
108:         operating system, as well as its variant, the GNU/Linux operating
109:         system.
110:
111:         Although the Lesser General Public License is Less protective of the
112:         users' freedom, it does ensure that the user of a program that is
113:         linked with the Library has the freedom and the wherewithal to run
114:         that program using a modified version of the Library.
115:
116:         The precise terms and conditions for copying, distribution and
117:         modification follow.  Pay close attention to the difference between a
118:         "work based on the library" and a "work that uses the library".  The
119:         former contains code derived from the library, whereas the latter must
120:         be combined with the library in order to run.
121:
122:
123:         GNU LESSER GENERAL PUBLIC LICENSE
124:         TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
125:
126:         0. This License Agreement applies to any software library or other
127:         program which contains a notice placed by the copyright holder or
128:         other authorized party saying it may be distributed under the terms of
129:         this Lesser General Public License (also called "this License").
130:         Each licensee is addressed as "you".
131:
132:         A "library" means a collection of software functions and/or data
133:         prepared so as to be conveniently linked with application programs
134:         (which use some of those functions and data) to form executables.
135:
136:         The "Library", below, refers to any such software library or work
137:         which has been distributed under these terms.  A "work based on the
138:         Library" means either the Library or any derivative work under
139:         copyright law: that is to say, a work containing the Library or a
140:         portion of it, either verbatim or with modifications and/or translated
141:         straightforwardly into another language.  (Hereinafter, translation is
142:         included without limitation in the term "modification".)
143:
144:         "Source code" for a work means the preferred form of the work for
145:         making modifications to it.  For a library, complete source code means
146:         all the source code for all modules it contains, plus any associated
147:         interface definition files, plus the scripts used to control
148:         compilation and installation of the library.
149:
150:         Activities other than copying, distribution and modification are not
151:         covered by this License; they are outside its scope.  The act of
152:         running a program using the Library is not restricted, and output from
153:         such a program is covered only if its contents constitute a work based
154:         on the Library (independent of the use of the Library in a tool for
155:         writing it).  Whether that is true depends on what the Library does
156:         and what the program that uses the Library does.
157:
158:         1. You may copy and distribute verbatim copies of the Library's
159:         complete source code as you receive it, in any medium, provided that
160:         you conspicuously and appropriately publish on each copy an
161:         appropriate copyright notice and disclaimer of warranty; keep intact
162:         all the notices that refer to this License and to the absence of any
163:         warranty; and distribute a copy of this License along with the
164:         Library.
165:
166:         You may charge a fee for the physical act of transferring a copy,
167:         and you may at your option offer warranty protection in exchange for a
168:         fee.
169:
170:         2. You may modify your copy or copies of the Library or any portion
171:         of it, thus forming a work based on the Library, and copy and
172:         distribute such modifications or work under the terms of Section 1
173:         above, provided that you also meet all of these conditions:
174:
175:         a) The modified work must itself be a software library.
176:
177:         b) You must cause the files modified to carry prominent notices
178:         stating that you changed the files and the date of any change.
179:
180:         c) You must cause the whole of the work to be licensed at no
181:         charge to all third parties under the terms of this License.
182:
183:         d) If a facility in the modified Library refers to a function or a
184:         table of data to be supplied by an application program that uses
185:         the facility, other than as an argument passed when the facility
186:         is invoked, then you must make a good faith effort to ensure that,
187:         in the event an application does not supply such function or
188:         table, the facility still operates, and performs whatever part of
189:         its purpose remains meaningful.
190:
191:         (For example, a function in a library to compute square roots has
192:         a purpose that is entirely well-defined independent of the
193:         application.  Therefore, Subsection 2d requires that any
194:         application-supplied function or table used by this function must
195:         be optional: if the application does not supply it, the square
196:         root function must still compute square roots.)
197:
198:         These requirements apply to the modified work as a whole.  If
199:         identifiable sections of that work are not derived from the Library,
200:         and can be reasonably considered independent and separate works in
201:         themselves, then this License, and its terms, do not apply to those
202:         sections when you distribute them as separate works.  But when you
203:         distribute the same sections as part of a whole which is a work based
204:         on the Library, the distribution of the whole must be on the terms of
205:         this License, whose permissions for other licensees extend to the
206:         entire whole, and thus to each and every part regardless of who wrote
207:         it.
208:
209:         Thus, it is not the intent of this section to claim rights or contest
210:         your rights to work written entirely by you; rather, the intent is to
211:         exercise the right to control the distribution of derivative or
212:         collective works based on the Library.
213:
214:         In addition, mere aggregation of another work not based on the Library
215:         with the Library (or with a work based on the Library) on a volume of
216:         a storage or distribution medium does not bring the other work under
217:         the scope of this License.
218:
219:         3. You may opt to apply the terms of the ordinary GNU General Public
220:         License instead of this License to a given copy of the Library.  To do
221:         this, you must alter all the notices that refer to this License, so
222:         that they refer to the ordinary GNU General Public License, version 2,
223:         instead of to this License.  (If a newer version than version 2 of the
224:         ordinary GNU General Public License has appeared, then you can specify
225:         that version instead if you wish.)  Do not make any other change in
226:         these notices.
227:
228:         Once this change is made in a given copy, it is irreversible for
229:         that copy, so the ordinary GNU General Public License applies to all
230:         subsequent copies and derivative works made from that copy.
231:
232:         This option is useful when you wish to copy part of the code of
233:         the Library into a program that is not a library.
234:
235:         4. You may copy and distribute the Library (or a portion or
236:         derivative of it, under Section 2) in object code or executable form
237:         under the terms of Sections 1 and 2 above provided that you accompany
238:         it with the complete corresponding machine-readable source code, which
239:         must be distributed under the terms of Sections 1 and 2 above on a
240:         medium customarily used for software interchange.
241:
242:         If distribution of object code is made by offering access to copy
243:         from a designated place, then offering equivalent access to copy the
244:         source code from the same place satisfies the requirement to
245:         distribute the source code, even though third parties are not
246:         compelled to copy the source along with the object code.
247:
248:         5. A program that contains no derivative of any portion of the
249:         Library, but is designed to work with the Library by being compiled or
250:         linked with it, is called a "work that uses the Library".  Such a
251:         work, in isolation, is not a derivative work of the Library, and
252:         therefore falls outside the scope of this License.
253:
254:         However, linking a "work that uses the Library" with the Library
255:         creates an executable that is a derivative of the Library (because it
256:         contains portions of the Library), rather than a "work that uses the
257:         library".  The executable is therefore covered by this License.
258:         Section 6 states terms for distribution of such executables.
259:
260:         When a "work that uses the Library" uses material from a header file
261:         that is part of the Library, the object code for the work may be a
262:         derivative work of the Library even though the source code is not.
263:         Whether this is true is especially significant if the work can be
264:         linked without the Library, or if the work is itself a library.  The
265:         threshold for this to be true is not precisely defined by law.
266:
267:         If such an object file uses only numerical parameters, data
268:         structure layouts and accessors, and small macros and small inline
269:         functions (ten lines or less in length), then the use of the object
270:         file is unrestricted, regardless of whether it is legally a derivative
271:         work.  (Executables containing this object code plus portions of the
272:         Library will still fall under Section 6.)
273:
274:         Otherwise, if the work is a derivative of the Library, you may
275:         distribute the object code for the work under the terms of Section 6.
276:         Any executables containing that work also fall under Section 6,
277:         whether or not they are linked directly with the Library itself.
278:
279:         6. As an exception to the Sections above, you may also combine or
280:         link a "work that uses the Library" with the Library to produce a
281:         work containing portions of the Library, and distribute that work
282:         under terms of your choice, provided that the terms permit
283:         modification of the work for the customer's own use and reverse
284:         engineering for debugging such modifications.
285:
286:         You must give prominent notice with each copy of the work that the
287:         Library is used in it and that the Library and its use are covered by
288:         this License.  You must supply a copy of this License.  If the work
289:         during execution displays copyright notices, you must include the
290:         copyright notice for the Library among them, as well as a reference
291:         directing the user to the copy of this License.  Also, you must do one
292:         of these things:
293:
294:         a) Accompany the work with the complete corresponding
295:         machine-readable source code for the Library including whatever
296:         changes were used in the work (which must be distributed under
297:         Sections 1 and 2 above); and, if the work is an executable linked
298:         with the Library, with the complete machine-readable "work that
299:         uses the Library", as object code and/or source code, so that the
300:         user can modify the Library and then relink to produce a modified
301:         executable containing the modified Library.  (It is understood
302:         that the user who changes the contents of definitions files in the
303:         Library will not necessarily be able to recompile the application
304:         to use the modified definitions.)
305:
306:         b) Use a suitable shared library mechanism for linking with the
307:         Library.  A suitable mechanism is one that (1) uses at run time a
308:         copy of the library already present on the user's computer system,
309:         rather than copying library functions into the executable, and (2)
310:         will operate properly with a modified version of the library, if
311:         the user installs one, as long as the modified version is
312:         interface-compatible with the version that the work was made with.
313:
314:         c) Accompany the work with a written offer, valid for at least
315:         three years, to give the same user the materials specified in
316:         Subsection 6a, above, for a charge no more than the cost of
317:         performing this distribution.
318:
319:         d) If distribution of the work is made by offering access to copy
320:         from a designated place, offer equivalent access to copy the above
321:         specified materials from the same place.
322:
323:         e) Verify that the user has already received a copy of these
324:         materials or that you have already sent this user a copy.
325:
326:         For an executable, the required form of the "work that uses the
327:         Library" must include any data and utility programs needed for
328:         reproducing the executable from it.  However, as a special exception,
329:         the materials to be distributed need not include anything that is
330:         normally distributed (in either source or binary form) with the major
331:         components (compiler, kernel, and so on) of the operating system on
332:         which the executable runs, unless that component itself accompanies
333:         the executable.
334:
335:         It may happen that this requirement contradicts the license
336:         restrictions of other proprietary libraries that do not normally
337:         accompany the operating system.  Such a contradiction means you cannot
338:         use both them and the Library together in an executable that you
339:         distribute.
340:
341:         7. You may place library facilities that are a work based on the
342:         Library side-by-side in a single library together with other library
343:         facilities not covered by this License, and distribute such a combined
344:         library, provided that the separate distribution of the work based on
345:         the Library and of the other library facilities is otherwise
346:         permitted, and provided that you do these two things:
347:
348:         a) Accompany the combined library with a copy of the same work
349:         based on the Library, uncombined with any other library
350:         facilities.  This must be distributed under the terms of the
351:         Sections above.
352:
353:         b) Give prominent notice with the combined library of the fact
354:         that part of it is a work based on the Library, and explaining
355:         where to find the accompanying uncombined form of the same work.
356:
357:         8. You may not copy, modify, sublicense, link with, or distribute
358:         the Library except as expressly provided under this License.  Any
359:         attempt otherwise to copy, modify, sublicense, link with, or
360:         distribute the Library is void, and will automatically terminate your
361:         rights under this License.  However, parties who have received copies,
362:         or rights, from you under this License will not have their licenses
363:         terminated so long as such parties remain in full compliance.
364:
365:         9. You are not required to accept this License, since you have not
366:         signed it.  However, nothing else grants you permission to modify or
367:         distribute the Library or its derivative works.  These actions are
368:         prohibited by law if you do not accept this License.  Therefore, by
369:         modifying or distributing the Library (or any work based on the
370:         Library), you indicate your acceptance of this License to do so, and
371:         all its terms and conditions for copying, distributing or modifying
372:         the Library or works based on it.
373:
374:         10. Each time you redistribute the Library (or any work based on the
375:         Library), the recipient automatically receives a license from the
376:         original licensor to copy, distribute, link with or modify the Library
377:         subject to these terms and conditions.  You may not impose any further
378:         restrictions on the recipients' exercise of the rights granted herein.
379:         You are not responsible for enforcing compliance by third parties with
380:         this License.
381:
382:         11. If, as a consequence of a court judgment or allegation of patent
383:         infringement or for any other reason (not limited to patent issues),
384:         conditions are imposed on you (whether by court order, agreement or
385:         otherwise) that contradict the conditions of this License, they do not
386:         excuse you from the conditions of this License.  If you cannot
387:         distribute so as to satisfy simultaneously your obligations under this
388:         License and any other pertinent obligations, then as a consequence you
389:         may not distribute the Library at all.  For example, if a patent
390:         license would not permit royalty-free redistribution of the Library by
391:         all those who receive copies directly or indirectly through you, then
392:         the only way you could satisfy both it and this License would be to
393:         refrain entirely from distribution of the Library.
394:
395:         If any portion of this section is held invalid or unenforceable under
396:         any particular circumstance, the balance of the section is intended to
397:         apply, and the section as a whole is intended to apply in other
398:         circumstances.
399:
400:         It is not the purpose of this section to induce you to infringe any
401:         patents or other property right claims or to contest validity of any
402:         such claims; this section has the sole purpose of protecting the
403:         integrity of the free software distribution system which is
404:         implemented by public license practices.  Many people have made
405:         generous contributions to the wide range of software distributed
406:         through that system in reliance on consistent application of that
407:         system; it is up to the author/donor to decide if he or she is willing
408:         to distribute software through any other system and a licensee cannot
409:         impose that choice.
410:
411:         This section is intended to make thoroughly clear what is believed to
412:         be a consequence of the rest of this License.
413:
414:         12. If the distribution and/or use of the Library is restricted in
415:         certain countries either by patents or by copyrighted interfaces, the
416:         original copyright holder who places the Library under this License
417:         may add an explicit geographical distribution limitation excluding those
418:         countries, so that distribution is permitted only in or among
419:         countries not thus excluded.  In such case, this License incorporates
420:         the limitation as if written in the body of this License.
421:
422:         13. The Free Software Foundation may publish revised and/or new
423:         versions of the Lesser General Public License from time to time.
424:         Such new versions will be similar in spirit to the present version,
425:         but may differ in detail to address new problems or concerns.
426:
427:         Each version is given a distinguishing version number.  If the Library
428:         specifies a version number of this License which applies to it and
429:         "any later version", you have the option of following the terms and
430:         conditions either of that version or of any later version published by
431:         the Free Software Foundation.  If the Library does not specify a
432:         license version number, you may choose any version ever published by
433:         the Free Software Foundation.
434:
435:         14. If you wish to incorporate parts of the Library into other free
436:         programs whose distribution conditions are incompatible with these,
437:         write to the author to ask for permission.  For software which is
438:         copyrighted by the Free Software Foundation, write to the Free
439:         Software Foundation; we sometimes make exceptions for this.  Our
440:         decision will be guided by the two goals of preserving the free status
441:         of all derivatives of our free software and of promoting the sharing
442:         and reuse of software generally.
443:
444:         NO WARRANTY
445:
446:         15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
447:         WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
448:         EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
449:         OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
450:         KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
451:         IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
452:         PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
453:         LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
454:         THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
455:
456:         16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
457:         WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
458:         AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
459:         FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
460:         CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
461:         LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
462:         RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
463:         FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
464:         SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
465:         DAMAGES.
466:
467:         END OF TERMS AND CONDITIONS
