30 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
31 Everyone is permitted to copy and distribute verbatim copies
32 of this license document, but changing it is not allowed.
33
34 Preamble
35
36 The licenses for most software are designed to take away your
37 freedom to share and change it. By contrast, the GNU General Public
38 License is intended to guarantee your freedom to share and change free
39 software--to make sure the software is free for all its users. This
40 General Public License applies to most of the Free Software
41 Foundation's software and to any other program whose authors commit to
42 using it. (Some other Free Software Foundation software is covered by
43 the GNU Library General Public License instead.) You can apply it to
44 your programs, too.
45
46 When we speak of free software, we are referring to freedom, not
47 price. Our General Public Licenses are designed to make sure that you
48 have the freedom to distribute copies of free software (and charge for
49 this service if you wish), that you receive source code or can get it
50 if you want it, that you can change the software or use pieces of it
51 in new free programs; and that you know you can do these things.
52
53 To protect your rights, we need to make restrictions that forbid
54 anyone to deny you these rights or to ask you to surrender the rights.
55 These restrictions translate to certain responsibilities for you if you
56 distribute copies of the software, or if you modify it.
57
58 For example, if you distribute copies of such a program, whether
59 gratis or for a fee, you must give the recipients all the rights that
60 you have. You must make sure that they, too, receive or can get the
61 source code. And you must show them these terms so they know their
62 rights.
63
64 We protect your rights with two steps: (1) copyright the software, and
65 (2) offer you this license which gives you legal permission to copy,
66 distribute and/or modify the software.
67
68 Also, for each author's protection and ours, we want to make certain
69 that everyone understands that there is no warranty for this free
70 software. If the software is modified by someone else and passed on, we
71 want its recipients to know that what they have is not the original, so
72 that any problems introduced by others will not reflect on the original
73 authors' reputations.
74
75 Finally, any free program is threatened constantly by software
76 patents. We wish to avoid the danger that redistributors of a free
77 program will individually obtain patent licenses, in effect making the
78 program proprietary. To prevent this, we have made it clear that any
79 patent must be licensed for everyone's free use or not licensed at all.
80
81 The precise terms and conditions for copying, distribution and
82 modification follow.
83 \f
84 GNU GENERAL PUBLIC LICENSE
85 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
86
87 0. This License applies to any program or other work which contains
88 a notice placed by the copyright holder saying it may be distributed
89 under the terms of this General Public License. The "Program", below,
90 refers to any such program or work, and a "work based on the Program"
91 means either the Program or any derivative work under copyright law:
92 that is to say, a work containing the Program or a portion of it,
93 either verbatim or with modifications and/or translated into another
94 language. (Hereinafter, translation is included without limitation in
95 the term "modification".) Each licensee is addressed as "you".
96
97 Activities other than copying, distribution and modification are not
98 covered by this License; they are outside its scope. The act of
99 running the Program is not restricted, and the output from the Program
100 is covered only if its contents constitute a work based on the
101 Program (independent of having been made by running the Program).
102 Whether that is true depends on what the Program does.
103
104 1. You may copy and distribute verbatim copies of the Program's
105 source code as you receive it, in any medium, provided that you
106 conspicuously and appropriately publish on each copy an appropriate
107 copyright notice and disclaimer of warranty; keep intact all the
108 notices that refer to this License and to the absence of any warranty;
109 and give any other recipients of the Program a copy of this License
110 along with the Program.
111
112 You may charge a fee for the physical act of transferring a copy, and
113 you may at your option offer warranty protection in exchange for a fee.
114
115 2. You may modify your copy or copies of the Program or any portion
116 of it, thus forming a work based on the Program, and copy and
117 distribute such modifications or work under the terms of Section 1
118 above, provided that you also meet all of these conditions:
119
120 a) You must cause the modified files to carry prominent notices
121 stating that you changed the files and the date of any change.
122
123 b) You must cause any work that you distribute or publish, that in
124 whole or in part contains or is derived from the Program or any
125 part thereof, to be licensed as a whole at no charge to all third
126 parties under the terms of this License.
127
128 c) If the modified program normally reads commands interactively
129 when run, you must cause it, when started running for such
130 interactive use in the most ordinary way, to print or display an
131 announcement including an appropriate copyright notice and a
132 notice that there is no warranty (or else, saying that you provide
133 a warranty) and that users may redistribute the program under
134 these conditions, and telling the user how to view a copy of this
135 License. (Exception: if the Program itself is interactive but
136 does not normally print such an announcement, your work based on
137 the Program is not required to print an announcement.)
138 \f
139 These requirements apply to the modified work as a whole. If
140 identifiable sections of that work are not derived from the Program,
141 and can be reasonably considered independent and separate works in
142 themselves, then this License, and its terms, do not apply to those
143 sections when you distribute them as separate works. But when you
144 distribute the same sections as part of a whole which is a work based
145 on the Program, the distribution of the whole must be on the terms of
146 this License, whose permissions for other licensees extend to the
147 entire whole, and thus to each and every part regardless of who wrote it.
148
149 Thus, it is not the intent of this section to claim rights or contest
150 your rights to work written entirely by you; rather, the intent is to
151 exercise the right to control the distribution of derivative or
152 collective works based on the Program.
153
154 In addition, mere aggregation of another work not based on the Program
155 with the Program (or with a work based on the Program) on a volume of
156 a storage or distribution medium does not bring the other work under
157 the scope of this License.
158
159 3. You may copy and distribute the Program (or a work based on it,
160 under Section 2) in object code or executable form under the terms of
161 Sections 1 and 2 above provided that you also do one of the following:
162
163 a) Accompany it with the complete corresponding machine-readable
164 source code, which must be distributed under the terms of Sections
165 1 and 2 above on a medium customarily used for software interchange; or,
166
167 b) Accompany it with a written offer, valid for at least three
168 years, to give any third party, for a charge no more than your
169 cost of physically performing source distribution, a complete
170 machine-readable copy of the corresponding source code, to be
171 distributed under the terms of Sections 1 and 2 above on a medium
172 customarily used for software interchange; or,
173
174 c) Accompany it with the information you received as to the offer
175 to distribute corresponding source code. (This alternative is
176 allowed only for noncommercial distribution and only if you
177 received the program in object code or executable form with such
178 an offer, in accord with Subsection b above.)
179
180 The source code for a work means the preferred form of the work for
181 making modifications to it. For an executable work, complete source
182 code means all the source code for all modules it contains, plus any
183 associated interface definition files, plus the scripts used to
184 control compilation and installation of the executable. However, as a
185 special exception, the source code distributed need not include
186 anything that is normally distributed (in either source or binary
187 form) with the major components (compiler, kernel, and so on) of the
188 operating system on which the executable runs, unless that component
189 itself accompanies the executable.
190
191 If distribution of executable or object code is made by offering
192 access to copy from a designated place, then offering equivalent
193 access to copy the source code from the same place counts as
194 distribution of the source code, even though third parties are not
195 compelled to copy the source along with the object code.
196 \f
197 4. You may not copy, modify, sublicense, or distribute the Program
198 except as expressly provided under this License. Any attempt
199 otherwise to copy, modify, sublicense or distribute the Program is
200 void, and will automatically terminate your rights under this License.
201 However, parties who have received copies, or rights, from you under
202 this License will not have their licenses terminated so long as such
203 parties remain in full compliance.
204
205 5. You are not required to accept this License, since you have not
206 signed it. However, nothing else grants you permission to modify or
207 distribute the Program or its derivative works. These actions are
208 prohibited by law if you do not accept this License. Therefore, by
209 modifying or distributing the Program (or any work based on the
210 Program), you indicate your acceptance of this License to do so, and
211 all its terms and conditions for copying, distributing or modifying
212 the Program or works based on it.
213
214 6. Each time you redistribute the Program (or any work based on the
215 Program), the recipient automatically receives a license from the
216 original licensor to copy, distribute or modify the Program subject to
217 these terms and conditions. You may not impose any further
218 restrictions on the recipients' exercise of the rights granted herein.
219 You are not responsible for enforcing compliance by third parties to
220 this License.
221
222 7. If, as a consequence of a court judgment or allegation of patent
223 infringement or for any other reason (not limited to patent issues),
224 conditions are imposed on you (whether by court order, agreement or
225 otherwise) that contradict the conditions of this License, they do not
226 excuse you from the conditions of this License. If you cannot
227 distribute so as to satisfy simultaneously your obligations under this
228 License and any other pertinent obligations, then as a consequence you
229 may not distribute the Program at all. For example, if a patent
230 license would not permit royalty-free redistribution of the Program by
231 all those who receive copies directly or indirectly through you, then
232 the only way you could satisfy both it and this License would be to
233 refrain entirely from distribution of the Program.
234
235 If any portion of this section is held invalid or unenforceable under
236 any particular circumstance, the balance of the section is intended to
237 apply and the section as a whole is intended to apply in other
238 circumstances.
239
240 It is not the purpose of this section to induce you to infringe any
241 patents or other property right claims or to contest validity of any
242 such claims; this section has the sole purpose of protecting the
243 integrity of the free software distribution system, which is
244 implemented by public license practices. Many people have made
245 generous contributions to the wide range of software distributed
246 through that system in reliance on consistent application of that
247 system; it is up to the author/donor to decide if he or she is willing
248 to distribute software through any other system and a licensee cannot
249 impose that choice.
250
251 This section is intended to make thoroughly clear what is believed to
252 be a consequence of the rest of this License.
253 \f
254 8. If the distribution and/or use of the Program is restricted in
255 certain countries either by patents or by copyrighted interfaces, the
256 original copyright holder who places the Program under this License
257 may add an explicit geographical distribution limitation excluding
258 those countries, so that distribution is permitted only in or among
259 countries not thus excluded. In such case, this License incorporates
260 the limitation as if written in the body of this License.
261
262 9. The Free Software Foundation may publish revised and/or new versions
263 of the General Public License from time to time. Such new versions will
264 be similar in spirit to the present version, but may differ in detail to
265 address new problems or concerns.
266
267 Each version is given a distinguishing version number. If the Program
268 specifies a version number of this License which applies to it and "any
269 later version", you have the option of following the terms and conditions
270 either of that version or of any later version published by the Free
271 Software Foundation. If the Program does not specify a version number of
272 this License, you may choose any version ever published by the Free Software
273 Foundation.
274
275 10. If you wish to incorporate parts of the Program into other free
276 programs whose distribution conditions are different, write to the author
277 to ask for permission. For software which is copyrighted by the Free
278 Software Foundation, write to the Free Software Foundation; we sometimes
279 make exceptions for this. Our decision will be guided by the two goals
280 of preserving the free status of all derivatives of our free software and
281 of promoting the sharing and reuse of software generally.
282
283 NO WARRANTY
284
285 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
286 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
287 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
288 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
289 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
290 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
291 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
292 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
293 REPAIR OR CORRECTION.
294
295 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
296 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
297 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
298 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
299 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
300 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
301 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
302 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
303 POSSIBILITY OF SUCH DAMAGES.
304
305 END OF TERMS AND CONDITIONS
306 \f
307 How to Apply These Terms to Your New Programs
308
309 If you develop a new program, and you want it to be of the greatest
310 possible use to the public, the best way to achieve this is to make it
311 free software which everyone can redistribute and change under these terms.
312
313 To do so, attach the following notices to the program. It is safest
314 to attach them to the start of each source file to most effectively
315 convey the exclusion of warranty; and each file should have at least
316 the "copyright" line and a pointer to where the full notice is found.
317
318 <one line to give the program's name and a brief idea of what it does.>
319 Copyright (C) <year> <name of author>
320
321 This program is free software; you can redistribute it and/or modify
322 it under the terms of the GNU General Public License as published by
323 the Free Software Foundation; either version 2 of the License, or
324 (at your option) any later version.
325
326 This program is distributed in the hope that it will be useful,
327 but WITHOUT ANY WARRANTY; without even the implied warranty of
328 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
329 GNU General Public License for more details.
330
331 You should have received a copy of the GNU General Public License
332 along with this program; if not, write to the Free Software
333 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
334
335
336 Also add information on how to contact you by electronic and paper mail.
337
338 If the program is interactive, make it output a short notice like this
339 when it starts in an interactive mode:
340
341 Gnomovision version 69, Copyright (C) year name of author
342 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
343 This is free software, and you are welcome to redistribute it
344 under certain conditions; type `show c' for details.
345
346 The hypothetical commands `show w' and `show c' should show the appropriate
347 parts of the General Public License. Of course, the commands you use may
348 be called something other than `show w' and `show c'; they could even be
349 mouse-clicks or menu items--whatever suits your program.
350
351 You should also get your employer (if you work as a programmer) or your
352 school, if any, to sign a "copyright disclaimer" for the program, if
353 necessary. Here is a sample; alter the names:
354
355 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
356 `Gnomovision' (which makes passes at compilers) written by James Hacker.

359 Ty Coon, President of Vice
360
361 This General Public License does not permit incorporating your program into
362 proprietary programs. If your program is a subroutine library, you may
363 consider it more useful to permit linking proprietary applications with the
364 library. If this is what you want to do, use the GNU Library General
365 Public License instead of this License.

369 GNU LESSER GENERAL PUBLIC LICENSE
370 Version 2.1, February 1999
371
372 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
373 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
374 Everyone is permitted to copy and distribute verbatim copies
375 of this license document, but changing it is not allowed.
376
377 [This is the first released version of the Lesser GPL. It also counts
378 as the successor of the GNU Library Public License, version 2, hence
379 the version number 2.1.]
380
381 Preamble
382
383 The licenses for most software are designed to take away your
384 freedom to share and change it. By contrast, the GNU General Public
385 Licenses are intended to guarantee your freedom to share and change
386 free software--to make sure the software is free for all its users.
387
388 This license, the Lesser General Public License, applies to some
389 specially designated software packages--typically libraries--of the
390 Free Software Foundation and other authors who decide to use it. You
391 can use it too, but we suggest you first think carefully about whether
392 this license or the ordinary General Public License is the better
393 strategy to use in any particular case, based on the explanations below.
394
395 When we speak of free software, we are referring to freedom of use,
396 not price. Our General Public Licenses are designed to make sure that
397 you have the freedom to distribute copies of free software (and charge
398 for this service if you wish); that you receive source code or can get
399 it if you want it; that you can change the software and use pieces of
400 it in new free programs; and that you are informed that you can do
401 these things.
402
403 To protect your rights, we need to make restrictions that forbid
404 distributors to deny you these rights or to ask you to surrender these
405 rights. These restrictions translate to certain responsibilities for
406 you if you distribute copies of the library or if you modify it.
407
408 For example, if you distribute copies of the library, whether gratis
409 or for a fee, you must give the recipients all the rights that we gave
410 you. You must make sure that they, too, receive or can get the source
411 code. If you link other code with the library, you must provide
412 complete object files to the recipients, so that they can relink them
413 with the library after making changes to the library and recompiling
414 it. And you must show them these terms so they know their rights.
415
416 We protect your rights with a two-step method: (1) we copyright the
417 library, and (2) we offer you this license, which gives you legal
418 permission to copy, distribute and/or modify the library.
419
420 To protect each distributor, we want to make it very clear that
421 there is no warranty for the free library. Also, if the library is
422 modified by someone else and passed on, the recipients should know
423 that what they have is not the original version, so that the original
424 author's reputation will not be affected by problems that might be
425 introduced by others.
426 \f
427 Finally, software patents pose a constant threat to the existence of
428 any free program. We wish to make sure that a company cannot
429 effectively restrict the users of a free program by obtaining a
430 restrictive license from a patent holder. Therefore, we insist that
431 any patent license obtained for a version of the library must be
432 consistent with the full freedom of use specified in this license.
433
434 Most GNU software, including some libraries, is covered by the
435 ordinary GNU General Public License. This license, the GNU Lesser
436 General Public License, applies to certain designated libraries, and
437 is quite different from the ordinary General Public License. We use
438 this license for certain libraries in order to permit linking those
439 libraries into non-free programs.
440
441 When a program is linked with a library, whether statically or using
442 a shared library, the combination of the two is legally speaking a
443 combined work, a derivative of the original library. The ordinary
444 General Public License therefore permits such linking only if the
445 entire combination fits its criteria of freedom. The Lesser General
446 Public License permits more lax criteria for linking other code with
447 the library.
448
449 We call this license the "Lesser" General Public License because it
450 does Less to protect the user's freedom than the ordinary General
451 Public License. It also provides other free software developers Less
452 of an advantage over competing non-free programs. These disadvantages
453 are the reason we use the ordinary General Public License for many
454 libraries. However, the Lesser license provides advantages in certain
455 special circumstances.
456
457 For example, on rare occasions, there may be a special need to
458 encourage the widest possible use of a certain library, so that it becomes
459 a de-facto standard. To achieve this, non-free programs must be
460 allowed to use the library. A more frequent case is that a free
461 library does the same job as widely used non-free libraries. In this
462 case, there is little to gain by limiting the free library to free
463 software only, so we use the Lesser General Public License.
464
465 In other cases, permission to use a particular library in non-free
466 programs enables a greater number of people to use a large body of
467 free software. For example, permission to use the GNU C Library in
468 non-free programs enables many more people to use the whole GNU
469 operating system, as well as its variant, the GNU/Linux operating
470 system.
471
472 Although the Lesser General Public License is Less protective of the
473 users' freedom, it does ensure that the user of a program that is
474 linked with the Library has the freedom and the wherewithal to run
475 that program using a modified version of the Library.
476
477 The precise terms and conditions for copying, distribution and
478 modification follow. Pay close attention to the difference between a
479 "work based on the library" and a "work that uses the library". The
480 former contains code derived from the library, whereas the latter must
481 be combined with the library in order to run.
482 \f
483 GNU LESSER GENERAL PUBLIC LICENSE
484 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
485
486 0. This License Agreement applies to any software library or other
487 program which contains a notice placed by the copyright holder or
488 other authorized party saying it may be distributed under the terms of
489 this Lesser General Public License (also called "this License").
490 Each licensee is addressed as "you".
491
492 A "library" means a collection of software functions and/or data
493 prepared so as to be conveniently linked with application programs
494 (which use some of those functions and data) to form executables.
495
496 The "Library", below, refers to any such software library or work
497 which has been distributed under these terms. A "work based on the
498 Library" means either the Library or any derivative work under
499 copyright law: that is to say, a work containing the Library or a
500 portion of it, either verbatim or with modifications and/or translated
501 straightforwardly into another language. (Hereinafter, translation is
502 included without limitation in the term "modification".)
503
504 "Source code" for a work means the preferred form of the work for
505 making modifications to it. For a library, complete source code means
506 all the source code for all modules it contains, plus any associated
507 interface definition files, plus the scripts used to control compilation
508 and installation of the library.
509
510 Activities other than copying, distribution and modification are not
511 covered by this License; they are outside its scope. The act of
512 running a program using the Library is not restricted, and output from
513 such a program is covered only if its contents constitute a work based
514 on the Library (independent of the use of the Library in a tool for
515 writing it). Whether that is true depends on what the Library does
516 and what the program that uses the Library does.
517
518 1. You may copy and distribute verbatim copies of the Library's
519 complete source code as you receive it, in any medium, provided that
520 you conspicuously and appropriately publish on each copy an
521 appropriate copyright notice and disclaimer of warranty; keep intact
522 all the notices that refer to this License and to the absence of any
523 warranty; and distribute a copy of this License along with the
524 Library.
525
526 You may charge a fee for the physical act of transferring a copy,
527 and you may at your option offer warranty protection in exchange for a
528 fee.
529 \f
530 2. You may modify your copy or copies of the Library or any portion
531 of it, thus forming a work based on the Library, and copy and
532 distribute such modifications or work under the terms of Section 1
533 above, provided that you also meet all of these conditions:
534
535 a) The modified work must itself be a software library.
536
537 b) You must cause the files modified to carry prominent notices
538 stating that you changed the files and the date of any change.
539
540 c) You must cause the whole of the work to be licensed at no
541 charge to all third parties under the terms of this License.
542
543 d) If a facility in the modified Library refers to a function or a
544 table of data to be supplied by an application program that uses
545 the facility, other than as an argument passed when the facility
546 is invoked, then you must make a good faith effort to ensure that,
547 in the event an application does not supply such function or
548 table, the facility still operates, and performs whatever part of
549 its purpose remains meaningful.
550
551 (For example, a function in a library to compute square roots has
552 a purpose that is entirely well-defined independent of the
553 application. Therefore, Subsection 2d requires that any
554 application-supplied function or table used by this function must
555 be optional: if the application does not supply it, the square
556 root function must still compute square roots.)
557
558 These requirements apply to the modified work as a whole. If
559 identifiable sections of that work are not derived from the Library,
560 and can be reasonably considered independent and separate works in
561 themselves, then this License, and its terms, do not apply to those
562 sections when you distribute them as separate works. But when you
563 distribute the same sections as part of a whole which is a work based
564 on the Library, the distribution of the whole must be on the terms of
565 this License, whose permissions for other licensees extend to the
566 entire whole, and thus to each and every part regardless of who wrote
567 it.
568
569 Thus, it is not the intent of this section to claim rights or contest
570 your rights to work written entirely by you; rather, the intent is to
571 exercise the right to control the distribution of derivative or
572 collective works based on the Library.
573
574 In addition, mere aggregation of another work not based on the Library
575 with the Library (or with a work based on the Library) on a volume of
576 a storage or distribution medium does not bring the other work under
577 the scope of this License.
578
579 3. You may opt to apply the terms of the ordinary GNU General Public
580 License instead of this License to a given copy of the Library. To do
581 this, you must alter all the notices that refer to this License, so
582 that they refer to the ordinary GNU General Public License, version 2,
583 instead of to this License. (If a newer version than version 2 of the
584 ordinary GNU General Public License has appeared, then you can specify
585 that version instead if you wish.) Do not make any other change in
586 these notices.
587 \f
588 Once this change is made in a given copy, it is irreversible for
589 that copy, so the ordinary GNU General Public License applies to all
590 subsequent copies and derivative works made from that copy.
591
592 This option is useful when you wish to copy part of the code of
593 the Library into a program that is not a library.
594
595 4. You may copy and distribute the Library (or a portion or
596 derivative of it, under Section 2) in object code or executable form
597 under the terms of Sections 1 and 2 above provided that you accompany
598 it with the complete corresponding machine-readable source code, which
599 must be distributed under the terms of Sections 1 and 2 above on a
600 medium customarily used for software interchange.
601
602 If distribution of object code is made by offering access to copy
603 from a designated place, then offering equivalent access to copy the
604 source code from the same place satisfies the requirement to
605 distribute the source code, even though third parties are not
606 compelled to copy the source along with the object code.
607
608 5. A program that contains no derivative of any portion of the
609 Library, but is designed to work with the Library by being compiled or
610 linked with it, is called a "work that uses the Library". Such a
611 work, in isolation, is not a derivative work of the Library, and
612 therefore falls outside the scope of this License.
613
614 However, linking a "work that uses the Library" with the Library
615 creates an executable that is a derivative of the Library (because it
616 contains portions of the Library), rather than a "work that uses the
617 library". The executable is therefore covered by this License.
618 Section 6 states terms for distribution of such executables.
619
620 When a "work that uses the Library" uses material from a header file
621 that is part of the Library, the object code for the work may be a
622 derivative work of the Library even though the source code is not.
623 Whether this is true is especially significant if the work can be
624 linked without the Library, or if the work is itself a library. The
625 threshold for this to be true is not precisely defined by law.
626
627 If such an object file uses only numerical parameters, data
628 structure layouts and accessors, and small macros and small inline
629 functions (ten lines or less in length), then the use of the object
630 file is unrestricted, regardless of whether it is legally a derivative
631 work. (Executables containing this object code plus portions of the
632 Library will still fall under Section 6.)
633
634 Otherwise, if the work is a derivative of the Library, you may
635 distribute the object code for the work under the terms of Section 6.
636 Any executables containing that work also fall under Section 6,
637 whether or not they are linked directly with the Library itself.
638 \f
639 6. As an exception to the Sections above, you may also combine or
640 link a "work that uses the Library" with the Library to produce a
641 work containing portions of the Library, and distribute that work
642 under terms of your choice, provided that the terms permit
643 modification of the work for the customer's own use and reverse
644 engineering for debugging such modifications.
645
646 You must give prominent notice with each copy of the work that the
647 Library is used in it and that the Library and its use are covered by
648 this License. You must supply a copy of this License. If the work
649 during execution displays copyright notices, you must include the
650 copyright notice for the Library among them, as well as a reference
651 directing the user to the copy of this License. Also, you must do one
652 of these things:
653
654 a) Accompany the work with the complete corresponding
655 machine-readable source code for the Library including whatever
656 changes were used in the work (which must be distributed under
657 Sections 1 and 2 above); and, if the work is an executable linked
658 with the Library, with the complete machine-readable "work that
659 uses the Library", as object code and/or source code, so that the
660 user can modify the Library and then relink to produce a modified
661 executable containing the modified Library. (It is understood
662 that the user who changes the contents of definitions files in the
663 Library will not necessarily be able to recompile the application
664 to use the modified definitions.)
665
666 b) Use a suitable shared library mechanism for linking with the
667 Library. A suitable mechanism is one that (1) uses at run time a
668 copy of the library already present on the user's computer system,
669 rather than copying library functions into the executable, and (2)
670 will operate properly with a modified version of the library, if
671 the user installs one, as long as the modified version is
672 interface-compatible with the version that the work was made with.
673
674 c) Accompany the work with a written offer, valid for at
675 least three years, to give the same user the materials
676 specified in Subsection 6a, above, for a charge no more
677 than the cost of performing this distribution.
678
679 d) If distribution of the work is made by offering access to copy
680 from a designated place, offer equivalent access to copy the above
681 specified materials from the same place.
682
683 e) Verify that the user has already received a copy of these
684 materials or that you have already sent this user a copy.
685
686 For an executable, the required form of the "work that uses the
687 Library" must include any data and utility programs needed for
688 reproducing the executable from it. However, as a special exception,
689 the materials to be distributed need not include anything that is
690 normally distributed (in either source or binary form) with the major
691 components (compiler, kernel, and so on) of the operating system on
692 which the executable runs, unless that component itself accompanies
693 the executable.
694
695 It may happen that this requirement contradicts the license
696 restrictions of other proprietary libraries that do not normally
697 accompany the operating system. Such a contradiction means you cannot
698 use both them and the Library together in an executable that you
699 distribute.
700 \f
701 7. You may place library facilities that are a work based on the
702 Library side-by-side in a single library together with other library
703 facilities not covered by this License, and distribute such a combined
704 library, provided that the separate distribution of the work based on
705 the Library and of the other library facilities is otherwise
706 permitted, and provided that you do these two things:
707
708 a) Accompany the combined library with a copy of the same work
709 based on the Library, uncombined with any other library
710 facilities. This must be distributed under the terms of the
711 Sections above.
712
713 b) Give prominent notice with the combined library of the fact
714 that part of it is a work based on the Library, and explaining
715 where to find the accompanying uncombined form of the same work.
716
717 8. You may not copy, modify, sublicense, link with, or distribute
718 the Library except as expressly provided under this License. Any
719 attempt otherwise to copy, modify, sublicense, link with, or
720 distribute the Library is void, and will automatically terminate your
721 rights under this License. However, parties who have received copies,
722 or rights, from you under this License will not have their licenses
723 terminated so long as such parties remain in full compliance.
724
725 9. You are not required to accept this License, since you have not
726 signed it. However, nothing else grants you permission to modify or
727 distribute the Library or its derivative works. These actions are
728 prohibited by law if you do not accept this License. Therefore, by
729 modifying or distributing the Library (or any work based on the
730 Library), you indicate your acceptance of this License to do so, and
731 all its terms and conditions for copying, distributing or modifying
732 the Library or works based on it.
733
734 10. Each time you redistribute the Library (or any work based on the
735 Library), the recipient automatically receives a license from the
736 original licensor to copy, distribute, link with or modify the Library
737 subject to these terms and conditions. You may not impose any further
738 restrictions on the recipients' exercise of the rights granted herein.
739 You are not responsible for enforcing compliance by third parties with
740 this License.
741 \f
742 11. If, as a consequence of a court judgment or allegation of patent
743 infringement or for any other reason (not limited to patent issues),
744 conditions are imposed on you (whether by court order, agreement or
745 otherwise) that contradict the conditions of this License, they do not
746 excuse you from the conditions of this License. If you cannot
747 distribute so as to satisfy simultaneously your obligations under this
748 License and any other pertinent obligations, then as a consequence you
749 may not distribute the Library at all. For example, if a patent
750 license would not permit royalty-free redistribution of the Library by
751 all those who receive copies directly or indirectly through you, then
752 the only way you could satisfy both it and this License would be to
753 refrain entirely from distribution of the Library.
754
755 If any portion of this section is held invalid or unenforceable under any
756 particular circumstance, the balance of the section is intended to apply,
757 and the section as a whole is intended to apply in other circumstances.
758
759 It is not the purpose of this section to induce you to infringe any
760 patents or other property right claims or to contest validity of any
761 such claims; this section has the sole purpose of protecting the
762 integrity of the free software distribution system which is
763 implemented by public license practices. Many people have made
764 generous contributions to the wide range of software distributed
765 through that system in reliance on consistent application of that
766 system; it is up to the author/donor to decide if he or she is willing
767 to distribute software through any other system and a licensee cannot
768 impose that choice.
769
770 This section is intended to make thoroughly clear what is believed to
771 be a consequence of the rest of this License.
772
773 12. If the distribution and/or use of the Library is restricted in
774 certain countries either by patents or by copyrighted interfaces, the
775 original copyright holder who places the Library under this License may add
776 an explicit geographical distribution limitation excluding those countries,
777 so that distribution is permitted only in or among countries not thus
778 excluded. In such case, this License incorporates the limitation as if
779 written in the body of this License.
780
781 13. The Free Software Foundation may publish revised and/or new
782 versions of the Lesser General Public License from time to time.
783 Such new versions will be similar in spirit to the present version,
784 but may differ in detail to address new problems or concerns.
785
786 Each version is given a distinguishing version number. If the Library
787 specifies a version number of this License which applies to it and
788 "any later version", you have the option of following the terms and
789 conditions either of that version or of any later version published by
790 the Free Software Foundation. If the Library does not specify a
791 license version number, you may choose any version ever published by
792 the Free Software Foundation.
793 \f
794 14. If you wish to incorporate parts of the Library into other free
795 programs whose distribution conditions are incompatible with these,
796 write to the author to ask for permission. For software which is
797 copyrighted by the Free Software Foundation, write to the Free
798 Software Foundation; we sometimes make exceptions for this. Our
799 decision will be guided by the two goals of preserving the free status
800 of all derivatives of our free software and of promoting the sharing
801 and reuse of software generally.
802
803 NO WARRANTY
804
805 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
806 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
807 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
808 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
809 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
810 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
811 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
812 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
813 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
814
815 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
816 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
817 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
818 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
819 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
820 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
821 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
822 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
823 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
824 DAMAGES.
825
826 END OF TERMS AND CONDITIONS
827 \f
828 How to Apply These Terms to Your New Libraries
829
830 If you develop a new library, and you want it to be of the greatest
831 possible use to the public, we recommend making it free software that
832 everyone can redistribute and change. You can do so by permitting
833 redistribution under these terms (or, alternatively, under the terms of the
834 ordinary General Public License).
835
836 To apply these terms, attach the following notices to the library. It is
837 safest to attach them to the start of each source file to most effectively
838 convey the exclusion of warranty; and each file should have at least the
839 "copyright" line and a pointer to where the full notice is found.
840
841 <one line to give the library's name and a brief idea of what it does.>
842 Copyright (C) <year> <name of author>
843
844 This library is free software; you can redistribute it and/or
845 modify it under the terms of the GNU Lesser General Public
846 License as published by the Free Software Foundation; either
847 version 2.1 of the License, or (at your option) any later version.
848
849 This library is distributed in the hope that it will be useful,
850 but WITHOUT ANY WARRANTY; without even the implied warranty of
851 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
852 Lesser General Public License for more details.
853
854 You should have received a copy of the GNU Lesser General Public
855 License along with this library; if not, write to the Free Software
856 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
857
858 Also add information on how to contact you by electronic and paper mail.
859
860 You should also get your employer (if you work as a programmer) or your
861 school, if any, to sign a "copyright disclaimer" for the library, if
862 necessary. Here is a sample; alter the names:
863

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