10 LINKING EXCEPTION
11
12 In addition to the permissions in the GNU General Public License,
13 the authors give you unlimited permission to link the compiled
14 version of this library into combinations with other programs,
15 and to distribute those combinations without any restriction
16 coming from the use of this file. (The General Public License
17 restrictions do apply in other respects; for example, they cover
18 modification of the file, and distribution when not linked into
19 a combined executable.)

26 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
27 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
28 Everyone is permitted to copy and distribute verbatim copies
29 of this license document, but changing it is not allowed.
30
31 Preamble
32
33 The licenses for most software are designed to take away your
34 freedom to share and change it. By contrast, the GNU General Public
35 License is intended to guarantee your freedom to share and change free
36 software--to make sure the software is free for all its users. This
37 General Public License applies to most of the Free Software
38 Foundation's software and to any other program whose authors commit to
39 using it. (Some other Free Software Foundation software is covered by
40 the GNU Library General Public License instead.) You can apply it to
41 your programs, too.
42
43 When we speak of free software, we are referring to freedom, not
44 price. Our General Public Licenses are designed to make sure that you
45 have the freedom to distribute copies of free software (and charge for
46 this service if you wish), that you receive source code or can get it
47 if you want it, that you can change the software or use pieces of it
48 in new free programs; and that you know you can do these things.
49
50 To protect your rights, we need to make restrictions that forbid
51 anyone to deny you these rights or to ask you to surrender the rights.
52 These restrictions translate to certain responsibilities for you if you
53 distribute copies of the software, or if you modify it.
54
55 For example, if you distribute copies of such a program, whether
56 gratis or for a fee, you must give the recipients all the rights that
57 you have. You must make sure that they, too, receive or can get the
58 source code. And you must show them these terms so they know their
59 rights.
60
61 We protect your rights with two steps: (1) copyright the software, and
62 (2) offer you this license which gives you legal permission to copy,
63 distribute and/or modify the software.
64
65 Also, for each author's protection and ours, we want to make certain
66 that everyone understands that there is no warranty for this free
67 software. If the software is modified by someone else and passed on, we
68 want its recipients to know that what they have is not the original, so
69 that any problems introduced by others will not reflect on the original
70 authors' reputations.
71
72 Finally, any free program is threatened constantly by software
73 patents. We wish to avoid the danger that redistributors of a free
74 program will individually obtain patent licenses, in effect making the
75 program proprietary. To prevent this, we have made it clear that any
76 patent must be licensed for everyone's free use or not licensed at all.
77
78 The precise terms and conditions for copying, distribution and
79 modification follow.
80
81 GNU GENERAL PUBLIC LICENSE
82 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
83
84 0. This License applies to any program or other work which contains
85 a notice placed by the copyright holder saying it may be distributed
86 under the terms of this General Public License. The "Program", below,
87 refers to any such program or work, and a "work based on the Program"
88 means either the Program or any derivative work under copyright law:
89 that is to say, a work containing the Program or a portion of it,
90 either verbatim or with modifications and/or translated into another
91 language. (Hereinafter, translation is included without limitation in
92 the term "modification".) Each licensee is addressed as "you".
93
94 Activities other than copying, distribution and modification are not
95 covered by this License; they are outside its scope. The act of
96 running the Program is not restricted, and the output from the Program
97 is covered only if its contents constitute a work based on the
98 Program (independent of having been made by running the Program).
99 Whether that is true depends on what the Program does.
100
101 1. You may copy and distribute verbatim copies of the Program's
102 source code as you receive it, in any medium, provided that you
103 conspicuously and appropriately publish on each copy an appropriate
104 copyright notice and disclaimer of warranty; keep intact all the
105 notices that refer to this License and to the absence of any warranty;
106 and give any other recipients of the Program a copy of this License
107 along with the Program.
108
109 You may charge a fee for the physical act of transferring a copy, and
110 you may at your option offer warranty protection in exchange for a fee.
111
112 2. You may modify your copy or copies of the Program or any portion
113 of it, thus forming a work based on the Program, and copy and
114 distribute such modifications or work under the terms of Section 1
115 above, provided that you also meet all of these conditions:
116
117 a) You must cause the modified files to carry prominent notices
118 stating that you changed the files and the date of any change.
119
120 b) You must cause any work that you distribute or publish, that in
121 whole or in part contains or is derived from the Program or any
122 part thereof, to be licensed as a whole at no charge to all third
123 parties under the terms of this License.
124
125 c) If the modified program normally reads commands interactively
126 when run, you must cause it, when started running for such
127 interactive use in the most ordinary way, to print or display an
128 announcement including an appropriate copyright notice and a
129 notice that there is no warranty (or else, saying that you provide
130 a warranty) and that users may redistribute the program under
131 these conditions, and telling the user how to view a copy of this
132 License. (Exception: if the Program itself is interactive but
133 does not normally print such an announcement, your work based on
134 the Program is not required to print an announcement.)
135
136 These requirements apply to the modified work as a whole. If
137 identifiable sections of that work are not derived from the Program,
138 and can be reasonably considered independent and separate works in
139 themselves, then this License, and its terms, do not apply to those
140 sections when you distribute them as separate works. But when you
141 distribute the same sections as part of a whole which is a work based
142 on the Program, the distribution of the whole must be on the terms of
143 this License, whose permissions for other licensees extend to the
144 entire whole, and thus to each and every part regardless of who wrote it.
145
146 Thus, it is not the intent of this section to claim rights or contest
147 your rights to work written entirely by you; rather, the intent is to
148 exercise the right to control the distribution of derivative or
149 collective works based on the Program.
150
151 In addition, mere aggregation of another work not based on the Program
152 with the Program (or with a work based on the Program) on a volume of
153 a storage or distribution medium does not bring the other work under
154 the scope of this License.
155
156 3. You may copy and distribute the Program (or a work based on it,
157 under Section 2) in object code or executable form under the terms of
158 Sections 1 and 2 above provided that you also do one of the following:
159
160 a) Accompany it with the complete corresponding machine-readable
161 source code, which must be distributed under the terms of Sections
162 1 and 2 above on a medium customarily used for software interchange; or,
163
164 b) Accompany it with a written offer, valid for at least three
165 years, to give any third party, for a charge no more than your
166 cost of physically performing source distribution, a complete
167 machine-readable copy of the corresponding source code, to be
168 distributed under the terms of Sections 1 and 2 above on a medium
169 customarily used for software interchange; or,
170
171 c) Accompany it with the information you received as to the offer
172 to distribute corresponding source code. (This alternative is
173 allowed only for noncommercial distribution and only if you
174 received the program in object code or executable form with such
175 an offer, in accord with Subsection b above.)
176
177 The source code for a work means the preferred form of the work for
178 making modifications to it. For an executable work, complete source
179 code means all the source code for all modules it contains, plus any
180 associated interface definition files, plus the scripts used to
181 control compilation and installation of the executable. However, as a
182 special exception, the source code distributed need not include
183 anything that is normally distributed (in either source or binary
184 form) with the major components (compiler, kernel, and so on) of the
185 operating system on which the executable runs, unless that component
186 itself accompanies the executable.
187
188 If distribution of executable or object code is made by offering
189 access to copy from a designated place, then offering equivalent
190 access to copy the source code from the same place counts as
191 distribution of the source code, even though third parties are not
192 compelled to copy the source along with the object code.
193
194 4. You may not copy, modify, sublicense, or distribute the Program
195 except as expressly provided under this License. Any attempt
196 otherwise to copy, modify, sublicense or distribute the Program is
197 void, and will automatically terminate your rights under this License.
198 However, parties who have received copies, or rights, from you under
199 this License will not have their licenses terminated so long as such
200 parties remain in full compliance.
201
202 5. You are not required to accept this License, since you have not
203 signed it. However, nothing else grants you permission to modify or
204 distribute the Program or its derivative works. These actions are
205 prohibited by law if you do not accept this License. Therefore, by
206 modifying or distributing the Program (or any work based on the
207 Program), you indicate your acceptance of this License to do so, and
208 all its terms and conditions for copying, distributing or modifying
209 the Program or works based on it.
210
211 6. Each time you redistribute the Program (or any work based on the
212 Program), the recipient automatically receives a license from the
213 original licensor to copy, distribute or modify the Program subject to
214 these terms and conditions. You may not impose any further
215 restrictions on the recipients' exercise of the rights granted herein.
216 You are not responsible for enforcing compliance by third parties to
217 this License.
218
219 7. If, as a consequence of a court judgment or allegation of patent
220 infringement or for any other reason (not limited to patent issues),
221 conditions are imposed on you (whether by court order, agreement or
222 otherwise) that contradict the conditions of this License, they do not
223 excuse you from the conditions of this License. If you cannot
224 distribute so as to satisfy simultaneously your obligations under this
225 License and any other pertinent obligations, then as a consequence you
226 may not distribute the Program at all. For example, if a patent
227 license would not permit royalty-free redistribution of the Program by
228 all those who receive copies directly or indirectly through you, then
229 the only way you could satisfy both it and this License would be to
230 refrain entirely from distribution of the Program.
231
232 If any portion of this section is held invalid or unenforceable under
233 any particular circumstance, the balance of the section is intended to
234 apply and the section as a whole is intended to apply in other
235 circumstances.
236
237 It is not the purpose of this section to induce you to infringe any
238 patents or other property right claims or to contest validity of any
239 such claims; this section has the sole purpose of protecting the
240 integrity of the free software distribution system, which is
241 implemented by public license practices. Many people have made
242 generous contributions to the wide range of software distributed
243 through that system in reliance on consistent application of that
244 system; it is up to the author/donor to decide if he or she is willing
245 to distribute software through any other system and a licensee cannot
246 impose that choice.
247
248 This section is intended to make thoroughly clear what is believed to
249 be a consequence of the rest of this License.
250
251 8. If the distribution and/or use of the Program is restricted in
252 certain countries either by patents or by copyrighted interfaces, the
253 original copyright holder who places the Program under this License
254 may add an explicit geographical distribution limitation excluding
255 those countries, so that distribution is permitted only in or among
256 countries not thus excluded. In such case, this License incorporates
257 the limitation as if written in the body of this License.
258
259 9. The Free Software Foundation may publish revised and/or new versions
260 of the General Public License from time to time. Such new versions will
261 be similar in spirit to the present version, but may differ in detail to
262 address new problems or concerns.
263
264 Each version is given a distinguishing version number. If the Program
265 specifies a version number of this License which applies to it and "any
266 later version", you have the option of following the terms and conditions
267 either of that version or of any later version published by the Free
268 Software Foundation. If the Program does not specify a version number of
269 this License, you may choose any version ever published by the Free Software
270 Foundation.
271
272 10. If you wish to incorporate parts of the Program into other free
273 programs whose distribution conditions are different, write to the author
274 to ask for permission. For software which is copyrighted by the Free
275 Software Foundation, write to the Free Software Foundation; we sometimes
276 make exceptions for this. Our decision will be guided by the two goals
277 of preserving the free status of all derivatives of our free software and
278 of promoting the sharing and reuse of software generally.
279
280 NO WARRANTY
281
282 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
283 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
284 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
285 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
286 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
287 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
288 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
289 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
290 REPAIR OR CORRECTION.
291
292 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
293 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
294 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
295 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
296 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
297 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
298 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
299 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
300 POSSIBILITY OF SUCH DAMAGES.
301
302 END OF TERMS AND CONDITIONS
303
304 How to Apply These Terms to Your New Programs
305
306 If you develop a new program, and you want it to be of the greatest
307 possible use to the public, the best way to achieve this is to make it
308 free software which everyone can redistribute and change under these terms.
309
310 To do so, attach the following notices to the program. It is safest
311 to attach them to the start of each source file to most effectively
312 convey the exclusion of warranty; and each file should have at least
313 the "copyright" line and a pointer to where the full notice is found.
314
315 <one line to give the program's name and a brief idea of what it does.>
316 Copyright (C) <year> <name of author>
317
318 This program is free software; you can redistribute it and/or modify
319 it under the terms of the GNU General Public License as published by
320 the Free Software Foundation; either version 2 of the License, or
321 (at your option) any later version.
322
323 This program is distributed in the hope that it will be useful,
324 but WITHOUT ANY WARRANTY; without even the implied warranty of
325 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
326 GNU General Public License for more details.
327
328 You should have received a copy of the GNU General Public License
329 along with this program; if not, write to the Free Software
330 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
331
332
333 Also add information on how to contact you by electronic and paper mail.
334
335 If the program is interactive, make it output a short notice like this
336 when it starts in an interactive mode:
337
338 Gnomovision version 69, Copyright (C) year name of author
339 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
340 This is free software, and you are welcome to redistribute it
341 under certain conditions; type `show c' for details.
342
343 The hypothetical commands `show w' and `show c' should show the appropriate
344 parts of the General Public License. Of course, the commands you use may
345 be called something other than `show w' and `show c'; they could even be
346 mouse-clicks or menu items--whatever suits your program.
347
348 You should also get your employer (if you work as a programmer) or your
349 school, if any, to sign a "copyright disclaimer" for the program, if
350 necessary. Here is a sample; alter the names:
351
352 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
353 `Gnomovision' (which makes passes at compilers) written by James Hacker.

356 Ty Coon, President of Vice
357
358 This General Public License does not permit incorporating your program into
359 proprietary programs. If your program is a subroutine library, you may
360 consider it more useful to permit linking proprietary applications with the
361 library. If this is what you want to do, use the GNU Library General
362 Public License instead of this License.

421 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
422 Everyone is permitted to copy and distribute verbatim copies
423 of this license document, but changing it is not allowed.
424
425 [This is the first released version of the Lesser GPL. It also counts
426 as the successor of the GNU Library Public License, version 2, hence
427 the version number 2.1.]
428
429 Preamble
430
431 The licenses for most software are designed to take away your
432 freedom to share and change it. By contrast, the GNU General Public
433 Licenses are intended to guarantee your freedom to share and change
434 free software--to make sure the software is free for all its users.
435
436 This license, the Lesser General Public License, applies to some
437 specially designated software packages--typically libraries--of the
438 Free Software Foundation and other authors who decide to use it. You
439 can use it too, but we suggest you first think carefully about whether
440 this license or the ordinary General Public License is the better
441 strategy to use in any particular case, based on the explanations below.
442
443 When we speak of free software, we are referring to freedom of use,
444 not price. Our General Public Licenses are designed to make sure that
445 you have the freedom to distribute copies of free software (and charge
446 for this service if you wish); that you receive source code or can get
447 it if you want it; that you can change the software and use pieces of
448 it in new free programs; and that you are informed that you can do
449 these things.
450
451 To protect your rights, we need to make restrictions that forbid
452 distributors to deny you these rights or to ask you to surrender these
453 rights. These restrictions translate to certain responsibilities for
454 you if you distribute copies of the library or if you modify it.
455
456 For example, if you distribute copies of the library, whether gratis
457 or for a fee, you must give the recipients all the rights that we gave
458 you. You must make sure that they, too, receive or can get the source
459 code. If you link other code with the library, you must provide
460 complete object files to the recipients, so that they can relink them
461 with the library after making changes to the library and recompiling
462 it. And you must show them these terms so they know their rights.
463
464 We protect your rights with a two-step method: (1) we copyright the
465 library, and (2) we offer you this license, which gives you legal
466 permission to copy, distribute and/or modify the library.
467
468 To protect each distributor, we want to make it very clear that
469 there is no warranty for the free library. Also, if the library is
470 modified by someone else and passed on, the recipients should know
471 that what they have is not the original version, so that the original
472 author's reputation will not be affected by problems that might be
473 introduced by others.
474 \f
475 Finally, software patents pose a constant threat to the existence of
476 any free program. We wish to make sure that a company cannot
477 effectively restrict the users of a free program by obtaining a
478 restrictive license from a patent holder. Therefore, we insist that
479 any patent license obtained for a version of the library must be
480 consistent with the full freedom of use specified in this license.
481
482 Most GNU software, including some libraries, is covered by the
483 ordinary GNU General Public License. This license, the GNU Lesser
484 General Public License, applies to certain designated libraries, and
485 is quite different from the ordinary General Public License. We use
486 this license for certain libraries in order to permit linking those
487 libraries into non-free programs.
488
489 When a program is linked with a library, whether statically or using
490 a shared library, the combination of the two is legally speaking a
491 combined work, a derivative of the original library. The ordinary
492 General Public License therefore permits such linking only if the
493 entire combination fits its criteria of freedom. The Lesser General
494 Public License permits more lax criteria for linking other code with
495 the library.
496
497 We call this license the "Lesser" General Public License because it
498 does Less to protect the user's freedom than the ordinary General
499 Public License. It also provides other free software developers Less
500 of an advantage over competing non-free programs. These disadvantages
501 are the reason we use the ordinary General Public License for many
502 libraries. However, the Lesser license provides advantages in certain
503 special circumstances.
504
505 For example, on rare occasions, there may be a special need to
506 encourage the widest possible use of a certain library, so that it becomes
507 a de-facto standard. To achieve this, non-free programs must be
508 allowed to use the library. A more frequent case is that a free
509 library does the same job as widely used non-free libraries. In this
510 case, there is little to gain by limiting the free library to free
511 software only, so we use the Lesser General Public License.
512
513 In other cases, permission to use a particular library in non-free
514 programs enables a greater number of people to use a large body of
515 free software. For example, permission to use the GNU C Library in
516 non-free programs enables many more people to use the whole GNU
517 operating system, as well as its variant, the GNU/Linux operating
518 system.
519
520 Although the Lesser General Public License is Less protective of the
521 users' freedom, it does ensure that the user of a program that is
522 linked with the Library has the freedom and the wherewithal to run
523 that program using a modified version of the Library.
524
525 The precise terms and conditions for copying, distribution and
526 modification follow. Pay close attention to the difference between a
527 "work based on the library" and a "work that uses the library". The
528 former contains code derived from the library, whereas the latter must
529 be combined with the library in order to run.
530 \f
531 GNU LESSER GENERAL PUBLIC LICENSE
532 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
533
534 0. This License Agreement applies to any software library or other
535 program which contains a notice placed by the copyright holder or
536 other authorized party saying it may be distributed under the terms of
537 this Lesser General Public License (also called "this License").
538 Each licensee is addressed as "you".
539
540 A "library" means a collection of software functions and/or data
541 prepared so as to be conveniently linked with application programs
542 (which use some of those functions and data) to form executables.
543
544 The "Library", below, refers to any such software library or work
545 which has been distributed under these terms. A "work based on the
546 Library" means either the Library or any derivative work under
547 copyright law: that is to say, a work containing the Library or a
548 portion of it, either verbatim or with modifications and/or translated
549 straightforwardly into another language. (Hereinafter, translation is
550 included without limitation in the term "modification".)
551
552 "Source code" for a work means the preferred form of the work for
553 making modifications to it. For a library, complete source code means
554 all the source code for all modules it contains, plus any associated
555 interface definition files, plus the scripts used to control compilation
556 and installation of the library.
557
558 Activities other than copying, distribution and modification are not
559 covered by this License; they are outside its scope. The act of
560 running a program using the Library is not restricted, and output from
561 such a program is covered only if its contents constitute a work based
562 on the Library (independent of the use of the Library in a tool for
563 writing it). Whether that is true depends on what the Library does
564 and what the program that uses the Library does.
565
566 1. You may copy and distribute verbatim copies of the Library's
567 complete source code as you receive it, in any medium, provided that
568 you conspicuously and appropriately publish on each copy an
569 appropriate copyright notice and disclaimer of warranty; keep intact
570 all the notices that refer to this License and to the absence of any
571 warranty; and distribute a copy of this License along with the
572 Library.
573
574 You may charge a fee for the physical act of transferring a copy,
575 and you may at your option offer warranty protection in exchange for a
576 fee.
577 \f
578 2. You may modify your copy or copies of the Library or any portion
579 of it, thus forming a work based on the Library, and copy and
580 distribute such modifications or work under the terms of Section 1
581 above, provided that you also meet all of these conditions:
582
583 a) The modified work must itself be a software library.
584
585 b) You must cause the files modified to carry prominent notices
586 stating that you changed the files and the date of any change.
587
588 c) You must cause the whole of the work to be licensed at no
589 charge to all third parties under the terms of this License.
590
591 d) If a facility in the modified Library refers to a function or a
592 table of data to be supplied by an application program that uses
593 the facility, other than as an argument passed when the facility
594 is invoked, then you must make a good faith effort to ensure that,
595 in the event an application does not supply such function or
596 table, the facility still operates, and performs whatever part of
597 its purpose remains meaningful.
598
599 (For example, a function in a library to compute square roots has
600 a purpose that is entirely well-defined independent of the
601 application. Therefore, Subsection 2d requires that any
602 application-supplied function or table used by this function must
603 be optional: if the application does not supply it, the square
604 root function must still compute square roots.)
605
606 These requirements apply to the modified work as a whole. If
607 identifiable sections of that work are not derived from the Library,
608 and can be reasonably considered independent and separate works in
609 themselves, then this License, and its terms, do not apply to those
610 sections when you distribute them as separate works. But when you
611 distribute the same sections as part of a whole which is a work based
612 on the Library, the distribution of the whole must be on the terms of
613 this License, whose permissions for other licensees extend to the
614 entire whole, and thus to each and every part regardless of who wrote
615 it.
616
617 Thus, it is not the intent of this section to claim rights or contest
618 your rights to work written entirely by you; rather, the intent is to
619 exercise the right to control the distribution of derivative or
620 collective works based on the Library.
621
622 In addition, mere aggregation of another work not based on the Library
623 with the Library (or with a work based on the Library) on a volume of
624 a storage or distribution medium does not bring the other work under
625 the scope of this License.
626
627 3. You may opt to apply the terms of the ordinary GNU General Public
628 License instead of this License to a given copy of the Library. To do
629 this, you must alter all the notices that refer to this License, so
630 that they refer to the ordinary GNU General Public License, version 2,
631 instead of to this License. (If a newer version than version 2 of the
632 ordinary GNU General Public License has appeared, then you can specify
633 that version instead if you wish.) Do not make any other change in
634 these notices.
635 \f
636 Once this change is made in a given copy, it is irreversible for
637 that copy, so the ordinary GNU General Public License applies to all
638 subsequent copies and derivative works made from that copy.
639
640 This option is useful when you wish to copy part of the code of
641 the Library into a program that is not a library.
642
643 4. You may copy and distribute the Library (or a portion or
644 derivative of it, under Section 2) in object code or executable form
645 under the terms of Sections 1 and 2 above provided that you accompany
646 it with the complete corresponding machine-readable source code, which
647 must be distributed under the terms of Sections 1 and 2 above on a
648 medium customarily used for software interchange.
649
650 If distribution of object code is made by offering access to copy
651 from a designated place, then offering equivalent access to copy the
652 source code from the same place satisfies the requirement to
653 distribute the source code, even though third parties are not
654 compelled to copy the source along with the object code.
655
656 5. A program that contains no derivative of any portion of the
657 Library, but is designed to work with the Library by being compiled or
658 linked with it, is called a "work that uses the Library". Such a
659 work, in isolation, is not a derivative work of the Library, and
660 therefore falls outside the scope of this License.
661
662 However, linking a "work that uses the Library" with the Library
663 creates an executable that is a derivative of the Library (because it
664 contains portions of the Library), rather than a "work that uses the
665 library". The executable is therefore covered by this License.
666 Section 6 states terms for distribution of such executables.
667
668 When a "work that uses the Library" uses material from a header file
669 that is part of the Library, the object code for the work may be a
670 derivative work of the Library even though the source code is not.
671 Whether this is true is especially significant if the work can be
672 linked without the Library, or if the work is itself a library. The
673 threshold for this to be true is not precisely defined by law.
674
675 If such an object file uses only numerical parameters, data
676 structure layouts and accessors, and small macros and small inline
677 functions (ten lines or less in length), then the use of the object
678 file is unrestricted, regardless of whether it is legally a derivative
679 work. (Executables containing this object code plus portions of the
680 Library will still fall under Section 6.)
681
682 Otherwise, if the work is a derivative of the Library, you may
683 distribute the object code for the work under the terms of Section 6.
684 Any executables containing that work also fall under Section 6,
685 whether or not they are linked directly with the Library itself.
686 \f
687 6. As an exception to the Sections above, you may also combine or
688 link a "work that uses the Library" with the Library to produce a
689 work containing portions of the Library, and distribute that work
690 under terms of your choice, provided that the terms permit
691 modification of the work for the customer's own use and reverse
692 engineering for debugging such modifications.
693
694 You must give prominent notice with each copy of the work that the
695 Library is used in it and that the Library and its use are covered by
696 this License. You must supply a copy of this License. If the work
697 during execution displays copyright notices, you must include the
698 copyright notice for the Library among them, as well as a reference
699 directing the user to the copy of this License. Also, you must do one
700 of these things:
701
702 a) Accompany the work with the complete corresponding
703 machine-readable source code for the Library including whatever
704 changes were used in the work (which must be distributed under
705 Sections 1 and 2 above); and, if the work is an executable linked
706 with the Library, with the complete machine-readable "work that
707 uses the Library", as object code and/or source code, so that the
708 user can modify the Library and then relink to produce a modified
709 executable containing the modified Library. (It is understood
710 that the user who changes the contents of definitions files in the
711 Library will not necessarily be able to recompile the application
712 to use the modified definitions.)
713
714 b) Use a suitable shared library mechanism for linking with the
715 Library. A suitable mechanism is one that (1) uses at run time a
716 copy of the library already present on the user's computer system,
717 rather than copying library functions into the executable, and (2)
718 will operate properly with a modified version of the library, if
719 the user installs one, as long as the modified version is
720 interface-compatible with the version that the work was made with.
721
722 c) Accompany the work with a written offer, valid for at
723 least three years, to give the same user the materials
724 specified in Subsection 6a, above, for a charge no more
725 than the cost of performing this distribution.
726
727 d) If distribution of the work is made by offering access to copy
728 from a designated place, offer equivalent access to copy the above
729 specified materials from the same place.
730
731 e) Verify that the user has already received a copy of these
732 materials or that you have already sent this user a copy.
733
734 For an executable, the required form of the "work that uses the
735 Library" must include any data and utility programs needed for
736 reproducing the executable from it. However, as a special exception,
737 the materials to be distributed need not include anything that is
738 normally distributed (in either source or binary form) with the major
739 components (compiler, kernel, and so on) of the operating system on
740 which the executable runs, unless that component itself accompanies
741 the executable.
742
743 It may happen that this requirement contradicts the license
744 restrictions of other proprietary libraries that do not normally
745 accompany the operating system. Such a contradiction means you cannot
746 use both them and the Library together in an executable that you
747 distribute.
748 \f
749 7. You may place library facilities that are a work based on the
750 Library side-by-side in a single library together with other library
751 facilities not covered by this License, and distribute such a combined
752 library, provided that the separate distribution of the work based on
753 the Library and of the other library facilities is otherwise
754 permitted, and provided that you do these two things:
755
756 a) Accompany the combined library with a copy of the same work
757 based on the Library, uncombined with any other library
758 facilities. This must be distributed under the terms of the
759 Sections above.
760
761 b) Give prominent notice with the combined library of the fact
762 that part of it is a work based on the Library, and explaining
763 where to find the accompanying uncombined form of the same work.
764
765 8. You may not copy, modify, sublicense, link with, or distribute
766 the Library except as expressly provided under this License. Any
767 attempt otherwise to copy, modify, sublicense, link with, or
768 distribute the Library is void, and will automatically terminate your
769 rights under this License. However, parties who have received copies,
770 or rights, from you under this License will not have their licenses
771 terminated so long as such parties remain in full compliance.
772
773 9. You are not required to accept this License, since you have not
774 signed it. However, nothing else grants you permission to modify or
775 distribute the Library or its derivative works. These actions are
776 prohibited by law if you do not accept this License. Therefore, by
777 modifying or distributing the Library (or any work based on the
778 Library), you indicate your acceptance of this License to do so, and
779 all its terms and conditions for copying, distributing or modifying
780 the Library or works based on it.
781
782 10. Each time you redistribute the Library (or any work based on the
783 Library), the recipient automatically receives a license from the
784 original licensor to copy, distribute, link with or modify the Library
785 subject to these terms and conditions. You may not impose any further
786 restrictions on the recipients' exercise of the rights granted herein.
787 You are not responsible for enforcing compliance by third parties with
788 this License.
789 \f
790 11. If, as a consequence of a court judgment or allegation of patent
791 infringement or for any other reason (not limited to patent issues),
792 conditions are imposed on you (whether by court order, agreement or
793 otherwise) that contradict the conditions of this License, they do not
794 excuse you from the conditions of this License. If you cannot
795 distribute so as to satisfy simultaneously your obligations under this
796 License and any other pertinent obligations, then as a consequence you
797 may not distribute the Library at all. For example, if a patent
798 license would not permit royalty-free redistribution of the Library by
799 all those who receive copies directly or indirectly through you, then
800 the only way you could satisfy both it and this License would be to
801 refrain entirely from distribution of the Library.
802
803 If any portion of this section is held invalid or unenforceable under any
804 particular circumstance, the balance of the section is intended to apply,
805 and the section as a whole is intended to apply in other circumstances.
806
807 It is not the purpose of this section to induce you to infringe any
808 patents or other property right claims or to contest validity of any
809 such claims; this section has the sole purpose of protecting the
810 integrity of the free software distribution system which is
811 implemented by public license practices. Many people have made
812 generous contributions to the wide range of software distributed
813 through that system in reliance on consistent application of that
814 system; it is up to the author/donor to decide if he or she is willing
815 to distribute software through any other system and a licensee cannot
816 impose that choice.
817
818 This section is intended to make thoroughly clear what is believed to
819 be a consequence of the rest of this License.
820
821 12. If the distribution and/or use of the Library is restricted in
822 certain countries either by patents or by copyrighted interfaces, the
823 original copyright holder who places the Library under this License may add
824 an explicit geographical distribution limitation excluding those countries,
825 so that distribution is permitted only in or among countries not thus
826 excluded. In such case, this License incorporates the limitation as if
827 written in the body of this License.
828
829 13. The Free Software Foundation may publish revised and/or new
830 versions of the Lesser General Public License from time to time.
831 Such new versions will be similar in spirit to the present version,
832 but may differ in detail to address new problems or concerns.
833
834 Each version is given a distinguishing version number. If the Library
835 specifies a version number of this License which applies to it and
836 "any later version", you have the option of following the terms and
837 conditions either of that version or of any later version published by
838 the Free Software Foundation. If the Library does not specify a
839 license version number, you may choose any version ever published by
840 the Free Software Foundation.
841 \f
842 14. If you wish to incorporate parts of the Library into other free
843 programs whose distribution conditions are incompatible with these,
844 write to the author to ask for permission. For software which is
845 copyrighted by the Free Software Foundation, write to the Free
846 Software Foundation; we sometimes make exceptions for this. Our
847 decision will be guided by the two goals of preserving the free status
848 of all derivatives of our free software and of promoting the sharing
849 and reuse of software generally.
850
851 NO WARRANTY
852
853 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
854 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
855 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
856 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
857 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
858 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
859 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
860 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
861 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
862
863 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
864 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
865 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
866 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
867 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
868 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
869 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
870 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
871 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
872 DAMAGES.
873
874 END OF TERMS AND CONDITIONS
875 \f
876 How to Apply These Terms to Your New Libraries
877
878 If you develop a new library, and you want it to be of the greatest
879 possible use to the public, we recommend making it free software that
880 everyone can redistribute and change. You can do so by permitting
881 redistribution under these terms (or, alternatively, under the terms of the
882 ordinary General Public License).
883
884 To apply these terms, attach the following notices to the library. It is
885 safest to attach them to the start of each source file to most effectively
886 convey the exclusion of warranty; and each file should have at least the
887 "copyright" line and a pointer to where the full notice is found.
888
889 <one line to give the library's name and a brief idea of what it does.>
890 Copyright (C) <year> <name of author>
891
892 This library is free software; you can redistribute it and/or
893 modify it under the terms of the GNU Lesser General Public
894 License as published by the Free Software Foundation; either
895 version 2.1 of the License, or (at your option) any later version.
896
897 This library is distributed in the hope that it will be useful,
898 but WITHOUT ANY WARRANTY; without even the implied warranty of
899 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
900 Lesser General Public License for more details.
901
902 You should have received a copy of the GNU Lesser General Public
903 License along with this library; if not, write to the Free Software
904 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
905
906 Also add information on how to contact you by electronic and paper mail.
907
908 You should also get your employer (if you work as a programmer) or your
909 school, if any, to sign a "copyright disclaimer" for the library, if
910 necessary. Here is a sample; alter the names:
911
