sell support for the software.
107
What this license *does not* allow you to do is make changes or add
108
features to the software and then sell a binary distribution without

the software, and all code must be provided under the GPL or LGPL as

126
Everyone is permitted to copy and distribute verbatim copies
127
of this license document, but changing it is not allowed.
131
The licenses for most software are designed to take away your
132
freedom to share and change it. By contrast, the GNU General Public
133
License is intended to guarantee your freedom to share and change free
134
software--to make sure the software is free for all its users. This
135
General Public License applies to most of the Free Software
136
Foundation's software and to any other program whose authors commit to
137
using it. (Some other Free Software Foundation software is covered by
138
the GNU Library General Public License instead.) You can apply it to
141
When we speak of free software, we are referring to freedom, not
142
price. Our General Public Licenses are designed to make sure that you
143
have the freedom to distribute copies of free software (and charge for
144
this service if you wish), that you receive source code or can get it
145
if you want it, that you can change the software or use pieces of it
146
in new free programs; and that you know you can do these things.
148
To protect your rights, we need to make restrictions that forbid
149
anyone to deny you these rights or to ask you to surrender the rights.
150
These restrictions translate to certain responsibilities for you if you
151
distribute copies of the software, or if you modify it.
153
For example, if you distribute copies of such a program, whether
154
gratis or for a fee, you must give the recipients all the rights that
155
you have. You must make sure that they, too, receive or can get the
156
source code. And you must show them these terms so they know their
159
We protect your rights with two steps: (1) copyright the software, and
160
(2) offer you this license which gives you legal permission to copy,
161
distribute and/or modify the software.
163
Also, for each author's protection and ours, we want to make certain
164
that everyone understands that there is no warranty for this free
165
software. If the software is modified by someone else and passed on, we
166
want its recipients to know that what they have is not the original, so
167
that any problems introduced by others will not reflect on the original
168
authors' reputations.
170
Finally, any free program is threatened constantly by software
171
patents. We wish to avoid the danger that redistributors of a free
172
program will individually obtain patent licenses, in effect making the
173
program proprietary. To prevent this, we have made it clear that any
174
patent must be licensed for everyone's free use or not licensed at all.
176
The precise terms and conditions for copying, distribution and
179
GNU GENERAL PUBLIC LICENSE
180
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
182
0. This License applies to any program or other work which contains
183
a notice placed by the copyright holder saying it may be distributed
184
under the terms of this General Public License. The "Program", below,
185
refers to any such program or work, and a "work based on the Program"
186
means either the Program or any derivative work under copyright law:
187
that is to say, a work containing the Program or a portion of it,
188
either verbatim or with modifications and/or translated into another
189
language. (Hereinafter, translation is included without limitation in
190
the term "modification".) Each licensee is addressed as "you".
192
Activities other than copying, distribution and modification are not
193
covered by this License; they are outside its scope. The act of
194
running the Program is not restricted, and the output from the Program
195
is covered only if its contents constitute a work based on the
196
Program (independent of having been made by running the Program).
197
Whether that is true depends on what the Program does.
199
1. You may copy and distribute verbatim copies of the Program's
200
source code as you receive it, in any medium, provided that you
201
conspicuously and appropriately publish on each copy an appropriate
202
copyright notice and disclaimer of warranty; keep intact all the
203
notices that refer to this License and to the absence of any warranty;
204
and give any other recipients of the Program a copy of this License
205
along with the Program.
207
You may charge a fee for the physical act of transferring a copy, and
208
you may at your option offer warranty protection in exchange for a fee.
210
2. You may modify your copy or copies of the Program or any portion
211
of it, thus forming a work based on the Program, and copy and
212
distribute such modifications or work under the terms of Section 1
213
above, provided that you also meet all of these conditions:
215
a) You must cause the modified files to carry prominent notices
216
stating that you changed the files and the date of any change.
218
b) You must cause any work that you distribute or publish, that in
219
whole or in part contains or is derived from the Program or any
220
part thereof, to be licensed as a whole at no charge to all third
221
parties under the terms of this License.
223
c) If the modified program normally reads commands interactively
224
when run, you must cause it, when started running for such
225
interactive use in the most ordinary way, to print or display an
226
announcement including an appropriate copyright notice and a
227
notice that there is no warranty (or else, saying that you provide
228
a warranty) and that users may redistribute the program under
229
these conditions, and telling the user how to view a copy of this
230
License. (Exception: if the Program itself is interactive but
231
does not normally print such an announcement, your work based on
232
the Program is not required to print an announcement.)
234
These requirements apply to the modified work as a whole. If
235
identifiable sections of that work are not derived from the Program,
236
and can be reasonably considered independent and separate works in
237
themselves, then this License, and its terms, do not apply to those
238
sections when you distribute them as separate works. But when you
239
distribute the same sections as part of a whole which is a work based
240
on the Program, the distribution of the whole must be on the terms of
241
this License, whose permissions for other licensees extend to the
242
entire whole, and thus to each and every part regardless of who wrote it.
244
Thus, it is not the intent of this section to claim rights or contest
245
your rights to work written entirely by you; rather, the intent is to
246
exercise the right to control the distribution of derivative or
247
collective works based on the Program.
249
In addition, mere aggregation of another work not based on the Program
250
with the Program (or with a work based on the Program) on a volume of
251
a storage or distribution medium does not bring the other work under
252
the scope of this License.
254
3. You may copy and distribute the Program (or a work based on it,
255
under Section 2) in object code or executable form under the terms of
256
Sections 1 and 2 above provided that you also do one of the following:
258
a) Accompany it with the complete corresponding machine-readable
259
source code, which must be distributed under the terms of Sections
260
1 and 2 above on a medium customarily used for software interchange; or,
262
b) Accompany it with a written offer, valid for at least three
263
years, to give any third party, for a charge no more than your
264
cost of physically performing source distribution, a complete
265
machine-readable copy of the corresponding source code, to be
266
distributed under the terms of Sections 1 and 2 above on a medium
267
customarily used for software interchange; or,
269
c) Accompany it with the information you received as to the offer
270
to distribute corresponding source code. (This alternative is
271
allowed only for noncommercial distribution and only if you
272
received the program in object code or executable form with such
273
an offer, in accord with Subsection b above.)
275
The source code for a work means the preferred form of the work for
276
making modifications to it. For an executable work, complete source
277
code means all the source code for all modules it contains, plus any
278
associated interface definition files, plus the scripts used to
279
control compilation and installation of the executable. However, as a
280
special exception, the source code distributed need not include
281
anything that is normally distributed (in either source or binary
282
form) with the major components (compiler, kernel, and so on) of the
283
operating system on which the executable runs, unless that component
284
itself accompanies the executable.
286
If distribution of executable or object code is made by offering
287
access to copy from a designated place, then offering equivalent
288
access to copy the source code from the same place counts as
289
distribution of the source code, even though third parties are not
290
compelled to copy the source along with the object code.
292
4. You may not copy, modify, sublicense, or distribute the Program
293
except as expressly provided under this License. Any attempt
294
otherwise to copy, modify, sublicense or distribute the Program is
295
void, and will automatically terminate your rights under this License.
296
However, parties who have received copies, or rights, from you under
297
this License will not have their licenses terminated so long as such
298
parties remain in full compliance.
300
5. You are not required to accept this License, since you have not
301
signed it. However, nothing else grants you permission to modify or
302
distribute the Program or its derivative works. These actions are
303
prohibited by law if you do not accept this License. Therefore, by
304
modifying or distributing the Program (or any work based on the
305
Program), you indicate your acceptance of this License to do so, and
306
all its terms and conditions for copying, distributing or modifying
307
the Program or works based on it.
309
6. Each time you redistribute the Program (or any work based on the
310
Program), the recipient automatically receives a license from the
311
original licensor to copy, distribute or modify the Program subject to
312
these terms and conditions. You may not impose any further
313
restrictions on the recipients' exercise of the rights granted herein.
314
You are not responsible for enforcing compliance by third parties to
317
7. If, as a consequence of a court judgment or allegation of patent
318
infringement or for any other reason (not limited to patent issues),
319
conditions are imposed on you (whether by court order, agreement or
320
otherwise) that contradict the conditions of this License, they do not
321
excuse you from the conditions of this License. If you cannot
322
distribute so as to satisfy simultaneously your obligations under this
323
License and any other pertinent obligations, then as a consequence you
324
may not distribute the Program at all. For example, if a patent
325
license would not permit royalty-free redistribution of the Program by
326
all those who receive copies directly or indirectly through you, then
327
the only way you could satisfy both it and this License would be to
328
refrain entirely from distribution of the Program.
330
If any portion of this section is held invalid or unenforceable under
331
any particular circumstance, the balance of the section is intended to
332
apply and the section as a whole is intended to apply in other
335
It is not the purpose of this section to induce you to infringe any
336
patents or other property right claims or to contest validity of any
337
such claims; this section has the sole purpose of protecting the
338
integrity of the free software distribution system, which is
339
implemented by public license practices. Many people have made
340
generous contributions to the wide range of software distributed
341
through that system in reliance on consistent application of that
342
system; it is up to the author/donor to decide if he or she is willing
343
to distribute software through any other system and a licensee cannot
346
This section is intended to make thoroughly clear what is believed to
347
be a consequence of the rest of this License.
349
8. If the distribution and/or use of the Program is restricted in
350
certain countries either by patents or by copyrighted interfaces, the
351
original copyright holder who places the Program under this License
352
may add an explicit geographical distribution limitation excluding
353
those countries, so that distribution is permitted only in or among
354
countries not thus excluded. In such case, this License incorporates
355
the limitation as if written in the body of this License.
357
9. The Free Software Foundation may publish revised and/or new versions
358
of the General Public License from time to time. Such new versions will
359
be similar in spirit to the present version, but may differ in detail to
360
address new problems or concerns.
362
Each version is given a distinguishing version number. If the Program
363
specifies a version number of this License which applies to it and "any
364
later version", you have the option of following the terms and conditions
365
either of that version or of any later version published by the Free
366
Software Foundation. If the Program does not specify a version number of
367
this License, you may choose any version ever published by the Free Software
370
10. If you wish to incorporate parts of the Program into other free
371
programs whose distribution conditions are different, write to the author
372
to ask for permission. For software which is copyrighted by the Free
373
Software Foundation, write to the Free Software Foundation; we sometimes
374
make exceptions for this. Our decision will be guided by the two goals
375
of preserving the free status of all derivatives of our free software and
376
of promoting the sharing and reuse of software generally.
380
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
381
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
382
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
383
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
384
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
385
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
386
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
387
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
388
REPAIR OR CORRECTION.
390
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
391
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
392
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
393
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
394
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
395
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
396
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
397
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
398
POSSIBILITY OF SUCH DAMAGES.
400
END OF TERMS AND CONDITIONS
402
Appendix: How to Apply These Terms to Your New Programs
404
If you develop a new program, and you want it to be of the greatest
405
possible use to the public, the best way to achieve this is to make it
406
free software which everyone can redistribute and change under these terms.
408
To do so, attach the following notices to the program. It is safest
409
to attach them to the start of each source file to most effectively
410
convey the exclusion of warranty; and each file should have at least
411
the "copyright" line and a pointer to where the full notice is found.
413
<one line to give the program's name and a brief idea of what it does.>
414
Copyright (C) 19yy <name of author>
416
This program is free software; you can redistribute it and/or modify
417
it under the terms of the GNU General Public License as published by
418
the Free Software Foundation; either version 2 of the License, or
419
(at your option) any later version.
421
This program is distributed in the hope that it will be useful,
422
but WITHOUT ANY WARRANTY; without even the implied warranty of
423
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
424
GNU General Public License for more details.
426
You should have received a copy of the GNU General Public License
427
along with this program; if not, write to the Free Software
428
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
430
Also add information on how to contact you by electronic and paper mail.
432
If the program is interactive, make it output a short notice like this
433
when it starts in an interactive mode:
435
Gnomovision version 69, Copyright (C) 19yy name of author
436
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
437
This is free software, and you are welcome to redistribute it
438
under certain conditions; type `show c' for details.
440
The hypothetical commands `show w' and `show c' should show the appropriate
441
parts of the General Public License. Of course, the commands you use may
442
be called something other than `show w' and `show c'; they could even be
443
mouse-clicks or menu items--whatever suits your program.
445
You should also get your employer (if you work as a programmer) or your
446
school, if any, to sign a "copyright disclaimer" for the program, if
447
necessary. Here is a sample; alter the names:
449
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

This General Public License does not permit incorporating your program into
456
proprietary programs. If your program is a subroutine library, you may
457
consider it more useful to permit linking proprietary applications with the
458
library. If this is what you want to do, use the GNU Library General
459
Public License instead of this License.

GNU LIBRARY GENERAL PUBLIC LICENSE

Copyright (C) 1991 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
467
Everyone is permitted to copy and distribute verbatim copies
468
of this license document, but changing it is not allowed.
470
[This is the first released version of the library GPL. It is
471
numbered 2 because it goes with version 2 of the ordinary GPL.]
475
The licenses for most software are designed to take away your
476
freedom to share and change it. By contrast, the GNU General Public
477
Licenses are intended to guarantee your freedom to share and change
478
free software--to make sure the software is free for all its users.
480
This license, the Library General Public License, applies to some
481
specially designated Free Software Foundation software, and to any
482
other libraries whose authors decide to use it. You can use it for
485
When we speak of free software, we are referring to freedom, not
486
price. Our General Public Licenses are designed to make sure that you
487
have the freedom to distribute copies of free software (and charge for
488
this service if you wish), that you receive source code or can get it
489
if you want it, that you can change the software or use pieces of it
490
in new free programs; and that you know you can do these things.
492
To protect your rights, we need to make restrictions that forbid
493
anyone to deny you these rights or to ask you to surrender the rights.
494
These restrictions translate to certain responsibilities for you if
495
you distribute copies of the library, or if you modify it.
497
For example, if you distribute copies of the library, whether gratis
498
or for a fee, you must give the recipients all the rights that we gave
499
you. You must make sure that they, too, receive or can get the source
500
code. If you link a program with the library, you must provide
501
complete object files to the recipients so that they can relink them
502
with the library, after making changes to the library and recompiling
503
it. And you must show them these terms so they know their rights.
505
Our method of protecting your rights has two steps: (1) copyright
506
the library, and (2) offer you this license which gives you legal
507
permission to copy, distribute and/or modify the library.
509
Also, for each distributor's protection, we want to make certain
510
that everyone understands that there is no warranty for this free
511
library. If the library is modified by someone else and passed on, we
512
want its recipients to know that what they have is not the original
513
version, so that any problems introduced by others will not reflect on
514
the original authors' reputations.
516
Finally, any free program is threatened constantly by software
517
patents. We wish to avoid the danger that companies distributing free
518
software will individually obtain patent licenses, thus in effect
519
transforming the program into proprietary software. To prevent this,
520
we have made it clear that any patent must be licensed for everyone's
521
free use or not licensed at all.
523
Most GNU software, including some libraries, is covered by the ordinary
524
GNU General Public License, which was designed for utility programs. This
525
license, the GNU Library General Public License, applies to certain
526
designated libraries. This license is quite different from the ordinary
527
one; be sure to read it in full, and don't assume that anything in it is
528
the same as in the ordinary license.
530
The reason we have a separate public license for some libraries is that
531
they blur the distinction we usually make between modifying or adding to a
532
program and simply using it. Linking a program with a library, without
533
changing the library, is in some sense simply using the library, and is
534
analogous to running a utility program or application program. However, in
535
a textual and legal sense, the linked executable is a combined work, a
536
derivative of the original library, and the ordinary General Public License
539
Because of this blurred distinction, using the ordinary General
540
Public License for libraries did not effectively promote software
541
sharing, because most developers did not use the libraries. We
542
concluded that weaker conditions might promote sharing better.
544
However, unrestricted linking of non-free programs would deprive the
545
users of those programs of all benefit from the free status of the
546
libraries themselves. This Library General Public License is intended to
547
permit developers of non-free programs to use free libraries, while
548
preserving your freedom as a user of such programs to change the free
549
libraries that are incorporated in them. (We have not seen how to achieve
550
this as regards changes in header files, but we have achieved it as regards
551
changes in the actual functions of the Library.) The hope is that this
552
will lead to faster development of free libraries.
554
The precise terms and conditions for copying, distribution and
555
modification follow. Pay close attention to the difference between a
556
"work based on the library" and a "work that uses the library". The
557
former contains code derived from the library, while the latter only
558
works together with the library.
560
Note that it is possible for a library to be covered by the ordinary
561
General Public License rather than by this special one.
563
GNU LIBRARY GENERAL PUBLIC LICENSE
564
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
566
0. This License Agreement applies to any software library which
567
contains a notice placed by the copyright holder or other authorized
568
party saying it may be distributed under the terms of this Library
569
General Public License (also called "this License"). Each licensee is
572
A "library" means a collection of software functions and/or data
573
prepared so as to be conveniently linked with application programs
574
(which use some of those functions and data) to form executables.
576
The "Library", below, refers to any such software library or work
577
which has been distributed under these terms. A "work based on the
578
Library" means either the Library or any derivative work under
579
copyright law: that is to say, a work containing the Library or a
580
portion of it, either verbatim or with modifications and/or translated
581
straightforwardly into another language. (Hereinafter, translation is
582
included without limitation in the term "modification".)
584
"Source code" for a work means the preferred form of the work for
585
making modifications to it. For a library, complete source code means
586
all the source code for all modules it contains, plus any associated
587
interface definition files, plus the scripts used to control compilation
588
and installation of the library.
590
Activities other than copying, distribution and modification are not
591
covered by this License; they are outside its scope. The act of
592
running a program using the Library is not restricted, and output from
593
such a program is covered only if its contents constitute a work based
594
on the Library (independent of the use of the Library in a tool for
595
writing it). Whether that is true depends on what the Library does
596
and what the program that uses the Library does.
598
1. You may copy and distribute verbatim copies of the Library's
599
complete source code as you receive it, in any medium, provided that
600
you conspicuously and appropriately publish on each copy an
601
appropriate copyright notice and disclaimer of warranty; keep intact
602
all the notices that refer to this License and to the absence of any
603
warranty; and distribute a copy of this License along with the
606
You may charge a fee for the physical act of transferring a copy,
607
and you may at your option offer warranty protection in exchange for a
610
2. You may modify your copy or copies of the Library or any portion
611
of it, thus forming a work based on the Library, and copy and
612
distribute such modifications or work under the terms of Section 1
613
above, provided that you also meet all of these conditions:
615
a) The modified work must itself be a software library.
617
b) You must cause the files modified to carry prominent notices
618
stating that you changed the files and the date of any change.
620
c) You must cause the whole of the work to be licensed at no
621
charge to all third parties under the terms of this License.
623
d) If a facility in the modified Library refers to a function or a
624
table of data to be supplied by an application program that uses
625
the facility, other than as an argument passed when the facility
626
is invoked, then you must make a good faith effort to ensure that,
627
in the event an application does not supply such function or
628
table, the facility still operates, and performs whatever part of
629
its purpose remains meaningful.
631
(For example, a function in a library to compute square roots has
632
a purpose that is entirely well-defined independent of the
633
application. Therefore, Subsection 2d requires that any
634
application-supplied function or table used by this function must
635
be optional: if the application does not supply it, the square
636
root function must still compute square roots.)
638
These requirements apply to the modified work as a whole. If
639
identifiable sections of that work are not derived from the Library,
640
and can be reasonably considered independent and separate works in
641
themselves, then this License, and its terms, do not apply to those
642
sections when you distribute them as separate works. But when you
643
distribute the same sections as part of a whole which is a work based
644
on the Library, the distribution of the whole must be on the terms of
645
this License, whose permissions for other licensees extend to the
646
entire whole, and thus to each and every part regardless of who wrote
649
Thus, it is not the intent of this section to claim rights or contest
650
your rights to work written entirely by you; rather, the intent is to
651
exercise the right to control the distribution of derivative or
652
collective works based on the Library.
654
In addition, mere aggregation of another work not based on the Library
655
with the Library (or with a work based on the Library) on a volume of
656
a storage or distribution medium does not bring the other work under
657
the scope of this License.
659
3. You may opt to apply the terms of the ordinary GNU General Public
660
License instead of this License to a given copy of the Library. To do
661
this, you must alter all the notices that refer to this License, so
662
that they refer to the ordinary GNU General Public License, version 2,
663
instead of to this License. (If a newer version than version 2 of the
664
ordinary GNU General Public License has appeared, then you can specify
665
that version instead if you wish.) Do not make any other change in
668
Once this change is made in a given copy, it is irreversible for
669
that copy, so the ordinary GNU General Public License applies to all
670
subsequent copies and derivative works made from that copy.
672
This option is useful when you wish to copy part of the code of
673
the Library into a program that is not a library.
675
4. You may copy and distribute the Library (or a portion or
676
derivative of it, under Section 2) in object code or executable form
677
under the terms of Sections 1 and 2 above provided that you accompany
678
it with the complete corresponding machine-readable source code, which
679
must be distributed under the terms of Sections 1 and 2 above on a
680
medium customarily used for software interchange.
682
If distribution of object code is made by offering access to copy
683
from a designated place, then offering equivalent access to copy the
684
source code from the same place satisfies the requirement to
685
distribute the source code, even though third parties are not
686
compelled to copy the source along with the object code.
688
5. A program that contains no derivative of any portion of the
689
Library, but is designed to work with the Library by being compiled or
690
linked with it, is called a "work that uses the Library". Such a
691
work, in isolation, is not a derivative work of the Library, and
692
therefore falls outside the scope of this License.
694
However, linking a "work that uses the Library" with the Library
695
creates an executable that is a derivative of the Library (because it
696
contains portions of the Library), rather than a "work that uses the
697
library". The executable is therefore covered by this License.
698
Section 6 states terms for distribution of such executables.
700
When a "work that uses the Library" uses material from a header file
701
that is part of the Library, the object code for the work may be a
702
derivative work of the Library even though the source code is not.
703
Whether this is true is especially significant if the work can be
704
linked without the Library, or if the work is itself a library. The
705
threshold for this to be true is not precisely defined by law.
707
If such an object file uses only numerical parameters, data
708
structure layouts and accessors, and small macros and small inline
709
functions (ten lines or less in length), then the use of the object
710
file is unrestricted, regardless of whether it is legally a derivative
711
work. (Executables containing this object code plus portions of the
712
Library will still fall under Section 6.)
714
Otherwise, if the work is a derivative of the Library, you may
715
distribute the object code for the work under the terms of Section 6.
716
Any executables containing that work also fall under Section 6,
717
whether or not they are linked directly with the Library itself.
719
6. As an exception to the Sections above, you may also compile or
720
link a "work that uses the Library" with the Library to produce a
721
work containing portions of the Library, and distribute that work
722
under terms of your choice, provided that the terms permit
723
modification of the work for the customer's own use and reverse
724
engineering for debugging such modifications.
726
You must give prominent notice with each copy of the work that the
727
Library is used in it and that the Library and its use are covered by
728
this License. You must supply a copy of this License. If the work
729
during execution displays copyright notices, you must include the
730
copyright notice for the Library among them, as well as a reference
731
directing the user to the copy of this License. Also, you must do one
734
a) Accompany the work with the complete corresponding
735
machine-readable source code for the Library including whatever
736
changes were used in the work (which must be distributed under
737
Sections 1 and 2 above); and, if the work is an executable linked
738
with the Library, with the complete machine-readable "work that
739
uses the Library", as object code and/or source code, so that the
740
user can modify the Library and then relink to produce a modified
741
executable containing the modified Library. (It is understood
742
that the user who changes the contents of definitions files in the
743
Library will not necessarily be able to recompile the application
744
to use the modified definitions.)
746
b) Accompany the work with a written offer, valid for at
747
least three years, to give the same user the materials
748
specified in Subsection 6a, above, for a charge no more
749
than the cost of performing this distribution.
751
c) If distribution of the work is made by offering access to copy
752
from a designated place, offer equivalent access to copy the above
753
specified materials from the same place.
755
d) Verify that the user has already received a copy of these
756
materials or that you have already sent this user a copy.
758
For an executable, the required form of the "work that uses the
759
Library" must include any data and utility programs needed for
760
reproducing the executable from it. However, as a special exception,
761
the source code distributed need not include anything that is normally
762
distributed (in either source or binary form) with the major
763
components (compiler, kernel, and so on) of the operating system on
764
which the executable runs, unless that component itself accompanies
767
It may happen that this requirement contradicts the license
768
restrictions of other proprietary libraries that do not normally
769
accompany the operating system. Such a contradiction means you cannot
770
use both them and the Library together in an executable that you
773
7. You may place library facilities that are a work based on the
774
Library side-by-side in a single library together with other library
775
facilities not covered by this License, and distribute such a combined
776
library, provided that the separate distribution of the work based on
777
the Library and of the other library facilities is otherwise
778
permitted, and provided that you do these two things:
780
a) Accompany the combined library with a copy of the same work
781
based on the Library, uncombined with any other library
782
facilities. This must be distributed under the terms of the
785
b) Give prominent notice with the combined library of the fact
786
that part of it is a work based on the Library, and explaining
787
where to find the accompanying uncombined form of the same work.
789
8. You may not copy, modify, sublicense, link with, or distribute
790
the Library except as expressly provided under this License. Any
791
attempt otherwise to copy, modify, sublicense, link with, or
792
distribute the Library is void, and will automatically terminate your
793
rights under this License. However, parties who have received copies,
794
or rights, from you under this License will not have their licenses
795
terminated so long as such parties remain in full compliance.
797
9. You are not required to accept this License, since you have not
798
signed it. However, nothing else grants you permission to modify or
799
distribute the Library or its derivative works. These actions are
800
prohibited by law if you do not accept this License. Therefore, by
801
modifying or distributing the Library (or any work based on the
802
Library), you indicate your acceptance of this License to do so, and
803
all its terms and conditions for copying, distributing or modifying
804
the Library or works based on it.
806
10. Each time you redistribute the Library (or any work based on the
807
Library), the recipient automatically receives a license from the
808
original licensor to copy, distribute, link with or modify the Library
809
subject to these terms and conditions. You may not impose any further
810
restrictions on the recipients' exercise of the rights granted herein.
811
You are not responsible for enforcing compliance by third parties to
814
11. If, as a consequence of a court judgment or allegation of patent
815
infringement or for any other reason (not limited to patent issues),
816
conditions are imposed on you (whether by court order, agreement or
817
otherwise) that contradict the conditions of this License, they do not
818
excuse you from the conditions of this License. If you cannot
819
distribute so as to satisfy simultaneously your obligations under this
820
License and any other pertinent obligations, then as a consequence you
821
may not distribute the Library at all. For example, if a patent
822
license would not permit royalty-free redistribution of the Library by
823
all those who receive copies directly or indirectly through you, then
824
the only way you could satisfy both it and this License would be to
825
refrain entirely from distribution of the Library.
827
If any portion of this section is held invalid or unenforceable under any
828
particular circumstance, the balance of the section is intended to apply,
829
and the section as a whole is intended to apply in other circumstances.
831
It is not the purpose of this section to induce you to infringe any
832
patents or other property right claims or to contest validity of any
833
such claims; this section has the sole purpose of protecting the
834
integrity of the free software distribution system which is
835
implemented by public license practices. Many people have made
836
generous contributions to the wide range of software distributed
837
through that system in reliance on consistent application of that
838
system; it is up to the author/donor to decide if he or she is willing
839
to distribute software through any other system and a licensee cannot
842
This section is intended to make thoroughly clear what is believed to
843
be a consequence of the rest of this License.
845
12. If the distribution and/or use of the Library is restricted in
846
certain countries either by patents or by copyrighted interfaces, the
847
original copyright holder who places the Library under this License may add
848
an explicit geographical distribution limitation excluding those countries,
849
so that distribution is permitted only in or among countries not thus
850
excluded. In such case, this License incorporates the limitation as if
851
written in the body of this License.
853
13. The Free Software Foundation may publish revised and/or new
854
versions of the Library General Public License from time to time.
855
Such new versions will be similar in spirit to the present version,
856
but may differ in detail to address new problems or concerns.
858
Each version is given a distinguishing version number. If the Library
859
specifies a version number of this License which applies to it and
860
"any later version", you have the option of following the terms and
861
conditions either of that version or of any later version published by
862
the Free Software Foundation. If the Library does not specify a
863
license version number, you may choose any version ever published by
864
the Free Software Foundation.
866
14. If you wish to incorporate parts of the Library into other free
867
programs whose distribution conditions are incompatible with these,
868
write to the author to ask for permission. For software which is
869
copyrighted by the Free Software Foundation, write to the Free
870
Software Foundation; we sometimes make exceptions for this. Our
871
decision will be guided by the two goals of preserving the free status
872
of all derivatives of our free software and of promoting the sharing
873
and reuse of software generally.
877
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
878
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
879
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
880
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
881
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
882
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
883
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
884
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
885
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
887
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
888
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
889
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
890
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
891
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
892
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
893
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
894
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
895
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
898
END OF TERMS AND CONDITIONS
900
Appendix: How to Apply These Terms to Your New Libraries
902
If you develop a new library, and you want it to be of the greatest
903
possible use to the public, we recommend making it free software that
904
everyone can redistribute and change. You can do so by permitting
905
redistribution under these terms (or, alternatively, under the terms of the
906
ordinary General Public License).
908
To apply these terms, attach the following notices to the library. It is
909
safest to attach them to the start of each source file to most effectively
910
convey the exclusion of warranty; and each file should have at least the
911
"copyright" line and a pointer to where the full notice is found.
913
<one line to give the library's name and a brief idea of what it does.>
914
Copyright (C) <year> <name of author>
916
This library is free software; you can redistribute it and/or
917
modify it under the terms of the GNU Library General Public
918
License as published by the Free Software Foundation; either
919
version 2 of the License, or (at your option) any later version.
921
This library is distributed in the hope that it will be useful,
922
but WITHOUT ANY WARRANTY; without even the implied warranty of
923
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
924
Library General Public License for more details.
926
You should have received a copy of the GNU Library General Public
927
License along with this library; if not, write to the Free
928
Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
930
Also add information on how to contact you by electronic and paper mail.
932
You should also get your employer (if you work as a programmer) or your
933
school, if any, to sign a "copyright disclaimer" for the library, if
934
necessary. Here is a sample; alter the names:
936
