1a7e760e 12INTRODUCTION
45dec87e 13
5d66e133 14The Common UNIX Printing SystemTM, ("CUPSTM"), is provided under the GNU
1a7e760e 15General Public License ("GPL") and GNU Library General Public License
16("LGPL"), Version 2. A copy of these licenses follow this introduction.
45dec87e 17
1a7e760e 18The GNU LGPL applies to the CUPS API library, located in the "cups"
19subdirectory of the CUPS source distribution and in the "/usr/include/cups"
5d66e133 20directory and "libcups.a", "libcups.sl", or "libcups.so" files in the binary
21distributions.
45dec87e 22
1a7e760e 23The GNU GPL applies to the remainder of the CUPS distribution, including the
5d66e133 24"pstoraster" filter which is based upon GNU Ghostscript 5.50 and the
7159de3d 25"pdftops" filter which is based upon Xpdf 0.92.
1a7e760e 26
27For those not familiar with the GNU GPL, the license basically allows you
28to:
29
5d66e133 30 - Use the CUPS software at no charge.
31 - Distribute verbatim copies of the software in source or binary form.
32 - Sell verbatim copies of the software for a media fee, or sell support
45dec87e 33 for the software.
5d66e133 34 - Distribute or sell printer drivers and filters that use CUPS so long as
35 source code is made available under the GPL.
45dec87e 36
37What this license does not allow you to do is make changes or add features
1a7e760e 38to CUPS and then sell a binary distribution without source code. You must
86395b64 39provide source for any new drivers, changes, or additions to the software,
5d66e133 40and all code must be provided under the GPL or LGPL as appropriate.
45dec87e 41
1a7e760e 42The GNU LGPL relaxes the "link-to" restriction, allowing you to develop
43applications that use the CUPS API library under other licenses and/or
44conditions as appropriate for your application.

94 GNU GENERAL PUBLIC LICENSE
95 Version 2, June 1991
45dec87e 96
0beadd9e 97 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
98 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
99 Everyone is permitted to copy and distribute verbatim copies
100 of this license document, but changing it is not allowed.
45dec87e 101
0beadd9e 102 Preamble
45dec87e 103
0beadd9e 104 The licenses for most software are designed to take away your
1a7e760e 105freedom to share and change it. By contrast, the GNU General Public
106License is intended to guarantee your freedom to share and change free
107software--to make sure the software is free for all its users. This
108General Public License applies to most of the Free Software
109Foundation's software and to any other program whose authors commit to
110using it. (Some other Free Software Foundation software is covered by
111the GNU Library General Public License instead.) You can apply it to
112your programs, too.
113
0beadd9e 114 When we speak of free software, we are referring to freedom, not
1a7e760e 115price. Our General Public Licenses are designed to make sure that you
116have the freedom to distribute copies of free software (and charge for
117this service if you wish), that you receive source code or can get it
118if you want it, that you can change the software or use pieces of it
119in new free programs; and that you know you can do these things.
120
0beadd9e 121 To protect your rights, we need to make restrictions that forbid
1a7e760e 122anyone to deny you these rights or to ask you to surrender the rights.
123These restrictions translate to certain responsibilities for you if you
124distribute copies of the software, or if you modify it.
125
0beadd9e 126 For example, if you distribute copies of such a program, whether
1a7e760e 127gratis or for a fee, you must give the recipients all the rights that
128you have. You must make sure that they, too, receive or can get the
129source code. And you must show them these terms so they know their
130rights.
131
0beadd9e 132 We protect your rights with two steps: (1) copyright the software, and
1a7e760e 133(2) offer you this license which gives you legal permission to copy,
134distribute and/or modify the software.
135
0beadd9e 136 Also, for each author's protection and ours, we want to make certain
1a7e760e 137that everyone understands that there is no warranty for this free
138software. If the software is modified by someone else and passed on, we
139want its recipients to know that what they have is not the original, so
140that any problems introduced by others will not reflect on the original
141authors' reputations.
142
0beadd9e 143 Finally, any free program is threatened constantly by software
1a7e760e 144patents. We wish to avoid the danger that redistributors of a free
145program will individually obtain patent licenses, in effect making the
146program proprietary. To prevent this, we have made it clear that any
147patent must be licensed for everyone's free use or not licensed at all.
148
0beadd9e 149 The precise terms and conditions for copying, distribution and
1a7e760e 150modification follow.
0beadd9e 151\f
152 GNU GENERAL PUBLIC LICENSE
153 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
154
155 0. This License applies to any program or other work which contains
156a notice placed by the copyright holder saying it may be distributed
157under the terms of this General Public License. The "Program", below,
158refers to any such program or work, and a "work based on the Program"
159means either the Program or any derivative work under copyright law:
160that is to say, a work containing the Program or a portion of it,
161either verbatim or with modifications and/or translated into another
162language. (Hereinafter, translation is included without limitation in
163the term "modification".) Each licensee is addressed as "you".
164
165Activities other than copying, distribution and modification are not
166covered by this License; they are outside its scope. The act of
167running the Program is not restricted, and the output from the Program
168is covered only if its contents constitute a work based on the
169Program (independent of having been made by running the Program).
170Whether that is true depends on what the Program does.
171
172 1. You may copy and distribute verbatim copies of the Program's
1a7e760e 173source code as you receive it, in any medium, provided that you
174conspicuously and appropriately publish on each copy an appropriate
0beadd9e 175copyright notice and disclaimer of warranty; keep intact all the
176notices that refer to this License and to the absence of any warranty;
177and give any other recipients of the Program a copy of this License
178along with the Program.
179
180You may charge a fee for the physical act of transferring a copy, and
181you may at your option offer warranty protection in exchange for a fee.
182
183 2. You may modify your copy or copies of the Program or any portion
184of it, thus forming a work based on the Program, and copy and
185distribute such modifications or work under the terms of Section 1
186above, provided that you also meet all of these conditions:
187
188 a) You must cause the modified files to carry prominent notices
189 stating that you changed the files and the date of any change.
190
191 b) You must cause any work that you distribute or publish, that in
192 whole or in part contains or is derived from the Program or any
193 part thereof, to be licensed as a whole at no charge to all third
194 parties under the terms of this License.
195
196 c) If the modified program normally reads commands interactively
197 when run, you must cause it, when started running for such
198 interactive use in the most ordinary way, to print or display an
199 announcement including an appropriate copyright notice and a
200 notice that there is no warranty (or else, saying that you provide
201 a warranty) and that users may redistribute the program under
202 these conditions, and telling the user how to view a copy of this
203 License. (Exception: if the Program itself is interactive but
204 does not normally print such an announcement, your work based on
205 the Program is not required to print an announcement.)
206\f
207These requirements apply to the modified work as a whole. If
208identifiable sections of that work are not derived from the Program,
209and can be reasonably considered independent and separate works in
210themselves, then this License, and its terms, do not apply to those
211sections when you distribute them as separate works. But when you
212distribute the same sections as part of a whole which is a work based
213on the Program, the distribution of the whole must be on the terms of
214this License, whose permissions for other licensees extend to the
215entire whole, and thus to each and every part regardless of who wrote it.
216
217Thus, it is not the intent of this section to claim rights or contest
218your rights to work written entirely by you; rather, the intent is to
219exercise the right to control the distribution of derivative or
220collective works based on the Program.
221
222In addition, mere aggregation of another work not based on the Program
223with the Program (or with a work based on the Program) on a volume of
224a storage or distribution medium does not bring the other work under
225the scope of this License.
226
227 3. You may copy and distribute the Program (or a work based on it,
228under Section 2) in object code or executable form under the terms of
229Sections 1 and 2 above provided that you also do one of the following:
230
231 a) Accompany it with the complete corresponding machine-readable
232 source code, which must be distributed under the terms of Sections
233 1 and 2 above on a medium customarily used for software interchange; or,
234
235 b) Accompany it with a written offer, valid for at least three
236 years, to give any third party, for a charge no more than your
237 cost of physically performing source distribution, a complete
238 machine-readable copy of the corresponding source code, to be
239 distributed under the terms of Sections 1 and 2 above on a medium
240 customarily used for software interchange; or,
241
242 c) Accompany it with the information you received as to the offer
243 to distribute corresponding source code. (This alternative is
244 allowed only for noncommercial distribution and only if you
245 received the program in object code or executable form with such
246 an offer, in accord with Subsection b above.)
247
248The source code for a work means the preferred form of the work for
249making modifications to it. For an executable work, complete source
250code means all the source code for all modules it contains, plus any
251associated interface definition files, plus the scripts used to
252control compilation and installation of the executable. However, as a
253special exception, the source code distributed need not include
254anything that is normally distributed (in either source or binary
255form) with the major components (compiler, kernel, and so on) of the
256operating system on which the executable runs, unless that component
257itself accompanies the executable.
258
259If distribution of executable or object code is made by offering
260access to copy from a designated place, then offering equivalent
261access to copy the source code from the same place counts as
262distribution of the source code, even though third parties are not
263compelled to copy the source along with the object code.
264\f
265 4. You may not copy, modify, sublicense, or distribute the Program
266except as expressly provided under this License. Any attempt
267otherwise to copy, modify, sublicense or distribute the Program is
268void, and will automatically terminate your rights under this License.
269However, parties who have received copies, or rights, from you under
270this License will not have their licenses terminated so long as such
271parties remain in full compliance.
272
273 5. You are not required to accept this License, since you have not
274signed it. However, nothing else grants you permission to modify or
275distribute the Program or its derivative works. These actions are
276prohibited by law if you do not accept this License. Therefore, by
277modifying or distributing the Program (or any work based on the
278Program), you indicate your acceptance of this License to do so, and
279all its terms and conditions for copying, distributing or modifying
280the Program or works based on it.
281
282 6. Each time you redistribute the Program (or any work based on the
283Program), the recipient automatically receives a license from the
284original licensor to copy, distribute or modify the Program subject to
285these terms and conditions. You may not impose any further
286restrictions on the recipients' exercise of the rights granted herein.
287You are not responsible for enforcing compliance by third parties to
1a7e760e 288this License.
289
0beadd9e 290 7. If, as a consequence of a court judgment or allegation of patent
1a7e760e 291infringement or for any other reason (not limited to patent issues),
292conditions are imposed on you (whether by court order, agreement or
293otherwise) that contradict the conditions of this License, they do not
0beadd9e 294excuse you from the conditions of this License. If you cannot
295distribute so as to satisfy simultaneously your obligations under this
296License and any other pertinent obligations, then as a consequence you
297may not distribute the Program at all. For example, if a patent
298license would not permit royalty-free redistribution of the Program by
299all those who receive copies directly or indirectly through you, then
300the only way you could satisfy both it and this License would be to
301refrain entirely from distribution of the Program.
302
303If any portion of this section is held invalid or unenforceable under
304any particular circumstance, the balance of the section is intended to
305apply and the section as a whole is intended to apply in other
306circumstances.
307
308It is not the purpose of this section to induce you to infringe any
309patents or other property right claims or to contest validity of any
310such claims; this section has the sole purpose of protecting the
311integrity of the free software distribution system, which is
312implemented by public license practices. Many people have made
313generous contributions to the wide range of software distributed
314through that system in reliance on consistent application of that
315system; it is up to the author/donor to decide if he or she is willing
316to distribute software through any other system and a licensee cannot
317impose that choice.
318
319This section is intended to make thoroughly clear what is believed to
320be a consequence of the rest of this License.
321\f
322 8. If the distribution and/or use of the Program is restricted in
323certain countries either by patents or by copyrighted interfaces, the
324original copyright holder who places the Program under this License
325may add an explicit geographical distribution limitation excluding
326those countries, so that distribution is permitted only in or among
327countries not thus excluded. In such case, this License incorporates
328the limitation as if written in the body of this License.
329
330 9. The Free Software Foundation may publish revised and/or new versions
331of the General Public License from time to time. Such new versions will
1a7e760e 332be similar in spirit to the present version, but may differ in detail to
333address new problems or concerns.
334
0beadd9e 335Each version is given a distinguishing version number. If the Program
1a7e760e 336specifies a version number of this License which applies to it and "any
337later version", you have the option of following the terms and conditions
338either of that version or of any later version published by the Free
0beadd9e 339Software Foundation. If the Program does not specify a version number of
340this License, you may choose any version ever published by the Free Software
1a7e760e 341Foundation.
342
0beadd9e 343 10. If you wish to incorporate parts of the Program into other free
344programs whose distribution conditions are different, write to the author
345to ask for permission. For software which is copyrighted by the Free
1a7e760e 346Software Foundation, write to the Free Software Foundation; we sometimes
0beadd9e 347make exceptions for this. Our decision will be guided by the two goals
348of preserving the free status of all derivatives of our free software and
349of promoting the sharing and reuse of software generally.
1a7e760e 350
0beadd9e 351 NO WARRANTY
1a7e760e 352
0beadd9e 353 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
354FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
1a7e760e 355OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
0beadd9e 356PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
1a7e760e 357OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
0beadd9e 358MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
359TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
360PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
361REPAIR OR CORRECTION.
1a7e760e 362
0beadd9e 363 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1a7e760e 364WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
0beadd9e 365REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
1a7e760e 366INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
0beadd9e 367OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
368TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
369YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
370PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
1a7e760e 371POSSIBILITY OF SUCH DAMAGES.

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