12 INTRODUCTION
13
14 The Common UNIX Printing SystemTM, ("CUPSTM"), is provided under the GNU
15 General Public License ("GPL") and GNU Library General Public License
16 ("LGPL"), Version 2. A copy of these licenses follow this introduction.
17
18 The GNU LGPL applies to the CUPS API library, located in the "cups"
19 subdirectory of the CUPS source distribution and in the "/usr/include/cups"
20 directory and "libcups.a", "libcups.sl", or "libcups.so" files in the binary
21 distributions.
22
23 The GNU GPL applies to the remainder of the CUPS distribution, including the
24 "pstoraster" filter which is based upon GNU Ghostscript 5.50 and the
25 "pdftops" filter which is based upon Xpdf 0.92.
26
27 For those not familiar with the GNU GPL, the license basically allows you
28 to:
29
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
33 for the software.
34 - Distribute or sell printer drivers and filters that use CUPS so long as
35 source code is made available under the GPL.
36
37 What this license does not allow you to do is make changes or add features
38 to CUPS and then sell a binary distribution without source code. You must
39 provide source for any new drivers, changes, or additions to the software,
40 and all code must be provided under the GPL or LGPL as appropriate.
41
42 The GNU LGPL relaxes the "link-to" restriction, allowing you to develop
43 applications that use the CUPS API library under other licenses and/or
44 conditions as appropriate for your application.

94 GNU GENERAL PUBLIC LICENSE
95 Version 2, June 1991
96
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.
101
102 Preamble
103
104 The licenses for most software are designed to take away your
105 freedom to share and change it. By contrast, the GNU General Public
106 License is intended to guarantee your freedom to share and change free
107 software--to make sure the software is free for all its users. This
108 General Public License applies to most of the Free Software
109 Foundation's software and to any other program whose authors commit to
110 using it. (Some other Free Software Foundation software is covered by
111 the GNU Library General Public License instead.) You can apply it to
112 your programs, too.
113
114 When we speak of free software, we are referring to freedom, not
115 price. Our General Public Licenses are designed to make sure that you
116 have the freedom to distribute copies of free software (and charge for
117 this service if you wish), that you receive source code or can get it
118 if you want it, that you can change the software or use pieces of it
119 in new free programs; and that you know you can do these things.
120
121 To protect your rights, we need to make restrictions that forbid
122 anyone to deny you these rights or to ask you to surrender the rights.
123 These restrictions translate to certain responsibilities for you if you
124 distribute copies of the software, or if you modify it.
125
126 For example, if you distribute copies of such a program, whether
127 gratis or for a fee, you must give the recipients all the rights that
128 you have. You must make sure that they, too, receive or can get the
129 source code. And you must show them these terms so they know their
130 rights.
131
132 We protect your rights with two steps: (1) copyright the software, and
133 (2) offer you this license which gives you legal permission to copy,
134 distribute and/or modify the software.
135
136 Also, for each author's protection and ours, we want to make certain
137 that everyone understands that there is no warranty for this free
138 software. If the software is modified by someone else and passed on, we
139 want its recipients to know that what they have is not the original, so
140 that any problems introduced by others will not reflect on the original
141 authors' reputations.
142
143 Finally, any free program is threatened constantly by software
144 patents. We wish to avoid the danger that redistributors of a free
145 program will individually obtain patent licenses, in effect making the
146 program proprietary. To prevent this, we have made it clear that any
147 patent must be licensed for everyone's free use or not licensed at all.
148
149 The precise terms and conditions for copying, distribution and
150 modification follow.
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
156 a notice placed by the copyright holder saying it may be distributed
157 under the terms of this General Public License. The "Program", below,
158 refers to any such program or work, and a "work based on the Program"
159 means either the Program or any derivative work under copyright law:
160 that is to say, a work containing the Program or a portion of it,
161 either verbatim or with modifications and/or translated into another
162 language. (Hereinafter, translation is included without limitation in
163 the term "modification".) Each licensee is addressed as "you".
164
165 Activities other than copying, distribution and modification are not
166 covered by this License; they are outside its scope. The act of
167 running the Program is not restricted, and the output from the Program
168 is covered only if its contents constitute a work based on the
169 Program (independent of having been made by running the Program).
170 Whether that is true depends on what the Program does.
171
172 1. You may copy and distribute verbatim copies of the Program's
173 source code as you receive it, in any medium, provided that you
174 conspicuously and appropriately publish on each copy an appropriate
175 copyright notice and disclaimer of warranty; keep intact all the
176 notices that refer to this License and to the absence of any warranty;
177 and give any other recipients of the Program a copy of this License
178 along with the Program.
179
180 You may charge a fee for the physical act of transferring a copy, and
181 you 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
184 of it, thus forming a work based on the Program, and copy and
185 distribute such modifications or work under the terms of Section 1
186 above, 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
207 These requirements apply to the modified work as a whole. If
208 identifiable sections of that work are not derived from the Program,
209 and can be reasonably considered independent and separate works in
210 themselves, then this License, and its terms, do not apply to those
211 sections when you distribute them as separate works. But when you
212 distribute the same sections as part of a whole which is a work based
213 on the Program, the distribution of the whole must be on the terms of
214 this License, whose permissions for other licensees extend to the
215 entire whole, and thus to each and every part regardless of who wrote it.
216
217 Thus, it is not the intent of this section to claim rights or contest
218 your rights to work written entirely by you; rather, the intent is to
219 exercise the right to control the distribution of derivative or
220 collective works based on the Program.
221
222 In addition, mere aggregation of another work not based on the Program
223 with the Program (or with a work based on the Program) on a volume of
224 a storage or distribution medium does not bring the other work under
225 the scope of this License.
226
227 3. You may copy and distribute the Program (or a work based on it,
228 under Section 2) in object code or executable form under the terms of
229 Sections 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
248 The source code for a work means the preferred form of the work for
249 making modifications to it. For an executable work, complete source
250 code means all the source code for all modules it contains, plus any
251 associated interface definition files, plus the scripts used to
252 control compilation and installation of the executable. However, as a
253 special exception, the source code distributed need not include
254 anything that is normally distributed (in either source or binary
255 form) with the major components (compiler, kernel, and so on) of the
256 operating system on which the executable runs, unless that component
257 itself accompanies the executable.
258
259 If distribution of executable or object code is made by offering
260 access to copy from a designated place, then offering equivalent
261 access to copy the source code from the same place counts as
262 distribution of the source code, even though third parties are not
263 compelled to copy the source along with the object code.
264 \f
265 4. You may not copy, modify, sublicense, or distribute the Program
266 except as expressly provided under this License. Any attempt
267 otherwise to copy, modify, sublicense or distribute the Program is
268 void, and will automatically terminate your rights under this License.
269 However, parties who have received copies, or rights, from you under
270 this License will not have their licenses terminated so long as such
271 parties remain in full compliance.
272
273 5. You are not required to accept this License, since you have not
274 signed it. However, nothing else grants you permission to modify or
275 distribute the Program or its derivative works. These actions are
276 prohibited by law if you do not accept this License. Therefore, by
277 modifying or distributing the Program (or any work based on the
278 Program), you indicate your acceptance of this License to do so, and
279 all its terms and conditions for copying, distributing or modifying
280 the Program or works based on it.
281
282 6. Each time you redistribute the Program (or any work based on the
283 Program), the recipient automatically receives a license from the
284 original licensor to copy, distribute or modify the Program subject to
285 these terms and conditions. You may not impose any further
286 restrictions on the recipients' exercise of the rights granted herein.
287 You are not responsible for enforcing compliance by third parties to
288 this License.
289
290 7. If, as a consequence of a court judgment or allegation of patent
291 infringement or for any other reason (not limited to patent issues),
292 conditions are imposed on you (whether by court order, agreement or
293 otherwise) that contradict the conditions of this License, they do not
294 excuse you from the conditions of this License. If you cannot
295 distribute so as to satisfy simultaneously your obligations under this
296 License and any other pertinent obligations, then as a consequence you
297 may not distribute the Program at all. For example, if a patent
298 license would not permit royalty-free redistribution of the Program by
299 all those who receive copies directly or indirectly through you, then
300 the only way you could satisfy both it and this License would be to
301 refrain entirely from distribution of the Program.
302
303 If any portion of this section is held invalid or unenforceable under
304 any particular circumstance, the balance of the section is intended to
305 apply and the section as a whole is intended to apply in other
306 circumstances.
307
308 It is not the purpose of this section to induce you to infringe any
309 patents or other property right claims or to contest validity of any
310 such claims; this section has the sole purpose of protecting the
311 integrity of the free software distribution system, which is
312 implemented by public license practices. Many people have made
313 generous contributions to the wide range of software distributed
314 through that system in reliance on consistent application of that
315 system; it is up to the author/donor to decide if he or she is willing
316 to distribute software through any other system and a licensee cannot
317 impose that choice.
318
319 This section is intended to make thoroughly clear what is believed to
320 be a consequence of the rest of this License.
321 \f
322 8. If the distribution and/or use of the Program is restricted in
323 certain countries either by patents or by copyrighted interfaces, the
324 original copyright holder who places the Program under this License
325 may add an explicit geographical distribution limitation excluding
326 those countries, so that distribution is permitted only in or among
327 countries not thus excluded. In such case, this License incorporates
328 the limitation as if written in the body of this License.
329
330 9. The Free Software Foundation may publish revised and/or new versions
331 of the General Public License from time to time. Such new versions will
332 be similar in spirit to the present version, but may differ in detail to
333 address new problems or concerns.
334
335 Each version is given a distinguishing version number. If the Program
336 specifies a version number of this License which applies to it and "any
337 later version", you have the option of following the terms and conditions
338 either of that version or of any later version published by the Free
339 Software Foundation. If the Program does not specify a version number of
340 this License, you may choose any version ever published by the Free Software
341 Foundation.
342
343 10. If you wish to incorporate parts of the Program into other free
344 programs whose distribution conditions are different, write to the author
345 to ask for permission. For software which is copyrighted by the Free
346 Software Foundation, write to the Free Software Foundation; we sometimes
347 make exceptions for this. Our decision will be guided by the two goals
348 of preserving the free status of all derivatives of our free software and
349 of promoting the sharing and reuse of software generally.
350
351 NO WARRANTY
352
353 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
354 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
355 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
356 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
357 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
358 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
359 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
360 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
361 REPAIR OR CORRECTION.
362
363 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
364 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
365 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
366 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
367 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
368 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
369 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
370 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
371 POSSIBILITY 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
390 freedom to share and change it. By contrast, the GNU General Public
391 Licenses are intended to guarantee your freedom to share and change
392 free software--to make sure the software is free for all its users.
393
394 This license, the Library General Public License, applies to some
395 specially designated Free Software Foundation software, and to any
396 other libraries whose authors decide to use it. You can use it for
397 your libraries, too.
398
399 When we speak of free software, we are referring to freedom, not
400 price. Our General Public Licenses are designed to make sure that you
401 have the freedom to distribute copies of free software (and charge for
402 this service if you wish), that you receive source code or can get it
403 if you want it, that you can change the software or use pieces of it
404 in 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
407 anyone to deny you these rights or to ask you to surrender the rights.
408 These restrictions translate to certain responsibilities for you if
409 you distribute copies of the library, or if you modify it.
410
411 For example, if you distribute copies of the library, whether gratis
412 or for a fee, you must give the recipients all the rights that we gave
413 you. You must make sure that they, too, receive or can get the source
414 code. If you link a program with the library, you must provide
415 complete object files to the recipients so that they can relink them
416 with the library, after making changes to the library and recompiling
417 it. 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
420 the library, and (2) offer you this license which gives you legal
421 permission to copy, distribute and/or modify the library.
422
423 Also, for each distributor's protection, we want to make certain
424 that everyone understands that there is no warranty for this free
425 library. If the library is modified by someone else and passed on, we
426 want its recipients to know that what they have is not the original
427 version, so that any problems introduced by others will not reflect on
428 the original authors' reputations.
429 \f
430 Finally, any free program is threatened constantly by software
431 patents. We wish to avoid the danger that companies distributing free
432 software will individually obtain patent licenses, thus in effect
433 transforming the program into proprietary software. To prevent this,
434 we have made it clear that any patent must be licensed for everyone's
435 free use or not licensed at all.
436
437 Most GNU software, including some libraries, is covered by the ordinary
438 GNU General Public License, which was designed for utility programs. This
439 license, the GNU Library General Public License, applies to certain
440 designated libraries. This license is quite different from the ordinary
441 one; be sure to read it in full, and don't assume that anything in it is
442 the same as in the ordinary license.
443
444 The reason we have a separate public license for some libraries is that
445 they blur the distinction we usually make between modifying or adding to a
446 program and simply using it. Linking a program with a library, without
447 changing the library, is in some sense simply using the library, and is
448 analogous to running a utility program or application program. However, in
449 a textual and legal sense, the linked executable is a combined work, a
450 derivative of the original library, and the ordinary General Public License
451 treats it as such.
452
453 Because of this blurred distinction, using the ordinary General
454 Public License for libraries did not effectively promote software
455 sharing, because most developers did not use the libraries. We
456 concluded that weaker conditions might promote sharing better.
457
458 However, unrestricted linking of non-free programs would deprive the
459 users of those programs of all benefit from the free status of the
460 libraries themselves. This Library General Public License is intended to
461 permit developers of non-free programs to use free libraries, while
462 preserving your freedom as a user of such programs to change the free
463 libraries that are incorporated in them. (We have not seen how to achieve
464 this as regards changes in header files, but we have achieved it as regards
465 changes in the actual functions of the Library.) The hope is that this
466 will lead to faster development of free libraries.
467
468 The precise terms and conditions for copying, distribution and
469 modification follow. Pay close attention to the difference between a
470 "work based on the library" and a "work that uses the library". The
471 former contains code derived from the library, while the latter only
472 works together with the library.
473
474 Note that it is possible for a library to be covered by the ordinary
475 General 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
481 contains a notice placed by the copyright holder or other authorized
482 party saying it may be distributed under the terms of this Library
483 General Public License (also called "this License"). Each licensee is
484 addressed as "you".
485
486 A "library" means a collection of software functions and/or data
487 prepared 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
491 which has been distributed under these terms. A "work based on the
492 Library" means either the Library or any derivative work under
493 copyright law: that is to say, a work containing the Library or a
494 portion of it, either verbatim or with modifications and/or translated
495 straightforwardly into another language. (Hereinafter, translation is
496 included without limitation in the term "modification".)
497
498 "Source code" for a work means the preferred form of the work for
499 making modifications to it. For a library, complete source code means
500 all the source code for all modules it contains, plus any associated
501 interface definition files, plus the scripts used to control compilation
502 and installation of the library.
503
504 Activities other than copying, distribution and modification are not
505 covered by this License; they are outside its scope. The act of
506 running a program using the Library is not restricted, and output from
507 such a program is covered only if its contents constitute a work based
508 on the Library (independent of the use of the Library in a tool for
509 writing it). Whether that is true depends on what the Library does
510 and what the program that uses the Library does.
511
512 1. You may copy and distribute verbatim copies of the Library's
513 complete source code as you receive it, in any medium, provided that
514 you conspicuously and appropriately publish on each copy an
515 appropriate copyright notice and disclaimer of warranty; keep intact
516 all the notices that refer to this License and to the absence of any
517 warranty; and distribute a copy of this License along with the
518 Library.
519
520 You may charge a fee for the physical act of transferring a copy,
521 and you may at your option offer warranty protection in exchange for a
522 fee.
523 \f
524 2. You may modify your copy or copies of the Library or any portion
525 of it, thus forming a work based on the Library, and copy and
526 distribute such modifications or work under the terms of Section 1
527 above, 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
552 These requirements apply to the modified work as a whole. If
553 identifiable sections of that work are not derived from the Library,
554 and can be reasonably considered independent and separate works in
555 themselves, then this License, and its terms, do not apply to those
556 sections when you distribute them as separate works. But when you
557 distribute the same sections as part of a whole which is a work based
558 on the Library, the distribution of the whole must be on the terms of
559 this License, whose permissions for other licensees extend to the
560 entire whole, and thus to each and every part regardless of who wrote
561 it.
562
563 Thus, it is not the intent of this section to claim rights or contest
564 your rights to work written entirely by you; rather, the intent is to
565 exercise the right to control the distribution of derivative or
566 collective works based on the Library.
567
568 In addition, mere aggregation of another work not based on the Library
569 with the Library (or with a work based on the Library) on a volume of
570 a storage or distribution medium does not bring the other work under
571 the scope of this License.
572
573 3. You may opt to apply the terms of the ordinary GNU General Public
574 License instead of this License to a given copy of the Library. To do
575 this, you must alter all the notices that refer to this License, so
576 that they refer to the ordinary GNU General Public License, version 2,
577 instead of to this License. (If a newer version than version 2 of the
578 ordinary GNU General Public License has appeared, then you can specify
579 that version instead if you wish.) Do not make any other change in
580 these notices.
581 \f
582 Once this change is made in a given copy, it is irreversible for
583 that copy, so the ordinary GNU General Public License applies to all
584 subsequent copies and derivative works made from that copy.
585
586 This option is useful when you wish to copy part of the code of
587 the Library into a program that is not a library.
588
589 4. You may copy and distribute the Library (or a portion or
590 derivative of it, under Section 2) in object code or executable form
591 under the terms of Sections 1 and 2 above provided that you accompany
592 it with the complete corresponding machine-readable source code, which
593 must be distributed under the terms of Sections 1 and 2 above on a
594 medium customarily used for software interchange.
595
596 If distribution of object code is made by offering access to copy
597 from a designated place, then offering equivalent access to copy the
598 source code from the same place satisfies the requirement to
599 distribute the source code, even though third parties are not
600 compelled to copy the source along with the object code.
601
602 5. A program that contains no derivative of any portion of the
603 Library, but is designed to work with the Library by being compiled or
604 linked with it, is called a "work that uses the Library". Such a
605 work, in isolation, is not a derivative work of the Library, and
606 therefore falls outside the scope of this License.
607
608 However, linking a "work that uses the Library" with the Library
609 creates an executable that is a derivative of the Library (because it
610 contains portions of the Library), rather than a "work that uses the
611 library". The executable is therefore covered by this License.
612 Section 6 states terms for distribution of such executables.
613
614 When a "work that uses the Library" uses material from a header file
615 that is part of the Library, the object code for the work may be a
616 derivative work of the Library even though the source code is not.
617 Whether this is true is especially significant if the work can be
618 linked without the Library, or if the work is itself a library. The
619 threshold for this to be true is not precisely defined by law.
620
621 If such an object file uses only numerical parameters, data
622 structure layouts and accessors, and small macros and small inline
623 functions (ten lines or less in length), then the use of the object
624 file is unrestricted, regardless of whether it is legally a derivative
625 work. (Executables containing this object code plus portions of the
626 Library will still fall under Section 6.)
627
628 Otherwise, if the work is a derivative of the Library, you may
629 distribute the object code for the work under the terms of Section 6.
630 Any executables containing that work also fall under Section 6,
631 whether 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
634 link a "work that uses the Library" with the Library to produce a
635 work containing portions of the Library, and distribute that work
636 under terms of your choice, provided that the terms permit
637 modification of the work for the customer's own use and reverse
638 engineering for debugging such modifications.
639
640 You must give prominent notice with each copy of the work that the
641 Library is used in it and that the Library and its use are covered by
642 this License. You must supply a copy of this License. If the work
643 during execution displays copyright notices, you must include the
644 copyright notice for the Library among them, as well as a reference
645 directing the user to the copy of this License. Also, you must do one
646 of 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
673 Library" must include any data and utility programs needed for
674 reproducing the executable from it. However, as a special exception,
675 the source code distributed need not include anything that is normally
676 distributed (in either source or binary form) with the major
677 components (compiler, kernel, and so on) of the operating system on
678 which the executable runs, unless that component itself accompanies
679 the executable.
680
681 It may happen that this requirement contradicts the license
682 restrictions of other proprietary libraries that do not normally
683 accompany the operating system. Such a contradiction means you cannot
684 use both them and the Library together in an executable that you
685 distribute.
686 \f
687 7. You may place library facilities that are a work based on the
688 Library side-by-side in a single library together with other library
689 facilities not covered by this License, and distribute such a combined
690 library, provided that the separate distribution of the work based on
691 the Library and of the other library facilities is otherwise
692 permitted, 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
704 the Library except as expressly provided under this License. Any
705 attempt otherwise to copy, modify, sublicense, link with, or
706 distribute the Library is void, and will automatically terminate your
707 rights under this License. However, parties who have received copies,
708 or rights, from you under this License will not have their licenses
709 terminated so long as such parties remain in full compliance.
710
711 9. You are not required to accept this License, since you have not
712 signed it. However, nothing else grants you permission to modify or
713 distribute the Library or its derivative works. These actions are
714 prohibited by law if you do not accept this License. Therefore, by
715 modifying or distributing the Library (or any work based on the
716 Library), you indicate your acceptance of this License to do so, and
717 all its terms and conditions for copying, distributing or modifying
718 the Library or works based on it.
719
720 10. Each time you redistribute the Library (or any work based on the
721 Library), the recipient automatically receives a license from the
722 original licensor to copy, distribute, link with or modify the Library
723 subject to these terms and conditions. You may not impose any further
724 restrictions on the recipients' exercise of the rights granted herein.
725 You are not responsible for enforcing compliance by third parties to
726 this License.
727 \f
728 11. If, as a consequence of a court judgment or allegation of patent
729 infringement or for any other reason (not limited to patent issues),
730 conditions are imposed on you (whether by court order, agreement or
731 otherwise) that contradict the conditions of this License, they do not
732 excuse you from the conditions of this License. If you cannot
733 distribute so as to satisfy simultaneously your obligations under this
734 License and any other pertinent obligations, then as a consequence you
735 may not distribute the Library at all. For example, if a patent
736 license would not permit royalty-free redistribution of the Library by
737 all those who receive copies directly or indirectly through you, then
738 the only way you could satisfy both it and this License would be to
739 refrain entirely from distribution of the Library.
740
741 If any portion of this section is held invalid or unenforceable under any
742 particular circumstance, the balance of the section is intended to apply,
743 and the section as a whole is intended to apply in other circumstances.
744
745 It is not the purpose of this section to induce you to infringe any
746 patents or other property right claims or to contest validity of any
747 such claims; this section has the sole purpose of protecting the
748 integrity of the free software distribution system which is
749 implemented by public license practices. Many people have made
750 generous contributions to the wide range of software distributed
751 through that system in reliance on consistent application of that
752 system; it is up to the author/donor to decide if he or she is willing
753 to distribute software through any other system and a licensee cannot
754 impose that choice.
755
756 This section is intended to make thoroughly clear what is believed to
757 be a consequence of the rest of this License.
758
759 12. If the distribution and/or use of the Library is restricted in
760 certain countries either by patents or by copyrighted interfaces, the
761 original copyright holder who places the Library under this License may add
762 an explicit geographical distribution limitation excluding those countries,
763 so that distribution is permitted only in or among countries not thus
764 excluded. In such case, this License incorporates the limitation as if
765 written in the body of this License.
766
767 13. The Free Software Foundation may publish revised and/or new
768 versions of the Library General Public License from time to time.
769 Such new versions will be similar in spirit to the present version,
770 but may differ in detail to address new problems or concerns.
771
772 Each version is given a distinguishing version number. If the Library
773 specifies a version number of this License which applies to it and
774 "any later version", you have the option of following the terms and
775 conditions either of that version or of any later version published by
776 the Free Software Foundation. If the Library does not specify a
777 license version number, you may choose any version ever published by
778 the Free Software Foundation.
779 \f
780 14. If you wish to incorporate parts of the Library into other free
781 programs whose distribution conditions are incompatible with these,
782 write to the author to ask for permission. For software which is
783 copyrighted by the Free Software Foundation, write to the Free
784 Software Foundation; we sometimes make exceptions for this. Our
785 decision will be guided by the two goals of preserving the free status
786 of all derivatives of our free software and of promoting the sharing
787 and reuse of software generally.
788
789 NO WARRANTY
790
791 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
792 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
793 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
794 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
795 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
796 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
797 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
798 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
799 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
800
801 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
802 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
803 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
804 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
805 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
806 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
807 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
808 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
809 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
810 DAMAGES.
811
812 END OF TERMS AND CONDITIONS
