10 INTRODUCTION
11
12 CUPS(tm) is provided under the GNU General Public License ("GPL")
13 and GNU Library General Public License ("LGPL"), Version 2, with
14 exceptions for Apple operating systems and the OpenSSL toolkit. A
15 copy of the exceptions and licenses follow this introduction.
16
17 The GNU LGPL applies to the CUPS and CUPS Imaging libraries
18 located in the "cups" and "filter" subdirectories of the CUPS
19 source distribution and the files in the "test" subdirectory. The
20 GNU GPL applies to the remainder of the CUPS distribution.
21
22 For those not familiar with the GNU GPL, the license basically
23 allows you to:
24
25 - Use the CUPS software at no charge.
26 - Distribute verbatim copies of the software in source or
27 binary form.
28 - Sell verbatim copies of the software for a media fee, or
29 sell support for the software.
30
31 What this license *does not* allow you to do is make changes or
32 add features to CUPS and then sell a binary distribution without
33 source code. You must provide source for any changes or additions
34 to the software, and all code must be provided under the GPL or
35 LGPL as appropriate. The only exceptions to this are the portions
36 of the CUPS software covered by the Apple operating system
37 license exceptions outlined later in this license agreement.
38
39 The GNU LGPL relaxes the "link-to" restriction, allowing you to
40 develop applications that use the CUPS and CUPS Imaging libraries
41 under other licenses and/or conditions as appropriate for your
42 application, driver, or filter.
43
44
45 LICENSE EXCEPTIONS
46
47 In addition, as the copyright holder of CUPS, Apple Inc. grants
48 the following special exceptions:
49
50 1. Apple Operating System Development License Exception;
51
52 a. Software that is developed by any person or entity
53 for an Apple Operating System ("Apple OS-Developed
54 Software"), including but not limited to Apple and
55 third party printer drivers, filters, and backends
56 for an Apple Operating System, that is linked to the
57 CUPS imaging library or based on any sample filters
58 or backends provided with CUPS shall not be
59 considered to be a derivative work or collective work
60 based on the CUPS program and is exempt from the
61 mandatory source code release clauses of the GNU GPL.
62 You may therefore distribute linked combinations of
63 the CUPS imaging library with Apple OS-Developed
64 Software without releasing the source code of the
65 Apple OS-Developed Software. You may also use sample
66 filters and backends provided with CUPS to develop
67 Apple OS-Developed Software without releasing the
68 source code of the Apple OS-Developed Software.
69
70 b. An Apple Operating System means any operating system
71 software developed and/or marketed by Apple Inc.,
72 including but not limited to all existing releases and
73 versions of Apple's Darwin, OS X, and OS X Server
74 products and all follow-on releases and future
75 versions thereof.
76
77 c. This exception is only available for Apple
78 OS-Developed Software and does not apply to software
79 that is distributed for use on other operating
80 systems.
81
82 d. All CUPS software that falls under this license
83 exception have the following text at the top of each
84 source file:
85
86 This file is subject to the Apple OS-Developed
87 Software exception.
88
89 2. OpenSSL Toolkit License Exception;
90
91 a. Apple Inc. explicitly allows the compilation and
92 distribution of the CUPS software with the OpenSSL
93 Toolkit.
94
95 No developer is required to provide these exceptions in a
96 derived work.
97
98
99 KERBEROS SUPPORT CODE
100
101 The Kerberos support code ("KSC") is copyright 2006 by Jelmer
102 Vernooij and is provided 'as-is', without any express or implied
103 warranty. In no event will the author or Apple Inc. be held
104 liable for any damages arising from the use of the KSC.
105
106 Sources files containing KSC have the following text at the top
107 of each source file:
108
109 This file contains Kerberos support code, copyright 2006 by
110 Jelmer Vernooij.
111
112 The KSC copyright and license apply only to Kerberos-related
113 feature code in CUPS. Such code is typically conditionally
114 compiled based on the present of the HAVE_GSSAPI preprocessor
115 definition.
116
117 Permission is granted to anyone to use the KSC for any purpose,
118 including commercial applications, and to alter it and
119 redistribute it freely, subject to the following restrictions:
120
121 1. The origin of the KSC must not be misrepresented; you
122 must not claim that you wrote the original software. If
123 you use the KSC in a product, an acknowledgment in the
124 product documentation would be appreciated but is not
125 required.
126
127 2. Altered source versions must be plainly marked as such,
128 and must not be misrepresented as being the original
129 software.
130
131 3. This notice may not be removed or altered from any source
132 distribution.
133
134
135 TRADEMARKS
136
137 CUPS and the CUPS logo (the "CUPS Marks") are trademarks of Apple
138 Inc. Apple grants you a non-exclusive and non-transferable right
139 to use the CUPS Marks in any direct port or binary distribution
140 incorporating CUPS software and in any promotional material
141 therefor. You agree that your products will meet the highest
142 levels of quality and integrity for similar goods, not be unlawful,
143 and be developed, manufactured, and distributed in compliance with
144 this license. You will not interfere with Apple's rights in the
145 CUPS Marks, and all use of the CUPS Marks shall inure to the
146 benefit of Apple. This license does not apply to use of the CUPS
147 Marks in a derivative products, which requires prior written
148 permission from Apple Inc.

150 GNU GENERAL PUBLIC LICENSE
151 Version 2, June 1991
152
153 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
154 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
155 Everyone is permitted to copy and distribute verbatim copies
156 of this license document, but changing it is not allowed.
157
158 Preamble
159
160 The licenses for most software are designed to take away your
161 freedom to share and change it. By contrast, the GNU General Public
162 License is intended to guarantee your freedom to share and change free
163 software--to make sure the software is free for all its users. This
164 General Public License applies to most of the Free Software
165 Foundation's software and to any other program whose authors commit to
166 using it. (Some other Free Software Foundation software is covered by
167 the GNU Library General Public License instead.) You can apply it to
168 your programs, too.
169
170 When we speak of free software, we are referring to freedom, not
171 price. Our General Public Licenses are designed to make sure that you
172 have the freedom to distribute copies of free software (and charge for
173 this service if you wish), that you receive source code or can get it
174 if you want it, that you can change the software or use pieces of it
175 in new free programs; and that you know you can do these things.
176
177 To protect your rights, we need to make restrictions that forbid
178 anyone to deny you these rights or to ask you to surrender the rights.
179 These restrictions translate to certain responsibilities for you if you
180 distribute copies of the software, or if you modify it.
181
182 For example, if you distribute copies of such a program, whether
183 gratis or for a fee, you must give the recipients all the rights that
184 you have. You must make sure that they, too, receive or can get the
185 source code. And you must show them these terms so they know their
186 rights.
187
188 We protect your rights with two steps: (1) copyright the software, and
189 (2) offer you this license which gives you legal permission to copy,
190 distribute and/or modify the software.
191
192 Also, for each author's protection and ours, we want to make certain
193 that everyone understands that there is no warranty for this free
194 software. If the software is modified by someone else and passed on, we
195 want its recipients to know that what they have is not the original, so
196 that any problems introduced by others will not reflect on the original
197 authors' reputations.
198
199 Finally, any free program is threatened constantly by software
200 patents. We wish to avoid the danger that redistributors of a free
201 program will individually obtain patent licenses, in effect making the
202 program proprietary. To prevent this, we have made it clear that any
203 patent must be licensed for everyone's free use or not licensed at all.
204
205 The precise terms and conditions for copying, distribution and
206 modification follow.
207 \f
208 GNU GENERAL PUBLIC LICENSE
209 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
210
211 0. This License applies to any program or other work which contains
212 a notice placed by the copyright holder saying it may be distributed
213 under the terms of this General Public License. The "Program", below,
214 refers to any such program or work, and a "work based on the Program"
215 means either the Program or any derivative work under copyright law:
216 that is to say, a work containing the Program or a portion of it,
217 either verbatim or with modifications and/or translated into another
218 language. (Hereinafter, translation is included without limitation in
219 the term "modification".) Each licensee is addressed as "you".
220
221 Activities other than copying, distribution and modification are not
222 covered by this License; they are outside its scope. The act of
223 running the Program is not restricted, and the output from the Program
224 is covered only if its contents constitute a work based on the
225 Program (independent of having been made by running the Program).
226 Whether that is true depends on what the Program does.
227
228 1. You may copy and distribute verbatim copies of the Program's
229 source code as you receive it, in any medium, provided that you
230 conspicuously and appropriately publish on each copy an appropriate
231 copyright notice and disclaimer of warranty; keep intact all the
232 notices that refer to this License and to the absence of any warranty;
233 and give any other recipients of the Program a copy of this License
234 along with the Program.
235
236 You may charge a fee for the physical act of transferring a copy, and
237 you may at your option offer warranty protection in exchange for a fee.
238
239 2. You may modify your copy or copies of the Program or any portion
240 of it, thus forming a work based on the Program, and copy and
241 distribute such modifications or work under the terms of Section 1
242 above, provided that you also meet all of these conditions:
243
244 a) You must cause the modified files to carry prominent notices
245 stating that you changed the files and the date of any change.
246
247 b) You must cause any work that you distribute or publish, that in
248 whole or in part contains or is derived from the Program or any
249 part thereof, to be licensed as a whole at no charge to all third
250 parties under the terms of this License.
251
252 c) If the modified program normally reads commands interactively
253 when run, you must cause it, when started running for such
254 interactive use in the most ordinary way, to print or display an
255 announcement including an appropriate copyright notice and a
256 notice that there is no warranty (or else, saying that you provide
257 a warranty) and that users may redistribute the program under
258 these conditions, and telling the user how to view a copy of this
259 License. (Exception: if the Program itself is interactive but
260 does not normally print such an announcement, your work based on
261 the Program is not required to print an announcement.)
262 \f
263 These requirements apply to the modified work as a whole. If
264 identifiable sections of that work are not derived from the Program,
265 and can be reasonably considered independent and separate works in
266 themselves, then this License, and its terms, do not apply to those
267 sections when you distribute them as separate works. But when you
268 distribute the same sections as part of a whole which is a work based
269 on the Program, the distribution of the whole must be on the terms of
270 this License, whose permissions for other licensees extend to the
271 entire whole, and thus to each and every part regardless of who wrote it.
272
273 Thus, it is not the intent of this section to claim rights or contest
274 your rights to work written entirely by you; rather, the intent is to
275 exercise the right to control the distribution of derivative or
276 collective works based on the Program.
277
278 In addition, mere aggregation of another work not based on the Program
279 with the Program (or with a work based on the Program) on a volume of
280 a storage or distribution medium does not bring the other work under
281 the scope of this License.
282
283 3. You may copy and distribute the Program (or a work based on it,
284 under Section 2) in object code or executable form under the terms of
285 Sections 1 and 2 above provided that you also do one of the following:
286
287 a) Accompany it with the complete corresponding machine-readable
288 source code, which must be distributed under the terms of Sections
289 1 and 2 above on a medium customarily used for software interchange; or,
290
291 b) Accompany it with a written offer, valid for at least three
292 years, to give any third party, for a charge no more than your
293 cost of physically performing source distribution, a complete
294 machine-readable copy of the corresponding source code, to be
295 distributed under the terms of Sections 1 and 2 above on a medium
296 customarily used for software interchange; or,
297
298 c) Accompany it with the information you received as to the offer
299 to distribute corresponding source code. (This alternative is
300 allowed only for noncommercial distribution and only if you
301 received the program in object code or executable form with such
302 an offer, in accord with Subsection b above.)
303
304 The source code for a work means the preferred form of the work for
305 making modifications to it. For an executable work, complete source
306 code means all the source code for all modules it contains, plus any
307 associated interface definition files, plus the scripts used to
308 control compilation and installation of the executable. However, as a
309 special exception, the source code distributed need not include
310 anything that is normally distributed (in either source or binary
311 form) with the major components (compiler, kernel, and so on) of the
312 operating system on which the executable runs, unless that component
313 itself accompanies the executable.
314
315 If distribution of executable or object code is made by offering
316 access to copy from a designated place, then offering equivalent
317 access to copy the source code from the same place counts as
318 distribution of the source code, even though third parties are not
319 compelled to copy the source along with the object code.
320 \f
321 4. You may not copy, modify, sublicense, or distribute the Program
322 except as expressly provided under this License. Any attempt
323 otherwise to copy, modify, sublicense or distribute the Program is
324 void, and will automatically terminate your rights under this License.
325 However, parties who have received copies, or rights, from you under
326 this License will not have their licenses terminated so long as such
327 parties remain in full compliance.
328
329 5. You are not required to accept this License, since you have not
330 signed it. However, nothing else grants you permission to modify or
331 distribute the Program or its derivative works. These actions are
332 prohibited by law if you do not accept this License. Therefore, by
333 modifying or distributing the Program (or any work based on the
334 Program), you indicate your acceptance of this License to do so, and
335 all its terms and conditions for copying, distributing or modifying
336 the Program or works based on it.
337
338 6. Each time you redistribute the Program (or any work based on the
339 Program), the recipient automatically receives a license from the
340 original licensor to copy, distribute or modify the Program subject to
341 these terms and conditions. You may not impose any further
342 restrictions on the recipients' exercise of the rights granted herein.
343 You are not responsible for enforcing compliance by third parties to
344 this License.
345
346 7. If, as a consequence of a court judgment or allegation of patent
347 infringement or for any other reason (not limited to patent issues),
348 conditions are imposed on you (whether by court order, agreement or
349 otherwise) that contradict the conditions of this License, they do not
350 excuse you from the conditions of this License. If you cannot
351 distribute so as to satisfy simultaneously your obligations under this
352 License and any other pertinent obligations, then as a consequence you
353 may not distribute the Program at all. For example, if a patent
354 license would not permit royalty-free redistribution of the Program by
355 all those who receive copies directly or indirectly through you, then
356 the only way you could satisfy both it and this License would be to
357 refrain entirely from distribution of the Program.
358
359 If any portion of this section is held invalid or unenforceable under
360 any particular circumstance, the balance of the section is intended to
361 apply and the section as a whole is intended to apply in other
362 circumstances.
363
364 It is not the purpose of this section to induce you to infringe any
365 patents or other property right claims or to contest validity of any
366 such claims; this section has the sole purpose of protecting the
367 integrity of the free software distribution system, which is
368 implemented by public license practices. Many people have made
369 generous contributions to the wide range of software distributed
370 through that system in reliance on consistent application of that
371 system; it is up to the author/donor to decide if he or she is willing
372 to distribute software through any other system and a licensee cannot
373 impose that choice.
374
375 This section is intended to make thoroughly clear what is believed to
376 be a consequence of the rest of this License.
377 \f
378 8. If the distribution and/or use of the Program is restricted in
379 certain countries either by patents or by copyrighted interfaces, the
380 original copyright holder who places the Program under this License
381 may add an explicit geographical distribution limitation excluding
382 those countries, so that distribution is permitted only in or among
383 countries not thus excluded. In such case, this License incorporates
384 the limitation as if written in the body of this License.
385
386 9. The Free Software Foundation may publish revised and/or new versions
387 of the General Public License from time to time. Such new versions will
388 be similar in spirit to the present version, but may differ in detail to
389 address new problems or concerns.
390
391 Each version is given a distinguishing version number. If the Program
392 specifies a version number of this License which applies to it and "any
393 later version", you have the option of following the terms and conditions
394 either of that version or of any later version published by the Free
395 Software Foundation. If the Program does not specify a version number of
396 this License, you may choose any version ever published by the Free Software
397 Foundation.
398
399 10. If you wish to incorporate parts of the Program into other free
400 programs whose distribution conditions are different, write to the author
401 to ask for permission. For software which is copyrighted by the Free
402 Software Foundation, write to the Free Software Foundation; we sometimes
403 make exceptions for this. Our decision will be guided by the two goals
404 of preserving the free status of all derivatives of our free software and
405 of promoting the sharing and reuse of software generally.
406
407 NO WARRANTY
408
409 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
410 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
411 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
412 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
413 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
414 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
415 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
416 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
417 REPAIR OR CORRECTION.
418
419 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
420 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
421 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
422 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
423 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
424 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
425 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
426 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
427 POSSIBILITY OF SUCH DAMAGES.
428
429 END OF TERMS AND CONDITIONS
430 \f
431 Appendix: How to Apply These Terms to Your New Programs
432
433 If you develop a new program, and you want it to be of the greatest
434 possible use to the public, the best way to achieve this is to make it
435 free software which everyone can redistribute and change under these terms.
436
437 To do so, attach the following notices to the program. It is safest
438 to attach them to the start of each source file to most effectively
439 convey the exclusion of warranty; and each file should have at least
440 the "copyright" line and a pointer to where the full notice is found.
441
442 <one line to give the program's name and a brief idea of what it does.>
443 Copyright (C) 19yy <name of author>
444
445 This program is free software; you can redistribute it and/or modify
446 it under the terms of the GNU General Public License as published by
447 the Free Software Foundation; either version 2 of the License, or
448 (at your option) any later version.
449
450 This program is distributed in the hope that it will be useful,
451 but WITHOUT ANY WARRANTY; without even the implied warranty of
452 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
453 GNU General Public License for more details.
454
455 You should have received a copy of the GNU General Public License
456 along with this program; if not, write to the Free Software
457 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
458
459 Also add information on how to contact you by electronic and paper mail.
460
461 If the program is interactive, make it output a short notice like this
462 when it starts in an interactive mode:
463
464 Gnomovision version 69, Copyright (C) 19yy name of author
465 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
466 This is free software, and you are welcome to redistribute it
467 under certain conditions; type `show c' for details.
468
469 The hypothetical commands `show w' and `show c' should show the appropriate
470 parts of the General Public License. Of course, the commands you use may
471 be called something other than `show w' and `show c'; they could even be
472 mouse-clicks or menu items--whatever suits your program.
473
474 You should also get your employer (if you work as a programmer) or your
475 school, if any, to sign a "copyright disclaimer" for the program, if
476 necessary. Here is a sample; alter the names:
477
478 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
479 `Gnomovision' (which makes passes at compilers) written by James Hacker.

483
484 This General Public License does not permit incorporating your program into
485 proprietary programs. If your program is a subroutine library, you may
486 consider it more useful to permit linking proprietary applications with the
487 library. If this is what you want to do, use the GNU Library General
488 Public License instead of this License.

501
502 Preamble
503
504 The licenses for most software are designed to take away your
505 freedom to share and change it. By contrast, the GNU General Public
506 Licenses are intended to guarantee your freedom to share and change
507 free software--to make sure the software is free for all its users.
508
509 This license, the Library General Public License, applies to some
510 specially designated Free Software Foundation software, and to any
511 other libraries whose authors decide to use it. You can use it for
512 your libraries, too.
513
514 When we speak of free software, we are referring to freedom, not
515 price. Our General Public Licenses are designed to make sure that you
516 have the freedom to distribute copies of free software (and charge for
517 this service if you wish), that you receive source code or can get it
518 if you want it, that you can change the software or use pieces of it
519 in new free programs; and that you know you can do these things.
520
521 To protect your rights, we need to make restrictions that forbid
522 anyone to deny you these rights or to ask you to surrender the rights.
523 These restrictions translate to certain responsibilities for you if
524 you distribute copies of the library, or if you modify it.
525
526 For example, if you distribute copies of the library, whether gratis
527 or for a fee, you must give the recipients all the rights that we gave
528 you. You must make sure that they, too, receive or can get the source
529 code. If you link a program with the library, you must provide
530 complete object files to the recipients so that they can relink them
531 with the library, after making changes to the library and recompiling
532 it. And you must show them these terms so they know their rights.
533
534 Our method of protecting your rights has two steps: (1) copyright
535 the library, and (2) offer you this license which gives you legal
536 permission to copy, distribute and/or modify the library.
537
538 Also, for each distributor's protection, we want to make certain
539 that everyone understands that there is no warranty for this free
540 library. If the library is modified by someone else and passed on, we
541 want its recipients to know that what they have is not the original
542 version, so that any problems introduced by others will not reflect on
543 the original authors' reputations.
544 \f
545 Finally, any free program is threatened constantly by software
546 patents. We wish to avoid the danger that companies distributing free
547 software will individually obtain patent licenses, thus in effect
548 transforming the program into proprietary software. To prevent this,
549 we have made it clear that any patent must be licensed for everyone's
550 free use or not licensed at all.
551
552 Most GNU software, including some libraries, is covered by the ordinary
553 GNU General Public License, which was designed for utility programs. This
554 license, the GNU Library General Public License, applies to certain
555 designated libraries. This license is quite different from the ordinary
556 one; be sure to read it in full, and don't assume that anything in it is
557 the same as in the ordinary license.
558
559 The reason we have a separate public license for some libraries is that
560 they blur the distinction we usually make between modifying or adding to a
561 program and simply using it. Linking a program with a library, without
562 changing the library, is in some sense simply using the library, and is
563 analogous to running a utility program or application program. However, in
564 a textual and legal sense, the linked executable is a combined work, a
565 derivative of the original library, and the ordinary General Public License
566 treats it as such.
567
568 Because of this blurred distinction, using the ordinary General
569 Public License for libraries did not effectively promote software
570 sharing, because most developers did not use the libraries. We
571 concluded that weaker conditions might promote sharing better.
572
573 However, unrestricted linking of non-free programs would deprive the
574 users of those programs of all benefit from the free status of the
575 libraries themselves. This Library General Public License is intended to
576 permit developers of non-free programs to use free libraries, while
577 preserving your freedom as a user of such programs to change the free
578 libraries that are incorporated in them. (We have not seen how to achieve
579 this as regards changes in header files, but we have achieved it as regards
580 changes in the actual functions of the Library.) The hope is that this
581 will lead to faster development of free libraries.
582
583 The precise terms and conditions for copying, distribution and
584 modification follow. Pay close attention to the difference between a
585 "work based on the library" and a "work that uses the library". The
586 former contains code derived from the library, while the latter only
587 works together with the library.
588
589 Note that it is possible for a library to be covered by the ordinary
590 General Public License rather than by this special one.
591 \f
592 GNU LIBRARY GENERAL PUBLIC LICENSE
593 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
594
595 0. This License Agreement applies to any software library which
596 contains a notice placed by the copyright holder or other authorized
597 party saying it may be distributed under the terms of this Library
598 General Public License (also called "this License"). Each licensee is
599 addressed as "you".
600
601 A "library" means a collection of software functions and/or data
602 prepared so as to be conveniently linked with application programs
603 (which use some of those functions and data) to form executables.
604
605 The "Library", below, refers to any such software library or work
606 which has been distributed under these terms. A "work based on the
607 Library" means either the Library or any derivative work under
608 copyright law: that is to say, a work containing the Library or a
609 portion of it, either verbatim or with modifications and/or translated
610 straightforwardly into another language. (Hereinafter, translation is
611 included without limitation in the term "modification".)
612
613 "Source code" for a work means the preferred form of the work for
614 making modifications to it. For a library, complete source code means
615 all the source code for all modules it contains, plus any associated
616 interface definition files, plus the scripts used to control compilation
617 and installation of the library.
618
619 Activities other than copying, distribution and modification are not
620 covered by this License; they are outside its scope. The act of
621 running a program using the Library is not restricted, and output from
622 such a program is covered only if its contents constitute a work based
623 on the Library (independent of the use of the Library in a tool for
624 writing it). Whether that is true depends on what the Library does
625 and what the program that uses the Library does.
626
627 1. You may copy and distribute verbatim copies of the Library's
628 complete source code as you receive it, in any medium, provided that
629 you conspicuously and appropriately publish on each copy an
630 appropriate copyright notice and disclaimer of warranty; keep intact
631 all the notices that refer to this License and to the absence of any
632 warranty; and distribute a copy of this License along with the
633 Library.
634
635 You may charge a fee for the physical act of transferring a copy,
636 and you may at your option offer warranty protection in exchange for a
637 fee.
638 \f
639 2. You may modify your copy or copies of the Library or any portion
640 of it, thus forming a work based on the Library, and copy and
641 distribute such modifications or work under the terms of Section 1
642 above, provided that you also meet all of these conditions:
643
644 a) The modified work must itself be a software library.
645
646 b) You must cause the files modified to carry prominent notices
647 stating that you changed the files and the date of any change.
648
649 c) You must cause the whole of the work to be licensed at no
650 charge to all third parties under the terms of this License.
651
652 d) If a facility in the modified Library refers to a function or a
653 table of data to be supplied by an application program that uses
654 the facility, other than as an argument passed when the facility
655 is invoked, then you must make a good faith effort to ensure that,
656 in the event an application does not supply such function or
657 table, the facility still operates, and performs whatever part of
658 its purpose remains meaningful.
659
660 (For example, a function in a library to compute square roots has
661 a purpose that is entirely well-defined independent of the
662 application. Therefore, Subsection 2d requires that any
663 application-supplied function or table used by this function must
664 be optional: if the application does not supply it, the square
665 root function must still compute square roots.)
666
667 These requirements apply to the modified work as a whole. If
668 identifiable sections of that work are not derived from the Library,
669 and can be reasonably considered independent and separate works in
670 themselves, then this License, and its terms, do not apply to those
671 sections when you distribute them as separate works. But when you
672 distribute the same sections as part of a whole which is a work based
673 on the Library, the distribution of the whole must be on the terms of
674 this License, whose permissions for other licensees extend to the
675 entire whole, and thus to each and every part regardless of who wrote
676 it.
677
678 Thus, it is not the intent of this section to claim rights or contest
679 your rights to work written entirely by you; rather, the intent is to
680 exercise the right to control the distribution of derivative or
681 collective works based on the Library.
682
683 In addition, mere aggregation of another work not based on the Library
684 with the Library (or with a work based on the Library) on a volume of
685 a storage or distribution medium does not bring the other work under
686 the scope of this License.
687
688 3. You may opt to apply the terms of the ordinary GNU General Public
689 License instead of this License to a given copy of the Library. To do
690 this, you must alter all the notices that refer to this License, so
691 that they refer to the ordinary GNU General Public License, version 2,
692 instead of to this License. (If a newer version than version 2 of the
693 ordinary GNU General Public License has appeared, then you can specify
694 that version instead if you wish.) Do not make any other change in
695 these notices.
696 \f
697 Once this change is made in a given copy, it is irreversible for
698 that copy, so the ordinary GNU General Public License applies to all
699 subsequent copies and derivative works made from that copy.
700
701 This option is useful when you wish to copy part of the code of
702 the Library into a program that is not a library.
703
704 4. You may copy and distribute the Library (or a portion or
705 derivative of it, under Section 2) in object code or executable form
706 under the terms of Sections 1 and 2 above provided that you accompany
707 it with the complete corresponding machine-readable source code, which
708 must be distributed under the terms of Sections 1 and 2 above on a
709 medium customarily used for software interchange.
710
711 If distribution of object code is made by offering access to copy
712 from a designated place, then offering equivalent access to copy the
713 source code from the same place satisfies the requirement to
714 distribute the source code, even though third parties are not
715 compelled to copy the source along with the object code.
716
717 5. A program that contains no derivative of any portion of the
718 Library, but is designed to work with the Library by being compiled or
719 linked with it, is called a "work that uses the Library". Such a
720 work, in isolation, is not a derivative work of the Library, and
721 therefore falls outside the scope of this License.
722
723 However, linking a "work that uses the Library" with the Library
724 creates an executable that is a derivative of the Library (because it
725 contains portions of the Library), rather than a "work that uses the
726 library". The executable is therefore covered by this License.
727 Section 6 states terms for distribution of such executables.
728
729 When a "work that uses the Library" uses material from a header file
730 that is part of the Library, the object code for the work may be a
731 derivative work of the Library even though the source code is not.
732 Whether this is true is especially significant if the work can be
733 linked without the Library, or if the work is itself a library. The
734 threshold for this to be true is not precisely defined by law.
735
736 If such an object file uses only numerical parameters, data
737 structure layouts and accessors, and small macros and small inline
738 functions (ten lines or less in length), then the use of the object
739 file is unrestricted, regardless of whether it is legally a derivative
740 work. (Executables containing this object code plus portions of the
741 Library will still fall under Section 6.)
742
743 Otherwise, if the work is a derivative of the Library, you may
744 distribute the object code for the work under the terms of Section 6.
745 Any executables containing that work also fall under Section 6,
746 whether or not they are linked directly with the Library itself.
747 \f
748 6. As an exception to the Sections above, you may also compile or
749 link a "work that uses the Library" with the Library to produce a
750 work containing portions of the Library, and distribute that work
751 under terms of your choice, provided that the terms permit
752 modification of the work for the customer's own use and reverse
753 engineering for debugging such modifications.
754
755 You must give prominent notice with each copy of the work that the
756 Library is used in it and that the Library and its use are covered by
757 this License. You must supply a copy of this License. If the work
758 during execution displays copyright notices, you must include the
759 copyright notice for the Library among them, as well as a reference
760 directing the user to the copy of this License. Also, you must do one
761 of these things:
762
763 a) Accompany the work with the complete corresponding
764 machine-readable source code for the Library including whatever
765 changes were used in the work (which must be distributed under
766 Sections 1 and 2 above); and, if the work is an executable linked
767 with the Library, with the complete machine-readable "work that
768 uses the Library", as object code and/or source code, so that the
769 user can modify the Library and then relink to produce a modified
770 executable containing the modified Library. (It is understood
771 that the user who changes the contents of definitions files in the
772 Library will not necessarily be able to recompile the application
773 to use the modified definitions.)
774
775 b) Accompany the work with a written offer, valid for at
776 least three years, to give the same user the materials
777 specified in Subsection 6a, above, for a charge no more
778 than the cost of performing this distribution.
779
780 c) If distribution of the work is made by offering access to copy
781 from a designated place, offer equivalent access to copy the above
782 specified materials from the same place.
783
784 d) Verify that the user has already received a copy of these
785 materials or that you have already sent this user a copy.
786
787 For an executable, the required form of the "work that uses the
788 Library" must include any data and utility programs needed for
789 reproducing the executable from it. However, as a special exception,
790 the source code distributed need not include anything that is normally
791 distributed (in either source or binary form) with the major
792 components (compiler, kernel, and so on) of the operating system on
793 which the executable runs, unless that component itself accompanies
794 the executable.
795
796 It may happen that this requirement contradicts the license
797 restrictions of other proprietary libraries that do not normally
798 accompany the operating system. Such a contradiction means you cannot
799 use both them and the Library together in an executable that you
800 distribute.
801 \f
802 7. You may place library facilities that are a work based on the
803 Library side-by-side in a single library together with other library
804 facilities not covered by this License, and distribute such a combined
805 library, provided that the separate distribution of the work based on
806 the Library and of the other library facilities is otherwise
807 permitted, and provided that you do these two things:
808
809 a) Accompany the combined library with a copy of the same work
810 based on the Library, uncombined with any other library
811 facilities. This must be distributed under the terms of the
812 Sections above.
813
814 b) Give prominent notice with the combined library of the fact
815 that part of it is a work based on the Library, and explaining
816 where to find the accompanying uncombined form of the same work.
817
818 8. You may not copy, modify, sublicense, link with, or distribute
819 the Library except as expressly provided under this License. Any
820 attempt otherwise to copy, modify, sublicense, link with, or
821 distribute the Library is void, and will automatically terminate your
822 rights under this License. However, parties who have received copies,
823 or rights, from you under this License will not have their licenses
824 terminated so long as such parties remain in full compliance.
825
826 9. You are not required to accept this License, since you have not
827 signed it. However, nothing else grants you permission to modify or
828 distribute the Library or its derivative works. These actions are
829 prohibited by law if you do not accept this License. Therefore, by
830 modifying or distributing the Library (or any work based on the
831 Library), you indicate your acceptance of this License to do so, and
832 all its terms and conditions for copying, distributing or modifying
833 the Library or works based on it.
834
835 10. Each time you redistribute the Library (or any work based on the
836 Library), the recipient automatically receives a license from the
837 original licensor to copy, distribute, link with or modify the Library
838 subject to these terms and conditions. You may not impose any further
839 restrictions on the recipients' exercise of the rights granted herein.
840 You are not responsible for enforcing compliance by third parties to
841 this License.
842 \f
843 11. If, as a consequence of a court judgment or allegation of patent
844 infringement or for any other reason (not limited to patent issues),
845 conditions are imposed on you (whether by court order, agreement or
846 otherwise) that contradict the conditions of this License, they do not
847 excuse you from the conditions of this License. If you cannot
848 distribute so as to satisfy simultaneously your obligations under this
849 License and any other pertinent obligations, then as a consequence you
850 may not distribute the Library at all. For example, if a patent
851 license would not permit royalty-free redistribution of the Library by
852 all those who receive copies directly or indirectly through you, then
853 the only way you could satisfy both it and this License would be to
854 refrain entirely from distribution of the Library.
855
856 If any portion of this section is held invalid or unenforceable under any
857 particular circumstance, the balance of the section is intended to apply,
858 and the section as a whole is intended to apply in other circumstances.
859
860 It is not the purpose of this section to induce you to infringe any
861 patents or other property right claims or to contest validity of any
862 such claims; this section has the sole purpose of protecting the
863 integrity of the free software distribution system which is
864 implemented by public license practices. Many people have made
865 generous contributions to the wide range of software distributed
866 through that system in reliance on consistent application of that
867 system; it is up to the author/donor to decide if he or she is willing
868 to distribute software through any other system and a licensee cannot
869 impose that choice.
870
871 This section is intended to make thoroughly clear what is believed to
872 be a consequence of the rest of this License.
873
874 12. If the distribution and/or use of the Library is restricted in
875 certain countries either by patents or by copyrighted interfaces, the
876 original copyright holder who places the Library under this License may add
877 an explicit geographical distribution limitation excluding those countries,
878 so that distribution is permitted only in or among countries not thus
879 excluded. In such case, this License incorporates the limitation as if
880 written in the body of this License.
881
882 13. The Free Software Foundation may publish revised and/or new
883 versions of the Library General Public License from time to time.
884 Such new versions will be similar in spirit to the present version,
885 but may differ in detail to address new problems or concerns.
886
887 Each version is given a distinguishing version number. If the Library
888 specifies a version number of this License which applies to it and
889 "any later version", you have the option of following the terms and
890 conditions either of that version or of any later version published by
891 the Free Software Foundation. If the Library does not specify a
892 license version number, you may choose any version ever published by
893 the Free Software Foundation.
894 \f
895 14. If you wish to incorporate parts of the Library into other free
896 programs whose distribution conditions are incompatible with these,
897 write to the author to ask for permission. For software which is
898 copyrighted by the Free Software Foundation, write to the Free
899 Software Foundation; we sometimes make exceptions for this. Our
900 decision will be guided by the two goals of preserving the free status
901 of all derivatives of our free software and of promoting the sharing
902 and reuse of software generally.
903
904 NO WARRANTY
905
906 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
907 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
908 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
909 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
910 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
911 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
912 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
913 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
914 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
915
916 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
917 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
918 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
919 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
920 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
921 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
922 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
923 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
924 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
925 DAMAGES.
926
927 END OF TERMS AND CONDITIONS
928 \f
929 Appendix: How to Apply These Terms to Your New Libraries
930
931 If you develop a new library, and you want it to be of the greatest
932 possible use to the public, we recommend making it free software that
933 everyone can redistribute and change. You can do so by permitting
934 redistribution under these terms (or, alternatively, under the terms of the
935 ordinary General Public License).
936
937 To apply these terms, attach the following notices to the library. It is
938 safest to attach them to the start of each source file to most effectively
939 convey the exclusion of warranty; and each file should have at least the
940 "copyright" line and a pointer to where the full notice is found.
941
942 <one line to give the library's name and a brief idea of what it does.>
943 Copyright (C) <year> <name of author>
944
945 This library is free software; you can redistribute it and/or
946 modify it under the terms of the GNU Library General Public
947 License as published by the Free Software Foundation; either
948 version 2 of the License, or (at your option) any later version.
949
950 This library is distributed in the hope that it will be useful,
951 but WITHOUT ANY WARRANTY; without even the implied warranty of
952 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
953 Library General Public License for more details.
954
955 You should have received a copy of the GNU Library General Public
956 License along with this library; if not, write to the Free
957 Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
958
959 Also add information on how to contact you by electronic and paper mail.
960
961 You should also get your employer (if you work as a programmer) or your
962 school, if any, to sign a "copyright disclaimer" for the library, if
963 necessary. Here is a sample; alter the names:
