12 | INTRODUCTION | |
13 | ||
14 | The Common UNIX Printing System(tm), ("CUPS(tm)"), is provided | |
15 | under the GNU General Public License ("GPL") and GNU Library | |
16 | General Public License ("LGPL"), Version 2, with exceptions for | |
17 | Apple operating systems and the OpenSSL toolkit. A copy of the | |
18 | exceptions and licenses follow this introduction. | |
19 | ||
26d47ec6 | 20 | The GNU LGPL applies to the CUPS and CUPS Imaging libraries |
21 | located in the "cups" and "filter" subdirectories of the CUPS | |
22 | source distribution and in the "cups" include directory and | |
23 | library files in the binary distributions. The GNU GPL applies to | |
24 | the remainder of the CUPS distribution, including the "pdftops" | |
25 | filter which is based upon Xpdf. | |
ef416fc2 | 26 | |
27 | For those not familiar with the GNU GPL, the license basically | |
28 | allows you to: | |
29 | ||
30 | - Use the CUPS software at no charge. | |
31 | - Distribute verbatim copies of the software in source or | |
32 | binary form. | |
33 | - Sell verbatim copies of the software for a media fee, or | |
34 | sell support for the software. | |
ef416fc2 | 35 | |
36 | What this license *does not* allow you to do is make changes or | |
37 | add features to CUPS and then sell a binary distribution without | |
26d47ec6 | 38 | source code. You must provide source for any changes or additions |
39 | to the software, and all code must be provided under the GPL or | |
40 | LGPL as appropriate. The only exceptions to this are the portions | |
41 | of the CUPS software covered by the Apple operating system | |
42 | license exceptions outlined later in this license agreement. | |
ef416fc2 | 43 | |
44 | The GNU LGPL relaxes the "link-to" restriction, allowing you to | |
26d47ec6 | 45 | develop applications that use the CUPS and CUPS Imaging libraries |
46 | under other licenses and/or conditions as appropriate for your | |
47 | application, driver, or filter. | |
ef416fc2 | 48 | |
49 | ||
50 | LICENSE EXCEPTIONS | |
51 | ||
52 | In addition, as the copyright holder of CUPS, Easy Software | |
53 | Products grants the following special exceptions: | |
54 | ||
55 | 1. Apple Operating System Development License Exception; | |
56 | ||
57 | a. Software that is developed by any person or entity | |
58 | for an Apple Operating System ("Apple OS-Developed | |
59 | Software"), including but not limited to Apple and | |
60 | third party printer drivers, filters, and backends | |
61 | for an Apple Operating System, that is linked to the | |
62 | CUPS imaging library or based on any sample filters | |
63 | or backends provided with CUPS shall not be | |
64 | considered to be a derivative work or collective work | |
65 | based on the CUPS program and is exempt from the | |
66 | mandatory source code release clauses of the GNU GPL. | |
67 | You may therefore distribute linked combinations of | |
68 | the CUPS imaging library with Apple OS-Developed | |
69 | Software without releasing the source code of the | |
70 | Apple OS-Developed Software. You may also use sample | |
71 | filters and backends provided with CUPS to develop | |
72 | Apple OS-Developed Software without releasing the | |
73 | source code of the Apple OS-Developed Software. | |
74 | ||
75 | b. An Apple Operating System means any operating system | |
76 | software developed and/or marketed by Apple Computer, | |
77 | Inc., including but not limited to all existing | |
78 | releases and versions of Apple's Darwin, Mac OS X, | |
79 | and Mac OS X Server products and all follow-on | |
80 | releases and future versions thereof. | |
81 | ||
82 | c. This exception is only available for Apple | |
83 | OS-Developed Software and does not apply to software | |
84 | that is distributed for use on other operating | |
85 | systems. | |
86 | ||
87 | d. All CUPS software that falls under this license | |
88 | exception have the following text at the top of each | |
89 | source file: | |
90 | ||
91 | This file is subject to the Apple OS-Developed | |
92 | Software exception. | |
93 | ||
94 | 2. OpenSSL Toolkit License Exception; | |
95 | ||
96 | a. Easy Software Products explicitly allows the | |
97 | compilation and distribution of the CUPS software | |
98 | with the OpenSSL Toolkit. | |
99 | ||
100 | No developer is required to provide these exceptions in a | |
101 | derived work. | |
102 | ||
103 | ||
104 | TRADEMARKS | |
105 | ||
106 | Easy Software Products has trademarked the Common UNIX Printing | |
107 | System, CUPS, and CUPS logo. You may use these names and logos | |
108 | in any direct port or binary distribution of CUPS. Please | |
109 | contact Easy Software Products for written permission to use | |
110 | them in derivative products. Our intention is to protect the | |
111 | value of these trademarks and ensure that any derivative product | |
112 | meets the same high-quality standards as the original. | |
113 | ||
114 | ||
115 | BINARY DISTRIBUTION RIGHTS | |
116 | ||
117 | Easy Software Products also sells rights to the CUPS source code | |
118 | under a binary distribution license for vendors that are unable | |
26d47ec6 | 119 | to release source code for their additions and modifications to |
120 | CUPS under the GNU GPL and LGPL. For information please contact | |
121 | us at the address shown above. | |
ef416fc2 | 122 | |
123 | The Common UNIX Printing System provides a "pdftops" filter that | |
124 | is based on the Xpdf software. For binary distribution licensing | |
125 | of this software, please contact: | |

140 | GNU GENERAL PUBLIC LICENSE | |
141 | Version 2, June 1991 | |
142 | ||
143 | Copyright (C) 1989, 1991 Free Software Foundation, Inc. | |
144 | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | |
145 | Everyone is permitted to copy and distribute verbatim copies | |
146 | of this license document, but changing it is not allowed. | |
147 | ||
148 | Preamble | |
149 | ||
150 | The licenses for most software are designed to take away your | |
151 | freedom to share and change it. By contrast, the GNU General Public | |
152 | License is intended to guarantee your freedom to share and change free | |
153 | software--to make sure the software is free for all its users. This | |
154 | General Public License applies to most of the Free Software | |
155 | Foundation's software and to any other program whose authors commit to | |
156 | using it. (Some other Free Software Foundation software is covered by | |
157 | the GNU Library General Public License instead.) You can apply it to | |
158 | your programs, too. | |
159 | ||
160 | When we speak of free software, we are referring to freedom, not | |
161 | price. Our General Public Licenses are designed to make sure that you | |
162 | have the freedom to distribute copies of free software (and charge for | |
163 | this service if you wish), that you receive source code or can get it | |
164 | if you want it, that you can change the software or use pieces of it | |
165 | in new free programs; and that you know you can do these things. | |
166 | ||
167 | To protect your rights, we need to make restrictions that forbid | |
168 | anyone to deny you these rights or to ask you to surrender the rights. | |
169 | These restrictions translate to certain responsibilities for you if you | |
170 | distribute copies of the software, or if you modify it. | |
171 | ||
172 | For example, if you distribute copies of such a program, whether | |
173 | gratis or for a fee, you must give the recipients all the rights that | |
174 | you have. You must make sure that they, too, receive or can get the | |
175 | source code. And you must show them these terms so they know their | |
176 | rights. | |
177 | ||
178 | We protect your rights with two steps: (1) copyright the software, and | |
179 | (2) offer you this license which gives you legal permission to copy, | |
180 | distribute and/or modify the software. | |
181 | ||
182 | Also, for each author's protection and ours, we want to make certain | |
183 | that everyone understands that there is no warranty for this free | |
184 | software. If the software is modified by someone else and passed on, we | |
185 | want its recipients to know that what they have is not the original, so | |
186 | that any problems introduced by others will not reflect on the original | |
187 | authors' reputations. | |
188 | ||
189 | Finally, any free program is threatened constantly by software | |
190 | patents. We wish to avoid the danger that redistributors of a free | |
191 | program will individually obtain patent licenses, in effect making the | |
192 | program proprietary. To prevent this, we have made it clear that any | |
193 | patent must be licensed for everyone's free use or not licensed at all. | |
194 | ||
195 | The precise terms and conditions for copying, distribution and | |
196 | modification follow. | |
197 | \f | |
198 | GNU GENERAL PUBLIC LICENSE | |
199 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
200 | ||
201 | 0. This License applies to any program or other work which contains | |
202 | a notice placed by the copyright holder saying it may be distributed | |
203 | under the terms of this General Public License. The "Program", below, | |
204 | refers to any such program or work, and a "work based on the Program" | |
205 | means either the Program or any derivative work under copyright law: | |
206 | that is to say, a work containing the Program or a portion of it, | |
207 | either verbatim or with modifications and/or translated into another | |
208 | language. (Hereinafter, translation is included without limitation in | |
209 | the term "modification".) Each licensee is addressed as "you". | |
210 | ||
211 | Activities other than copying, distribution and modification are not | |
212 | covered by this License; they are outside its scope. The act of | |
213 | running the Program is not restricted, and the output from the Program | |
214 | is covered only if its contents constitute a work based on the | |
215 | Program (independent of having been made by running the Program). | |
216 | Whether that is true depends on what the Program does. | |
217 | ||
218 | 1. You may copy and distribute verbatim copies of the Program's | |
219 | source code as you receive it, in any medium, provided that you | |
220 | conspicuously and appropriately publish on each copy an appropriate | |
221 | copyright notice and disclaimer of warranty; keep intact all the | |
222 | notices that refer to this License and to the absence of any warranty; | |
223 | and give any other recipients of the Program a copy of this License | |
224 | along with the Program. | |
225 | ||
226 | You may charge a fee for the physical act of transferring a copy, and | |
227 | you may at your option offer warranty protection in exchange for a fee. | |
228 | ||
229 | 2. You may modify your copy or copies of the Program or any portion | |
230 | of it, thus forming a work based on the Program, and copy and | |
231 | distribute such modifications or work under the terms of Section 1 | |
232 | above, provided that you also meet all of these conditions: | |
233 | ||
234 | a) You must cause the modified files to carry prominent notices | |
235 | stating that you changed the files and the date of any change. | |
236 | ||
237 | b) You must cause any work that you distribute or publish, that in | |
238 | whole or in part contains or is derived from the Program or any | |
239 | part thereof, to be licensed as a whole at no charge to all third | |
240 | parties under the terms of this License. | |
241 | ||
242 | c) If the modified program normally reads commands interactively | |
243 | when run, you must cause it, when started running for such | |
244 | interactive use in the most ordinary way, to print or display an | |
245 | announcement including an appropriate copyright notice and a | |
246 | notice that there is no warranty (or else, saying that you provide | |
247 | a warranty) and that users may redistribute the program under | |
248 | these conditions, and telling the user how to view a copy of this | |
249 | License. (Exception: if the Program itself is interactive but | |
250 | does not normally print such an announcement, your work based on | |
251 | the Program is not required to print an announcement.) | |
252 | \f | |
253 | These requirements apply to the modified work as a whole. If | |
254 | identifiable sections of that work are not derived from the Program, | |
255 | and can be reasonably considered independent and separate works in | |
256 | themselves, then this License, and its terms, do not apply to those | |
257 | sections when you distribute them as separate works. But when you | |
258 | distribute the same sections as part of a whole which is a work based | |
259 | on the Program, the distribution of the whole must be on the terms of | |
260 | this License, whose permissions for other licensees extend to the | |
261 | entire whole, and thus to each and every part regardless of who wrote it. | |
262 | ||
263 | Thus, it is not the intent of this section to claim rights or contest | |
264 | your rights to work written entirely by you; rather, the intent is to | |
265 | exercise the right to control the distribution of derivative or | |
266 | collective works based on the Program. | |
267 | ||
268 | In addition, mere aggregation of another work not based on the Program | |
269 | with the Program (or with a work based on the Program) on a volume of | |
270 | a storage or distribution medium does not bring the other work under | |
271 | the scope of this License. | |
272 | ||
273 | 3. You may copy and distribute the Program (or a work based on it, | |
274 | under Section 2) in object code or executable form under the terms of | |
275 | Sections 1 and 2 above provided that you also do one of the following: | |
276 | ||
277 | a) Accompany it with the complete corresponding machine-readable | |
278 | source code, which must be distributed under the terms of Sections | |
279 | 1 and 2 above on a medium customarily used for software interchange; or, | |
280 | ||
281 | b) Accompany it with a written offer, valid for at least three | |
282 | years, to give any third party, for a charge no more than your | |
283 | cost of physically performing source distribution, a complete | |
284 | machine-readable copy of the corresponding source code, to be | |
285 | distributed under the terms of Sections 1 and 2 above on a medium | |
286 | customarily used for software interchange; or, | |
287 | ||
288 | c) Accompany it with the information you received as to the offer | |
289 | to distribute corresponding source code. (This alternative is | |
290 | allowed only for noncommercial distribution and only if you | |
291 | received the program in object code or executable form with such | |
292 | an offer, in accord with Subsection b above.) | |
293 | ||
294 | The source code for a work means the preferred form of the work for | |
295 | making modifications to it. For an executable work, complete source | |
296 | code means all the source code for all modules it contains, plus any | |
297 | associated interface definition files, plus the scripts used to | |
298 | control compilation and installation of the executable. However, as a | |
299 | special exception, the source code distributed need not include | |
300 | anything that is normally distributed (in either source or binary | |
301 | form) with the major components (compiler, kernel, and so on) of the | |
302 | operating system on which the executable runs, unless that component | |
303 | itself accompanies the executable. | |
304 | ||
305 | If distribution of executable or object code is made by offering | |
306 | access to copy from a designated place, then offering equivalent | |
307 | access to copy the source code from the same place counts as | |
308 | distribution of the source code, even though third parties are not | |
309 | compelled to copy the source along with the object code. | |
310 | \f | |
311 | 4. You may not copy, modify, sublicense, or distribute the Program | |
312 | except as expressly provided under this License. Any attempt | |
313 | otherwise to copy, modify, sublicense or distribute the Program is | |
314 | void, and will automatically terminate your rights under this License. | |
315 | However, parties who have received copies, or rights, from you under | |
316 | this License will not have their licenses terminated so long as such | |
317 | parties remain in full compliance. | |
318 | ||
319 | 5. You are not required to accept this License, since you have not | |
320 | signed it. However, nothing else grants you permission to modify or | |
321 | distribute the Program or its derivative works. These actions are | |
322 | prohibited by law if you do not accept this License. Therefore, by | |
323 | modifying or distributing the Program (or any work based on the | |
324 | Program), you indicate your acceptance of this License to do so, and | |
325 | all its terms and conditions for copying, distributing or modifying | |
326 | the Program or works based on it. | |
327 | ||
328 | 6. Each time you redistribute the Program (or any work based on the | |
329 | Program), the recipient automatically receives a license from the | |
330 | original licensor to copy, distribute or modify the Program subject to | |
331 | these terms and conditions. You may not impose any further | |
332 | restrictions on the recipients' exercise of the rights granted herein. | |
333 | You are not responsible for enforcing compliance by third parties to | |
334 | this License. | |
335 | ||
336 | 7. If, as a consequence of a court judgment or allegation of patent | |
337 | infringement or for any other reason (not limited to patent issues), | |
338 | conditions are imposed on you (whether by court order, agreement or | |
339 | otherwise) that contradict the conditions of this License, they do not | |
340 | excuse you from the conditions of this License. If you cannot | |
341 | distribute so as to satisfy simultaneously your obligations under this | |
342 | License and any other pertinent obligations, then as a consequence you | |
343 | may not distribute the Program at all. For example, if a patent | |
344 | license would not permit royalty-free redistribution of the Program by | |
345 | all those who receive copies directly or indirectly through you, then | |
346 | the only way you could satisfy both it and this License would be to | |
347 | refrain entirely from distribution of the Program. | |
348 | ||
349 | If any portion of this section is held invalid or unenforceable under | |
350 | any particular circumstance, the balance of the section is intended to | |
351 | apply and the section as a whole is intended to apply in other | |
352 | circumstances. | |
353 | ||
354 | It is not the purpose of this section to induce you to infringe any | |
355 | patents or other property right claims or to contest validity of any | |
356 | such claims; this section has the sole purpose of protecting the | |
357 | integrity of the free software distribution system, which is | |
358 | implemented by public license practices. Many people have made | |
359 | generous contributions to the wide range of software distributed | |
360 | through that system in reliance on consistent application of that | |
361 | system; it is up to the author/donor to decide if he or she is willing | |
362 | to distribute software through any other system and a licensee cannot | |
363 | impose that choice. | |
364 | ||
365 | This section is intended to make thoroughly clear what is believed to | |
366 | be a consequence of the rest of this License. | |
367 | \f | |
368 | 8. If the distribution and/or use of the Program is restricted in | |
369 | certain countries either by patents or by copyrighted interfaces, the | |
370 | original copyright holder who places the Program under this License | |
371 | may add an explicit geographical distribution limitation excluding | |
372 | those countries, so that distribution is permitted only in or among | |
373 | countries not thus excluded. In such case, this License incorporates | |
374 | the limitation as if written in the body of this License. | |
375 | ||
376 | 9. The Free Software Foundation may publish revised and/or new versions | |
377 | of the General Public License from time to time. Such new versions will | |
378 | be similar in spirit to the present version, but may differ in detail to | |
379 | address new problems or concerns. | |
380 | ||
381 | Each version is given a distinguishing version number. If the Program | |
382 | specifies a version number of this License which applies to it and "any | |
383 | later version", you have the option of following the terms and conditions | |
384 | either of that version or of any later version published by the Free | |
385 | Software Foundation. If the Program does not specify a version number of | |
386 | this License, you may choose any version ever published by the Free Software | |
387 | Foundation. | |
388 | ||
389 | 10. If you wish to incorporate parts of the Program into other free | |
390 | programs whose distribution conditions are different, write to the author | |
391 | to ask for permission. For software which is copyrighted by the Free | |
392 | Software Foundation, write to the Free Software Foundation; we sometimes | |
393 | make exceptions for this. Our decision will be guided by the two goals | |
394 | of preserving the free status of all derivatives of our free software and | |
395 | of promoting the sharing and reuse of software generally. | |
396 | ||
397 | NO WARRANTY | |
398 | ||
399 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | |
400 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | |
401 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
402 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
403 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
404 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |
405 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
406 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | |
407 | REPAIR OR CORRECTION. | |
408 | ||
409 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
410 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
411 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
412 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | |
413 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | |
414 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | |
415 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | |
416 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
417 | POSSIBILITY OF SUCH DAMAGES. | |
418 | ||
419 | END OF TERMS AND CONDITIONS | |
420 | \f | |
421 | Appendix: How to Apply These Terms to Your New Programs | |
422 | ||
423 | If you develop a new program, and you want it to be of the greatest | |
424 | possible use to the public, the best way to achieve this is to make it | |
425 | free software which everyone can redistribute and change under these terms. | |
426 | ||
427 | To do so, attach the following notices to the program. It is safest | |
428 | to attach them to the start of each source file to most effectively | |
429 | convey the exclusion of warranty; and each file should have at least | |
430 | the "copyright" line and a pointer to where the full notice is found. | |
431 | ||
432 | <one line to give the program's name and a brief idea of what it does.> | |
433 | Copyright (C) 19yy <name of author> | |
434 | ||
435 | This program is free software; you can redistribute it and/or modify | |
436 | it under the terms of the GNU General Public License as published by | |
437 | the Free Software Foundation; either version 2 of the License, or | |
438 | (at your option) any later version. | |
439 | ||
440 | This program is distributed in the hope that it will be useful, | |
441 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
442 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
443 | GNU General Public License for more details. | |
444 | ||
445 | You should have received a copy of the GNU General Public License | |
446 | along with this program; if not, write to the Free Software | |

459 | The hypothetical commands `show w' and `show c' should show the appropriate | |

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

482 | ||
483 | Copyright (C) 1991 Free Software Foundation, Inc. | |
484 | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | |
485 | ||
486 | Everyone is permitted to copy and distribute verbatim copies | |
487 | of this license document, but changing it is not allowed. | |
488 | ||
489 | [This is the first released version of the library GPL. It is | |
490 | numbered 2 because it goes with version 2 of the ordinary GPL.] | |
491 | ||
492 | Preamble | |
493 | ||
494 | The licenses for most software are designed to take away your | |
495 | freedom to share and change it. By contrast, the GNU General Public | |
496 | Licenses are intended to guarantee your freedom to share and change | |
497 | free software--to make sure the software is free for all its users. | |
498 | ||
499 | This license, the Library General Public License, applies to some | |
500 | specially designated Free Software Foundation software, and to any | |
501 | other libraries whose authors decide to use it. You can use it for | |
502 | your libraries, too. | |
503 | ||
504 | When we speak of free software, we are referring to freedom, not | |
505 | price. Our General Public Licenses are designed to make sure that you | |
506 | have the freedom to distribute copies of free software (and charge for | |
507 | this service if you wish), that you receive source code or can get it | |
508 | if you want it, that you can change the software or use pieces of it | |
509 | in new free programs; and that you know you can do these things. | |
510 | ||
511 | To protect your rights, we need to make restrictions that forbid | |
512 | anyone to deny you these rights or to ask you to surrender the rights. | |
513 | These restrictions translate to certain responsibilities for you if | |
514 | you distribute copies of the library, or if you modify it. | |
515 | ||
516 | For example, if you distribute copies of the library, whether gratis | |
517 | or for a fee, you must give the recipients all the rights that we gave | |
518 | you. You must make sure that they, too, receive or can get the source | |
519 | code. If you link a program with the library, you must provide | |
520 | complete object files to the recipients so that they can relink them | |
521 | with the library, after making changes to the library and recompiling | |
522 | it. And you must show them these terms so they know their rights. | |
523 | ||
524 | Our method of protecting your rights has two steps: (1) copyright | |
525 | the library, and (2) offer you this license which gives you legal | |
526 | permission to copy, distribute and/or modify the library. | |
527 | ||
528 | Also, for each distributor's protection, we want to make certain | |
529 | that everyone understands that there is no warranty for this free | |
530 | library. If the library is modified by someone else and passed on, we | |
531 | want its recipients to know that what they have is not the original | |
532 | version, so that any problems introduced by others will not reflect on | |
533 | the original authors' reputations. | |
534 | \f | |
535 | Finally, any free program is threatened constantly by software | |
536 | patents. We wish to avoid the danger that companies distributing free | |
537 | software will individually obtain patent licenses, thus in effect | |
538 | transforming the program into proprietary software. To prevent this, | |
539 | we have made it clear that any patent must be licensed for everyone's | |
540 | free use or not licensed at all. | |
541 | ||
542 | Most GNU software, including some libraries, is covered by the ordinary | |
543 | GNU General Public License, which was designed for utility programs. This | |
544 | license, the GNU Library General Public License, applies to certain | |
545 | designated libraries. This license is quite different from the ordinary | |
546 | one; be sure to read it in full, and don't assume that anything in it is | |
547 | the same as in the ordinary license. | |
548 | ||
549 | The reason we have a separate public license for some libraries is that | |
550 | they blur the distinction we usually make between modifying or adding to a | |
551 | program and simply using it. Linking a program with a library, without | |
552 | changing the library, is in some sense simply using the library, and is | |
553 | analogous to running a utility program or application program. However, in | |
554 | a textual and legal sense, the linked executable is a combined work, a | |
555 | derivative of the original library, and the ordinary General Public License | |
556 | treats it as such. | |
557 | ||
558 | Because of this blurred distinction, using the ordinary General | |
559 | Public License for libraries did not effectively promote software | |
560 | sharing, because most developers did not use the libraries. We | |
561 | concluded that weaker conditions might promote sharing better. | |
562 | ||
563 | However, unrestricted linking of non-free programs would deprive the | |
564 | users of those programs of all benefit from the free status of the | |
565 | libraries themselves. This Library General Public License is intended to | |
566 | permit developers of non-free programs to use free libraries, while | |
567 | preserving your freedom as a user of such programs to change the free | |
568 | libraries that are incorporated in them. (We have not seen how to achieve | |
569 | this as regards changes in header files, but we have achieved it as regards | |
570 | changes in the actual functions of the Library.) The hope is that this | |
571 | will lead to faster development of free libraries. | |
572 | ||
573 | The precise terms and conditions for copying, distribution and | |
574 | modification follow. Pay close attention to the difference between a | |
575 | "work based on the library" and a "work that uses the library". The | |
576 | former contains code derived from the library, while the latter only | |
577 | works together with the library. | |
578 | ||
579 | Note that it is possible for a library to be covered by the ordinary | |
580 | General Public License rather than by this special one. | |
581 | \f | |
582 | GNU LIBRARY GENERAL PUBLIC LICENSE | |
583 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
584 | ||
585 | 0. This License Agreement applies to any software library which | |
586 | contains a notice placed by the copyright holder or other authorized | |
587 | party saying it may be distributed under the terms of this Library | |
588 | General Public License (also called "this License"). Each licensee is | |
589 | addressed as "you". | |
590 | ||
591 | A "library" means a collection of software functions and/or data | |
592 | prepared so as to be conveniently linked with application programs | |
593 | (which use some of those functions and data) to form executables. | |
594 | ||
595 | The "Library", below, refers to any such software library or work | |
596 | which has been distributed under these terms. A "work based on the | |
597 | Library" means either the Library or any derivative work under | |
598 | copyright law: that is to say, a work containing the Library or a | |
599 | portion of it, either verbatim or with modifications and/or translated | |
600 | straightforwardly into another language. (Hereinafter, translation is | |
601 | included without limitation in the term "modification".) | |
602 | ||
603 | "Source code" for a work means the preferred form of the work for | |
604 | making modifications to it. For a library, complete source code means | |
605 | all the source code for all modules it contains, plus any associated | |
606 | interface definition files, plus the scripts used to control compilation | |
607 | and installation of the library. | |
608 | ||
609 | Activities other than copying, distribution and modification are not | |
610 | covered by this License; they are outside its scope. The act of | |
611 | running a program using the Library is not restricted, and output from | |
612 | such a program is covered only if its contents constitute a work based | |
613 | on the Library (independent of the use of the Library in a tool for | |
614 | writing it). Whether that is true depends on what the Library does | |
615 | and what the program that uses the Library does. | |
616 | ||
617 | 1. You may copy and distribute verbatim copies of the Library's | |
618 | complete source code as you receive it, in any medium, provided that | |
619 | you conspicuously and appropriately publish on each copy an | |
620 | appropriate copyright notice and disclaimer of warranty; keep intact | |
621 | all the notices that refer to this License and to the absence of any | |
622 | warranty; and distribute a copy of this License along with the | |
623 | Library. | |
624 | ||
625 | You may charge a fee for the physical act of transferring a copy, | |
626 | and you may at your option offer warranty protection in exchange for a | |
627 | fee. | |
628 | \f | |
629 | 2. You may modify your copy or copies of the Library or any portion | |
630 | of it, thus forming a work based on the Library, and copy and | |
631 | distribute such modifications or work under the terms of Section 1 | |
632 | above, provided that you also meet all of these conditions: | |
633 | ||
634 | a) The modified work must itself be a software library. | |
635 | ||
636 | b) You must cause the files modified to carry prominent notices | |
637 | stating that you changed the files and the date of any change. | |
638 | ||
639 | c) You must cause the whole of the work to be licensed at no | |
640 | charge to all third parties under the terms of this License. | |
641 | ||
642 | d) If a facility in the modified Library refers to a function or a | |
643 | table of data to be supplied by an application program that uses | |
644 | the facility, other than as an argument passed when the facility | |
645 | is invoked, then you must make a good faith effort to ensure that, | |
646 | in the event an application does not supply such function or | |
647 | table, the facility still operates, and performs whatever part of | |
648 | its purpose remains meaningful. | |
649 | ||
650 | (For example, a function in a library to compute square roots has | |
651 | a purpose that is entirely well-defined independent of the | |
652 | application. Therefore, Subsection 2d requires that any | |
653 | application-supplied function or table used by this function must | |
654 | be optional: if the application does not supply it, the square | |
655 | root function must still compute square roots.) | |
656 | ||
657 | These requirements apply to the modified work as a whole. If | |
658 | identifiable sections of that work are not derived from the Library, | |
659 | and can be reasonably considered independent and separate works in | |
660 | themselves, then this License, and its terms, do not apply to those | |
661 | sections when you distribute them as separate works. But when you | |
662 | distribute the same sections as part of a whole which is a work based | |
663 | on the Library, the distribution of the whole must be on the terms of | |
664 | this License, whose permissions for other licensees extend to the | |
665 | entire whole, and thus to each and every part regardless of who wrote | |
666 | it. | |
667 | ||
668 | Thus, it is not the intent of this section to claim rights or contest | |
669 | your rights to work written entirely by you; rather, the intent is to | |
670 | exercise the right to control the distribution of derivative or | |
671 | collective works based on the Library. | |
672 | ||
673 | In addition, mere aggregation of another work not based on the Library | |
674 | with the Library (or with a work based on the Library) on a volume of | |
675 | a storage or distribution medium does not bring the other work under | |
676 | the scope of this License. | |
677 | ||
678 | 3. You may opt to apply the terms of the ordinary GNU General Public | |
679 | License instead of this License to a given copy of the Library. To do | |
680 | this, you must alter all the notices that refer to this License, so | |
681 | that they refer to the ordinary GNU General Public License, version 2, | |
682 | instead of to this License. (If a newer version than version 2 of the | |
683 | ordinary GNU General Public License has appeared, then you can specify | |
684 | that version instead if you wish.) Do not make any other change in | |
685 | these notices. | |
686 | \f | |
687 | Once this change is made in a given copy, it is irreversible for | |
688 | that copy, so the ordinary GNU General Public License applies to all | |
689 | subsequent copies and derivative works made from that copy. | |
690 | ||
691 | This option is useful when you wish to copy part of the code of | |
692 | the Library into a program that is not a library. | |
693 | ||
694 | 4. You may copy and distribute the Library (or a portion or | |
695 | derivative of it, under Section 2) in object code or executable form | |
696 | under the terms of Sections 1 and 2 above provided that you accompany | |
697 | it with the complete corresponding machine-readable source code, which | |
698 | must be distributed under the terms of Sections 1 and 2 above on a | |
699 | medium customarily used for software interchange. | |
700 | ||
701 | If distribution of object code is made by offering access to copy | |
702 | from a designated place, then offering equivalent access to copy the | |
703 | source code from the same place satisfies the requirement to | |
704 | distribute the source code, even though third parties are not | |
705 | compelled to copy the source along with the object code. | |
706 | ||
707 | 5. A program that contains no derivative of any portion of the | |
708 | Library, but is designed to work with the Library by being compiled or | |
709 | linked with it, is called a "work that uses the Library". Such a | |
710 | work, in isolation, is not a derivative work of the Library, and | |
711 | therefore falls outside the scope of this License. | |
712 | ||
713 | However, linking a "work that uses the Library" with the Library | |
714 | creates an executable that is a derivative of the Library (because it | |
715 | contains portions of the Library), rather than a "work that uses the | |
716 | library". The executable is therefore covered by this License. | |
717 | Section 6 states terms for distribution of such executables. | |
718 | ||
719 | When a "work that uses the Library" uses material from a header file | |
720 | that is part of the Library, the object code for the work may be a | |
721 | derivative work of the Library even though the source code is not. | |
722 | Whether this is true is especially significant if the work can be | |
723 | linked without the Library, or if the work is itself a library. The | |
724 | threshold for this to be true is not precisely defined by law. | |
725 | ||
726 | If such an object file uses only numerical parameters, data | |
727 | structure layouts and accessors, and small macros and small inline | |
728 | functions (ten lines or less in length), then the use of the object | |
729 | file is unrestricted, regardless of whether it is legally a derivative | |
730 | work. (Executables containing this object code plus portions of the | |
731 | Library will still fall under Section 6.) | |
732 | ||
733 | Otherwise, if the work is a derivative of the Library, you may | |
734 | distribute the object code for the work under the terms of Section 6. | |
735 | Any executables containing that work also fall under Section 6, | |
736 | whether or not they are linked directly with the Library itself. | |
737 | \f | |
738 | 6. As an exception to the Sections above, you may also compile or | |
739 | link a "work that uses the Library" with the Library to produce a | |
740 | work containing portions of the Library, and distribute that work | |
741 | under terms of your choice, provided that the terms permit | |
742 | modification of the work for the customer's own use and reverse | |
743 | engineering for debugging such modifications. | |
744 | ||
745 | You must give prominent notice with each copy of the work that the | |
746 | Library is used in it and that the Library and its use are covered by | |
747 | this License. You must supply a copy of this License. If the work | |
748 | during execution displays copyright notices, you must include the | |
749 | copyright notice for the Library among them, as well as a reference | |
750 | directing the user to the copy of this License. Also, you must do one | |
751 | of these things: | |
752 | ||
753 | a) Accompany the work with the complete corresponding | |
754 | machine-readable source code for the Library including whatever | |
755 | changes were used in the work (which must be distributed under | |
756 | Sections 1 and 2 above); and, if the work is an executable linked | |
757 | with the Library, with the complete machine-readable "work that | |
758 | uses the Library", as object code and/or source code, so that the | |
759 | user can modify the Library and then relink to produce a modified | |
760 | executable containing the modified Library. (It is understood | |
761 | that the user who changes the contents of definitions files in the | |
762 | Library will not necessarily be able to recompile the application | |
763 | to use the modified definitions.) | |
764 | ||
765 | b) Accompany the work with a written offer, valid for at | |
766 | least three years, to give the same user the materials | |
767 | specified in Subsection 6a, above, for a charge no more | |
768 | than the cost of performing this distribution. | |
769 | ||
770 | c) If distribution of the work is made by offering access to copy | |
771 | from a designated place, offer equivalent access to copy the above | |
772 | specified materials from the same place. | |
773 | ||
774 | d) Verify that the user has already received a copy of these | |
775 | materials or that you have already sent this user a copy. | |
776 | ||
777 | For an executable, the required form of the "work that uses the | |
778 | Library" must include any data and utility programs needed for | |
779 | reproducing the executable from it. However, as a special exception, | |
780 | the source code distributed need not include anything that is normally | |
781 | distributed (in either source or binary form) with the major | |
782 | components (compiler, kernel, and so on) of the operating system on | |
783 | which the executable runs, unless that component itself accompanies | |
784 | the executable. | |
785 | ||
786 | It may happen that this requirement contradicts the license | |
787 | restrictions of other proprietary libraries that do not normally | |
788 | accompany the operating system. Such a contradiction means you cannot | |
789 | use both them and the Library together in an executable that you | |
790 | distribute. | |
791 | \f | |
792 | 7. You may place library facilities that are a work based on the | |
793 | Library side-by-side in a single library together with other library | |
794 | facilities not covered by this License, and distribute such a combined | |
795 | library, provided that the separate distribution of the work based on | |
796 | the Library and of the other library facilities is otherwise | |
797 | permitted, and provided that you do these two things: | |
798 | ||
799 | a) Accompany the combined library with a copy of the same work | |
800 | based on the Library, uncombined with any other library | |
801 | facilities. This must be distributed under the terms of the | |
802 | Sections above. | |
803 | ||
804 | b) Give prominent notice with the combined library of the fact | |
805 | that part of it is a work based on the Library, and explaining | |
806 | where to find the accompanying uncombined form of the same work. | |
807 | ||
808 | 8. You may not copy, modify, sublicense, link with, or distribute | |
809 | the Library except as expressly provided under this License. Any | |
810 | attempt otherwise to copy, modify, sublicense, link with, or | |
811 | distribute the Library is void, and will automatically terminate your | |
812 | rights under this License. However, parties who have received copies, | |
813 | or rights, from you under this License will not have their licenses | |
814 | terminated so long as such parties remain in full compliance. | |
815 | ||
816 | 9. You are not required to accept this License, since you have not | |
817 | signed it. However, nothing else grants you permission to modify or | |
818 | distribute the Library or its derivative works. These actions are | |
819 | prohibited by law if you do not accept this License. Therefore, by | |
820 | modifying or distributing the Library (or any work based on the | |
821 | Library), you indicate your acceptance of this License to do so, and | |
822 | all its terms and conditions for copying, distributing or modifying | |
823 | the Library or works based on it. | |
824 | ||
825 | 10. Each time you redistribute the Library (or any work based on the | |
826 | Library), the recipient automatically receives a license from the | |
827 | original licensor to copy, distribute, link with or modify the Library | |
828 | subject to these terms and conditions. You may not impose any further | |
829 | restrictions on the recipients' exercise of the rights granted herein. | |
830 | You are not responsible for enforcing compliance by third parties to | |
831 | this License. | |
832 | \f | |
833 | 11. If, as a consequence of a court judgment or allegation of patent | |
834 | infringement or for any other reason (not limited to patent issues), | |
835 | conditions are imposed on you (whether by court order, agreement or | |
836 | otherwise) that contradict the conditions of this License, they do not | |
837 | excuse you from the conditions of this License. If you cannot | |
838 | distribute so as to satisfy simultaneously your obligations under this | |
839 | License and any other pertinent obligations, then as a consequence you | |
840 | may not distribute the Library at all. For example, if a patent | |
841 | license would not permit royalty-free redistribution of the Library by | |
842 | all those who receive copies directly or indirectly through you, then | |
843 | the only way you could satisfy both it and this License would be to | |
844 | refrain entirely from distribution of the Library. | |
845 | ||
846 | If any portion of this section is held invalid or unenforceable under any | |
847 | particular circumstance, the balance of the section is intended to apply, | |
848 | and the section as a whole is intended to apply in other circumstances. | |
849 | ||
850 | It is not the purpose of this section to induce you to infringe any | |
851 | patents or other property right claims or to contest validity of any | |
852 | such claims; this section has the sole purpose of protecting the | |
853 | integrity of the free software distribution system which is | |
854 | implemented by public license practices. Many people have made | |
855 | generous contributions to the wide range of software distributed | |
856 | through that system in reliance on consistent application of that | |
857 | system; it is up to the author/donor to decide if he or she is willing | |
858 | to distribute software through any other system and a licensee cannot | |
859 | impose that choice. | |
860 | ||
861 | This section is intended to make thoroughly clear what is believed to | |
862 | be a consequence of the rest of this License. | |
863 | ||
864 | 12. If the distribution and/or use of the Library is restricted in | |
865 | certain countries either by patents or by copyrighted interfaces, the | |
866 | original copyright holder who places the Library under this License may add | |
867 | an explicit geographical distribution limitation excluding those countries, | |
868 | so that distribution is permitted only in or among countries not thus | |
869 | excluded. In such case, this License incorporates the limitation as if | |
870 | written in the body of this License. | |
871 | ||
872 | 13. The Free Software Foundation may publish revised and/or new | |
873 | versions of the Library General Public License from time to time. | |
874 | Such new versions will be similar in spirit to the present version, | |
875 | but may differ in detail to address new problems or concerns. | |

877 | Each version is given a distinguishing version number. If the Library | |
878 | specifies a version number of this License which applies to it and | |
879 | "any later version", you have the option of following the terms and | |
880 | conditions either of that version or of any later version published by | |
881 | the Free Software Foundation. If the Library does not specify a | |
882 | license version number, you may choose any version ever published by | |
883 | the Free Software Foundation. | |
884 | \f | |
885 | 14. If you wish to incorporate parts of the Library into other free | |
886 | programs whose distribution conditions are incompatible with these, | |
887 | write to the author to ask for permission. For software which is | |
888 | copyrighted by the Free Software Foundation, write to the Free | |
889 | Software Foundation; we sometimes make exceptions for this. Our | |
890 | decision will be guided by the two goals of preserving the free status | |
891 | of all derivatives of our free software and of promoting the sharing | |
892 | and reuse of software generally. | |
893 | ||
894 | NO WARRANTY | |
895 | ||
896 | 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO | |
897 | WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. | |
898 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR | |
899 | OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY | |
900 | KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE | |
901 | IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
902 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE | |
903 | LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME | |
904 | THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
905 | ||
906 | 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN | |
907 | WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY | |
908 | AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU | |
909 | FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR | |
910 | CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE | |
911 | LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING | |
912 | RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A | |
913 | FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF | |
914 | SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH | |
915 | DAMAGES. | |

919 | Appendix: How to Apply These Terms to Your New Libraries | |
920 | ||
921 | If you develop a new library, and you want it to be of the greatest | |
922 | possible use to the public, we recommend making it free software that | |
923 | everyone can redistribute and change. You can do so by permitting | |
924 | redistribution under these terms (or, alternatively, under the terms of the | |
925 | ordinary General Public License). | |
926 | ||
927 | To apply these terms, attach the following notices to the library. It is | |
928 | safest to attach them to the start of each source file to most effectively | |
929 | convey the exclusion of warranty; and each file should have at least the | |
930 | "copyright" line and a pointer to where the full notice is found. | |
931 | ||
932 | <one line to give the library's name and a brief idea of what it does.> | |
933 | Copyright (C) <year> <name of author> | |
934 | ||
935 | This library is free software; you can redistribute it and/or | |
936 | modify it under the terms of the GNU Library General Public | |
937 | License as published by the Free Software Foundation; either | |
938 | version 2 of the License, or (at your option) any later version. | |
939 | ||
940 | This library is distributed in the hope that it will be useful, | |
941 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
942 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU | |
943 | Library General Public License for more details. | |
944 | ||
945 | You should have received a copy of the GNU Library General Public | |
946 | License along with this library; if not, write to the Free | |
947 | Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. | |
948 | ||
949 | Also add information on how to contact you by electronic and paper mail. | |
950 | ||
951 | You should also get your employer (if you work as a programmer) or your | |
952 | school, if any, to sign a "copyright disclaimer" for the library, if | |
953 | necessary. Here is a sample; alter the names: | |
954 | ||
955 | Yoyodyne, Inc., hereby disclaims all copyright interest in the | |
956 | library `Frob' (a library for tweaking knobs) written by James Random Hacker. | |
