2 | GNU LIBRARY GENERAL PUBLIC LICENSE | |
3 | ================================== | |
4 | Version 2, June 1991 | |
5 | ||
6 | Copyright (C) 1991 Free Software Foundation, Inc. | |
7 | 675 Mass Ave, Cambridge, MA 02139, USA | |
8 | Everyone is permitted to copy and distribute verbatim copies | |
9 | of this license document, but changing it is not allowed. | |
10 | ||
11 | [This is the first released version of the library GPL. It is | |
12 | numbered 2 because it goes with version 2 of the ordinary GPL.] | |
13 | ||
14 | Preamble | |
15 | ||
16 | The licenses for most software are designed to take away your | |
17 | freedom to share and change it. By contrast, the GNU General | |
18 | Public Licenses are intended to guarantee your freedom to share | |
19 | and change free software--to make sure the software is free for | |
20 | all its users. | |
21 | ||
22 | This license, the Library General Public License, applies to | |
23 | some specially designated Free Software Foundation software, and | |
24 | to any other libraries whose authors decide to use it. You can | |
25 | use it for your libraries, too. | |
26 | ||
27 | When we speak of free software, we are referring to freedom, not | |
28 | price. Our General Public Licenses are designed to make sure | |
29 | that you have the freedom to distribute copies of free software | |
30 | (and charge for this service if you wish), that you receive | |
31 | source code or can get it if you want it, that you can change | |
32 | the software or use pieces of it in new free programs; and that | |
33 | you know you can do these things. | |
34 | ||
35 | To protect your rights, we need to make restrictions that forbid | |
36 | anyone to deny you these rights or to ask you to surrender the | |
37 | rights. These restrictions translate to certain responsibilities | |
38 | for you if you distribute copies of the library, or if you | |
39 | modify it. | |
40 | ||
41 | For example, if you distribute copies of the library, whether | |
42 | gratis or for a fee, you must give the recipients all the rights | |
43 | that we gave you. You must make sure that they, too, receive or | |
44 | can get the source code. If you link a program with the | |
45 | library, you must provide complete object files to the | |
46 | recipients so that they can relink them with the library, after | |
47 | making changes to the library and recompiling it. And you must | |
48 | show them these terms so they know their rights. | |
49 | ||
50 | Our method of protecting your rights has two steps: (1) | |
51 | copyright the library, and (2) offer you this license which | |
52 | gives you legal permission to copy, distribute and/or modify the | |
53 | library. | |
54 | ||
55 | Also, for each distributor's protection, we want to make certain | |
56 | that everyone understands that there is no warranty for this | |
57 | free library. If the library is modified by someone else and | |
58 | passed on, we want its recipients to know that what they have is | |
59 | not the original version, so that any problems introduced by | |
60 | others will not reflect on the original authors' reputations. | |
61 | ||
62 | Finally, any free program is threatened constantly by software | |
63 | patents. We wish to avoid the danger that companies | |
64 | distributing free software will individually obtain patent | |
65 | licenses, thus in effect transforming the program into | |
66 | proprietary software. To prevent this, we have made it clear | |
67 | that any patent must be licensed for everyone's free use or not | |
68 | licensed at all. | |
69 | ||
70 | Most GNU software, including some libraries, is covered by the | |
71 | ordinary GNU General Public License, which was designed for | |
72 | utility programs. This license, the GNU Library General Public | |
73 | License, applies to certain designated libraries. This license | |
74 | is quite different from the ordinary one; be sure to read it in | |
75 | full, and don't assume that anything in it is the same as in the | |
76 | ordinary license. | |
77 | ||
78 | The reason we have a separate public license for some libraries | |
79 | is that they blur the distinction we usually make between | |
80 | modifying or adding to a program and simply using it. Linking a | |
81 | program with a library, without changing the library, is in some | |
82 | sense simply using the library, and is analogous to running a | |
83 | utility program or application program. However, in a textual | |
84 | and legal sense, the linked executable is a combined work, a | |
85 | derivative of the original library, and the ordinary General | |
86 | Public License treats it as such. | |
87 | ||
88 | Because of this blurred distinction, using the ordinary General | |
89 | Public License for libraries did not effectively promote | |
90 | software sharing, because most developers did not use the | |
91 | libraries. We concluded that weaker conditions might promote | |
92 | sharing better. | |
93 | ||
94 | However, unrestricted linking of non-free programs would deprive | |
95 | the users of those programs of all benefit from the free status | |
96 | of the libraries themselves. This Library General Public | |
97 | License is intended to permit developers of non-free programs to | |
98 | use free libraries, while preserving your freedom as a user of | |
99 | such programs to change the free libraries that are incorporated | |
100 | in them. (We have not seen how to achieve this as regards | |
101 | changes in header files, but we have achieved it as regards | |
102 | changes in the actual functions of the Library.) The hope is | |
103 | that this will lead to faster development of free libraries. | |
104 | ||
105 | The precise terms and conditions for copying, distribution and | |
106 | modification follow. Pay close attention to the difference | |
107 | between a "work based on the library" and a "work that uses the | |
108 | library". The former contains code derived from the library, | |
109 | while the latter only works together with the library. | |
110 | ||
111 | Note that it is possible for a library to be covered by the | |
112 | ordinary General Public License rather than by this special one. | |
113 | ||
114 | GNU LIBRARY GENERAL PUBLIC LICENSE | |
115 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
116 | ||
117 | 0. This License Agreement applies to any software library which | |
118 | contains a notice placed by the copyright holder or other | |
119 | authorized party saying it may be distributed under the terms of | |
120 | this Library General Public License (also called "this | |
121 | License"). Each licensee is addressed as "you". | |
122 | ||
123 | A "library" means a collection of software functions and/or data | |
124 | prepared so as to be conveniently linked with application | |
125 | programs (which use some of those functions and data) to form | |
126 | executables. | |
127 | ||
128 | The "Library", below, refers to any such software library or | |
129 | work which has been distributed under these terms. A "work | |
130 | based on the Library" means either the Library or any derivative | |
131 | work under copyright law: that is to say, a work containing the | |
132 | Library or a portion of it, either verbatim or with | |
133 | modifications and/or translated straightforwardly into another | |
134 | language. (Hereinafter, translation is included without | |
135 | limitation in the term "modification".) | |
136 | ||
137 | "Source code" for a work means the preferred form of the work | |
138 | for making modifications to it. For a library, complete source | |
139 | code means all the source code for all modules it contains, plus | |
140 | any associated interface definition files, plus the scripts used | |
141 | to control compilation and installation of the library. | |
142 | ||
143 | Activities other than copying, distribution and modification are | |
144 | not covered by this License; they are outside its scope. The | |
145 | act of running a program using the Library is not restricted, | |
146 | and output from such a program is covered only if its contents | |
147 | constitute a work based on the Library (independent of the use | |
148 | of the Library in a tool for writing it). Whether that is true | |
149 | depends on what the Library does and what the program that uses | |
150 | the Library does. | |
151 | ||
152 | 1. You may copy and distribute verbatim copies of the Library's | |
153 | complete source code as you receive it, in any medium, provided | |
154 | that you conspicuously and appropriately publish on each copy an | |
155 | appropriate copyright notice and disclaimer of warranty; keep | |
156 | intact all the notices that refer to this License and to the | |
157 | absence of any warranty; and distribute a copy of this License | |
158 | along with the Library. | |
159 | ||
160 | You may charge a fee for the physical act of transferring a | |
161 | copy, and you may at your option offer warranty protection in | |
162 | exchange for a fee. | |
163 | ||
164 | 2. You may modify your copy or copies of the Library or any | |
165 | portion of it, thus forming a work based on the Library, and | |
166 | copy and distribute such modifications or work under the terms | |
167 | of Section 1 above, provided that you also meet all of these | |
168 | conditions: | |
169 | ||
170 | a) The modified work must itself be a software library. | |
171 | ||
172 | b) You must cause the files modified to carry prominent notices | |
173 | stating that you changed the files and the date of any change. | |
174 | ||
175 | c) You must cause the whole of the work to be licensed at no | |
176 | charge to all third parties under the terms of this License. | |
177 | ||
178 | d) If a facility in the modified Library refers to a function or a | |
179 | table of data to be supplied by an application program that uses | |
180 | the facility, other than as an argument passed when the facility | |
181 | is invoked, then you must make a good faith effort to ensure that, | |
182 | in the event an application does not supply such function or | |
183 | table, the facility still operates, and performs whatever part of | |
184 | its purpose remains meaningful. | |
185 | ||
186 | (For example, a function in a library to compute square roots has | |
187 | a purpose that is entirely well-defined independent of the | |
188 | application. Therefore, Subsection 2d requires that any | |
189 | application-supplied function or table used by this function must | |
190 | be optional: if the application does not supply it, the square | |
191 | root function must still compute square roots.) | |
192 | ||
193 | These requirements apply to the modified work as a whole. If | |
194 | identifiable sections of that work are not derived from the | |
195 | Library, and can be reasonably considered independent and | |
196 | separate works in themselves, then this License, and its terms, | |
197 | do not apply to those sections when you distribute them as | |
198 | separate works. But when you distribute the same sections as | |
199 | part of a whole which is a work based on the Library, the | |
200 | distribution of the whole must be on the terms of this License, | |
201 | whose permissions for other licensees extend to the entire | |
202 | whole, and thus to each and every part regardless of who wrote | |
203 | it. | |
204 | ||
205 | Thus, it is not the intent of this section to claim rights or | |
206 | contest your rights to work written entirely by you; rather, the | |
207 | intent is to exercise the right to control the distribution of | |
208 | derivative or collective works based on the Library. | |
209 | ||
210 | In addition, mere aggregation of another work not based on the | |
211 | Library with the Library (or with a work based on the Library) | |
212 | on a volume of a storage or distribution medium does not bring | |
213 | the other work under the scope of this License. | |
214 | ||
215 | 3. You may opt to apply the terms of the ordinary GNU General | |
216 | Public License instead of this License to a given copy of the | |
217 | Library. To do this, you must alter all the notices that refer | |
218 | to this License, so that they refer to the ordinary GNU General | |
219 | Public License, version 2, instead of to this License. (If a | |
220 | newer version than version 2 of the ordinary GNU General Public | |
221 | License has appeared, then you can specify that version instead | |
222 | if you wish.) Do not make any other change in these notices. | |
223 | ||
224 | Once this change is made in a given copy, it is irreversible for | |
225 | that copy, so the ordinary GNU General Public License applies to | |
226 | all subsequent copies and derivative works made from that copy. | |
227 | ||
228 | This option is useful when you wish to copy part of the code of | |
229 | the Library into a program that is not a library. | |
230 | ||
231 | 4. You may copy and distribute the Library (or a portion or | |
232 | derivative of it, under Section 2) in object code or executable | |
233 | form under the terms of Sections 1 and 2 above provided that you | |
234 | accompany it with the complete corresponding machine-readable | |
235 | source code, which must be distributed under the terms of | |
236 | Sections 1 and 2 above on a medium customarily used for software | |
237 | interchange. | |
238 | ||
239 | If distribution of object code is made by offering access to | |
240 | copy from a designated place, then offering equivalent access to | |
241 | copy the source code from the same place satisfies the | |
242 | requirement to distribute the source code, even though third | |
243 | parties are not compelled to copy the source along with the | |
244 | object code. | |
245 | ||
246 | 5. A program that contains no derivative of any portion of the | |
247 | Library, but is designed to work with the Library by being | |
248 | compiled or linked with it, is called a "work that uses the | |
249 | Library". Such a work, in isolation, is not a derivative work | |
250 | of the Library, and therefore falls outside the scope of this | |
251 | License. | |
252 | ||
253 | However, linking a "work that uses the Library" with the Library | |
254 | creates an executable that is a derivative of the Library | |
255 | (because it contains portions of the Library), rather than a | |
256 | "work that uses the library". The executable is therefore | |
257 | covered by this License. Section 6 states terms for distribution | |
258 | of such executables. | |
259 | ||
260 | When a "work that uses the Library" uses material from a header | |
261 | file that is part of the Library, the object code for the work | |
262 | may be a derivative work of the Library even though the source | |
263 | code is not. Whether this is true is especially significant if | |
264 | the work can be linked without the Library, or if the work is | |
265 | itself a library. The threshold for this to be true is not | |
266 | precisely defined by law. | |
267 | ||
268 | If such an object file uses only numerical parameters, data | |
269 | structure layouts and accessors, and small macros and small | |
270 | inline functions (ten lines or less in length), then the use of | |
271 | the object file is unrestricted, regardless of whether it is | |
272 | legally a derivative work. (Executables containing this object | |
273 | code plus portions of the Library will still fall under Section | |
274 | 6.) | |
275 | ||
276 | Otherwise, if the work is a derivative of the Library, you may | |
277 | distribute the object code for the work under the terms of | |
278 | Section 6. Any executables containing that work also fall under | |
279 | Section 6, whether or not they are linked directly with the | |
280 | Library itself. | |
281 | ||
282 | 6. As an exception to the Sections above, you may also compile | |
283 | or link a "work that uses the Library" with the Library to | |
284 | produce a work containing portions of the Library, and | |
285 | distribute that work under terms of your choice, provided that | |
286 | the terms permit modification of the work for the customer's own | |
287 | use and reverse engineering for debugging such modifications. | |
288 | ||
289 | You must give prominent notice with each copy of the work that | |
290 | the Library is used in it and that the Library and its use are | |
291 | covered by this License. You must supply a copy of this | |
292 | License. If the work during execution displays copyright | |
293 | notices, you must include the copyright notice for the Library | |
294 | among them, as well as a reference directing the user to the | |
295 | copy of this License. Also, you must do one of these things: | |
296 | ||
297 | a) Accompany the work with the complete corresponding | |
298 | machine-readable source code for the Library including whatever | |
299 | changes were used in the work (which must be distributed under | |
300 | Sections 1 and 2 above); and, if the work is an executable linked | |
301 | with the Library, with the complete machine-readable "work that | |
302 | uses the Library", as object code and/or source code, so that the | |
303 | user can modify the Library and then relink to produce a modified | |
304 | executable containing the modified Library. (It is understood | |
305 | that the user who changes the contents of definitions files in the | |
306 | Library will not necessarily be able to recompile the application | |
307 | to use the modified definitions.) | |
308 | ||
309 | b) Accompany the work with a written offer, valid for at | |
310 | least three years, to give the same user the materials | |
311 | specified in Subsection 6a, above, for a charge no more | |
312 | than the cost of performing this distribution. | |
313 | ||
314 | c) If distribution of the work is made by offering access to copy | |
315 | from a designated place, offer equivalent access to copy the above | |
316 | specified materials from the same place. | |
317 | ||
318 | d) Verify that the user has already received a copy of these | |
319 | materials or that you have already sent this user a copy. | |
320 | ||
321 | For an executable, the required form of the "work that uses the | |
322 | Library" must include any data and utility programs needed for | |
323 | reproducing the executable from it. However, as a special | |
324 | exception, the source code distributed need not include anything | |
325 | that is normally distributed (in either source or binary form) | |
326 | with the major components (compiler, kernel, and so on) of the | |
327 | operating system on which the executable runs, unless that | |
328 | component itself accompanies the executable. | |
329 | ||
330 | It may happen that this requirement contradicts the license | |
331 | restrictions of other proprietary libraries that do not normally | |
332 | accompany the operating system. Such a contradiction means you | |
333 | cannot use both them and the Library together in an executable | |
334 | that you distribute. | |
335 | ||
336 | 7. You may place library facilities that are a work based on the | |
337 | Library side-by-side in a single library together with other | |
338 | library facilities not covered by this License, and distribute | |
339 | such a combined library, provided that the separate distribution | |
340 | of the work based on the Library and of the other library | |
341 | facilities is otherwise permitted, and provided that you do | |
342 | these two things: | |
343 | ||
344 | a) Accompany the combined library with a copy of the same work | |
345 | based on the Library, uncombined with any other library | |
346 | facilities. This must be distributed under the terms of the | |
347 | Sections above. | |
348 | ||
349 | b) Give prominent notice with the combined library of the fact | |
350 | that part of it is a work based on the Library, and explaining | |
351 | where to find the accompanying uncombined form of the same work. | |
352 | ||
353 | 8. You may not copy, modify, sublicense, link with, or | |
354 | distribute the Library except as expressly provided under this | |
355 | License. Any attempt otherwise to copy, modify, sublicense, | |
356 | link with, or distribute the Library is void, and will | |
357 | automatically terminate your rights under this License. | |
358 | However, parties who have received copies, or rights, from you | |
359 | under this License will not have their licenses terminated so | |
360 | long as such parties remain in full compliance. | |
361 | ||
362 | 9. You are not required to accept this License, since you have | |
363 | not signed it. However, nothing else grants you permission to | |
364 | modify or distribute the Library or its derivative works. These | |
365 | actions are prohibited by law if you do not accept this | |
366 | License. Therefore, by modifying or distributing the Library | |
367 | (or any work based on the Library), you indicate your acceptance | |
368 | of this License to do so, and all its terms and conditions for | |
369 | copying, distributing or modifying the Library or works based on | |
370 | it. | |
371 | ||
372 | 10. Each time you redistribute the Library (or any work based on | |
373 | the Library), the recipient automatically receives a license | |
374 | from the original licensor to copy, distribute, link with or | |
375 | modify the Library subject to these terms and conditions. You | |
376 | may not impose any further restrictions on the recipients' | |
377 | exercise of the rights granted herein. You are not responsible | |
378 | for enforcing compliance by third parties to this License. | |
379 | ||
380 | 11. If, as a consequence of a court judgment or allegation of | |
381 | patent infringement or for any other reason (not limited to | |
382 | patent issues), conditions are imposed on you (whether by court | |
383 | order, agreement or otherwise) that contradict the conditions of | |
384 | this License, they do not excuse you from the conditions of this | |
385 | License. If you cannot distribute so as to satisfy | |
386 | simultaneously your obligations under this License and any other | |
387 | pertinent obligations, then as a consequence you may not | |
388 | distribute the Library at all. For example, if a patent license | |
389 | would not permit royalty-free redistribution of the Library by | |
390 | all those who receive copies directly or indirectly through you, | |
391 | then the only way you could satisfy both it and this License | |
392 | would be to refrain entirely from distribution of the Library. | |
393 | ||
394 | If any portion of this section is held invalid or unenforceable | |
395 | under any particular circumstance, the balance of the section is | |
396 | intended to apply, and the section as a whole is intended to | |
397 | apply in other circumstances. | |
398 | ||
399 | It is not the purpose of this section to induce you to infringe | |
400 | any patents or other property right claims or to contest | |
401 | validity of any such claims; this section has the sole purpose | |
402 | of protecting the integrity of the free software distribution | |
403 | system which is implemented by public license practices. Many | |
404 | people have made generous contributions to the wide range of | |
405 | software distributed through that system in reliance on | |
406 | consistent application of that system; it is up to the | |
407 | author/donor to decide if he or she is willing to distribute | |
408 | software through any other system and a licensee cannot impose | |
409 | that choice. | |
410 | ||
411 | This section is intended to make thoroughly clear what is | |
412 | believed to be a consequence of the rest of this License. | |
413 | ||
414 | 12. If the distribution and/or use of the Library is restricted | |
415 | in certain countries either by patents or by copyrighted | |
416 | interfaces, the original copyright holder who places the Library | |
417 | under this License may add an explicit geographical distribution | |
418 | limitation excluding those countries, so that distribution is | |
419 | permitted only in or among countries not thus excluded. In such | |
420 | case, this License incorporates the limitation as if written in | |
421 | the body of this License. | |
422 | ||
423 | 13. The Free Software Foundation may publish revised and/or new | |
424 | versions of the Library General Public License from time to | |
425 | time. Such new versions will be similar in spirit to the present | |
426 | version, but may differ in detail to address new problems or | |
427 | concerns. | |
428 | ||
429 | Each version is given a distinguishing version number. If the | |
430 | Library specifies a version number of this License which applies | |
431 | to it and "any later version", you have the option of following | |
432 | the terms and conditions either of that version or of any later | |
433 | version published by the Free Software Foundation. If the | |
434 | Library does not specify a license version number, you may | |
435 | choose any version ever published by the Free Software | |
436 | Foundation. | |
437 | ||
438 | 14. If you wish to incorporate parts of the Library into other | |
439 | free programs whose distribution conditions are incompatible | |
440 | with these, write to the author to ask for permission. For | |
441 | software which is copyrighted by the Free Software Foundation, | |
442 | write to the Free Software Foundation; we sometimes make | |
443 | exceptions for this. Our decision will be guided by the two | |
444 | goals of preserving the free status of all derivatives of our | |
445 | free software and of promoting the sharing and reuse of software | |
446 | generally. | |
447 | ||
448 | NO WARRANTY | |
449 | ||
450 | 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO | |
451 | WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. | |
452 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR | |

472 | Appendix: How to Apply These Terms to Your New Libraries | |
473 | ||
474 | If you develop a new library, and you want it to be of the | |
475 | greatest possible use to the public, we recommend making it free | |
476 | software that everyone can redistribute and change. You can do | |
477 | so by permitting redistribution under these terms (or, | |
478 | alternatively, under the terms of the ordinary General Public | |
479 | License). | |
480 | ||
481 | To apply these terms, attach the following notices to the | |
482 | library. It is safest to attach them to the start of each | |
483 | source file to most effectively convey the exclusion of | |
484 | warranty; and each file should have at least the "copyright" | |
485 | line and a pointer to where the full notice is found. | |
486 | ||
487 | <one line to give the library's name and a brief idea of what it does.> | |
488 | Copyright (C) <year> <name of author> | |
489 | ||
490 | This library is free software; you can redistribute it and/or | |
491 | modify it under the terms of the GNU Library General Public | |
492 | License as published by the Free Software Foundation; either | |
493 | version 2 of the License, or (at your option) any later version. | |
494 | ||
495 | This library is distributed in the hope that it will be useful, | |
496 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
497 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU | |
498 | Library General Public License for more details. | |
499 | ||
500 | You should have received a copy of the GNU Library General Public | |
501 | License along with this library; if not, write to the Free | |
502 | Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. | |
503 | ||
504 | Also add information on how to contact you by electronic and paper mail. | |
505 | ||
506 | You should also get your employer (if you work as a programmer) or your | |
507 | school, if any, to sign a "copyright disclaimer" for the library, if | |
508 | necessary. Here is a sample; alter the names: | |
509 | ||
510 | Yoyodyne, Inc., hereby disclaims all copyright interest in the | |
511 | library `Frob' (a library for tweaking knobs) written by James Random Hacker. | |
