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

451 convey the exclusion of warranty; and each file should have at least the | |
452 "copyright" line and a pointer to where the full notice is found. | |
