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

399 | How to Apply These Terms to Your New Libraries | ||||
400 | | ||||
401 | If you develop a new library, and you want it to be of the greatest possible | ||||
402 | use to the public, we recommend making it free software that everyone can | ||||
403 | redistribute and change. You can do so by permitting redistribution under | ||||
404 | these terms (or, alternatively, under the terms of the ordinary General Public | ||||
405 | License). | ||||
406 | | ||||
407 | To apply these terms, attach the following notices to the library. It is safest | ||||
408 | to attach them to the start of each source file to most effectively convey | ||||
409 | the exclusion of warranty; and each file should have at least the "copyright" | ||||
410 | line and a pointer to where the full notice is found. | ||||
411 | | ||||
412 | one line to give the library's name and an idea of what it does. | ||||
413 | | ||||
414 | Copyright (C) year name of author | ||||

421 | This library is distributed in the hope that it will be useful, but WITHOUT | ||||
422 | ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS | ||||

424 | details. | ||||
425 | | ||||
426 | You should have received a copy of the GNU Library General Public License | ||||
427 | along with this library; if not, write to the Free Software Foundation, Inc., | ||||
428 | 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA. | ||||
429 | | ||||
430 | Also add information on how to contact you by electronic and paper mail. | ||||
431 | | ||||
432 | You should also get your employer (if you work as a programmer) or your school, | ||||
433 | if any, to sign a "copyright disclaimer" for the library, if necessary. Here | ||||
434 | is a sample; alter the names: | ||||
