24 | @unnumberedsec Preamble | |
25 | ||
26 | The licenses for most software are designed to take away your | |
27 | freedom to share and change it. By contrast, the GNU General Public | |
28 | Licenses are intended to guarantee your freedom to share and change | |
29 | free software---to make sure the software is free for all its users. | |
30 | ||
31 | This license, the Library General Public License, applies to some | |
32 | specially designated Free Software Foundation software, and to any | |
33 | other libraries whose authors decide to use it. You can use it for | |
34 | your libraries, too. | |
35 | ||
36 | When we speak of free software, we are referring to freedom, not | |
37 | price. Our General Public Licenses are designed to make sure that you | |
38 | have the freedom to distribute copies of free software (and charge for | |
39 | this service if you wish), that you receive source code or can get it | |
40 | if you want it, that you can change the software or use pieces of it | |
41 | in new free programs; and that you know you can do these things. | |
42 | ||
43 | To protect your rights, we need to make restrictions that forbid | |
44 | anyone to deny you these rights or to ask you to surrender the rights. | |
45 | These restrictions translate to certain responsibilities for you if | |
46 | you distribute copies of the library, or if you modify it. | |
47 | ||
48 | For example, if you distribute copies of the library, whether gratis | |
49 | or for a fee, you must give the recipients all the rights that we gave | |
50 | you. You must make sure that they, too, receive or can get the source | |
51 | code. If you link a program with the library, you must provide | |
52 | complete object files to the recipients so that they can relink them | |
53 | with the library, after making changes to the library and recompiling | |
54 | it. And you must show them these terms so they know their rights. | |
55 | ||
56 | Our method of protecting your rights has two steps: (1) copyright | |
57 | the library, and (2) offer you this license which gives you legal | |
58 | permission to copy, distribute and/or modify the library. | |
59 | ||
60 | Also, for each distributor's protection, we want to make certain | |
61 | that everyone understands that there is no warranty for this free | |
62 | library. If the library is modified by someone else and passed on, we | |
63 | want its recipients to know that what they have is not the original | |
64 | version, so that any problems introduced by others will not reflect on | |
65 | the original authors' reputations. | |
66 | ||
67 | Finally, any free program is threatened constantly by software | |
68 | patents. We wish to avoid the danger that companies distributing free | |
69 | software will individually obtain patent licenses, thus in effect | |
70 | transforming the program into proprietary software. To prevent this, | |
71 | we have made it clear that any patent must be licensed for everyone's | |
72 | free use or not licensed at all. | |
73 | ||
74 | Most GNU software, including some libraries, is covered by the ordinary | |
75 | GNU General Public License, which was designed for utility programs. This | |
76 | license, the GNU Library General Public License, applies to certain | |
77 | designated libraries. This license is quite different from the ordinary | |
78 | one; be sure to read it in full, and don't assume that anything in it is | |
79 | the same as in the ordinary license. | |
80 | ||
81 | The reason we have a separate public license for some libraries is that | |
82 | they blur the distinction we usually make between modifying or adding to a | |
83 | program and simply using it. Linking a program with a library, without | |
84 | changing the library, is in some sense simply using the library, and is | |
85 | analogous to running a utility program or application program. However, in | |
86 | a textual and legal sense, the linked executable is a combined work, a | |
87 | derivative of the original library, and the ordinary General Public License | |
88 | treats it as such. | |
89 | ||
90 | Because of this blurred distinction, using the ordinary General | |
91 | Public License for libraries did not effectively promote software | |
92 | sharing, because most developers did not use the libraries. We | |
93 | concluded that weaker conditions might promote sharing better. | |
94 | ||
95 | However, unrestricted linking of non-free programs would deprive the | |
96 | users of those programs of all benefit from the free status of the | |
97 | libraries themselves. This Library General Public License is intended to | |
98 | permit developers of non-free programs to use free libraries, while | |
99 | preserving your freedom as a user of such programs to change the free | |
100 | libraries that are incorporated in them. (We have not seen how to achieve | |
101 | this as regards changes in header files, but we have achieved it as regards | |
102 | changes in the actual functions of the Library.) The hope is that this | |
103 | 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 between a | |
107 | ``work based on the library'' and a ``work that uses the library''. The | |
108 | former contains code derived from the library, while the latter only | |
109 | works together with the library. | |
110 | ||
111 | Note that it is possible for a library to be covered by the ordinary | |
112 | General Public License rather than by this special one. | |

122 | @item | |
123 | This License Agreement applies to any software library which | |
124 | contains a notice placed by the copyright holder or other authorized | |
125 | party saying it may be distributed under the terms of this Library | |
126 | General Public License (also called ``this License''). Each licensee is | |
127 | addressed as ``you''. | |
128 | ||
129 | A ``library'' means a collection of software functions and/or data | |
130 | prepared so as to be conveniently linked with application programs | |
131 | (which use some of those functions and data) to form executables. | |
132 | ||
133 | The ``Library'', below, refers to any such software library or work | |
134 | which has been distributed under these terms. A ``work based on the | |
135 | Library'' means either the Library or any derivative work under | |
136 | copyright law: that is to say, a work containing the Library or a | |
137 | portion of it, either verbatim or with modifications and/or translated | |
138 | straightforwardly into another language. (Hereinafter, translation is | |
139 | included without limitation in the term ``modification''.) | |
140 | ||
141 | ``Source code'' for a work means the preferred form of the work for | |
142 | making modifications to it. For a library, complete source code means | |
143 | all the source code for all modules it contains, plus any associated | |
144 | interface definition files, plus the scripts used to control compilation | |
145 | and installation of the library. | |
146 | ||
147 | Activities other than copying, distribution and modification are not | |
148 | covered by this License; they are outside its scope. The act of | |
149 | running a program using the Library is not restricted, and output from | |
150 | such a program is covered only if its contents constitute a work based | |
151 | on the Library (independent of the use of the Library in a tool for | |
152 | writing it). Whether that is true depends on what the Library does | |
153 | and what the program that uses the Library does. | |
154 | ||
155 | @item | |
156 | You may copy and distribute verbatim copies of the Library's | |
157 | complete source code as you receive it, in any medium, provided that | |
158 | you conspicuously and appropriately publish on each copy an | |
159 | appropriate copyright notice and disclaimer of warranty; keep intact | |
160 | all the notices that refer to this License and to the absence of any | |
161 | warranty; and distribute a copy of this License along with the | |
162 | Library. | |
163 | ||
164 | You may charge a fee for the physical act of transferring a copy, | |
165 | and you may at your option offer warranty protection in exchange for a | |
166 | fee. | |
167 | ||
168 | @item | |
169 | You may modify your copy or copies of the Library or any portion | |
170 | of it, thus forming a work based on the Library, and copy and | |
171 | distribute such modifications or work under the terms of Section 1 | |
172 | above, provided that you also meet all of these conditions: | |
173 | ||
174 | @enumerate a | |
175 | @item | |
176 | The modified work must itself be a software library. | |
177 | ||
178 | @item | |
179 | You must cause the files modified to carry prominent notices | |
180 | stating that you changed the files and the date of any change. | |
181 | ||
182 | @item | |
183 | You must cause the whole of the work to be licensed at no | |
184 | charge to all third parties under the terms of this License. | |
185 | ||
186 | @item | |
187 | If a facility in the modified Library refers to a function or a | |
188 | table of data to be supplied by an application program that uses | |
189 | the facility, other than as an argument passed when the facility | |
190 | is invoked, then you must make a good faith effort to ensure that, | |
191 | in the event an application does not supply such function or | |
192 | table, the facility still operates, and performs whatever part of | |
193 | its purpose remains meaningful. | |
194 | ||
195 | (For example, a function in a library to compute square roots has | |
196 | a purpose that is entirely well-defined independent of the | |
197 | application. Therefore, Subsection 2d requires that any | |
198 | application-supplied function or table used by this function must | |
199 | be optional: if the application does not supply it, the square | |
200 | root function must still compute square roots.) | |
201 | @end enumerate | |
202 | ||
203 | These requirements apply to the modified work as a whole. If | |
204 | identifiable sections of that work are not derived from the Library, | |
205 | and can be reasonably considered independent and separate works in | |
206 | themselves, then this License, and its terms, do not apply to those | |
207 | sections when you distribute them as separate works. But when you | |
208 | distribute the same sections as part of a whole which is a work based | |
209 | on the Library, the distribution of the whole must be on the terms of | |
210 | this License, whose permissions for other licensees extend to the | |
211 | entire whole, and thus to each and every part regardless of who wrote | |
212 | it. | |
213 | ||
214 | Thus, it is not the intent of this section to claim rights or contest | |
215 | your rights to work written entirely by you; rather, the intent is to | |
216 | exercise the right to control the distribution of derivative or | |
217 | collective works based on the Library. | |
218 | ||
219 | In addition, mere aggregation of another work not based on the Library | |
220 | with the Library (or with a work based on the Library) on a volume of | |
221 | a storage or distribution medium does not bring the other work under | |
222 | the scope of this License. | |
223 | ||
224 | @item | |
225 | You may opt to apply the terms of the ordinary GNU General Public | |
226 | License instead of this License to a given copy of the Library. To do | |
227 | this, you must alter all the notices that refer to this License, so | |
228 | that they refer to the ordinary GNU General Public License, version 2, | |
229 | instead of to this License. (If a newer version than version 2 of the | |
230 | ordinary GNU General Public License has appeared, then you can specify | |
231 | that version instead if you wish.) Do not make any other change in | |
232 | these notices. | |
233 | ||
234 | Once this change is made in a given copy, it is irreversible for | |
235 | that copy, so the ordinary GNU General Public License applies to all | |
236 | subsequent copies and derivative works made from that copy. | |
237 | ||
238 | This option is useful when you wish to copy part of the code of | |
239 | the Library into a program that is not a library. | |
240 | ||
241 | @item | |
242 | You may copy and distribute the Library (or a portion or | |
243 | derivative of it, under Section 2) in object code or executable form | |
244 | under the terms of Sections 1 and 2 above provided that you accompany | |
245 | it with the complete corresponding machine-readable source code, which | |
246 | must be distributed under the terms of Sections 1 and 2 above on a | |
247 | medium customarily used for software interchange. | |
248 | ||
249 | If distribution of object code is made by offering access to copy | |
250 | from a designated place, then offering equivalent access to copy the | |
251 | source code from the same place satisfies the requirement to | |
252 | distribute the source code, even though third parties are not | |
253 | compelled to copy the source along with the object code. | |
254 | ||
255 | @item | |
256 | A program that contains no derivative of any portion of the | |
257 | Library, but is designed to work with the Library by being compiled or | |
258 | linked with it, is called a ``work that uses the Library''. Such a | |
259 | work, in isolation, is not a derivative work of the Library, and | |
260 | therefore falls outside the scope of this License. | |
261 | ||
262 | However, linking a ``work that uses the Library'' with the Library | |
263 | creates an executable that is a derivative of the Library (because it | |
264 | contains portions of the Library), rather than a ``work that uses the | |
265 | library''. The executable is therefore covered by this License. | |
266 | Section 6 states terms for distribution of such executables. | |
267 | ||
268 | When a ``work that uses the Library'' uses material from a header file | |
269 | that is part of the Library, the object code for the work may be a | |
270 | derivative work of the Library even though the source code is not. | |
271 | Whether this is true is especially significant if the work can be | |
272 | linked without the Library, or if the work is itself a library. The | |
273 | threshold for this to be true is not precisely defined by law. | |
274 | ||
275 | If such an object file uses only numerical parameters, data | |
276 | structure layouts and accessors, and small macros and small inline | |
277 | functions (ten lines or less in length), then the use of the object | |
278 | file is unrestricted, regardless of whether it is legally a derivative | |
279 | work. (Executables containing this object code plus portions of the | |
280 | Library will still fall under Section 6.) | |
281 | ||
282 | Otherwise, if the work is a derivative of the Library, you may | |
283 | distribute the object code for the work under the terms of Section 6. | |
284 | Any executables containing that work also fall under Section 6, | |
285 | whether or not they are linked directly with the Library itself. | |
286 | ||
287 | @item | |
288 | As an exception to the Sections above, you may also compile or | |
289 | link a ``work that uses the Library'' with the Library to produce a | |
290 | work containing portions of the Library, and distribute that work | |
291 | under terms of your choice, provided that the terms permit | |
292 | modification of the work for the customer's own use and reverse | |
293 | engineering for debugging such modifications. | |
294 | ||
295 | You must give prominent notice with each copy of the work that the | |
296 | Library is used in it and that the Library and its use are covered by | |
297 | this License. You must supply a copy of this License. If the work | |
298 | during execution displays copyright notices, you must include the | |
299 | copyright notice for the Library among them, as well as a reference | |
300 | directing the user to the copy of this License. Also, you must do one | |
301 | of these things: | |
302 | ||
303 | @enumerate a | |
304 | @item | |
305 | Accompany the work with the complete corresponding | |
306 | machine-readable source code for the Library including whatever | |
307 | changes were used in the work (which must be distributed under | |
308 | Sections 1 and 2 above); and, if the work is an executable linked | |
309 | with the Library, with the complete machine-readable ``work that | |
310 | uses the Library'', as object code and/or source code, so that the | |
311 | user can modify the Library and then relink to produce a modified | |
312 | executable containing the modified Library. (It is understood | |
313 | that the user who changes the contents of definitions files in the | |
314 | Library will not necessarily be able to recompile the application | |
315 | to use the modified definitions.) | |
316 | ||
317 | @item | |
318 | Accompany the work with a written offer, valid for at | |
319 | least three years, to give the same user the materials | |
320 | specified in Subsection 6a, above, for a charge no more | |
321 | than the cost of performing this distribution. | |
322 | ||
323 | @item | |
324 | If distribution of the work is made by offering access to copy | |
325 | from a designated place, offer equivalent access to copy the above | |
326 | specified materials from the same place. | |
327 | ||
328 | @item | |
329 | Verify that the user has already received a copy of these | |
330 | materials or that you have already sent this user a copy. | |
331 | @end enumerate | |
332 | ||
333 | For an executable, the required form of the ``work that uses the | |
334 | Library'' must include any data and utility programs needed for | |
335 | reproducing the executable from it. However, as a special exception, | |
336 | the source code distributed need not include anything that is normally | |
337 | distributed (in either source or binary form) with the major | |
338 | components (compiler, kernel, and so on) of the operating system on | |
339 | which the executable runs, unless that component itself accompanies | |
340 | the executable. | |
341 | ||
342 | It may happen that this requirement contradicts the license | |
343 | restrictions of other proprietary libraries that do not normally | |
344 | accompany the operating system. Such a contradiction means you cannot | |
345 | use both them and the Library together in an executable that you | |
346 | distribute. | |
347 | ||
348 | @item | |
349 | You may place library facilities that are a work based on the | |
350 | Library side-by-side in a single library together with other library | |
351 | facilities not covered by this License, and distribute such a combined | |
352 | library, provided that the separate distribution of the work based on | |
353 | the Library and of the other library facilities is otherwise | |
354 | permitted, and provided that you do these two things: | |
355 | ||
356 | @enumerate a | |
357 | @item | |
358 | Accompany the combined library with a copy of the same work | |
359 | based on the Library, uncombined with any other library | |
360 | facilities. This must be distributed under the terms of the | |
361 | Sections above. | |
362 | ||
363 | @item | |
364 | Give prominent notice with the combined library of the fact | |
365 | that part of it is a work based on the Library, and explaining | |
366 | where to find the accompanying uncombined form of the same work. | |
367 | @end enumerate | |
368 | ||
369 | @item | |
370 | You may not copy, modify, sublicense, link with, or distribute | |
371 | the Library except as expressly provided under this License. Any | |
372 | attempt otherwise to copy, modify, sublicense, link with, or | |
373 | distribute the Library is void, and will automatically terminate your | |
374 | rights under this License. However, parties who have received copies, | |
375 | or rights, from you under this License will not have their licenses | |
376 | terminated so long as such parties remain in full compliance. | |
377 | ||
378 | @item | |
379 | You are not required to accept this License, since you have not | |
380 | signed it. However, nothing else grants you permission to modify or | |
381 | distribute the Library or its derivative works. These actions are | |
382 | prohibited by law if you do not accept this License. Therefore, by | |
383 | modifying or distributing the Library (or any work based on the | |
384 | Library), you indicate your acceptance of this License to do so, and | |
385 | all its terms and conditions for copying, distributing or modifying | |
386 | the Library or works based on it. | |
387 | ||
388 | @item | |
389 | Each time you redistribute the Library (or any work based on the | |
390 | Library), the recipient automatically receives a license from the | |
391 | original licensor to copy, distribute, link with or modify the Library | |
392 | subject to these terms and conditions. You may not impose any further | |
393 | restrictions on the recipients' exercise of the rights granted herein. | |
394 | You are not responsible for enforcing compliance by third parties to | |
395 | this License. | |
396 | ||
397 | @item | |
398 | If, as a consequence of a court judgment or allegation of patent | |
399 | infringement or for any other reason (not limited to patent issues), | |
400 | conditions are imposed on you (whether by court order, agreement or | |
401 | otherwise) that contradict the conditions of this License, they do not | |
402 | excuse you from the conditions of this License. If you cannot | |
403 | distribute so as to satisfy simultaneously your obligations under this | |
404 | License and any other pertinent obligations, then as a consequence you | |
405 | may not distribute the Library at all. For example, if a patent | |
406 | license would not permit royalty-free redistribution of the Library by | |
407 | all those who receive copies directly or indirectly through you, then | |
408 | the only way you could satisfy both it and this License would be to | |
409 | refrain entirely from distribution of the Library. | |
410 | ||
411 | If any portion of this section is held invalid or unenforceable under any | |
412 | particular circumstance, the balance of the section is intended to apply, | |
413 | and the section as a whole is intended to apply in other circumstances. | |
414 | ||
415 | It is not the purpose of this section to induce you to infringe any | |
416 | patents or other property right claims or to contest validity of any | |
417 | such claims; this section has the sole purpose of protecting the | |
418 | integrity of the free software distribution system which is | |
419 | implemented by public license practices. Many people have made | |
420 | generous contributions to the wide range of software distributed | |
421 | through that system in reliance on consistent application of that | |
422 | system; it is up to the author/donor to decide if he or she is willing | |
423 | to distribute software through any other system and a licensee cannot | |
424 | impose that choice. | |
425 | ||
426 | This section is intended to make thoroughly clear what is believed to | |
427 | be a consequence of the rest of this License. | |
428 | ||
429 | @item | |
430 | If the distribution and/or use of the Library is restricted in | |
431 | certain countries either by patents or by copyrighted interfaces, the | |
432 | original copyright holder who places the Library under this License may add | |
433 | an explicit geographical distribution limitation excluding those countries, | |
434 | so that distribution is permitted only in or among countries not thus | |
435 | excluded. In such case, this License incorporates the limitation as if | |
436 | written in the body of this License. | |
437 | ||
438 | @item | |
439 | The Free Software Foundation may publish revised and/or new | |
440 | versions of the Library General Public License from time to time. | |
441 | Such new versions will be similar in spirit to the present version, | |
442 | but may differ in detail to address new problems or concerns. | |
443 | ||
444 | Each version is given a distinguishing version number. If the Library | |
445 | specifies a version number of this License which applies to it and | |
446 | ``any later version'', you have the option of following the terms and | |
447 | conditions either of that version or of any later version published by | |
448 | the Free Software Foundation. If the Library does not specify a | |
449 | license version number, you may choose any version ever published by | |
450 | the Free Software Foundation. | |
451 | ||
452 | @item | |
453 | If you wish to incorporate parts of the Library into other free | |

496 | @unnumberedsec How to Apply These Terms to Your New Libraries | |
497 | ||
498 | If you develop a new library, and you want it to be of the greatest | |
499 | possible use to the public, we recommend making it free software that | |
500 | everyone can redistribute and change. You can do so by permitting | |
501 | redistribution under these terms (or, alternatively, under the terms of the | |
502 | ordinary General Public License). | |
503 | ||
504 | To apply these terms, attach the following notices to the library. It is | |
505 | safest to attach them to the start of each source file to most effectively | |
506 | convey the exclusion of warranty; and each file should have at least the | |
507 | ``copyright'' line and a pointer to where the full notice is found. | |

519 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |

528 | ||
529 | Also add information on how to contact you by electronic and paper mail. | |
530 | ||
531 | You should also get your employer (if you work as a programmer) or your | |
532 | school, if any, to sign a ``copyright disclaimer'' for the library, if | |
533 | necessary. Here is a sample; alter the names: | |
534 | ||
535 | @example | |
536 | Yoyodyne, Inc., hereby disclaims all copyright interest in | |
537 | the library `Frob' (a library for tweaking knobs) written | |
538 | by James Random Hacker. | |
