6 | Everyone is permitted to copy and distribute verbatim copies |
7 | of this license document, but changing it is not allowed. | |
8 | ||
9 | [This is the first released version of the Lesser GPL. It also counts | |
10 | as the successor of the GNU Library Public License, version 2, hence | |
11 | the version number 2.1.] | |
12 | ||
13 | Preamble | |
14 | ||
15 | The licenses for most software are designed to take away your | |
16 | freedom to share and change it. By contrast, the GNU General Public | |
17 | Licenses are intended to guarantee your freedom to share and change | |
18 | free software--to make sure the software is free for all its users. | |
19 | ||
20 | This license, the Lesser General Public License, applies to some | |
21 | specially designated software packages--typically libraries--of the | |
22 | Free Software Foundation and other authors who decide to use it. You | |
23 | can use it too, but we suggest you first think carefully about whether | |
24 | this license or the ordinary General Public License is the better | |
6126a412 | 25 | strategy to use in any particular case, based on the explanations below. |
5430f7f2 LP |
26 | |
27 | When we speak of free software, we are referring to freedom of use, | |
28 | not price. Our General Public Licenses are designed to make sure that | |
29 | you have the freedom to distribute copies of free software (and charge | |
30 | for this service if you wish); that you receive source code or can get | |
31 | it if you want it; that you can change the software and use pieces of | |
32 | it in new free programs; and that you are informed that you can do | |
33 | these things. | |
34 | ||
35 | To protect your rights, we need to make restrictions that forbid | |
36 | distributors to deny you these rights or to ask you to surrender these | |
37 | rights. These restrictions translate to certain responsibilities for | |
38 | you if you distribute copies of the library or if you modify it. | |
39 | ||
40 | For example, if you distribute copies of the library, whether gratis | |
41 | or for a fee, you must give the recipients all the rights that we gave | |
42 | you. You must make sure that they, too, receive or can get the source | |
43 | code. If you link other code with the library, you must provide | |
44 | complete object files to the recipients, so that they can relink them | |
45 | with the library after making changes to the library and recompiling | |
46 | it. And you must show them these terms so they know their rights. | |
47 | ||
48 | We protect your rights with a two-step method: (1) we copyright the | |
49 | library, and (2) we offer you this license, which gives you legal | |
50 | permission to copy, distribute and/or modify the library. | |
51 | ||
52 | To protect each distributor, we want to make it very clear that | |
53 | there is no warranty for the free library. Also, if the library is | |
54 | modified by someone else and passed on, the recipients should know | |
55 | that what they have is not the original version, so that the original | |
56 | author's reputation will not be affected by problems that might be | |
57 | introduced by others. | |
6126a412 | 58 | \f |
5430f7f2 LP |
59 | Finally, software patents pose a constant threat to the existence of |
60 | any free program. We wish to make sure that a company cannot | |
61 | effectively restrict the users of a free program by obtaining a | |
62 | restrictive license from a patent holder. Therefore, we insist that | |
63 | any patent license obtained for a version of the library must be | |
64 | consistent with the full freedom of use specified in this license. | |
65 | ||
66 | Most GNU software, including some libraries, is covered by the | |
67 | ordinary GNU General Public License. This license, the GNU Lesser | |
68 | General Public License, applies to certain designated libraries, and | |
69 | is quite different from the ordinary General Public License. We use | |
70 | this license for certain libraries in order to permit linking those | |
71 | libraries into non-free programs. | |
72 | ||
73 | When a program is linked with a library, whether statically or using | |
74 | a shared library, the combination of the two is legally speaking a | |
75 | combined work, a derivative of the original library. The ordinary | |
76 | General Public License therefore permits such linking only if the | |
77 | entire combination fits its criteria of freedom. The Lesser General | |
78 | Public License permits more lax criteria for linking other code with | |
79 | the library. | |
80 | ||
81 | We call this license the "Lesser" General Public License because it | |
82 | does Less to protect the user's freedom than the ordinary General | |
83 | Public License. It also provides other free software developers Less | |
84 | of an advantage over competing non-free programs. These disadvantages | |
85 | are the reason we use the ordinary General Public License for many | |
86 | libraries. However, the Lesser license provides advantages in certain | |
87 | special circumstances. | |
88 | ||
89 | For example, on rare occasions, there may be a special need to | |
6126a412 RR |
90 | encourage the widest possible use of a certain library, so that it becomes |
91 | a de-facto standard. To achieve this, non-free programs must be | |
92 | allowed to use the library. A more frequent case is that a free | |
5430f7f2 LP |
93 | library does the same job as widely used non-free libraries. In this |
94 | case, there is little to gain by limiting the free library to free | |
95 | software only, so we use the Lesser General Public License. | |
96 | ||
97 | In other cases, permission to use a particular library in non-free | |
98 | programs enables a greater number of people to use a large body of | |
99 | free software. For example, permission to use the GNU C Library in | |
100 | non-free programs enables many more people to use the whole GNU | |
101 | operating system, as well as its variant, the GNU/Linux operating | |
102 | system. | |
103 | ||
104 | Although the Lesser General Public License is Less protective of the | |
105 | users' freedom, it does ensure that the user of a program that is | |
106 | linked with the Library has the freedom and the wherewithal to run | |
107 | that program using a modified version of the Library. | |
108 | ||
109 | The precise terms and conditions for copying, distribution and | |
110 | modification follow. Pay close attention to the difference between a | |
111 | "work based on the library" and a "work that uses the library". The | |
112 | former contains code derived from the library, whereas the latter must | |
113 | be combined with the library in order to run. | |

115 | GNU LESSER GENERAL PUBLIC LICENSE |
116 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
117 | ||
118 | 0. This License Agreement applies to any software library or other | |
119 | program which contains a notice placed by the copyright holder or | |
120 | other authorized party saying it may be distributed under the terms of | |
121 | this Lesser General Public License (also called "this License"). | |
122 | Each licensee is addressed as "you". | |
123 | ||
124 | A "library" means a collection of software functions and/or data | |
125 | prepared so as to be conveniently linked with application programs | |
126 | (which use some of those functions and data) to form executables. | |
127 | ||
128 | The "Library", below, refers to any such software library or work | |
129 | which has been distributed under these terms. A "work based on the | |
130 | Library" means either the Library or any derivative work under | |
131 | copyright law: that is to say, a work containing the Library or a | |
132 | portion of it, either verbatim or with modifications and/or translated | |
133 | straightforwardly into another language. (Hereinafter, translation is | |
134 | included without limitation in the term "modification".) | |
135 | ||
136 | "Source code" for a work means the preferred form of the work for | |
137 | making modifications to it. For a library, complete source code means | |
138 | all the source code for all modules it contains, plus any associated | |
6126a412 RR |
139 | interface definition files, plus the scripts used to control compilation |
140 | and installation of the library. | |
5430f7f2 LP |
141 | |
142 | Activities other than copying, distribution and modification are not | |
143 | covered by this License; they are outside its scope. The act of | |
144 | running a program using the Library is not restricted, and output from | |
145 | such a program is covered only if its contents constitute a work based | |
146 | on the Library (independent of the use of the Library in a tool for | |
147 | writing it). Whether that is true depends on what the Library does | |
148 | and what the program that uses the Library does. | |
149 | ||
150 | 1. You may copy and distribute verbatim copies of the Library's | |
151 | complete source code as you receive it, in any medium, provided that | |
152 | you conspicuously and appropriately publish on each copy an | |
153 | appropriate copyright notice and disclaimer of warranty; keep intact | |
154 | all the notices that refer to this License and to the absence of any | |
155 | warranty; and distribute a copy of this License along with the | |
156 | Library. | |
157 | ||
158 | You may charge a fee for the physical act of transferring a copy, | |
159 | and you may at your option offer warranty protection in exchange for a | |
160 | fee. | |
161 | \f | |
162 | 2. You may modify your copy or copies of the Library or any portion | |
163 | of it, thus forming a work based on the Library, and copy and | |
164 | distribute such modifications or work under the terms of Section 1 | |
165 | above, provided that you also meet all of these conditions: | |
166 | ||
167 | a) The modified work must itself be a software library. | |
168 | ||
169 | b) You must cause the files modified to carry prominent notices | |
170 | stating that you changed the files and the date of any change. | |
171 | ||
172 | c) You must cause the whole of the work to be licensed at no | |
173 | charge to all third parties under the terms of this License. | |
174 | ||
175 | d) If a facility in the modified Library refers to a function or a | |
176 | table of data to be supplied by an application program that uses | |
177 | the facility, other than as an argument passed when the facility | |
178 | is invoked, then you must make a good faith effort to ensure that, | |
179 | in the event an application does not supply such function or | |
180 | table, the facility still operates, and performs whatever part of | |
181 | its purpose remains meaningful. | |
182 | ||
183 | (For example, a function in a library to compute square roots has | |
184 | a purpose that is entirely well-defined independent of the | |
185 | application. Therefore, Subsection 2d requires that any | |
186 | application-supplied function or table used by this function must | |
187 | be optional: if the application does not supply it, the square | |
188 | root function must still compute square roots.) | |
189 | ||
190 | These requirements apply to the modified work as a whole. If | |
191 | identifiable sections of that work are not derived from the Library, | |
192 | and can be reasonably considered independent and separate works in | |
193 | themselves, then this License, and its terms, do not apply to those | |
194 | sections when you distribute them as separate works. But when you | |
195 | distribute the same sections as part of a whole which is a work based | |
196 | on the Library, the distribution of the whole must be on the terms of | |
197 | this License, whose permissions for other licensees extend to the | |
198 | entire whole, and thus to each and every part regardless of who wrote | |
199 | it. | |
200 | ||
201 | Thus, it is not the intent of this section to claim rights or contest | |
202 | your rights to work written entirely by you; rather, the intent is to | |
203 | exercise the right to control the distribution of derivative or | |
204 | collective works based on the Library. | |
205 | ||
206 | In addition, mere aggregation of another work not based on the Library | |
207 | with the Library (or with a work based on the Library) on a volume of | |
208 | a storage or distribution medium does not bring the other work under | |
209 | the scope of this License. | |
210 | ||
211 | 3. You may opt to apply the terms of the ordinary GNU General Public | |
212 | License instead of this License to a given copy of the Library. To do | |
213 | this, you must alter all the notices that refer to this License, so | |
214 | that they refer to the ordinary GNU General Public License, version 2, | |
215 | instead of to this License. (If a newer version than version 2 of the | |
216 | ordinary GNU General Public License has appeared, then you can specify | |
217 | that version instead if you wish.) Do not make any other change in | |
218 | these notices. | |
6126a412 | 219 | \f |
5430f7f2 LP |
220 | Once this change is made in a given copy, it is irreversible for |
221 | that copy, so the ordinary GNU General Public License applies to all | |
222 | subsequent copies and derivative works made from that copy. | |
223 | ||
224 | This option is useful when you wish to copy part of the code of | |
225 | the Library into a program that is not a library. | |
226 | ||
227 | 4. You may copy and distribute the Library (or a portion or | |
228 | derivative of it, under Section 2) in object code or executable form | |
229 | under the terms of Sections 1 and 2 above provided that you accompany | |
230 | it with the complete corresponding machine-readable source code, which | |
231 | must be distributed under the terms of Sections 1 and 2 above on a | |
232 | medium customarily used for software interchange. | |
233 | ||
234 | If distribution of object code is made by offering access to copy | |
235 | from a designated place, then offering equivalent access to copy the | |
236 | source code from the same place satisfies the requirement to | |
237 | distribute the source code, even though third parties are not | |
238 | compelled to copy the source along with the object code. | |
239 | ||
240 | 5. A program that contains no derivative of any portion of the | |
241 | Library, but is designed to work with the Library by being compiled or | |
242 | linked with it, is called a "work that uses the Library". Such a | |
243 | work, in isolation, is not a derivative work of the Library, and | |
244 | therefore falls outside the scope of this License. | |
245 | ||
246 | However, linking a "work that uses the Library" with the Library | |
247 | creates an executable that is a derivative of the Library (because it | |
248 | contains portions of the Library), rather than a "work that uses the | |
249 | library". The executable is therefore covered by this License. | |
250 | Section 6 states terms for distribution of such executables. | |
251 | ||
252 | When a "work that uses the Library" uses material from a header file | |
253 | that is part of the Library, the object code for the work may be a | |
254 | derivative work of the Library even though the source code is not. | |
255 | Whether this is true is especially significant if the work can be | |
256 | linked without the Library, or if the work is itself a library. The | |
257 | threshold for this to be true is not precisely defined by law. | |
258 | ||
259 | If such an object file uses only numerical parameters, data | |
260 | structure layouts and accessors, and small macros and small inline | |
261 | functions (ten lines or less in length), then the use of the object | |
262 | file is unrestricted, regardless of whether it is legally a derivative | |
263 | work. (Executables containing this object code plus portions of the | |
264 | Library will still fall under Section 6.) | |
265 | ||
266 | Otherwise, if the work is a derivative of the Library, you may | |
267 | distribute the object code for the work under the terms of Section 6. | |
268 | Any executables containing that work also fall under Section 6, | |
269 | whether or not they are linked directly with the Library itself. | |
6126a412 | 270 | \f |
5430f7f2 LP |
271 | 6. As an exception to the Sections above, you may also combine or |
272 | link a "work that uses the Library" with the Library to produce a | |
273 | work containing portions of the Library, and distribute that work | |
274 | under terms of your choice, provided that the terms permit | |
275 | modification of the work for the customer's own use and reverse | |
276 | engineering for debugging such modifications. | |
277 | ||
278 | You must give prominent notice with each copy of the work that the | |
279 | Library is used in it and that the Library and its use are covered by | |
280 | this License. You must supply a copy of this License. If the work | |
281 | during execution displays copyright notices, you must include the | |
282 | copyright notice for the Library among them, as well as a reference | |
283 | directing the user to the copy of this License. Also, you must do one | |
284 | of these things: | |
285 | ||
286 | a) Accompany the work with the complete corresponding | |
287 | machine-readable source code for the Library including whatever | |
288 | changes were used in the work (which must be distributed under | |
289 | Sections 1 and 2 above); and, if the work is an executable linked | |
290 | with the Library, with the complete machine-readable "work that | |
291 | uses the Library", as object code and/or source code, so that the | |
292 | user can modify the Library and then relink to produce a modified | |
293 | executable containing the modified Library. (It is understood | |
294 | that the user who changes the contents of definitions files in the | |
295 | Library will not necessarily be able to recompile the application | |
296 | to use the modified definitions.) | |
297 | ||
298 | b) Use a suitable shared library mechanism for linking with the | |
299 | Library. A suitable mechanism is one that (1) uses at run time a | |
300 | copy of the library already present on the user's computer system, | |
301 | rather than copying library functions into the executable, and (2) | |
302 | will operate properly with a modified version of the library, if | |
303 | the user installs one, as long as the modified version is | |
304 | interface-compatible with the version that the work was made with. | |
305 | ||
6126a412 RR |
306 | c) Accompany the work with a written offer, valid for at |
307 | least three years, to give the same user the materials | |
308 | specified in Subsection 6a, above, for a charge no more | |
309 | than the cost of performing this distribution. | |
5430f7f2 LP |
310 | |
311 | d) If distribution of the work is made by offering access to copy | |
312 | from a designated place, offer equivalent access to copy the above | |
313 | specified materials from the same place. | |
314 | ||
315 | e) Verify that the user has already received a copy of these | |
316 | materials or that you have already sent this user a copy. | |
317 | ||
318 | For an executable, the required form of the "work that uses the | |
319 | Library" must include any data and utility programs needed for | |
320 | reproducing the executable from it. However, as a special exception, | |
321 | the materials to be distributed need not include anything that is | |
322 | normally distributed (in either source or binary form) with the major | |
323 | components (compiler, kernel, and so on) of the operating system on | |
324 | which the executable runs, unless that component itself accompanies | |
325 | the executable. | |
326 | ||
327 | It may happen that this requirement contradicts the license | |
328 | restrictions of other proprietary libraries that do not normally | |
329 | accompany the operating system. Such a contradiction means you cannot | |
330 | use both them and the Library together in an executable that you | |
331 | distribute. | |
6126a412 | 332 | \f |
5430f7f2 LP |
333 | 7. You may place library facilities that are a work based on the |
334 | Library side-by-side in a single library together with other library | |
335 | facilities not covered by this License, and distribute such a combined | |
336 | library, provided that the separate distribution of the work based on | |
337 | the Library and of the other library facilities is otherwise | |
338 | permitted, and provided that you do these two things: | |
339 | ||
340 | a) Accompany the combined library with a copy of the same work | |
341 | based on the Library, uncombined with any other library | |
342 | facilities. This must be distributed under the terms of the | |
343 | Sections above. | |
344 | ||
345 | b) Give prominent notice with the combined library of the fact | |
346 | that part of it is a work based on the Library, and explaining | |
347 | where to find the accompanying uncombined form of the same work. | |
348 | ||
349 | 8. You may not copy, modify, sublicense, link with, or distribute | |
350 | the Library except as expressly provided under this License. Any | |
351 | attempt otherwise to copy, modify, sublicense, link with, or | |
352 | distribute the Library is void, and will automatically terminate your | |
353 | rights under this License. However, parties who have received copies, | |
354 | or rights, from you under this License will not have their licenses | |
355 | terminated so long as such parties remain in full compliance. | |
356 | ||
357 | 9. You are not required to accept this License, since you have not | |
358 | signed it. However, nothing else grants you permission to modify or | |
359 | distribute the Library or its derivative works. These actions are | |
360 | prohibited by law if you do not accept this License. Therefore, by | |
361 | modifying or distributing the Library (or any work based on the | |
362 | Library), you indicate your acceptance of this License to do so, and | |
363 | all its terms and conditions for copying, distributing or modifying | |
364 | the Library or works based on it. | |
365 | ||
366 | 10. Each time you redistribute the Library (or any work based on the | |
367 | Library), the recipient automatically receives a license from the | |
368 | original licensor to copy, distribute, link with or modify the Library | |
369 | subject to these terms and conditions. You may not impose any further | |
370 | restrictions on the recipients' exercise of the rights granted herein. | |
371 | You are not responsible for enforcing compliance by third parties with | |
372 | this License. | |
6126a412 | 373 | \f |
5430f7f2 LP |
374 | 11. If, as a consequence of a court judgment or allegation of patent |
375 | infringement or for any other reason (not limited to patent issues), | |
376 | conditions are imposed on you (whether by court order, agreement or | |
377 | otherwise) that contradict the conditions of this License, they do not | |
378 | excuse you from the conditions of this License. If you cannot | |
379 | distribute so as to satisfy simultaneously your obligations under this | |
380 | License and any other pertinent obligations, then as a consequence you | |
381 | may not distribute the Library at all. For example, if a patent | |
382 | license would not permit royalty-free redistribution of the Library by | |
383 | all those who receive copies directly or indirectly through you, then | |
384 | the only way you could satisfy both it and this License would be to | |
385 | refrain entirely from distribution of the Library. | |
386 | ||
6126a412 RR |
387 | If any portion of this section is held invalid or unenforceable under any |
388 | particular circumstance, the balance of the section is intended to apply, | |
389 | and the section as a whole is intended to apply in other circumstances. | |
5430f7f2 LP |
390 | |
391 | It is not the purpose of this section to induce you to infringe any | |
392 | patents or other property right claims or to contest validity of any | |
393 | such claims; this section has the sole purpose of protecting the | |
394 | integrity of the free software distribution system which is | |
395 | implemented by public license practices. Many people have made | |
396 | generous contributions to the wide range of software distributed | |
397 | through that system in reliance on consistent application of that | |
398 | system; it is up to the author/donor to decide if he or she is willing | |
399 | to distribute software through any other system and a licensee cannot | |
400 | impose that choice. | |
401 | ||
402 | This section is intended to make thoroughly clear what is believed to | |
403 | be a consequence of the rest of this License. | |
404 | ||
405 | 12. If the distribution and/or use of the Library is restricted in | |
406 | certain countries either by patents or by copyrighted interfaces, the | |
6126a412 RR |
407 | original copyright holder who places the Library under this License may add |
408 | an explicit geographical distribution limitation excluding those countries, | |
409 | so that distribution is permitted only in or among countries not thus | |
410 | excluded. In such case, this License incorporates the limitation as if | |
411 | written in the body of this License. | |
5430f7f2 LP |
412 | |
413 | 13. The Free Software Foundation may publish revised and/or new | |
414 | versions of the Lesser General Public License from time to time. | |
415 | Such new versions will be similar in spirit to the present version, | |

418 | Each version is given a distinguishing version number. If the Library | |
419 | specifies a version number of this License which applies to it and | |
420 | "any later version", you have the option of following the terms and | |
421 | conditions either of that version or of any later version published by | |
422 | the Free Software Foundation. If the Library does not specify a | |
423 | license version number, you may choose any version ever published by | |
424 | the Free Software Foundation. | |

426 | 14. If you wish to incorporate parts of the Library into other free |
427 | programs whose distribution conditions are incompatible with these, | |
428 | write to the author to ask for permission. For software which is | |
429 | copyrighted by the Free Software Foundation, write to the Free | |
430 | Software Foundation; we sometimes make exceptions for this. Our | |
431 | decision will be guided by the two goals of preserving the free status | |
432 | of all derivatives of our free software and of promoting the sharing | |
433 | and reuse of software generally. | |

438 | WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. | |

440 | OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY | |
441 | KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE | |
442 | IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
443 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE | |
444 | LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME | |
445 | THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
446 | ||
447 | 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN | |
448 | WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY | |
449 | AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU | |
450 | FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR | |
451 | CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE | |
452 | LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING | |
453 | RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A | |
454 | FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF | |

460 | How to Apply These Terms to Your New Libraries |
461 | ||
462 | If you develop a new library, and you want it to be of the greatest | |
463 | possible use to the public, we recommend making it free software that | |
464 | everyone can redistribute and change. You can do so by permitting | |
6126a412 RR |
465 | redistribution under these terms (or, alternatively, under the terms of the |
466 | ordinary General Public License). | |
5430f7f2 | 467 | |
6126a412 RR |
468 | To apply these terms, attach the following notices to the library. It is |
469 | safest to attach them to the start of each source file to most effectively | |
470 | convey the exclusion of warranty; and each file should have at least the | |
471 | "copyright" line and a pointer to where the full notice is found. | |

492 | You should also get your employer (if you work as a programmer) or your |
493 | school, if any, to sign a "copyright disclaimer" for the library, if | |
494 | necessary. Here is a sample; alter the names: | |
