11 | as the successor of the GNU Library Public License, version 2, hence | |
12 | the version number 2.1.] | |

a1b36134 | 14 | Preamble |
97a0d44d UD |
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 | ||
a1b36134 AJ |
21 | This license, the Lesser General Public License, applies to some |
22 | specially designated software packages--typically libraries--of the | |
23 | Free Software Foundation and other authors who decide to use it. You | |
24 | can use it too, but we suggest you first think carefully about whether | |
25 | this license or the ordinary General Public License is the better | |
26 | strategy to use in any particular case, based on the explanations | |
27 | below. | |
28 | ||
29 | When we speak of free software, we are referring to freedom of use, | |
30 | not price. Our General Public Licenses are designed to make sure that | |
31 | you have the freedom to distribute copies of free software (and charge | |
32 | for this service if you wish); that you receive source code or can get | |
33 | it if you want it; that you can change the software and use pieces of | |
34 | it in new free programs; and that you are informed that you can do | |
35 | these things. | |
97a0d44d UD |
36 | |
37 | To protect your rights, we need to make restrictions that forbid | |
a1b36134 AJ |
38 | distributors to deny you these rights or to ask you to surrender these |
39 | rights. These restrictions translate to certain responsibilities for | |
40 | you if you distribute copies of the library or if you modify it. | |
97a0d44d UD |
41 | |
42 | For example, if you distribute copies of the library, whether gratis | |
43 | or for a fee, you must give the recipients all the rights that we gave | |
44 | you. You must make sure that they, too, receive or can get the source | |
a1b36134 AJ |
45 | code. If you link other code with the library, you must provide |
46 | complete object files to the recipients, so that they can relink them | |
47 | with the library after making changes to the library and recompiling | |
97a0d44d UD |
48 | it. And you must show them these terms so they know their rights. |
49 | ||
a1b36134 AJ |
50 | We protect your rights with a two-step method: (1) we copyright the |
51 | library, and (2) we offer you this license, which gives you legal | |
97a0d44d UD |
52 | permission to copy, distribute and/or modify the library. |
53 | ||
a1b36134 AJ |
54 | To protect each distributor, we want to make it very clear that |
55 | there is no warranty for the free library. Also, if the library is | |
56 | modified by someone else and passed on, the recipients should know | |
57 | that what they have is not the original version, so that the original | |
58 | author's reputation will not be affected by problems that might be | |
59 | introduced by others. | |
60 | ^L | |
61 | Finally, software patents pose a constant threat to the existence of | |
62 | any free program. We wish to make sure that a company cannot | |
63 | effectively restrict the users of a free program by obtaining a | |
64 | restrictive license from a patent holder. Therefore, we insist that | |
65 | any patent license obtained for a version of the library must be | |
66 | consistent with the full freedom of use specified in this license. | |
67 | ||
68 | Most GNU software, including some libraries, is covered by the | |
69 | ordinary GNU General Public License. This license, the GNU Lesser | |
70 | General Public License, applies to certain designated libraries, and | |
71 | is quite different from the ordinary General Public License. We use | |
72 | this license for certain libraries in order to permit linking those | |
73 | libraries into non-free programs. | |
74 | ||
75 | When a program is linked with a library, whether statically or using | |
76 | a shared library, the combination of the two is legally speaking a | |
77 | combined work, a derivative of the original library. The ordinary | |
78 | General Public License therefore permits such linking only if the | |
79 | entire combination fits its criteria of freedom. The Lesser General | |
80 | Public License permits more lax criteria for linking other code with | |
81 | the library. | |
82 | ||
83 | We call this license the "Lesser" General Public License because it | |
84 | does Less to protect the user's freedom than the ordinary General | |
85 | Public License. It also provides other free software developers Less | |
86 | of an advantage over competing non-free programs. These disadvantages | |
87 | are the reason we use the ordinary General Public License for many | |
88 | libraries. However, the Lesser license provides advantages in certain | |
89 | special circumstances. | |
90 | ||
91 | For example, on rare occasions, there may be a special need to | |
92 | encourage the widest possible use of a certain library, so that it | |
cc7375ce RM |
93 | becomes a de-facto standard. To achieve this, non-free programs must |
94 | be allowed to use the library. A more frequent case is that a free | |
a1b36134 AJ |
95 | library does the same job as widely used non-free libraries. In this |
96 | case, there is little to gain by limiting the free library to free | |
97 | software only, so we use the Lesser General Public License. | |
98 | ||
99 | In other cases, permission to use a particular library in non-free | |
100 | programs enables a greater number of people to use a large body of | |
101 | free software. For example, permission to use the GNU C Library in | |
102 | non-free programs enables many more people to use the whole GNU | |
103 | operating system, as well as its variant, the GNU/Linux operating | |
104 | system. | |
105 | ||
106 | Although the Lesser General Public License is Less protective of the | |
107 | users' freedom, it does ensure that the user of a program that is | |
108 | linked with the Library has the freedom and the wherewithal to run | |
109 | that program using a modified version of the Library. | |
97a0d44d UD |
110 | |
111 | The precise terms and conditions for copying, distribution and | |
112 | modification follow. Pay close attention to the difference between a | |
113 | "work based on the library" and a "work that uses the library". The | |
a1b36134 AJ |
114 | former contains code derived from the library, whereas the latter must |
115 | be combined with the library in order to run. | |
116 | ^L | |
117 | GNU LESSER GENERAL PUBLIC LICENSE | |
97a0d44d UD |
118 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
119 | ||
a1b36134 AJ |
120 | 0. This License Agreement applies to any software library or other |
121 | program which contains a notice placed by the copyright holder or | |
122 | other authorized party saying it may be distributed under the terms of | |
123 | this Lesser General Public License (also called "this License"). | |
124 | Each licensee is addressed as "you". | |
97a0d44d UD |
125 | |
126 | A "library" means a collection of software functions and/or data | |
127 | prepared so as to be conveniently linked with application programs | |
128 | (which use some of those functions and data) to form executables. | |
129 | ||
130 | The "Library", below, refers to any such software library or work | |
131 | which has been distributed under these terms. A "work based on the | |
132 | Library" means either the Library or any derivative work under | |
133 | copyright law: that is to say, a work containing the Library or a | |
134 | portion of it, either verbatim or with modifications and/or translated | |
135 | straightforwardly into another language. (Hereinafter, translation is | |
136 | included without limitation in the term "modification".) | |
137 | ||
138 | "Source code" for a work means the preferred form of the work for | |
139 | making modifications to it. For a library, complete source code means | |
140 | all the source code for all modules it contains, plus any associated | |
a1b36134 | 141 | interface definition files, plus the scripts used to control |
cc7375ce | 142 | compilation and installation of the library. |
97a0d44d UD |
143 | |
144 | Activities other than copying, distribution and modification are not | |
145 | covered by this License; they are outside its scope. The act of | |
146 | running a program using the Library is not restricted, and output from | |
147 | such a program is covered only if its contents constitute a work based | |
148 | on the Library (independent of the use of the Library in a tool for | |
149 | writing it). Whether that is true depends on what the Library does | |
150 | and what the program that uses the Library does. | |
a1b36134 | 151 | |
97a0d44d UD |
152 | 1. You may copy and distribute verbatim copies of the Library's |
153 | complete source code as you receive it, in any medium, provided that | |
154 | you conspicuously and appropriately publish on each copy an | |
155 | appropriate copyright notice and disclaimer of warranty; keep intact | |
156 | all the notices that refer to this License and to the absence of any | |
157 | warranty; and distribute a copy of this License along with the | |
158 | Library. | |
159 | ||
160 | You may charge a fee for the physical act of transferring a copy, | |
161 | and you may at your option offer warranty protection in exchange for a | |
162 | fee. | |
163 | \f | |
164 | 2. You may modify your copy or copies of the Library or any portion | |
165 | of it, thus forming a work based on the Library, and copy and | |
166 | distribute such modifications or work under the terms of Section 1 | |
167 | above, provided that you also meet all of these conditions: | |
168 | ||
169 | a) The modified work must itself be a software library. | |
170 | ||
171 | b) You must cause the files modified to carry prominent notices | |
172 | stating that you changed the files and the date of any change. | |
173 | ||
174 | c) You must cause the whole of the work to be licensed at no | |
175 | charge to all third parties under the terms of this License. | |
176 | ||
177 | d) If a facility in the modified Library refers to a function or a | |
178 | table of data to be supplied by an application program that uses | |
179 | the facility, other than as an argument passed when the facility | |
180 | is invoked, then you must make a good faith effort to ensure that, | |
181 | in the event an application does not supply such function or | |
182 | table, the facility still operates, and performs whatever part of | |
183 | its purpose remains meaningful. | |
184 | ||
185 | (For example, a function in a library to compute square roots has | |
186 | a purpose that is entirely well-defined independent of the | |
187 | application. Therefore, Subsection 2d requires that any | |
188 | application-supplied function or table used by this function must | |
189 | be optional: if the application does not supply it, the square | |
190 | root function must still compute square roots.) | |
191 | ||
192 | These requirements apply to the modified work as a whole. If | |
193 | identifiable sections of that work are not derived from the Library, | |
194 | and can be reasonably considered independent and separate works in | |
195 | themselves, then this License, and its terms, do not apply to those | |
196 | sections when you distribute them as separate works. But when you | |
197 | distribute the same sections as part of a whole which is a work based | |
198 | on the Library, the distribution of the whole must be on the terms of | |
199 | this License, whose permissions for other licensees extend to the | |
200 | entire whole, and thus to each and every part regardless of who wrote | |
201 | it. | |
202 | ||
203 | Thus, it is not the intent of this section to claim rights or contest | |
204 | your rights to work written entirely by you; rather, the intent is to | |
205 | exercise the right to control the distribution of derivative or | |
206 | collective works based on the Library. | |
207 | ||
208 | In addition, mere aggregation of another work not based on the Library | |
209 | with the Library (or with a work based on the Library) on a volume of | |
210 | a storage or distribution medium does not bring the other work under | |
211 | the scope of this License. | |
212 | ||
213 | 3. You may opt to apply the terms of the ordinary GNU General Public | |
214 | License instead of this License to a given copy of the Library. To do | |
215 | this, you must alter all the notices that refer to this License, so | |
216 | that they refer to the ordinary GNU General Public License, version 2, | |
217 | instead of to this License. (If a newer version than version 2 of the | |
218 | ordinary GNU General Public License has appeared, then you can specify | |
219 | that version instead if you wish.) Do not make any other change in | |
220 | these notices. | |
a1b36134 | 221 | ^L |
97a0d44d UD |
222 | Once this change is made in a given copy, it is irreversible for |
223 | that copy, so the ordinary GNU General Public License applies to all | |
224 | subsequent copies and derivative works made from that copy. | |
225 | ||
226 | This option is useful when you wish to copy part of the code of | |
227 | the Library into a program that is not a library. | |
228 | ||
229 | 4. You may copy and distribute the Library (or a portion or | |
230 | derivative of it, under Section 2) in object code or executable form | |
231 | under the terms of Sections 1 and 2 above provided that you accompany | |
232 | it with the complete corresponding machine-readable source code, which | |
233 | must be distributed under the terms of Sections 1 and 2 above on a | |
234 | medium customarily used for software interchange. | |
235 | ||
236 | If distribution of object code is made by offering access to copy | |
237 | from a designated place, then offering equivalent access to copy the | |
238 | source code from the same place satisfies the requirement to | |
239 | distribute the source code, even though third parties are not | |
240 | compelled to copy the source along with the object code. | |
241 | ||
242 | 5. A program that contains no derivative of any portion of the | |
243 | Library, but is designed to work with the Library by being compiled or | |
244 | linked with it, is called a "work that uses the Library". Such a | |
245 | work, in isolation, is not a derivative work of the Library, and | |
246 | therefore falls outside the scope of this License. | |
247 | ||
248 | However, linking a "work that uses the Library" with the Library | |
249 | creates an executable that is a derivative of the Library (because it | |
250 | contains portions of the Library), rather than a "work that uses the | |
251 | library". The executable is therefore covered by this License. | |
252 | Section 6 states terms for distribution of such executables. | |
253 | ||
254 | When a "work that uses the Library" uses material from a header file | |
255 | that is part of the Library, the object code for the work may be a | |
256 | derivative work of the Library even though the source code is not. | |
257 | Whether this is true is especially significant if the work can be | |
258 | linked without the Library, or if the work is itself a library. The | |
259 | threshold for this to be true is not precisely defined by law. | |
260 | ||
261 | If such an object file uses only numerical parameters, data | |
262 | structure layouts and accessors, and small macros and small inline | |
263 | functions (ten lines or less in length), then the use of the object | |
264 | file is unrestricted, regardless of whether it is legally a derivative | |
265 | work. (Executables containing this object code plus portions of the | |
266 | Library will still fall under Section 6.) | |
267 | ||
268 | Otherwise, if the work is a derivative of the Library, you may | |
269 | distribute the object code for the work under the terms of Section 6. | |
270 | Any executables containing that work also fall under Section 6, | |
271 | whether or not they are linked directly with the Library itself. | |
a1b36134 AJ |
272 | ^L |
273 | 6. As an exception to the Sections above, you may also combine or | |
97a0d44d UD |
274 | link a "work that uses the Library" with the Library to produce a |
275 | work containing portions of the Library, and distribute that work | |
276 | under terms of your choice, provided that the terms permit | |
277 | modification of the work for the customer's own use and reverse | |
278 | engineering for debugging such modifications. | |
279 | ||
280 | You must give prominent notice with each copy of the work that the | |
281 | Library is used in it and that the Library and its use are covered by | |
282 | this License. You must supply a copy of this License. If the work | |
283 | during execution displays copyright notices, you must include the | |
284 | copyright notice for the Library among them, as well as a reference | |
285 | directing the user to the copy of this License. Also, you must do one | |
286 | of these things: | |
287 | ||
288 | a) Accompany the work with the complete corresponding | |
289 | machine-readable source code for the Library including whatever | |
290 | changes were used in the work (which must be distributed under | |
291 | Sections 1 and 2 above); and, if the work is an executable linked | |
292 | with the Library, with the complete machine-readable "work that | |
293 | uses the Library", as object code and/or source code, so that the | |
294 | user can modify the Library and then relink to produce a modified | |
295 | executable containing the modified Library. (It is understood | |
296 | that the user who changes the contents of definitions files in the | |
297 | Library will not necessarily be able to recompile the application | |
298 | to use the modified definitions.) | |
299 | ||
a1b36134 AJ |
300 | b) Use a suitable shared library mechanism for linking with the |
301 | Library. A suitable mechanism is one that (1) uses at run time a | |
302 | copy of the library already present on the user's computer system, | |
303 | rather than copying library functions into the executable, and (2) | |
304 | will operate properly with a modified version of the library, if | |
305 | the user installs one, as long as the modified version is | |
306 | interface-compatible with the version that the work was made with. | |
307 | ||
cc7375ce RM |
308 | c) Accompany the work with a written offer, valid for at least |
309 | three years, to give the same user the materials specified in | |
310 | Subsection 6a, above, for a charge no more than the cost of | |
311 | performing this distribution. | |
97a0d44d | 312 | |
a1b36134 | 313 | d) If distribution of the work is made by offering access to copy |
97a0d44d UD |
314 | from a designated place, offer equivalent access to copy the above |
315 | specified materials from the same place. | |
316 | ||
a1b36134 | 317 | e) Verify that the user has already received a copy of these |
97a0d44d UD |
318 | materials or that you have already sent this user a copy. |
319 | ||
320 | For an executable, the required form of the "work that uses the | |
321 | Library" must include any data and utility programs needed for | |
322 | reproducing the executable from it. However, as a special exception, | |
a1b36134 AJ |
323 | the materials to be distributed need not include anything that is |
324 | normally distributed (in either source or binary form) with the major | |
97a0d44d UD |
325 | components (compiler, kernel, and so on) of the operating system on |
326 | which the executable runs, unless that component itself accompanies | |
327 | the executable. | |
328 | ||
329 | It may happen that this requirement contradicts the license | |
330 | restrictions of other proprietary libraries that do not normally | |
331 | accompany the operating system. Such a contradiction means you cannot | |
332 | use both them and the Library together in an executable that you | |
333 | distribute. | |
a1b36134 | 334 | ^L |
97a0d44d UD |
335 | 7. You may place library facilities that are a work based on the |
336 | Library side-by-side in a single library together with other library | |
337 | facilities not covered by this License, and distribute such a combined | |
338 | library, provided that the separate distribution of the work based on | |
339 | the Library and of the other library facilities is otherwise | |
340 | permitted, and provided that you do these two things: | |
341 | ||
342 | a) Accompany the combined library with a copy of the same work | |
343 | based on the Library, uncombined with any other library | |
344 | facilities. This must be distributed under the terms of the | |
345 | Sections above. | |
346 | ||
347 | b) Give prominent notice with the combined library of the fact | |
348 | that part of it is a work based on the Library, and explaining | |
349 | where to find the accompanying uncombined form of the same work. | |
350 | ||
351 | 8. You may not copy, modify, sublicense, link with, or distribute | |
352 | the Library except as expressly provided under this License. Any | |
353 | attempt otherwise to copy, modify, sublicense, link with, or | |
354 | distribute the Library is void, and will automatically terminate your | |
355 | rights under this License. However, parties who have received copies, | |
356 | or rights, from you under this License will not have their licenses | |
357 | terminated so long as such parties remain in full compliance. | |
358 | ||
359 | 9. You are not required to accept this License, since you have not | |
360 | signed it. However, nothing else grants you permission to modify or | |
361 | distribute the Library or its derivative works. These actions are | |
362 | prohibited by law if you do not accept this License. Therefore, by | |
363 | modifying or distributing the Library (or any work based on the | |
364 | Library), you indicate your acceptance of this License to do so, and | |
365 | all its terms and conditions for copying, distributing or modifying | |
366 | the Library or works based on it. | |
367 | ||
368 | 10. Each time you redistribute the Library (or any work based on the | |
369 | Library), the recipient automatically receives a license from the | |
370 | original licensor to copy, distribute, link with or modify the Library | |
371 | subject to these terms and conditions. You may not impose any further | |
372 | restrictions on the recipients' exercise of the rights granted herein. | |
a1b36134 | 373 | You are not responsible for enforcing compliance by third parties with |
97a0d44d | 374 | this License. |
a1b36134 | 375 | ^L |
97a0d44d UD |
376 | 11. If, as a consequence of a court judgment or allegation of patent |
377 | infringement or for any other reason (not limited to patent issues), | |
378 | conditions are imposed on you (whether by court order, agreement or | |
379 | otherwise) that contradict the conditions of this License, they do not | |
380 | excuse you from the conditions of this License. If you cannot | |
381 | distribute so as to satisfy simultaneously your obligations under this | |
382 | License and any other pertinent obligations, then as a consequence you | |
383 | may not distribute the Library at all. For example, if a patent | |
384 | license would not permit royalty-free redistribution of the Library by | |
385 | all those who receive copies directly or indirectly through you, then | |
386 | the only way you could satisfy both it and this License would be to | |
387 | refrain entirely from distribution of the Library. | |
388 | ||
a1b36134 AJ |
389 | If any portion of this section is held invalid or unenforceable under |
390 | any particular circumstance, the balance of the section is intended to | |
391 | apply, and the section as a whole is intended to apply in other | |
392 | circumstances. | |
97a0d44d UD |
393 | |
394 | It is not the purpose of this section to induce you to infringe any | |
395 | patents or other property right claims or to contest validity of any | |
396 | such claims; this section has the sole purpose of protecting the | |
397 | integrity of the free software distribution system which is | |
398 | implemented by public license practices. Many people have made | |
399 | generous contributions to the wide range of software distributed | |
400 | through that system in reliance on consistent application of that | |
401 | system; it is up to the author/donor to decide if he or she is willing | |
402 | to distribute software through any other system and a licensee cannot | |
403 | impose that choice. | |
404 | ||
405 | This section is intended to make thoroughly clear what is believed to | |

410 | original copyright holder who places the Library under this License |
411 | may add an explicit geographical distribution limitation excluding those | |

418 | Such new versions will be similar in spirit to the present version, |

421 | Each version is given a distinguishing version number. If the Library | |

424 | conditions either of that version or of any later version published by | |
425 | the Free Software Foundation. If the Library does not specify a | |
426 | license version number, you may choose any version ever published by | |
427 | the Free Software Foundation. | |

431 | write to the author to ask for permission. For software which is | |
432 | copyrighted by the Free Software Foundation, write to the Free | |
433 | Software Foundation; we sometimes make exceptions for this. Our | |
434 | decision will be guided by the two goals of preserving the free status | |
435 | of all derivatives of our free software and of promoting the sharing | |
436 | and reuse of software generally. | |

463 | How to Apply These Terms to Your New Libraries | |
97a0d44d UD |
464 | |
465 | If you develop a new library, and you want it to be of the greatest | |
466 | possible use to the public, we recommend making it free software that | |
467 | everyone can redistribute and change. You can do so by permitting | |
a1b36134 AJ |
468 | redistribution under these terms (or, alternatively, under the terms |
469 | of the ordinary General Public License). | |
470 | ||
471 | To apply these terms, attach the following notices to the library. | |
472 | It is safest to attach them to the start of each source file to most | |
473 | effectively convey the exclusion of warranty; and each file should | |
474 | have at least the "copyright" line and a pointer to where the full | |
475 | notice is found. | |
