122 Each licensee is addressed as "you". |
0 | 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 | |
139 interface definition files, plus the scripts used to control compilation | |
140 and installation of the library. | |
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 | |
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. | |
219 | |
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. | |
270 | |

271 6. As an exception to the Sections above, you may also combine or |
0 | 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.) | |

322 normally distributed (in either source or binary form) with the major |
0 | 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. | |
332 | |
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 |
0 | 372 this License. |
373 | |
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 | |
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. | |
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 | |
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. | |
412 | |

414 versions of the Lesser General Public License from time to time. |
0 | 415 Such new versions will be similar in spirit to the present version, |
416 but may differ in detail to address new problems or concerns. | |
417 | |
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. | |
425 | |
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. | |
434 | |
435 NO WARRANTY | |
436 | |
437 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO | |
438 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. | |
439 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR | |
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 | |
455 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH | |
456 DAMAGES. | |
