28 Preamble
|
|
|
29
|
|
|
30 The licenses for most software are designed to take away your
|
|
|
31 freedom to share and change it. By contrast, the GNU General Public
|
|
|
32 Licenses are intended to guarantee your freedom to share and change
|
|
|
33 free software--to make sure the software is free for all its users.
|
|
|
34
|
|
|
35 This license, the Lesser General Public License, applies to some
|
|
|
36 specially designated software packages--typically libraries--of the
|
|
|
37 Free Software Foundation and other authors who decide to use it. You
|
|
|
38 can use it too, but we suggest you first think carefully about whether
|
|
|
39 this license or the ordinary General Public License is the better
|
|
|
40 strategy to use in any particular case, based on the explanations below.
|
|
|
41
|
|
|
42 When we speak of free software, we are referring to freedom of use,
|
|
|
43 not price. Our General Public Licenses are designed to make sure that
|
|
|
44 you have the freedom to distribute copies of free software (and charge
|
|
|
45 for this service if you wish); that you receive source code or can get
|
|
|
46 it if you want it; that you can change the software and use pieces of
|
|
|
47 it in new free programs; and that you are informed that you can do
|
|
|
48 these things.
|
|
|
49
|
|
|
50 To protect your rights, we need to make restrictions that forbid
|
|
|
51 distributors to deny you these rights or to ask you to surrender these
|
|
|
52 rights. These restrictions translate to certain responsibilities for
|
|
|
53 you if you distribute copies of the library or if you modify it.
|
|
|
54
|
|
|
55 For example, if you distribute copies of the library, whether gratis
|
|
|
56 or for a fee, you must give the recipients all the rights that we gave
|
|
|
57 you. You must make sure that they, too, receive or can get the source
|
|
|
58 code. If you link other code with the library, you must provide
|
|
|
59 complete object files to the recipients, so that they can relink them
|
|
|
60 with the library after making changes to the library and recompiling
|
|
|
61 it. And you must show them these terms so they know their rights.
|
|
|
62
|
|
|
63 We protect your rights with a two-step method: (1) we copyright the
|
|
|
64 library, and (2) we offer you this license, which gives you legal
|
|
|
65 permission to copy, distribute and/or modify the library.
|
|
|
66
|
|
|
67 To protect each distributor, we want to make it very clear that
|
|
|
68 there is no warranty for the free library. Also, if the library is
|
|
|
69 modified by someone else and passed on, the recipients should know
|
|
|
70 that what they have is not the original version, so that the original
|
|
|
71 author's reputation will not be affected by problems that might be
|
|
|
72 introduced by others.
|
|
|
73
|
|
|
74 Finally, software patents pose a constant threat to the existence of
|
|
|
75 any free program. We wish to make sure that a company cannot
|
|
|
76 effectively restrict the users of a free program by obtaining a
|
|
|
77 restrictive license from a patent holder. Therefore, we insist that
|
|
|
78 any patent license obtained for a version of the library must be
|
|
|
79 consistent with the full freedom of use specified in this license.
|
|
|
80
|
|
|
81 Most GNU software, including some libraries, is covered by the
|
|
|
82 ordinary GNU General Public License. This license, the GNU Lesser
|
|
|
83 General Public License, applies to certain designated libraries, and
|
|
|
84 is quite different from the ordinary General Public License. We use
|
|
|
85 this license for certain libraries in order to permit linking those
|
|
|
86 libraries into non-free programs.
|
|
|
87
|
|
|
88 When a program is linked with a library, whether statically or using
|
|
|
89 a shared library, the combination of the two is legally speaking a
|
|
|
90 combined work, a derivative of the original library. The ordinary
|
|
|
91 General Public License therefore permits such linking only if the
|
|
|
92 entire combination fits its criteria of freedom. The Lesser General
|
|
|
93 Public License permits more lax criteria for linking other code with
|
|
|
94 the library.
|
|
|
95
|
|
|
96 We call this license the "Lesser" General Public License because it
|
|
|
97 does Less to protect the user's freedom than the ordinary General
|
|
|
98 Public License. It also provides other free software developers Less
|
|
|
99 of an advantage over competing non-free programs. These disadvantages
|
|
|
100 are the reason we use the ordinary General Public License for many
|
|
|
101 libraries. However, the Lesser license provides advantages in certain
|
|
|
102 special circumstances.
|
|
|
103
|
|
|
104 For example, on rare occasions, there may be a special need to
|
|
|
105 encourage the widest possible use of a certain library, so that it becomes
|
|
|
106 a de-facto standard. To achieve this, non-free programs must be
|
|
|
107 allowed to use the library. A more frequent case is that a free
|
|
|
108 library does the same job as widely used non-free libraries. In this
|
|
|
109 case, there is little to gain by limiting the free library to free
|
|
|
110 software only, so we use the Lesser General Public License.
|
|
|
111
|
|
|
112 In other cases, permission to use a particular library in non-free
|
|
|
113 programs enables a greater number of people to use a large body of
|
|
|
114 free software. For example, permission to use the GNU C Library in
|
|
|
115 non-free programs enables many more people to use the whole GNU
|
|
|
116 operating system, as well as its variant, the GNU/Linux operating
|
|
|
117 system.
|
|
|
118
|
|
|
119 Although the Lesser General Public License is Less protective of the
|
|
|
120 users' freedom, it does ensure that the user of a program that is
|
|
|
121 linked with the Library has the freedom and the wherewithal to run
|
|
|
122 that program using a modified version of the Library.
|
|
|
123
|
|
|
124 The precise terms and conditions for copying, distribution and
|
|
|
125 modification follow. Pay close attention to the difference between a
|
|
|
126 "work based on the library" and a "work that uses the library". The
|
|
|
127 former contains code derived from the library, whereas the latter must
|
|
|
128 be combined with the library in order to run.
|
|
|
129
|
|
|
130 GNU LESSER GENERAL PUBLIC LICENSE
|
|
|
131 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
|
132
|
|
|
133 0. This License Agreement applies to any software library or other
|
|
|
134 program which contains a notice placed by the copyright holder or
|
|
|
135 other authorized party saying it may be distributed under the terms of
|
|
|
136 this Lesser General Public License (also called "this License").
|
|
|
137 Each licensee is addressed as "you".
|
|
|
138
|
|
|
139 A "library" means a collection of software functions and/or data
|
|
|
140 prepared so as to be conveniently linked with application programs
|
|
|
141 (which use some of those functions and data) to form executables.
|
|
|
142
|
|
|
143 The "Library", below, refers to any such software library or work
|
|
|
144 which has been distributed under these terms. A "work based on the
|
|
|
145 Library" means either the Library or any derivative work under
|
|
|
146 copyright law: that is to say, a work containing the Library or a
|
|
|
147 portion of it, either verbatim or with modifications and/or translated
|
|
|
148 straightforwardly into another language. (Hereinafter, translation is
|
|
|
149 included without limitation in the term "modification".)
|
|
|
150
|
|
|
151 "Source code" for a work means the preferred form of the work for
|
|
|
152 making modifications to it. For a library, complete source code means
|
|
|
153 all the source code for all modules it contains, plus any associated
|
|
|
154 interface definition files, plus the scripts used to control compilation
|
|
|
155 and installation of the library.
|
|
|
156
|
|
|
157 Activities other than copying, distribution and modification are not
|
|
|
158 covered by this License; they are outside its scope. The act of
|
|
|
159 running a program using the Library is not restricted, and output from
|
|
|
160 such a program is covered only if its contents constitute a work based
|
|
|
161 on the Library (independent of the use of the Library in a tool for
|
|
|
162 writing it). Whether that is true depends on what the Library does
|
|
|
163 and what the program that uses the Library does.
|
|
|
164
|
|
|
165 1. You may copy and distribute verbatim copies of the Library's
|
|
|
166 complete source code as you receive it, in any medium, provided that
|
|
|
167 you conspicuously and appropriately publish on each copy an
|
|
|
168 appropriate copyright notice and disclaimer of warranty; keep intact
|
|
|
169 all the notices that refer to this License and to the absence of any
|
|
|
170 warranty; and distribute a copy of this License along with the
|
|
|
171 Library.
|
|
|
172
|
|
|
173 You may charge a fee for the physical act of transferring a copy,
|
|
|
174 and you may at your option offer warranty protection in exchange for a
|
|
|
175 fee.
|
|
|
176
|
|
|
177 2. You may modify your copy or copies of the Library or any portion
|
|
|
178 of it, thus forming a work based on the Library, and copy and
|
|
|
179 distribute such modifications or work under the terms of Section 1
|
|
|
180 above, provided that you also meet all of these conditions:
|
|
|
181
|
|
|
182 a) The modified work must itself be a software library.
|
|
|
183
|
|
|
184 b) You must cause the files modified to carry prominent notices
|
|
|
185 stating that you changed the files and the date of any change.
|
|
|
186
|
|
|
187 c) You must cause the whole of the work to be licensed at no
|
|
|
188 charge to all third parties under the terms of this License.
|
|
|
189
|
|
|
190 d) If a facility in the modified Library refers to a function or a
|
|
|
191 table of data to be supplied by an application program that uses
|
|
|
192 the facility, other than as an argument passed when the facility
|
|
|
193 is invoked, then you must make a good faith effort to ensure that,
|
|
|
194 in the event an application does not supply such function or
|
|
|
195 table, the facility still operates, and performs whatever part of
|
|
|
196 its purpose remains meaningful.
|
|
|
197
|
|
|
198 (For example, a function in a library to compute square roots has
|
|
|
199 a purpose that is entirely well-defined independent of the
|
|
|
200 application. Therefore, Subsection 2d requires that any
|
|
|
201 application-supplied function or table used by this function must
|
|
|
202 be optional: if the application does not supply it, the square
|
|
|
203 root function must still compute square roots.)
|
|
|
204
|
|
|
205 These requirements apply to the modified work as a whole. If
|
|
|
206 identifiable sections of that work are not derived from the Library,
|
|
|
207 and can be reasonably considered independent and separate works in
|
|
|
208 themselves, then this License, and its terms, do not apply to those
|
|
|
209 sections when you distribute them as separate works. But when you
|
|
|
210 distribute the same sections as part of a whole which is a work based
|
|
|
211 on the Library, the distribution of the whole must be on the terms of
|
|
|
212 this License, whose permissions for other licensees extend to the
|
|
|
213 entire whole, and thus to each and every part regardless of who wrote
|
|
|
214 it.
|
|
|
215
|
|
|
216 Thus, it is not the intent of this section to claim rights or contest
|
|
|
217 your rights to work written entirely by you; rather, the intent is to
|
|
|
218 exercise the right to control the distribution of derivative or
|
|
|
219 collective works based on the Library.
|
|
|
220
|
|
|
221 In addition, mere aggregation of another work not based on the Library
|
|
|
222 with the Library (or with a work based on the Library) on a volume of
|
|
|
223 a storage or distribution medium does not bring the other work under
|
|
|
224 the scope of this License.
|
|
|
225
|
|
|
226 3. You may opt to apply the terms of the ordinary GNU General Public
|
|
|
227 License instead of this License to a given copy of the Library. To do
|
|
|
228 this, you must alter all the notices that refer to this License, so
|
|
|
229 that they refer to the ordinary GNU General Public License, version 2,
|
|
|
230 instead of to this License. (If a newer version than version 2 of the
|
|
|
231 ordinary GNU General Public License has appeared, then you can specify
|
|
|
232 that version instead if you wish.) Do not make any other change in
|
|
|
233 these notices.
|
|
|
234
|
|
|
235 Once this change is made in a given copy, it is irreversible for
|
|
|
236 that copy, so the ordinary GNU General Public License applies to all
|
|
|
237 subsequent copies and derivative works made from that copy.
|
|
|
238
|
|
|
239 This option is useful when you wish to copy part of the code of
|
|
|
240 the Library into a program that is not a library.
|
|
|
241
|
|
|
242 4. 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 5. A program that contains no derivative of any portion of the
|
|
|
256 Library, but is designed to work with the Library by being compiled or
|
|
|
257 linked with it, is called a "work that uses the Library". Such a
|
|
|
258 work, in isolation, is not a derivative work of the Library, and
|
|
|
259 therefore falls outside the scope of this License.
|
|
|
260
|
|
|
261 However, linking a "work that uses the Library" with the Library
|
|
|
262 creates an executable that is a derivative of the Library (because it
|
|
|
263 contains portions of the Library), rather than a "work that uses the
|
|
|
264 library". The executable is therefore covered by this License.
|
|
|
265 Section 6 states terms for distribution of such executables.
|
|
|
266
|
|
|
267 When a "work that uses the Library" uses material from a header file
|
|
|
268 that is part of the Library, the object code for the work may be a
|
|
|
269 derivative work of the Library even though the source code is not.
|
|
|
270 Whether this is true is especially significant if the work can be
|
|
|
271 linked without the Library, or if the work is itself a library. The
|
|
|
272 threshold for this to be true is not precisely defined by law.
|
|
|
273
|
|
|
274 If such an object file uses only numerical parameters, data
|
|
|
275 structure layouts and accessors, and small macros and small inline
|
|
|
276 functions (ten lines or less in length), then the use of the object
|
|
|
277 file is unrestricted, regardless of whether it is legally a derivative
|
|
|
278 work. (Executables containing this object code plus portions of the
|
|
|
279 Library will still fall under Section 6.)
|
|
|
280
|
|
|
281 Otherwise, if the work is a derivative of the Library, you may
|
|
|
282 distribute the object code for the work under the terms of Section 6.
|
|
|
283 Any executables containing that work also fall under Section 6,
|
|
|
284 whether or not they are linked directly with the Library itself.
|
|
|
285
|
|
|
286 6. As an exception to the Sections above, you may also combine or
|
|
|
287 link a "work that uses the Library" with the Library to produce a
|
|
|
288 work containing portions of the Library, and distribute that work
|
|
|
289 under terms of your choice, provided that the terms permit
|
|
|
290 modification of the work for the customer's own use and reverse
|
|
|
291 engineering for debugging such modifications.
|
|
|
292
|
|
|
293 You must give prominent notice with each copy of the work that the
|
|
|
294 Library is used in it and that the Library and its use are covered by
|
|
|
295 this License. You must supply a copy of this License. If the work
|
|
|
296 during execution displays copyright notices, you must include the
|
|
|
297 copyright notice for the Library among them, as well as a reference
|
|
|
298 directing the user to the copy of this License. Also, you must do one
|
|
|
299 of these things:
|
|
|
300
|
|
|
301 a) Accompany the work with the complete corresponding
|
|
|
302 machine-readable source code for the Library including whatever
|
|
|
303 changes were used in the work (which must be distributed under
|
|
|
304 Sections 1 and 2 above); and, if the work is an executable linked
|
|
|
305 with the Library, with the complete machine-readable "work that
|
|
|
306 uses the Library", as object code and/or source code, so that the
|
|
|
307 user can modify the Library and then relink to produce a modified
|
|
|
308 executable containing the modified Library. (It is understood
|
|
|
309 that the user who changes the contents of definitions files in the
|
|
|
310 Library will not necessarily be able to recompile the application
|
|
|
311 to use the modified definitions.)
|
|
|
312
|
|
|
313 b) Use a suitable shared library mechanism for linking with the
|
|
|
314 Library. A suitable mechanism is one that (1) uses at run time a
|
|
|
315 copy of the library already present on the user's computer system,
|
|
|
316 rather than copying library functions into the executable, and (2)
|
|
|
317 will operate properly with a modified version of the library, if
|
|
|
318 the user installs one, as long as the modified version is
|
|
|
319 interface-compatible with the version that the work was made with.
|
|
|
320
|
|
|
321 c) Accompany the work with a written offer, valid for at
|
|
|
322 least three years, to give the same user the materials
|
|
|
323 specified in Subsection 6a, above, for a charge no more
|
|
|
324 than the cost of performing this distribution.
|
|
|
325
|
|
|
326 d) If distribution of the work is made by offering access to copy
|
|
|
327 from a designated place, offer equivalent access to copy the above
|
|
|
328 specified materials from the same place.
|
|

|
330 e) Verify that the user has already received a copy of these
|
|
|
331 materials or that you have already sent this user a copy.
|
|
|
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 materials to be distributed need not include anything that is
|
|
|
337 normally 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 7. You may place library facilities that are a work based on the
|
|
|
349 Library side-by-side in a single library together with other library
|
|
|
350 facilities not covered by this License, and distribute such a combined
|
|
|
351 library, provided that the separate distribution of the work based on
|
|
|
352 the Library and of the other library facilities is otherwise
|
|
|
353 permitted, and provided that you do these two things:
|
|
|
354
|
|
|
355 a) Accompany the combined library with a copy of the same work
|
|
|
356 based on the Library, uncombined with any other library
|
|
|
357 facilities. This must be distributed under the terms of the
|
|
|
358 Sections above.
|
|
|
359
|
|
|
360 b) Give prominent notice with the combined library of the fact
|
|
|
361 that part of it is a work based on the Library, and explaining
|
|
|
362 where to find the accompanying uncombined form of the same work.
|
|
|
363
|
|
|
364 8. You may not copy, modify, sublicense, link with, or distribute
|
|
|
365 the Library except as expressly provided under this License. Any
|
|
|
366 attempt otherwise to copy, modify, sublicense, link with, or
|
|
|
367 distribute the Library is void, and will automatically terminate your
|
|
|
368 rights under this License. However, parties who have received copies,
|
|
|
369 or rights, from you under this License will not have their licenses
|
|
|
370 terminated so long as such parties remain in full compliance.
|
|
|
371
|
|
|
372 9. You are not required to accept this License, since you have not
|
|
|
373 signed it. However, nothing else grants you permission to modify or
|
|
|
374 distribute the Library or its derivative works. These actions are
|
|
|
375 prohibited by law if you do not accept this License. Therefore, by
|
|
|
376 modifying or distributing the Library (or any work based on the
|
|
|
377 Library), you indicate your acceptance of this License to do so, and
|
|
|
378 all its terms and conditions for copying, distributing or modifying
|
|
|
379 the Library or works based on it.
|
|
|
380
|
|
|
381 10. Each time you redistribute the Library (or any work based on the
|
|
|
382 Library), the recipient automatically receives a license from the
|
|
|
383 original licensor to copy, distribute, link with or modify the Library
|
|
|
384 subject to these terms and conditions. You may not impose any further
|
|
|
385 restrictions on the recipients' exercise of the rights granted herein.
|
|
|
386 You are not responsible for enforcing compliance by third parties with
|
|
|
387 this License.
|
|
|
388
|
|
|
389 11. If, as a consequence of a court judgment or allegation of patent
|
|
|
390 infringement or for any other reason (not limited to patent issues),
|
|
|
391 conditions are imposed on you (whether by court order, agreement or
|
|
|
392 otherwise) that contradict the conditions of this License, they do not
|
|
|
393 excuse you from the conditions of this License. If you cannot
|
|
|
394 distribute so as to satisfy simultaneously your obligations under this
|
|
|
395 License and any other pertinent obligations, then as a consequence you
|
|
|
396 may not distribute the Library at all. For example, if a patent
|
|
|
397 license would not permit royalty-free redistribution of the Library by
|
|
|
398 all those who receive copies directly or indirectly through you, then
|
|
|
399 the only way you could satisfy both it and this License would be to
|
|
|
400 refrain entirely from distribution of the Library.
|
|
|
401
|
|
|
402 If any portion of this section is held invalid or unenforceable under any
|
|
|
403 particular circumstance, the balance of the section is intended to apply,
|
|
|
404 and the section as a whole is intended to apply in other circumstances.
|
|
|
405
|
|
|
406 It is not the purpose of this section to induce you to infringe any
|
|
|
407 patents or other property right claims or to contest validity of any
|
|
|
408 such claims; this section has the sole purpose of protecting the
|
|
|
409 integrity of the free software distribution system which is
|
|
|
410 implemented by public license practices. Many people have made
|
|
|
411 generous contributions to the wide range of software distributed
|
|
|
412 through that system in reliance on consistent application of that
|
|
|
413 system; it is up to the author/donor to decide if he or she is willing
|
|
|
414 to distribute software through any other system and a licensee cannot
|
|
|
415 impose that choice.
|
|
|
416
|
|
|
417 This section is intended to make thoroughly clear what is believed to
|
|
|
418 be a consequence of the rest of this License.
|
|
|
419
|
|
|
420 12. If the distribution and/or use of the Library is restricted in
|
|
|
421 certain countries either by patents or by copyrighted interfaces, the
|
|
|
422 original copyright holder who places the Library under this License may add
|
|
|
423 an explicit geographical distribution limitation excluding those countries,
|
|
|
424 so that distribution is permitted only in or among countries not thus
|
|
|
425 excluded. In such case, this License incorporates the limitation as if
|
|
|
426 written in the body of this License.
|
|
|
427
|
|
|
428 13. The Free Software Foundation may publish revised and/or new
|
|
|
429 versions of the Lesser General Public License from time to time.
|
|
|
430 Such new versions will be similar in spirit to the present version,
|
|
|
431 but may differ in detail to address new problems or concerns.
|
|
|
432
|
|
|
433 Each version is given a distinguishing version number. If the Library
|
|
|
434 specifies a version number of this License which applies to it and
|
|
|
435 "any later version", you have the option of following the terms and
|
|
|
436 conditions either of that version or of any later version published by
|
|
|
437 the Free Software Foundation. If the Library does not specify a
|
|
|
438 license version number, you may choose any version ever published by
|
|
|
439 the Free Software Foundation.
|
|
|
440
|
|
|
441 14. If you wish to incorporate parts of the Library into other free
|
|
|
442 programs whose distribution conditions are incompatible with these,
|
|
|
443 write to the author to ask for permission. For software which is
|
|
|
444 copyrighted by the Free Software Foundation, write to the Free
|
|
|
445 Software Foundation; we sometimes make exceptions for this. Our
|
|
|
446 decision will be guided by the two goals of preserving the free status
|
|
|
447 of all derivatives of our free software and of promoting the sharing
|
|
|
448 and reuse of software generally.
|
|
|
449
|
|
|
450 NO WARRANTY
|
|
|
451
|
|
|
452 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
|
453 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
|
454 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
|
455 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
|
|
456 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
|
|
457 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
|
458 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
|
|
459 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
|
460 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
|
461
|
|
|
462 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
|
463 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
|
464 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
|
|
465 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
|
|
466 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
|
|
467 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
|
|
468 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
|
|
469 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
|
|
470 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
|
|
471 DAMAGES.

475 How to Apply These Terms to Your New Libraries
|
|
|
476
|
|
|
477 If you develop a new library, and you want it to be of the greatest
|
|
|
478 possible use to the public, we recommend making it free software that
|
|
|
479 everyone can redistribute and change. You can do so by permitting
|
|
|
480 redistribution under these terms (or, alternatively, under the terms of the
|
|
|
481 ordinary General Public License).
|
|
|
482
|
|
|
483 To apply these terms, attach the following notices to the library. It is
|
|
|
484 safest to attach them to the start of each source file to most effectively
|
|
|
485 convey the exclusion of warranty; and each file should have at least the
|
|
|
486 "copyright" line and a pointer to where the full notice is found.
|
|
|
487
|
|
|
488 <one line to give the library's name and a brief idea of what it does.>

507 You should also get your employer (if you work as a programmer) or your

509 necessary. Here is a sample; alter the names:
