7 Everyone is permitted to copy and distribute verbatim copies

10[This is the first released version of the Lesser GPL. It also counts
11 as the successor of the GNU Library Public License, version 2, hence
12 the version number 2.1.]
13
14 Preamble
15
16 The licenses for most software are designed to take away your
17freedom to share and change it. By contrast, the GNU General Public
18Licenses are intended to guarantee your freedom to share and change
19free software--to make sure the software is free for all its users.
20
21 This license, the Lesser General Public License, applies to some
22specially designated software packages--typically libraries--of the
23Free Software Foundation and other authors who decide to use it. You
24can use it too, but we suggest you first think carefully about whether
25this license or the ordinary General Public License is the better
26strategy to use in any particular case, based on the explanations
27below.
28
29 When we speak of free software, we are referring to freedom of use,
30not price. Our General Public Licenses are designed to make sure that
31you have the freedom to distribute copies of free software (and charge
32for this service if you wish); that you receive source code or can get
33it if you want it; that you can change the software and use pieces of
34it in new free programs; and that you are informed that you can do
35these things.
36
37 To protect your rights, we need to make restrictions that forbid
38distributors to deny you these rights or to ask you to surrender these
39rights. These restrictions translate to certain responsibilities for
40you if you distribute copies of the library or if you modify it.
41
42 For example, if you distribute copies of the library, whether gratis
43or for a fee, you must give the recipients all the rights that we gave
44you. You must make sure that they, too, receive or can get the source
45code. If you link other code with the library, you must provide
46complete object files to the recipients, so that they can relink them
47with the library after making changes to the library and recompiling
48it. And you must show them these terms so they know their rights.
49
50 We protect your rights with a two-step method: (1) we copyright the
51library, and (2) we offer you this license, which gives you legal
52permission to copy, distribute and/or modify the library.
53
54 To protect each distributor, we want to make it very clear that
55there is no warranty for the free library. Also, if the library is
56modified by someone else and passed on, the recipients should know
57that what they have is not the original version, so that the original
58author's reputation will not be affected by problems that might be
59introduced by others.
60^L
61 Finally, software patents pose a constant threat to the existence of
62any free program. We wish to make sure that a company cannot
63effectively restrict the users of a free program by obtaining a
64restrictive license from a patent holder. Therefore, we insist that
65any patent license obtained for a version of the library must be
66consistent with the full freedom of use specified in this license.
67
68 Most GNU software, including some libraries, is covered by the
69ordinary GNU General Public License. This license, the GNU Lesser
70General Public License, applies to certain designated libraries, and
71is quite different from the ordinary General Public License. We use
72this license for certain libraries in order to permit linking those
73libraries into non-free programs.
74
75 When a program is linked with a library, whether statically or using
76a shared library, the combination of the two is legally speaking a
77combined work, a derivative of the original library. The ordinary
78General Public License therefore permits such linking only if the
79entire combination fits its criteria of freedom. The Lesser General
80Public License permits more lax criteria for linking other code with
81the library.
82
83 We call this license the "Lesser" General Public License because it
84does Less to protect the user's freedom than the ordinary General
85Public License. It also provides other free software developers Less
86of an advantage over competing non-free programs. These disadvantages
87are the reason we use the ordinary General Public License for many
88libraries. However, the Lesser license provides advantages in certain
89special circumstances.
90
91 For example, on rare occasions, there may be a special need to
92encourage the widest possible use of a certain library, so that it
93becomes a de-facto standard. To achieve this, non-free programs must
94be allowed to use the library. A more frequent case is that a free
95library does the same job as widely used non-free libraries. In this
96case, there is little to gain by limiting the free library to free
97software only, so we use the Lesser General Public License.
98
99 In other cases, permission to use a particular library in non-free
100programs enables a greater number of people to use a large body of
101free software. For example, permission to use the GNU C Library in
102non-free programs enables many more people to use the whole GNU
103operating system, as well as its variant, the GNU/Linux operating
104system.
105
106 Although the Lesser General Public License is Less protective of the
107users' freedom, it does ensure that the user of a program that is
108linked with the Library has the freedom and the wherewithal to run
109that program using a modified version of the Library.
110
111 The precise terms and conditions for copying, distribution and
112modification follow. Pay close attention to the difference between a
113"work based on the library" and a "work that uses the library". The
114former contains code derived from the library, whereas the latter must
115be combined with the library in order to run.
116^L
117 GNU LESSER GENERAL PUBLIC LICENSE
118 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119
120 0. This License Agreement applies to any software library or other
121program which contains a notice placed by the copyright holder or
122other authorized party saying it may be distributed under the terms of
123this Lesser General Public License (also called "this License").
124Each licensee is addressed as "you".
125
126 A "library" means a collection of software functions and/or data
127prepared 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
131which has been distributed under these terms. A "work based on the
132Library" means either the Library or any derivative work under
133copyright law: that is to say, a work containing the Library or a
134portion of it, either verbatim or with modifications and/or translated
135straightforwardly into another language. (Hereinafter, translation is
136included without limitation in the term "modification".)
137
138 "Source code" for a work means the preferred form of the work for
139making modifications to it. For a library, complete source code means
140all the source code for all modules it contains, plus any associated
141interface definition files, plus the scripts used to control
142compilation and installation of the library.
143
144 Activities other than copying, distribution and modification are not
145covered by this License; they are outside its scope. The act of
146running a program using the Library is not restricted, and output from
147such a program is covered only if its contents constitute a work based
148on the Library (independent of the use of the Library in a tool for
149writing it). Whether that is true depends on what the Library does
150and what the program that uses the Library does.
151
152 1. You may copy and distribute verbatim copies of the Library's
153complete source code as you receive it, in any medium, provided that
154you conspicuously and appropriately publish on each copy an
155appropriate copyright notice and disclaimer of warranty; keep intact
156all the notices that refer to this License and to the absence of any
157warranty; and distribute a copy of this License along with the
158Library.
159
160 You may charge a fee for the physical act of transferring a copy,
161and you may at your option offer warranty protection in exchange for a
162fee.
163
164
165 2. You may modify your copy or copies of the Library or any portion
166of it, thus forming a work based on the Library, and copy and
167distribute such modifications or work under the terms of Section 1
168above, provided that you also meet all of these conditions:
169
170 a) The modified work must itself be a software library.
171
172 b) You must cause the files modified to carry prominent notices
173 stating that you changed the files and the date of any change.
174
175 c) You must cause the whole of the work to be licensed at no
176 charge to all third parties under the terms of this License.
177
178 d) If a facility in the modified Library refers to a function or a
179 table of data to be supplied by an application program that uses
180 the facility, other than as an argument passed when the facility
181 is invoked, then you must make a good faith effort to ensure that,
182 in the event an application does not supply such function or
183 table, the facility still operates, and performs whatever part of
184 its purpose remains meaningful.
185
186 (For example, a function in a library to compute square roots has
187 a purpose that is entirely well-defined independent of the
188 application. Therefore, Subsection 2d requires that any
189 application-supplied function or table used by this function must
190 be optional: if the application does not supply it, the square
191 root function must still compute square roots.)
192
193These requirements apply to the modified work as a whole. If
194identifiable sections of that work are not derived from the Library,
195and can be reasonably considered independent and separate works in
196themselves, then this License, and its terms, do not apply to those
197sections when you distribute them as separate works. But when you
198distribute the same sections as part of a whole which is a work based
199on the Library, the distribution of the whole must be on the terms of
200this License, whose permissions for other licensees extend to the
201entire whole, and thus to each and every part regardless of who wrote
202it.
203
204Thus, it is not the intent of this section to claim rights or contest
205your rights to work written entirely by you; rather, the intent is to
206exercise the right to control the distribution of derivative or
207collective works based on the Library.
208
209In addition, mere aggregation of another work not based on the Library
210with the Library (or with a work based on the Library) on a volume of
211a storage or distribution medium does not bring the other work under
212the scope of this License.
213
214 3. You may opt to apply the terms of the ordinary GNU General Public
215License instead of this License to a given copy of the Library. To do
216this, you must alter all the notices that refer to this License, so
217that they refer to the ordinary GNU General Public License, version 2,
218instead of to this License. (If a newer version than version 2 of the
219ordinary GNU General Public License has appeared, then you can specify
220that version instead if you wish.) Do not make any other change in
221these notices.
222^L
223 Once this change is made in a given copy, it is irreversible for
224that copy, so the ordinary GNU General Public License applies to all
225subsequent copies and derivative works made from that copy.
226
227 This option is useful when you wish to copy part of the code of
228the Library into a program that is not a library.
229
230 4. You may copy and distribute the Library (or a portion or
231derivative of it, under Section 2) in object code or executable form
232under the terms of Sections 1 and 2 above provided that you accompany
233it with the complete corresponding machine-readable source code, which
234must be distributed under the terms of Sections 1 and 2 above on a
235medium customarily used for software interchange.
236
237 If distribution of object code is made by offering access to copy
238from a designated place, then offering equivalent access to copy the
239source code from the same place satisfies the requirement to
240distribute the source code, even though third parties are not
241compelled to copy the source along with the object code.
242
243 5. A program that contains no derivative of any portion of the
244Library, but is designed to work with the Library by being compiled or
245linked with it, is called a "work that uses the Library". Such a
246work, in isolation, is not a derivative work of the Library, and
247therefore falls outside the scope of this License.
248
249 However, linking a "work that uses the Library" with the Library
250creates an executable that is a derivative of the Library (because it
251contains portions of the Library), rather than a "work that uses the
252library". The executable is therefore covered by this License.
253Section 6 states terms for distribution of such executables.
254
255 When a "work that uses the Library" uses material from a header file
256that is part of the Library, the object code for the work may be a
257derivative work of the Library even though the source code is not.
258Whether this is true is especially significant if the work can be
259linked without the Library, or if the work is itself a library. The
260threshold for this to be true is not precisely defined by law.
261
262 If such an object file uses only numerical parameters, data
263structure layouts and accessors, and small macros and small inline
264functions (ten lines or less in length), then the use of the object
265file is unrestricted, regardless of whether it is legally a derivative
266work. (Executables containing this object code plus portions of the
267Library will still fall under Section 6.)
268
269 Otherwise, if the work is a derivative of the Library, you may
270distribute the object code for the work under the terms of Section 6.
271Any executables containing that work also fall under Section 6,
272whether or not they are linked directly with the Library itself.
273^L
274 6. As an exception to the Sections above, you may also combine or
275link a "work that uses the Library" with the Library to produce a
276work containing portions of the Library, and distribute that work
277under terms of your choice, provided that the terms permit
278modification of the work for the customer's own use and reverse
279engineering for debugging such modifications.
280
281 You must give prominent notice with each copy of the work that the
282Library is used in it and that the Library and its use are covered by
283this License. You must supply a copy of this License. If the work
284during execution displays copyright notices, you must include the
285copyright notice for the Library among them, as well as a reference
286directing the user to the copy of this License. Also, you must do one
287of these things:
288
289 a) Accompany the work with the complete corresponding
290 machine-readable source code for the Library including whatever
291 changes were used in the work (which must be distributed under
292 Sections 1 and 2 above); and, if the work is an executable linked
293 with the Library, with the complete machine-readable "work that
294 uses the Library", as object code and/or source code, so that the
295 user can modify the Library and then relink to produce a modified
296 executable containing the modified Library. (It is understood
297 that the user who changes the contents of definitions files in the
298 Library will not necessarily be able to recompile the application
299 to use the modified definitions.)
300
301 b) Use a suitable shared library mechanism for linking with the
302 Library. A suitable mechanism is one that (1) uses at run time a
303 copy of the library already present on the user's computer system,
304 rather than copying library functions into the executable, and (2)
305 will operate properly with a modified version of the library, if
306 the user installs one, as long as the modified version is
307 interface-compatible with the version that the work was made with.
308
309 c) Accompany the work with a written offer, valid for at least
310 three years, to give the same user the materials specified in
311 Subsection 6a, above, for a charge no more than the cost of
312 performing this distribution.
313
314 d) If distribution of the work is made by offering access to copy
315 from a designated place, offer equivalent access to copy the above
316 specified materials from the same place.
317
318 e) Verify that the user has already received a copy of these
319 materials or that you have already sent this user a copy.
320
321 For an executable, the required form of the "work that uses the
322Library" must include any data and utility programs needed for
323reproducing the executable from it. However, as a special exception,
324the materials to be distributed need not include anything that is
325normally distributed (in either source or binary form) with the major
326components (compiler, kernel, and so on) of the operating system on
327which the executable runs, unless that component itself accompanies
328the executable.
329
330 It may happen that this requirement contradicts the license
331restrictions of other proprietary libraries that do not normally
332accompany the operating system. Such a contradiction means you cannot
333use both them and the Library together in an executable that you
334distribute.
335^L
336 7. You may place library facilities that are a work based on the
337Library side-by-side in a single library together with other library
338facilities not covered by this License, and distribute such a combined
339library, provided that the separate distribution of the work based on
340the Library and of the other library facilities is otherwise
341permitted, and provided that you do these two things:
342
343 a) Accompany the combined library with a copy of the same work
344 based on the Library, uncombined with any other library
345 facilities. This must be distributed under the terms of the
346 Sections above.
347
348 b) Give prominent notice with the combined library of the fact
349 that part of it is a work based on the Library, and explaining
350 where to find the accompanying uncombined form of the same work.
351
352 8. You may not copy, modify, sublicense, link with, or distribute
353the Library except as expressly provided under this License. Any
354attempt otherwise to copy, modify, sublicense, link with, or
355distribute the Library is void, and will automatically terminate your
356rights under this License. However, parties who have received copies,
357or rights, from you under this License will not have their licenses
358terminated so long as such parties remain in full compliance.
359
360 9. You are not required to accept this License, since you have not
361signed it. However, nothing else grants you permission to modify or
362distribute the Library or its derivative works. These actions are
363prohibited by law if you do not accept this License. Therefore, by
364modifying or distributing the Library (or any work based on the
365Library), you indicate your acceptance of this License to do so, and
366all its terms and conditions for copying, distributing or modifying
367the Library or works based on it.
368
369 10. Each time you redistribute the Library (or any work based on the
370Library), the recipient automatically receives a license from the
371original licensor to copy, distribute, link with or modify the Library
372subject to these terms and conditions. You may not impose any further
373restrictions on the recipients' exercise of the rights granted herein.
374You are not responsible for enforcing compliance by third parties with
375this License.
376^L
377 11. If, as a consequence of a court judgment or allegation of patent
378infringement or for any other reason (not limited to patent issues),
379conditions are imposed on you (whether by court order, agreement or
380otherwise) that contradict the conditions of this License, they do not
381excuse you from the conditions of this License. If you cannot
382distribute so as to satisfy simultaneously your obligations under this
383License and any other pertinent obligations, then as a consequence you
384may not distribute the Library at all. For example, if a patent
385license would not permit royalty-free redistribution of the Library by
386all those who receive copies directly or indirectly through you, then
387the only way you could satisfy both it and this License would be to
388refrain entirely from distribution of the Library.
389
390If any portion of this section is held invalid or unenforceable under
391any particular circumstance, the balance of the section is intended to
392apply, and the section as a whole is intended to apply in other
393circumstances.
394
395It is not the purpose of this section to induce you to infringe any
396patents or other property right claims or to contest validity of any
397such claims; this section has the sole purpose of protecting the
398integrity of the free software distribution system which is
399implemented by public license practices. Many people have made
400generous contributions to the wide range of software distributed
401through that system in reliance on consistent application of that
402system; it is up to the author/donor to decide if he or she is willing
403to distribute software through any other system and a licensee cannot
404impose that choice.
405
406This section is intended to make thoroughly clear what is believed to
407be a consequence of the rest of this License.
408
409 12. If the distribution and/or use of the Library is restricted in
410certain countries either by patents or by copyrighted interfaces, the
411original copyright holder who places the Library under this License
412may add an explicit geographical distribution limitation excluding those
413countries, so that distribution is permitted only in or among
414countries not thus excluded. In such case, this License incorporates
415the limitation as if written in the body of this License.
416
417 13. The Free Software Foundation may publish revised and/or new
418versions of the Lesser General Public License from time to time.
419Such new versions will be similar in spirit to the present version,
420but may differ in detail to address new problems or concerns.
421
422Each version is given a distinguishing version number. If the Library
423specifies a version number of this License which applies to it and
424"any later version", you have the option of following the terms and
425conditions either of that version or of any later version published by
426the Free Software Foundation. If the Library does not specify a
427license version number, you may choose any version ever published by
428the Free Software Foundation.
429^L
430 14. If you wish to incorporate parts of the Library into other free
431programs whose distribution conditions are incompatible with these,
432write to the author to ask for permission. For software which is
433copyrighted by the Free Software Foundation, write to the Free
434Software Foundation; we sometimes make exceptions for this. Our
435decision will be guided by the two goals of preserving the free status
436of all derivatives of our free software and of promoting the sharing
437and reuse of software generally.
438
439 NO WARRANTY
440
441 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
442WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
443EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
444OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
445KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
446IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
447PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
448LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
449THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
450
451 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
452WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
453AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
454FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
455CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
456LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
457RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
458FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
459SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
460DAMAGES.
