5 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
6 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
7 Everyone is permitted to copy and distribute verbatim copies
8 of this license document, but changing it is not allowed.

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 below.
27
28  When we speak of free software, we are referring to freedom of use,
29not price.  Our General Public Licenses are designed to make sure that
30you have the freedom to distribute copies of free software (and charge
31for this service if you wish); that you receive source code or can get
32it if you want it; that you can change the software and use pieces of
33it in new free programs; and that you are informed that you can do
34these things.
35
36  To protect your rights, we need to make restrictions that forbid
37distributors to deny you these rights or to ask you to surrender these
38rights.  These restrictions translate to certain responsibilities for
39you if you distribute copies of the library or if you modify it.
40
41  For example, if you distribute copies of the library, whether gratis
42or for a fee, you must give the recipients all the rights that we gave
43you.  You must make sure that they, too, receive or can get the source
44code.  If you link other code with the library, you must provide
45complete object files to the recipients, so that they can relink them
46with the library after making changes to the library and recompiling
47it.  And you must show them these terms so they know their rights.
48
49  We protect your rights with a two-step method: (1) we copyright the
50library, and (2) we offer you this license, which gives you legal
51permission to copy, distribute and/or modify the library.
52
53  To protect each distributor, we want to make it very clear that
54there is no warranty for the free library.  Also, if the library is
55modified by someone else and passed on, the recipients should know
56that what they have is not the original version, so that the original
57author's reputation will not be affected by problems that might be
58introduced by others.
59
60  Finally, software patents pose a constant threat to the existence of
61any free program.  We wish to make sure that a company cannot
62effectively restrict the users of a free program by obtaining a
63restrictive license from a patent holder.  Therefore, we insist that
64any patent license obtained for a version of the library must be
65consistent with the full freedom of use specified in this license.
66
67  Most GNU software, including some libraries, is covered by the
68ordinary GNU General Public License.  This license, the GNU Lesser
69General Public License, applies to certain designated libraries, and
70is quite different from the ordinary General Public License.  We use
71this license for certain libraries in order to permit linking those
72libraries into non-free programs.
73
74  When a program is linked with a library, whether statically or using
75a shared library, the combination of the two is legally speaking a
76combined work, a derivative of the original library.  The ordinary
77General Public License therefore permits such linking only if the
78entire combination fits its criteria of freedom.  The Lesser General
79Public License permits more lax criteria for linking other code with
80the library.
81
82  We call this license the "Lesser" General Public License because it
83does Less to protect the user's freedom than the ordinary General
84Public License.  It also provides other free software developers Less
85of an advantage over competing non-free programs.  These disadvantages
86are the reason we use the ordinary General Public License for many
87libraries.  However, the Lesser license provides advantages in certain
88special circumstances.
89
90  For example, on rare occasions, there may be a special need to
91encourage the widest possible use of a certain library, so that it becomes
92a de-facto standard.  To achieve this, non-free programs must be
93allowed to use the library.  A more frequent case is that a free
94library does the same job as widely used non-free libraries.  In this
95case, there is little to gain by limiting the free library to free
96software only, so we use the Lesser General Public License.
97
98  In other cases, permission to use a particular library in non-free
99programs enables a greater number of people to use a large body of
100free software.  For example, permission to use the GNU C Library in
101non-free programs enables many more people to use the whole GNU
102operating system, as well as its variant, the GNU/Linux operating
103system.
104
105  Although the Lesser General Public License is Less protective of the
106users' freedom, it does ensure that the user of a program that is
107linked with the Library has the freedom and the wherewithal to run
108that program using a modified version of the Library.
109
110  The precise terms and conditions for copying, distribution and
111modification follow.  Pay close attention to the difference between a
112"work based on the library" and a "work that uses the library".  The
113former contains code derived from the library, whereas the latter must
114be combined with the library in order to run.
115
116                  GNU LESSER GENERAL PUBLIC LICENSE
117   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
118
119  0. This License Agreement applies to any software library or other
120program which contains a notice placed by the copyright holder or
121other authorized party saying it may be distributed under the terms of
122this Lesser General Public License (also called "this License").
123Each licensee is addressed as "you".
124
125  A "library" means a collection of software functions and/or data
126prepared so as to be conveniently linked with application programs
127(which use some of those functions and data) to form executables.
128
129  The "Library", below, refers to any such software library or work
130which has been distributed under these terms.  A "work based on the
131Library" means either the Library or any derivative work under
132copyright law: that is to say, a work containing the Library or a
133portion of it, either verbatim or with modifications and/or translated
134straightforwardly into another language.  (Hereinafter, translation is
135included without limitation in the term "modification".)
136
137  "Source code" for a work means the preferred form of the work for
138making modifications to it.  For a library, complete source code means
139all the source code for all modules it contains, plus any associated
140interface definition files, plus the scripts used to control compilation
141and installation of the library.
142
143  Activities other than copying, distribution and modification are not
144covered by this License; they are outside its scope.  The act of
145running a program using the Library is not restricted, and output from
146such a program is covered only if its contents constitute a work based
147on the Library (independent of the use of the Library in a tool for
148writing it).  Whether that is true depends on what the Library does
149and what the program that uses the Library does.
150 
151  1. You may copy and distribute verbatim copies of the Library's
152complete source code as you receive it, in any medium, provided that
153you conspicuously and appropriately publish on each copy an
154appropriate copyright notice and disclaimer of warranty; keep intact
155all the notices that refer to this License and to the absence of any
156warranty; and distribute a copy of this License along with the
157Library.
158
159  You may charge a fee for the physical act of transferring a copy,
160and you may at your option offer warranty protection in exchange for a
161fee.
162
163  2. You may modify your copy or copies of the Library or any portion
164of it, thus forming a work based on the Library, and copy and
165distribute such modifications or work under the terms of Section 1
166above, provided that you also meet all of these conditions:
167
168    a) The modified work must itself be a software library.
169
170    b) You must cause the files modified to carry prominent notices
171    stating that you changed the files and the date of any change.
172
173    c) You must cause the whole of the work to be licensed at no
174    charge to all third parties under the terms of this License.
175
176    d) If a facility in the modified Library refers to a function or a
177    table of data to be supplied by an application program that uses
178    the facility, other than as an argument passed when the facility
179    is invoked, then you must make a good faith effort to ensure that,
180    in the event an application does not supply such function or
181    table, the facility still operates, and performs whatever part of
182    its purpose remains meaningful.
183
184    (For example, a function in a library to compute square roots has
185    a purpose that is entirely well-defined independent of the
186    application.  Therefore, Subsection 2d requires that any
187    application-supplied function or table used by this function must
188    be optional: if the application does not supply it, the square
189    root function must still compute square roots.)
190
191These requirements apply to the modified work as a whole.  If
192identifiable sections of that work are not derived from the Library,
193and can be reasonably considered independent and separate works in
194themselves, then this License, and its terms, do not apply to those
195sections when you distribute them as separate works.  But when you
196distribute the same sections as part of a whole which is a work based
197on the Library, the distribution of the whole must be on the terms of
198this License, whose permissions for other licensees extend to the
199entire whole, and thus to each and every part regardless of who wrote
200it.
201
202Thus, it is not the intent of this section to claim rights or contest
203your rights to work written entirely by you; rather, the intent is to
204exercise the right to control the distribution of derivative or
205collective works based on the Library.
206
207In addition, mere aggregation of another work not based on the Library
208with the Library (or with a work based on the Library) on a volume of
209a storage or distribution medium does not bring the other work under
210the scope of this License.
211
212  3. You may opt to apply the terms of the ordinary GNU General Public
213License instead of this License to a given copy of the Library.  To do
214this, you must alter all the notices that refer to this License, so
215that they refer to the ordinary GNU General Public License, version 2,
216instead of to this License.  (If a newer version than version 2 of the
217ordinary GNU General Public License has appeared, then you can specify
218that version instead if you wish.)  Do not make any other change in
219these notices.
220
221  Once this change is made in a given copy, it is irreversible for
222that copy, so the ordinary GNU General Public License applies to all
223subsequent copies and derivative works made from that copy.
224
225  This option is useful when you wish to copy part of the code of
226the Library into a program that is not a library.
227
228  4. You may copy and distribute the Library (or a portion or
229derivative of it, under Section 2) in object code or executable form
230under the terms of Sections 1 and 2 above provided that you accompany
231it with the complete corresponding machine-readable source code, which
232must be distributed under the terms of Sections 1 and 2 above on a
233medium customarily used for software interchange.
234
235  If distribution of object code is made by offering access to copy
236from a designated place, then offering equivalent access to copy the
237source code from the same place satisfies the requirement to
238distribute the source code, even though third parties are not
239compelled to copy the source along with the object code.
240
241  5. A program that contains no derivative of any portion of the
242Library, but is designed to work with the Library by being compiled or
243linked with it, is called a "work that uses the Library".  Such a
244work, in isolation, is not a derivative work of the Library, and
245therefore falls outside the scope of this License.
246
247  However, linking a "work that uses the Library" with the Library
248creates an executable that is a derivative of the Library (because it
249contains portions of the Library), rather than a "work that uses the
250library".  The executable is therefore covered by this License.
251Section 6 states terms for distribution of such executables.
252
253  When a "work that uses the Library" uses material from a header file
254that is part of the Library, the object code for the work may be a
255derivative work of the Library even though the source code is not.
256Whether this is true is especially significant if the work can be
257linked without the Library, or if the work is itself a library.  The
258threshold for this to be true is not precisely defined by law.
259
260  If such an object file uses only numerical parameters, data
261structure layouts and accessors, and small macros and small inline
262functions (ten lines or less in length), then the use of the object
263file is unrestricted, regardless of whether it is legally a derivative
264work.  (Executables containing this object code plus portions of the
265Library will still fall under Section 6.)
266
267  Otherwise, if the work is a derivative of the Library, you may
268distribute the object code for the work under the terms of Section 6.
269Any executables containing that work also fall under Section 6,
270whether or not they are linked directly with the Library itself.
271
272  6. As an exception to the Sections above, you may also combine or
273link a "work that uses the Library" with the Library to produce a
274work containing portions of the Library, and distribute that work
275under terms of your choice, provided that the terms permit
276modification of the work for the customer's own use and reverse
277engineering for debugging such modifications.
278
279  You must give prominent notice with each copy of the work that the
280Library is used in it and that the Library and its use are covered by
281this License.  You must supply a copy of this License.  If the work
282during execution displays copyright notices, you must include the
283copyright notice for the Library among them, as well as a reference
284directing the user to the copy of this License.  Also, you must do one
285of these things:
286
287    a) Accompany the work with the complete corresponding
288    machine-readable source code for the Library including whatever
289    changes were used in the work (which must be distributed under
290    Sections 1 and 2 above); and, if the work is an executable linked
291    with the Library, with the complete machine-readable "work that
292    uses the Library", as object code and/or source code, so that the
293    user can modify the Library and then relink to produce a modified
294    executable containing the modified Library.  (It is understood
295    that the user who changes the contents of definitions files in the
296    Library will not necessarily be able to recompile the application
297    to use the modified definitions.)
298
299    b) Use a suitable shared library mechanism for linking with the
300    Library.  A suitable mechanism is one that (1) uses at run time a
301    copy of the library already present on the user's computer system,
302    rather than copying library functions into the executable, and (2)
303    will operate properly with a modified version of the library, if
304    the user installs one, as long as the modified version is
305    interface-compatible with the version that the work was made with.
306
307    c) Accompany the work with a written offer, valid for at
308    least three years, to give the same user the materials
309    specified in Subsection 6a, above, for a charge no more
310    than the cost of performing this distribution.
311
312    d) If distribution of the work is made by offering access to copy
313    from a designated place, offer equivalent access to copy the above
314    specified materials from the same place.
315
316    e) Verify that the user has already received a copy of these
317    materials or that you have already sent this user a copy.
318
319  For an executable, the required form of the "work that uses the
320Library" must include any data and utility programs needed for
321reproducing the executable from it.  However, as a special exception,
322the materials to be distributed need not include anything that is
323normally distributed (in either source or binary form) with the major
324components (compiler, kernel, and so on) of the operating system on
325which the executable runs, unless that component itself accompanies
326the executable.
327
328  It may happen that this requirement contradicts the license
329restrictions of other proprietary libraries that do not normally
330accompany the operating system.  Such a contradiction means you cannot
331use both them and the Library together in an executable that you
332distribute.
333
334  7. You may place library facilities that are a work based on the
335Library side-by-side in a single library together with other library
336facilities not covered by this License, and distribute such a combined
337library, provided that the separate distribution of the work based on
338the Library and of the other library facilities is otherwise
339permitted, and provided that you do these two things:
340
341    a) Accompany the combined library with a copy of the same work
342    based on the Library, uncombined with any other library
343    facilities.  This must be distributed under the terms of the
344    Sections above.
345
346    b) Give prominent notice with the combined library of the fact
347    that part of it is a work based on the Library, and explaining
348    where to find the accompanying uncombined form of the same work.
349
350  8. You may not copy, modify, sublicense, link with, or distribute
351the Library except as expressly provided under this License.  Any
352attempt otherwise to copy, modify, sublicense, link with, or
353distribute the Library is void, and will automatically terminate your
354rights under this License.  However, parties who have received copies,
355or rights, from you under this License will not have their licenses
356terminated so long as such parties remain in full compliance.
357
358  9. You are not required to accept this License, since you have not
359signed it.  However, nothing else grants you permission to modify or
360distribute the Library or its derivative works.  These actions are
361prohibited by law if you do not accept this License.  Therefore, by
362modifying or distributing the Library (or any work based on the
363Library), you indicate your acceptance of this License to do so, and
364all its terms and conditions for copying, distributing or modifying
365the Library or works based on it.
366
367  10. Each time you redistribute the Library (or any work based on the
368Library), the recipient automatically receives a license from the
369original licensor to copy, distribute, link with or modify the Library
370subject to these terms and conditions.  You may not impose any further
371restrictions on the recipients' exercise of the rights granted herein.
372You are not responsible for enforcing compliance by third parties with
373this License.
374
375  11. If, as a consequence of a court judgment or allegation of patent
376infringement or for any other reason (not limited to patent issues),
377conditions are imposed on you (whether by court order, agreement or
378otherwise) that contradict the conditions of this License, they do not
379excuse you from the conditions of this License.  If you cannot
380distribute so as to satisfy simultaneously your obligations under this
381License and any other pertinent obligations, then as a consequence you
382may not distribute the Library at all.  For example, if a patent
383license would not permit royalty-free redistribution of the Library by
384all those who receive copies directly or indirectly through you, then
385the only way you could satisfy both it and this License would be to
386refrain entirely from distribution of the Library.
387
388If any portion of this section is held invalid or unenforceable under any
389particular circumstance, the balance of the section is intended to apply,
390and the section as a whole is intended to apply in other circumstances.
391
392It is not the purpose of this section to induce you to infringe any
393patents or other property right claims or to contest validity of any
394such claims; this section has the sole purpose of protecting the
395integrity of the free software distribution system which is
396implemented by public license practices.  Many people have made
397generous contributions to the wide range of software distributed
398through that system in reliance on consistent application of that
399system; it is up to the author/donor to decide if he or she is willing
400to distribute software through any other system and a licensee cannot
401impose that choice.
402
403This section is intended to make thoroughly clear what is believed to
404be a consequence of the rest of this License.
405
406  12. If the distribution and/or use of the Library is restricted in
407certain countries either by patents or by copyrighted interfaces, the
408original copyright holder who places the Library under this License may add
409an explicit geographical distribution limitation excluding those countries,
410so that distribution is permitted only in or among countries not thus
411excluded.  In such case, this License incorporates the limitation as if
412written in the body of this License.
413
414  13. The Free Software Foundation may publish revised and/or new
415versions of the Lesser General Public License from time to time.
416Such new versions will be similar in spirit to the present version,
417but may differ in detail to address new problems or concerns.
418
419Each version is given a distinguishing version number.  If the Library
420specifies a version number of this License which applies to it and
421"any later version", you have the option of following the terms and
422conditions either of that version or of any later version published by
423the Free Software Foundation.  If the Library does not specify a
424license version number, you may choose any version ever published by
425the Free Software Foundation.
426
427  14. If you wish to incorporate parts of the Library into other free
428programs whose distribution conditions are incompatible with these,
429write to the author to ask for permission.  For software which is
430copyrighted by the Free Software Foundation, write to the Free
431Software Foundation; we sometimes make exceptions for this.  Our
432decision will be guided by the two goals of preserving the free status
433of all derivatives of our free software and of promoting the sharing
434and reuse of software generally.
435
436                            NO WARRANTY
437
438  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
439WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
440EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
441OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
442KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
443IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
444PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
445LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
446THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
447
448  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
449WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
450AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
451FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
452CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
453LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
454RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
455FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
456SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
457DAMAGES.
