@appendixsubsec Preamble
20
 
21
  The licenses for most software are designed to take away your
22
freedom to share and change it.  By contrast, the GNU General Public
23
Licenses are intended to guarantee your freedom to share and change
24
free software---to make sure the software is free for all its users.
25
 
26
  This license, the Lesser General Public License, applies to some
27
specially designated software---typically libraries---of the Free
28
Software Foundation and other authors who decide to use it.  You can use
29
it too, but we suggest you first think carefully about whether this
30
license or the ordinary General Public License is the better strategy to
31
use in any particular case, based on the explanations below.
32
 
33
  When we speak of free software, we are referring to freedom of use,
34
not price.  Our General Public Licenses are designed to make sure that
35
you have the freedom to distribute copies of free software (and charge
36
for this service if you wish); that you receive source code or can get
37
it if you want it; that you can change the software and use pieces of it
38
in new free programs; and that you are informed that you can do these
39
things.
40
 
41
  To protect your rights, we need to make restrictions that forbid
42
distributors to deny you these rights or to ask you to surrender these
43
rights.  These restrictions translate to certain responsibilities for
44
you if you distribute copies of the library or if you modify it.
45
 
46
  For example, if you distribute copies of the library, whether gratis
47
or for a fee, you must give the recipients all the rights that we gave
48
you.  You must make sure that they, too, receive or can get the source
49
code.  If you link other code with the library, you must provide
50
complete object files to the recipients, so that they can relink them
51
with the library after making changes to the library and recompiling
52
it.  And you must show them these terms so they know their rights.
53
 
54
  We protect your rights with a two-step method: (1) we copyright the
55
library, and (2) we offer you this license, which gives you legal
56
permission to copy, distribute and/or modify the library.
57
 
58
  To protect each distributor, we want to make it very clear that
59
there is no warranty for the free library.  Also, if the library is
60
modified by someone else and passed on, the recipients should know
61
that what they have is not the original version, so that the original
62
author's reputation will not be affected by problems that might be
63
introduced by others.
64
 
65
  Finally, software patents pose a constant threat to the existence of
66
any free program.  We wish to make sure that a company cannot
67
effectively restrict the users of a free program by obtaining a
68
restrictive license from a patent holder.  Therefore, we insist that
69
any patent license obtained for a version of the library must be
70
consistent with the full freedom of use specified in this license.
71
 
72
  Most GNU software, including some libraries, is covered by the
73
ordinary GNU General Public License.  This license, the GNU Lesser
74
General Public License, applies to certain designated libraries, and
75
is quite different from the ordinary General Public License.  We use
76
this license for certain libraries in order to permit linking those
77
libraries into non-free programs.
78
 
79
  When a program is linked with a library, whether statically or using
80
a shared library, the combination of the two is legally speaking a
81
combined work, a derivative of the original library.  The ordinary
82
General Public License therefore permits such linking only if the
83
entire combination fits its criteria of freedom.  The Lesser General
84
Public License permits more lax criteria for linking other code with
85
the library.
86
 
87
  We call this license the @dfn{Lesser} General Public License because it
88
does @emph{Less} to protect the user's freedom than the ordinary General
89
Public License.  It also provides other free software developers Less
90
of an advantage over competing non-free programs.  These disadvantages
91
are the reason we use the ordinary General Public License for many
92
libraries.  However, the Lesser license provides advantages in certain
93
special circumstances.
94
 
95
  For example, on rare occasions, there may be a special need to
96
encourage the widest possible use of a certain library, so that it becomes
97
a de-facto standard.  To achieve this, non-free programs must be
98
allowed to use the library.  A more frequent case is that a free
99
library does the same job as widely used non-free libraries.  In this
100
case, there is little to gain by limiting the free library to free
101
software only, so we use the Lesser General Public License.
102
 
103
  In other cases, permission to use a particular library in non-free
104
programs enables a greater number of people to use a large body of
105
free software.  For example, permission to use the GNU C Library in
106
non-free programs enables many more people to use the whole GNU
107
operating system, as well as its variant, the GNU/Linux operating
108
system.
109
 
110
  Although the Lesser General Public License is Less protective of the
111
users' freedom, it does ensure that the user of a program that is
112
linked with the Library has the freedom and the wherewithal to run
113
that program using a modified version of the Library.
114
 
115
  The precise terms and conditions for copying, distribution and
116
modification follow.  Pay close attention to the difference between a
117
``work based on the library'' and a ``work that uses the library''.  The
118
former contains code derived from the library, whereas the latter must
119
be combined with the library in order to run.

@enumerate 0
130
@item
131
This License Agreement applies to any software library or other program
132
which contains a notice placed by the copyright holder or other
133
authorized party saying it may be distributed under the terms of this
134
Lesser General Public License (also called ``this License'').  Each
135
licensee is addressed as ``you''.
136
 
137
  A ``library'' means a collection of software functions and/or data
138
prepared so as to be conveniently linked with application programs
139
(which use some of those functions and data) to form executables.
140
 
141
  The ``Library'', below, refers to any such software library or work
142
which has been distributed under these terms.  A ``work based on the
143
Library'' means either the Library or any derivative work under
144
copyright law: that is to say, a work containing the Library or a
145
portion of it, either verbatim or with modifications and/or translated
146
straightforwardly into another language.  (Hereinafter, translation is
147
included without limitation in the term ``modification''.)
148
 
149
  ``Source code'' for a work means the preferred form of the work for
150
making modifications to it.  For a library, complete source code means
151
all the source code for all modules it contains, plus any associated
152
interface definition files, plus the scripts used to control compilation
153
and installation of the library.
154
 
155
  Activities other than copying, distribution and modification are not
156
covered by this License; they are outside its scope.  The act of
157
running a program using the Library is not restricted, and output from
158
such a program is covered only if its contents constitute a work based
159
on the Library (independent of the use of the Library in a tool for
160
writing it).  Whether that is true depends on what the Library does
161
and what the program that uses the Library does.
162
 
163
@item
164
You may copy and distribute verbatim copies of the Library's
165
complete source code as you receive it, in any medium, provided that
166
you conspicuously and appropriately publish on each copy an
167
appropriate copyright notice and disclaimer of warranty; keep intact
168
all the notices that refer to this License and to the absence of any
169
warranty; and distribute a copy of this License along with the
170
Library.
171
 
172
  You may charge a fee for the physical act of transferring a copy,
173
and you may at your option offer warranty protection in exchange for a
174
fee.
175
 
176
@item
177
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
@enumerate a
183
@item
184
The modified work must itself be a software library.
185
 
186
@item
187
You must cause the files modified to carry prominent notices
188
stating that you changed the files and the date of any change.
189
 
190
@item
191
You must cause the whole of the work to be licensed at no
192
charge to all third parties under the terms of this License.
193
 
194
@item
195
If a facility in the modified Library refers to a function or a
196
table of data to be supplied by an application program that uses
197
the facility, other than as an argument passed when the facility
198
is invoked, then you must make a good faith effort to ensure that,
199
in the event an application does not supply such function or
200
table, the facility still operates, and performs whatever part of
201
its purpose remains meaningful.
202
 
203
(For example, a function in a library to compute square roots has
204
a purpose that is entirely well-defined independent of the
205
application.  Therefore, Subsection 2d requires that any
206
application-supplied function or table used by this function must
207
be optional: if the application does not supply it, the square
208
root function must still compute square roots.)
209
@end enumerate
210
 
211
These requirements apply to the modified work as a whole.  If
212
identifiable sections of that work are not derived from the Library,
213
and can be reasonably considered independent and separate works in
214
themselves, then this License, and its terms, do not apply to those
215
sections when you distribute them as separate works.  But when you
216
distribute the same sections as part of a whole which is a work based
217
on the Library, the distribution of the whole must be on the terms of
218
this License, whose permissions for other licensees extend to the
219
entire whole, and thus to each and every part regardless of who wrote
220
it.
221
 
222
Thus, it is not the intent of this section to claim rights or contest
223
your rights to work written entirely by you; rather, the intent is to
224
exercise the right to control the distribution of derivative or
225
collective works based on the Library.
226
 
227
In addition, mere aggregation of another work not based on the Library
228
with the Library (or with a work based on the Library) on a volume of
229
a storage or distribution medium does not bring the other work under
230
the scope of this License.
231
 
232
@item
233
You may opt to apply the terms of the ordinary GNU General Public
234
License instead of this License to a given copy of the Library.  To do
235
this, you must alter all the notices that refer to this License, so
236
that they refer to the ordinary GNU General Public License, version 2,
237
instead of to this License.  (If a newer version than version 2 of the
238
ordinary GNU General Public License has appeared, then you can specify
239
that version instead if you wish.)  Do not make any other change in
240
these notices.
241
 
242
  Once this change is made in a given copy, it is irreversible for
243
that copy, so the ordinary GNU General Public License applies to all
244
subsequent copies and derivative works made from that copy.
245
 
246
  This option is useful when you wish to copy part of the code of
247
the Library into a program that is not a library.
248
 
249
@item
250
You may copy and distribute the Library (or a portion or
251
derivative of it, under Section 2) in object code or executable form
252
under the terms of Sections 1 and 2 above provided that you accompany
253
it with the complete corresponding machine-readable source code, which
254
must be distributed under the terms of Sections 1 and 2 above on a
255
medium customarily used for software interchange.
256
 
257
  If distribution of object code is made by offering access to copy
258
from a designated place, then offering equivalent access to copy the
259
source code from the same place satisfies the requirement to
260
distribute the source code, even though third parties are not
261
compelled to copy the source along with the object code.
262
 
263
@item
264
A program that contains no derivative of any portion of the
265
Library, but is designed to work with the Library by being compiled or
266
linked with it, is called a ``work that uses the Library''.  Such a
267
work, in isolation, is not a derivative work of the Library, and
268
therefore falls outside the scope of this License.
269
 
270
  However, linking a ``work that uses the Library'' with the Library
271
creates an executable that is a derivative of the Library (because it
272
contains portions of the Library), rather than a ``work that uses the
273
library''.  The executable is therefore covered by this License.
274
Section 6 states terms for distribution of such executables.
275
 
276
  When a ``work that uses the Library'' uses material from a header file
277
that is part of the Library, the object code for the work may be a
278
derivative work of the Library even though the source code is not.
279
Whether this is true is especially significant if the work can be
280
linked without the Library, or if the work is itself a library.  The
281
threshold for this to be true is not precisely defined by law.
282
 
283
  If such an object file uses only numerical parameters, data
284
structure layouts and accessors, and small macros and small inline
285
functions (ten lines or less in length), then the use of the object
286
file is unrestricted, regardless of whether it is legally a derivative
287
work.  (Executables containing this object code plus portions of the
288
Library will still fall under Section 6.)
289
 
290
  Otherwise, if the work is a derivative of the Library, you may
291
distribute the object code for the work under the terms of Section 6.
292
Any executables containing that work also fall under Section 6,
293
whether or not they are linked directly with the Library itself.
294
 
295
@item
296
As an exception to the Sections above, you may also combine or
297
link a ``work that uses the Library'' with the Library to produce a
298
work containing portions of the Library, and distribute that work
299
under terms of your choice, provided that the terms permit
300
modification of the work for the customer's own use and reverse
301
engineering for debugging such modifications.
302
 
303
  You must give prominent notice with each copy of the work that the
304
Library is used in it and that the Library and its use are covered by
305
this License.  You must supply a copy of this License.  If the work
306
during execution displays copyright notices, you must include the
307
copyright notice for the Library among them, as well as a reference
308
directing the user to the copy of this License.  Also, you must do one
309
of these things:
310
 
311
@enumerate a
312
@item
313
Accompany the work with the complete corresponding
314
machine-readable source code for the Library including whatever
315
changes were used in the work (which must be distributed under
316
Sections 1 and 2 above); and, if the work is an executable linked
317
with the Library, with the complete machine-readable ``work that
318
uses the Library'', as object code and/or source code, so that the
319
user can modify the Library and then relink to produce a modified
320
executable containing the modified Library.  (It is understood
321
that the user who changes the contents of definitions files in the
322
Library will not necessarily be able to recompile the application
323
to use the modified definitions.)
324
 
325
@item
326
Use a suitable shared library mechanism for linking with the Library.  A
327
suitable mechanism is one that (1) uses at run time a copy of the
328
library already present on the user's computer system, rather than
329
copying library functions into the executable, and (2) will operate
330
properly with a modified version of the library, if the user installs
331
one, as long as the modified version is interface-compatible with the
332
version that the work was made with.
333
 
334
@item
335
Accompany the work with a written offer, valid for at
336
least three years, to give the same user the materials
337
specified in Subsection 6a, above, for a charge no more
338
than the cost of performing this distribution.
339
 
340
@item
341
If distribution of the work is made by offering access to copy
342
from a designated place, offer equivalent access to copy the above
343
specified materials from the same place.
344
 
345
@item
346
Verify that the user has already received a copy of these
347
materials or that you have already sent this user a copy.
348
@end enumerate
349
 
350
  For an executable, the required form of the ``work that uses the
351
Library'' must include any data and utility programs needed for
352
reproducing the executable from it.  However, as a special exception,
353
the materials to be distributed need not include anything that is
354
normally distributed (in either source or binary form) with the major
355
components (compiler, kernel, and so on) of the operating system on
356
which the executable runs, unless that component itself accompanies the
357
executable.
358
 
359
  It may happen that this requirement contradicts the license
360
restrictions of other proprietary libraries that do not normally
361
accompany the operating system.  Such a contradiction means you cannot
362
use both them and the Library together in an executable that you
363
distribute.
364
 
365
@item
366
You may place library facilities that are a work based on the
367
Library side-by-side in a single library together with other library
368
facilities not covered by this License, and distribute such a combined
369
library, provided that the separate distribution of the work based on
370
the Library and of the other library facilities is otherwise
371
permitted, and provided that you do these two things:
372
 
373
@enumerate a
374
@item
375
Accompany the combined library with a copy of the same work
376
based on the Library, uncombined with any other library
377
facilities.  This must be distributed under the terms of the
378
Sections above.
379
 
380
@item
381
Give prominent notice with the combined library of the fact
382
that part of it is a work based on the Library, and explaining
383
where to find the accompanying uncombined form of the same work.
384
@end enumerate
385
 
386
@item
387
You may not copy, modify, sublicense, link with, or distribute
388
the Library except as expressly provided under this License.  Any
389
attempt otherwise to copy, modify, sublicense, link with, or
390
distribute the Library is void, and will automatically terminate your
391
rights under this License.  However, parties who have received copies,
392
or rights, from you under this License will not have their licenses
393
terminated so long as such parties remain in full compliance.
394
 
395
@item
396
You are not required to accept this License, since you have not
397
signed it.  However, nothing else grants you permission to modify or
398
distribute the Library or its derivative works.  These actions are
399
prohibited by law if you do not accept this License.  Therefore, by
400
modifying or distributing the Library (or any work based on the
401
Library), you indicate your acceptance of this License to do so, and
402
all its terms and conditions for copying, distributing or modifying
403
the Library or works based on it.
404
 
405
@item
406
Each time you redistribute the Library (or any work based on the
407
Library), the recipient automatically receives a license from the
408
original licensor to copy, distribute, link with or modify the Library
409
subject to these terms and conditions.  You may not impose any further
410
restrictions on the recipients' exercise of the rights granted herein.
411
You are not responsible for enforcing compliance by third parties with
412
this License.
413
 
414
@item
415
If, as a consequence of a court judgment or allegation of patent
416
infringement or for any other reason (not limited to patent issues),
417
conditions are imposed on you (whether by court order, agreement or
418
otherwise) that contradict the conditions of this License, they do not
419
excuse you from the conditions of this License.  If you cannot
420
distribute so as to satisfy simultaneously your obligations under this
421
License and any other pertinent obligations, then as a consequence you
422
may not distribute the Library at all.  For example, if a patent
423
license would not permit royalty-free redistribution of the Library by
424
all those who receive copies directly or indirectly through you, then
425
the only way you could satisfy both it and this License would be to
426
refrain entirely from distribution of the Library.
427
 
428
If any portion of this section is held invalid or unenforceable under any
429
particular circumstance, the balance of the section is intended to apply,
430
and the section as a whole is intended to apply in other circumstances.
431
 
432
It is not the purpose of this section to induce you to infringe any
433
patents or other property right claims or to contest validity of any
434
such claims; this section has the sole purpose of protecting the
435
integrity of the free software distribution system which is
436
implemented by public license practices.  Many people have made
437
generous contributions to the wide range of software distributed
438
through that system in reliance on consistent application of that
439
system; it is up to the author/donor to decide if he or she is willing
440
to distribute software through any other system and a licensee cannot
441
impose that choice.
442
 
443
This section is intended to make thoroughly clear what is believed to
444
be a consequence of the rest of this License.
445
 
446
@item
447
If the distribution and/or use of the Library is restricted in
448
certain countries either by patents or by copyrighted interfaces, the
449
original copyright holder who places the Library under this License may add
450
an explicit geographical distribution limitation excluding those countries,
451
so that distribution is permitted only in or among countries not thus
452
excluded.  In such case, this License incorporates the limitation as if
453
written in the body of this License.
454
 
455
@item
456
The Free Software Foundation may publish revised and/or new
457
versions of the Lesser General Public License from time to time.
458
Such new versions will be similar in spirit to the present version,
459
but may differ in detail to address new problems or concerns.
460
 
461
Each version is given a distinguishing version number.  If the Library
462

@appendixsubsec How to Apply These Terms to Your New Libraries
519
 
520
  If you develop a new library, and you want it to be of the greatest
521
possible use to the public, we recommend making it free software that
522
everyone can redistribute and change.  You can do so by permitting
523
redistribution under these terms (or, alternatively, under the terms of the
524
ordinary General Public License).
525
 
526
  To apply these terms, attach the following notices to the library.  It is
527
safest to attach them to the start of each source file to most effectively
528
convey the exclusion of warranty; and each file should have at least the
529
``copyright'' line and a pointer to where the full notice is found.

Also add information on how to contact you by electronic and paper mail.
552
 
553
You should also get your employer (if you work as a programmer) or your
554
school, if any, to sign a ``copyright disclaimer'' for the library, if
555
necessary.  Here is a sample; alter the names:
