 Everyone is permitted to copy and distribute verbatim copies

 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
10
 as the successor of the GNU Library Public License, version 2, hence
11
 the version number 2.1.]

		  GNU LESSER GENERAL PUBLIC LICENSE
15
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
16
 
17
  0. This License Agreement applies to any software library or other
18
program which contains a notice placed by the copyright holder or
19
other authorized party saying it may be distributed under the terms of
20
this Lesser General Public License (also called "this License").
21
Each licensee is addressed as "you".
22
 
23
  A "library" means a collection of software functions and/or data
24
prepared so as to be conveniently linked with application programs
25
(which use some of those functions and data) to form executables.
26
 
27
  The "Library", below, refers to any such software library or work
28
which has been distributed under these terms.  A "work based on the
29
Library" means either the Library or any derivative work under
30
copyright law: that is to say, a work containing the Library or a
31
portion of it, either verbatim or with modifications and/or translated
32
straightforwardly into another language.  (Hereinafter, translation is
33
included without limitation in the term "modification".)
34
 
35
  "Source code" for a work means the preferred form of the work for
36
making modifications to it.  For a library, complete source code means
37
all the source code for all modules it contains, plus any associated
38
interface definition files, plus the scripts used to control compilation
39
and installation of the library.
40
 
41
  Activities other than copying, distribution and modification are not
42
covered by this License; they are outside its scope.  The act of
43
running a program using the Library is not restricted, and output from
44
such a program is covered only if its contents constitute a work based
45
on the Library (independent of the use of the Library in a tool for
46
writing it).  Whether that is true depends on what the Library does
47
and what the program that uses the Library does.
48
 
49
  1. You may copy and distribute verbatim copies of the Library's
50
complete source code as you receive it, in any medium, provided that
51
you conspicuously and appropriately publish on each copy an
52
appropriate copyright notice and disclaimer of warranty; keep intact
53
all the notices that refer to this License and to the absence of any
54
warranty; and distribute a copy of this License along with the
55
Library.
56
 
57
  You may charge a fee for the physical act of transferring a copy,
58
and you may at your option offer warranty protection in exchange for a
59
fee.
60
 
61
  2. You may modify your copy or copies of the Library or any portion
62
of it, thus forming a work based on the Library, and copy and
63
distribute such modifications or work under the terms of Section 1
64
above, provided that you also meet all of these conditions:
65
 
66
    a) The modified work must itself be a software library.
67
 
68
    b) You must cause the files modified to carry prominent notices
69
    stating that you changed the files and the date of any change.
70
 
71
    c) You must cause the whole of the work to be licensed at no
72
    charge to all third parties under the terms of this License.
73
 
74
    d) If a facility in the modified Library refers to a function or a
75
    table of data to be supplied by an application program that uses
76
    the facility, other than as an argument passed when the facility
77
    is invoked, then you must make a good faith effort to ensure that,
78
    in the event an application does not supply such function or
79
    table, the facility still operates, and performs whatever part of
80
    its purpose remains meaningful.
81
 
82
    (For example, a function in a library to compute square roots has
83
    a purpose that is entirely well-defined independent of the
84
    application.  Therefore, Subsection 2d requires that any
85
    application-supplied function or table used by this function must
86
    be optional: if the application does not supply it, the square
87
    root function must still compute square roots.)
88
 
89
These requirements apply to the modified work as a whole.  If
90
identifiable sections of that work are not derived from the Library,
91
and can be reasonably considered independent and separate works in
92
themselves, then this License, and its terms, do not apply to those
93
sections when you distribute them as separate works.  But when you
94
distribute the same sections as part of a whole which is a work based
95
on the Library, the distribution of the whole must be on the terms of
96
this License, whose permissions for other licensees extend to the
97
entire whole, and thus to each and every part regardless of who wrote
98
it.
99
 
100
Thus, it is not the intent of this section to claim rights or contest
101
your rights to work written entirely by you; rather, the intent is to
102
exercise the right to control the distribution of derivative or
103
collective works based on the Library.
104
 
105
In addition, mere aggregation of another work not based on the Library
106
with the Library (or with a work based on the Library) on a volume of
107
a storage or distribution medium does not bring the other work under
108
the scope of this License.
109
 
110
  3. You may opt to apply the terms of the ordinary GNU General Public
111
License instead of this License to a given copy of the Library.  To do
112
this, you must alter all the notices that refer to this License, so
113
that they refer to the ordinary GNU General Public License, version 2,
114
instead of to this License.  (If a newer version than version 2 of the
115
ordinary GNU General Public License has appeared, then you can specify
116
that version instead if you wish.)  Do not make any other change in
117
these notices.
118
 
119
  Once this change is made in a given copy, it is irreversible for
120
that copy, so the ordinary GNU General Public License applies to all
121
subsequent copies and derivative works made from that copy.
122
 
123
  This option is useful when you wish to copy part of the code of
124
the Library into a program that is not a library.
125
 
126
  4. You may copy and distribute the Library (or a portion or
127
derivative of it, under Section 2) in object code or executable form
128
under the terms of Sections 1 and 2 above provided that you accompany
129
it with the complete corresponding machine-readable source code, which
130
must be distributed under the terms of Sections 1 and 2 above on a
131
medium customarily used for software interchange.
132
 
133
  If distribution of object code is made by offering access to copy
134
from a designated place, then offering equivalent access to copy the
135
source code from the same place satisfies the requirement to
136
distribute the source code, even though third parties are not
137
compelled to copy the source along with the object code.
138
 
139
  5. A program that contains no derivative of any portion of the
140
Library, but is designed to work with the Library by being compiled or
141
linked with it, is called a "work that uses the Library".  Such a
142
work, in isolation, is not a derivative work of the Library, and
143
therefore falls outside the scope of this License.
144
 
145
  However, linking a "work that uses the Library" with the Library
146
creates an executable that is a derivative of the Library (because it
147
contains portions of the Library), rather than a "work that uses the
148
library".  The executable is therefore covered by this License.
149
Section 6 states terms for distribution of such executables.
150
 
151
  When a "work that uses the Library" uses material from a header file
152
that is part of the Library, the object code for the work may be a
153
derivative work of the Library even though the source code is not.
154
Whether this is true is especially significant if the work can be
155
linked without the Library, or if the work is itself a library.  The
156
threshold for this to be true is not precisely defined by law.
157
 
158
  If such an object file uses only numerical parameters, data
159
structure layouts and accessors, and small macros and small inline
160
functions (ten lines or less in length), then the use of the object
161
file is unrestricted, regardless of whether it is legally a derivative
162
work.  (Executables containing this object code plus portions of the
163
Library will still fall under Section 6.)
164
 
165
  Otherwise, if the work is a derivative of the Library, you may
166
distribute the object code for the work under the terms of Section 6.
167
Any executables containing that work also fall under Section 6,
168
whether or not they are linked directly with the Library itself.
169
 
170
  6. As an exception to the Sections above, you may also combine or
171
link a "work that uses the Library" with the Library to produce a
172
work containing portions of the Library, and distribute that work
173
under terms of your choice, provided that the terms permit
174
modification of the work for the customer's own use and reverse
175
engineering for debugging such modifications.
176
 
177
  You must give prominent notice with each copy of the work that the
178
Library is used in it and that the Library and its use are covered by
179
this License.  You must supply a copy of this License.  If the work
180
during execution displays copyright notices, you must include the
181
copyright notice for the Library among them, as well as a reference
182
directing the user to the copy of this License.  Also, you must do one
183
of these things:
184
 
185
    a) Accompany the work with the complete corresponding
186
    machine-readable source code for the Library including whatever
187
    changes were used in the work (which must be distributed under
188
    Sections 1 and 2 above); and, if the work is an executable linked
189
    with the Library, with the complete machine-readable "work that
190
    uses the Library", as object code and/or source code, so that the
191
    user can modify the Library and then relink to produce a modified
192
    executable containing the modified Library.  (It is understood
193
    that the user who changes the contents of definitions files in the
194
    Library will not necessarily be able to recompile the application
195
    to use the modified definitions.)
196
 
197
    b) Use a suitable shared library mechanism for linking with the
198
    Library.  A suitable mechanism is one that (1) uses at run time a
199
    copy of the library already present on the user's computer system,
200
    rather than copying library functions into the executable, and (2)
201
    will operate properly with a modified version of the library, if
202
    the user installs one, as long as the modified version is
203
    interface-compatible with the version that the work was made with.
204
 
205
    c) Accompany the work with a written offer, valid for at
206
    least three years, to give the same user the materials
207
    specified in Subsection 6a, above, for a charge no more
208
    than the cost of performing this distribution.
209
 
210
    d) If distribution of the work is made by offering access to copy
211
    from a designated place, offer equivalent access to copy the above
212
    specified materials from the same place.
213
 
214
    e) Verify that the user has already received a copy of these
215
    materials or that you have already sent this user a copy.
216
 
217
  For an executable, the required form of the "work that uses the
218
Library" must include any data and utility programs needed for
219
reproducing the executable from it.  However, as a special exception,
220
the materials to be distributed need not include anything that is
221
normally distributed (in either source or binary form) with the major
222
components (compiler, kernel, and so on) of the operating system on
223
which the executable runs, unless that component itself accompanies
224
the executable.
225
 
226
  It may happen that this requirement contradicts the license
227
restrictions of other proprietary libraries that do not normally
228
accompany the operating system.  Such a contradiction means you cannot
229
use both them and the Library together in an executable that you
230
distribute.
231
 
232
  7. You may place library facilities that are a work based on the
233
Library side-by-side in a single library together with other library
234
facilities not covered by this License, and distribute such a combined
235
library, provided that the separate distribution of the work based on
236
the Library and of the other library facilities is otherwise
237
permitted, and provided that you do these two things:
238
 
239
    a) Accompany the combined library with a copy of the same work
240
    based on the Library, uncombined with any other library
241
    facilities.  This must be distributed under the terms of the
242
    Sections above.
243
 
244
    b) Give prominent notice with the combined library of the fact
245
    that part of it is a work based on the Library, and explaining
246
    where to find the accompanying uncombined form of the same work.
247
 
248
  8. You may not copy, modify, sublicense, link with, or distribute
249
the Library except as expressly provided under this License.  Any
250
attempt otherwise to copy, modify, sublicense, link with, or
251
distribute the Library is void, and will automatically terminate your
252
rights under this License.  However, parties who have received copies,
253
or rights, from you under this License will not have their licenses
254
terminated so long as such parties remain in full compliance.
255
 
256
  9. You are not required to accept this License, since you have not
257
signed it.  However, nothing else grants you permission to modify or
258
distribute the Library or its derivative works.  These actions are
259
prohibited by law if you do not accept this License.  Therefore, by
260
modifying or distributing the Library (or any work based on the
261
Library), you indicate your acceptance of this License to do so, and
262
all its terms and conditions for copying, distributing or modifying
263
the Library or works based on it.
264
 
265
  10. Each time you redistribute the Library (or any work based on the
266
Library), the recipient automatically receives a license from the
267
original licensor to copy, distribute, link with or modify the Library
268
subject to these terms and conditions.  You may not impose any further
269
restrictions on the recipients' exercise of the rights granted herein.
270
You are not responsible for enforcing compliance by third parties with
271
this License.
272
 
273
  11. If, as a consequence of a court judgment or allegation of patent
274
infringement or for any other reason (not limited to patent issues),
275
conditions are imposed on you (whether by court order, agreement or
276
otherwise) that contradict the conditions of this License, they do not
277
excuse you from the conditions of this License.  If you cannot
278
distribute so as to satisfy simultaneously your obligations under this
279
License and any other pertinent obligations, then as a consequence you
280
may not distribute the Library at all.  For example, if a patent
281
license would not permit royalty-free redistribution of the Library by
282
all those who receive copies directly or indirectly through you, then
283
the only way you could satisfy both it and this License would be to
284
refrain entirely from distribution of the Library.
285
 
286
If any portion of this section is held invalid or unenforceable under any
287
particular circumstance, the balance of the section is intended to apply,
288
and the section as a whole is intended to apply in other circumstances.
289
 
290
It is not the purpose of this section to induce you to infringe any
291
patents or other property right claims or to contest validity of any
292
such claims; this section has the sole purpose of protecting the
293
integrity of the free software distribution system which is
294
implemented by public license practices.  Many people have made
295
generous contributions to the wide range of software distributed
296
through that system in reliance on consistent application of that
297
system; it is up to the author/donor to decide if he or she is willing
298
to distribute software through any other system and a licensee cannot
299
impose that choice.
300
 
301
This section is intended to make thoroughly clear what is believed to
302
be a consequence of the rest of this License.
303
 
304
  12. If the distribution and/or use of the Library is restricted in
305
certain countries either by patents or by copyrighted interfaces, the
306
original copyright holder who places the Library under this License may add
307
an explicit geographical distribution limitation excluding those countries,
308
so that distribution is permitted only in or among countries not thus
309
excluded.  In such case, this License incorporates the limitation as if
310
written in the body of this License.
311
 
312
  13. The Free Software Foundation may publish revised and/or new
313
versions of the Lesser General Public License from time to time.
314
Such new versions will be similar in spirit to the present version,
315
but may differ in detail to address new problems or concerns.
316
 
317
Each version is given a distinguishing version number.  If the Library
318
specifies a version number of this License which applies to it and
319
"any later version", you have the option of following the terms and
320
conditions either of that version or of any later version published by
321
the Free Software Foundation.  If the Library does not specify a
322
license version number, you may choose any version ever published by
323
the Free Software Foundation.
324
 
325
  14. If you wish to incorporate parts of the Library into other free
326
programs whose distribution conditions are incompatible with these,
327
write to the author to ask for permission.  For software which is
328
copyrighted by the Free Software Foundation, write to the Free
329
Software Foundation; we sometimes make exceptions for this.  Our
330
decision will be guided by the two goals of preserving the free status
331
of all derivatives of our free software and of promoting the sharing
332
and reuse of software generally.
333
 
334
			    NO WARRANTY
335
 
336
  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
337
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
338
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
339
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
340
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
341
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
342
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
343
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
344
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
345
 
346
  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
347
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
348
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
349
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
350
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
351
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
352
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
353
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
354
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
355
DAMAGES.
