GNU LESSER GENERAL PUBLIC LICENSE

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

13. The Free Software Foundation may publish revised and/or new
|
|
|
301 |
versions of the Lesser General Public License from time to time.
|
|
|
302 |
Such new versions will be similar in spirit to the present version,
|
|
|
303 |
but may differ in detail to address new problems or concerns.
|
|
|
304 |
|
|
|
305 |
Each version is given a distinguishing version number. If the Library
|
|
|
306 |
specifies a version number of this License which applies to it and
|
|
|
307 |
"any later version", you have the option of following the terms and
|
|
|
308 |
conditions either of that version or of any later version published by
|
|
|
309 |
the Free Software Foundation. If the Library does not specify a
|
|
|
310 |
license version number, you may choose any version ever published by
|
|
|
311 |
the Free Software Foundation.
|
|
|
312 |
|
|
|
313 |
14. If you wish to incorporate parts of the Library into other free
|
|
|
314 |
programs whose distribution conditions are incompatible with these,
|
|
|
315 |
write to the author to ask for permission. For software which is
|
|
|
316 |
copyrighted by the Free Software Foundation, write to the Free
|
|
|
317 |
Software Foundation; we sometimes make exceptions for this. Our
|
|
|
318 |
decision will be guided by the two goals of preserving the free status
|
|
|
319 |
of all derivatives of our free software and of promoting the sharing
|
|
|
320 |
and reuse of software generally.

15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
|
325 |
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
|
326 |
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
|
327 |
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
|
|
328 |
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
|
|
329 |
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
|
|
330 |
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
|
|
331 |
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
|
332 |
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
|
333 |
|
|
|
334 |
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
|
335 |
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
|
336 |
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
|
|
337 |
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
|
|
338 |
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
|
|
339 |
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
|
|
340 |
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
|
|
341 |
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
|
|
342 |
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
|
|
343 |
DAMAGES.
