Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
27
Everyone is permitted to copy and distribute verbatim copies
28
of this license document, but changing it is not allowed.
31
This version of the GNU Lesser General Public License incorporates
32
the terms and conditions of version 3 of the GNU General Public
33
License, supplemented by the additional permissions listed below.
35
0. Additional Definitions.
37
As used herein, "this License" refers to version 3 of the GNU Lesser
38
General Public License, and the "GNU GPL" refers to version 3 of the GNU
39
General Public License.
41
"The Library" refers to a covered work governed by this License,
42
other than an Application or a Combined Work as defined below.
44
An "Application" is any work that makes use of an interface provided
45
by the Library, but which is not otherwise based on the Library.
46
Defining a subclass of a class defined by the Library is deemed a mode
47
of using an interface provided by the Library.
49
A "Combined Work" is a work produced by combining or linking an
50
Application with the Library. The particular version of the Library
51
with which the Combined Work was made is also called the "Linked
54
The "Minimal Corresponding Source" for a Combined Work means the
55
Corresponding Source for the Combined Work, excluding any source code
56
for portions of the Combined Work that, considered in isolation, are
57
based on the Application, and not on the Linked Version.
59
The "Corresponding Application Code" for a Combined Work means the
60
object code and/or source code for the Application, including any data
61
and utility programs needed for reproducing the Combined Work from the
62
Application, but excluding the System Libraries of the Combined Work.
64
1. Exception to Section 3 of the GNU GPL.
66
You may convey a covered work under sections 3 and 4 of this License
67
without being bound by section 3 of the GNU GPL.
69
2. Conveying Modified Versions.
71
If you modify a copy of the Library, and, in your modifications, a
72
facility refers to a function or data to be supplied by an Application
73
that uses the facility (other than as an argument passed when the
74
facility is invoked), then you may convey a copy of the modified
77
a) under this License, provided that you make a good faith effort to
78
ensure that, in the event an Application does not supply the
79
function or data, the facility still operates, and performs
80
whatever part of its purpose remains meaningful, or
82
b) under the GNU GPL, with none of the additional permissions of
83
this License applicable to that copy.
85
3. Object Code Incorporating Material from Library Header Files.
87
The object code form of an Application may incorporate material from
88
a header file that is part of the Library. You may convey such object
89
code under terms of your choice, provided that, if the incorporated
90
material is not limited to numerical parameters, data structure
91
layouts and accessors, or small macros, inline functions and templates
92
(ten or fewer lines in length), you do both of the following:
94
a) Give prominent notice with each copy of the object code that the
95
Library is used in it and that the Library and its use are
96
covered by this License.
98
b) Accompany the object code with a copy of the GNU GPL and this license
103
You may convey a Combined Work under terms of your choice that,
104
taken together, effectively do not restrict modification of the
105
portions of the Library contained in the Combined Work and reverse
106
engineering for debugging such modifications, if you also do each of
109
a) Give prominent notice with each copy of the Combined Work that
110
the Library is used in it and that the Library and its use are
111
covered by this License.
113
b) Accompany the Combined Work with a copy of the GNU GPL and this license
116
c) For a Combined Work that displays copyright notices during
117
execution, include the copyright notice for the Library among
118
these notices, as well as a reference directing the user to the
119
copies of the GNU GPL and this license document.
121
d) Do one of the following:
123
0) Convey the Minimal Corresponding Source under the terms of this
124
License, and the Corresponding Application Code in a form
125
suitable for, and under terms that permit, the user to
126
recombine or relink the Application with a modified version of
127
the Linked Version to produce a modified Combined Work, in the
128
manner specified by section 6 of the GNU GPL for conveying
129
Corresponding Source.
131
1) Use a suitable shared library mechanism for linking with the
132
Library. A suitable mechanism is one that (a) uses at run time
133
a copy of the Library already present on the user's computer
134
system, and (b) will operate properly with a modified version
135
of the Library that is interface-compatible with the Linked
138
e) Provide Installation Information, but only if you would otherwise
139
be required to provide such information under section 6 of the
140
GNU GPL, and only to the extent that such information is
141
necessary to install and execute a modified version of the
142
Combined Work produced by recombining or relinking the
143
Application with a modified version of the Linked Version. (If
144
you use option 4d0, the Installation Information must accompany
145
the Minimal Corresponding Source and Corresponding Application
146
Code. If you use option 4d1, you must provide the Installation
147
Information in the manner specified by section 6 of the GNU GPL
148
for conveying Corresponding Source.)
150
5. Combined Libraries.
152
You may place library facilities that are a work based on the
153
Library side by side in a single library together with other library
154
facilities that are not Applications and are not covered by this
155
License, and convey such a combined library under terms of your
156
choice, if you do both of the following:
158
a) Accompany the combined library with a copy of the same work based
159
on the Library, uncombined with any other library facilities,
160
conveyed under the terms of this License.
162
b) Give prominent notice with the combined library that part of it
163
is a work based on the Library, and explaining where to find the
164
accompanying uncombined form of the same work.
166
6. Revised Versions of the GNU Lesser General Public License.
168
The Free Software Foundation may publish revised and/or new versions
169
of the GNU Lesser General Public License from time to time. Such new
170
versions will be similar in spirit to the present version, but may
171
differ in detail to address new problems or concerns.
173
Each version is given a distinguishing version number. If the
174
Library as you received it specifies that a certain numbered version
175
of the GNU Lesser General Public License "or any later version"
176
applies to it, you have the option of following the terms and
177
conditions either of that published version or of any later version
178
published by the Free Software Foundation. If the Library as you
179
received it does not specify a version number of the GNU Lesser
180
General Public License, you may choose any version of the GNU Lesser
181
General Public License ever published by the Free Software Foundation.
183
If the Library as you received it specifies that a proxy can decide
184
whether future versions of the GNU Lesser General Public License shall
185
apply, that proxy's public statement of acceptance of any version is
186
permanent authorization for you to choose that version for the
