Everyone is permitted to copy and distribute verbatim copies
7
of this license document, but changing it is not allowed.
10
This version of the GNU Lesser General Public License incorporates
11
the terms and conditions of version 3 of the GNU General Public
12
License, supplemented by the additional permissions listed below.
14
0. Additional Definitions.
16
As used herein, "this License" refers to version 3 of the GNU Lesser
17
General Public License, and the "GNU GPL" refers to version 3 of the GNU
18
General Public License.
20
"The Library" refers to a covered work governed by this License,
21
other than an Application or a Combined Work as defined below.
23
An "Application" is any work that makes use of an interface provided
24
by the Library, but which is not otherwise based on the Library.
25
Defining a subclass of a class defined by the Library is deemed a mode
26
of using an interface provided by the Library.
28
A "Combined Work" is a work produced by combining or linking an
29
Application with the Library. The particular version of the Library
30
with which the Combined Work was made is also called the "Linked
33
The "Minimal Corresponding Source" for a Combined Work means the
34
Corresponding Source for the Combined Work, excluding any source code
35
for portions of the Combined Work that, considered in isolation, are
36
based on the Application, and not on the Linked Version.
38
The "Corresponding Application Code" for a Combined Work means the
39
object code and/or source code for the Application, including any data
40
and utility programs needed for reproducing the Combined Work from the
41
Application, but excluding the System Libraries of the Combined Work.
43
1. Exception to Section 3 of the GNU GPL.
45
You may convey a covered work under sections 3 and 4 of this License
46
without being bound by section 3 of the GNU GPL.
48
2. Conveying Modified Versions.
50
If you modify a copy of the Library, and, in your modifications, a
51
facility refers to a function or data to be supplied by an Application
52
that uses the facility (other than as an argument passed when the
53
facility is invoked), then you may convey a copy of the modified
56
a) under this License, provided that you make a good faith effort to
57
ensure that, in the event an Application does not supply the
58
function or data, the facility still operates, and performs
59
whatever part of its purpose remains meaningful, or
61
b) under the GNU GPL, with none of the additional permissions of
62
this License applicable to that copy.
64
3. Object Code Incorporating Material from Library Header Files.
66
The object code form of an Application may incorporate material from
67
a header file that is part of the Library. You may convey such object
68
code under terms of your choice, provided that, if the incorporated
69
material is not limited to numerical parameters, data structure
70
layouts and accessors, or small macros, inline functions and templates
71
(ten or fewer lines in length), you do both of the following:
73
a) Give prominent notice with each copy of the object code that the
74
Library is used in it and that the Library and its use are
75
covered by this License.
77
b) Accompany the object code with a copy of the GNU GPL and this license
82
You may convey a Combined Work under terms of your choice that,
83
taken together, effectively do not restrict modification of the
84
portions of the Library contained in the Combined Work and reverse
85
engineering for debugging such modifications, if you also do each of
88
a) Give prominent notice with each copy of the Combined Work that
89
the Library is used in it and that the Library and its use are
90
covered by this License.
92
b) Accompany the Combined Work with a copy of the GNU GPL and this license
95
c) For a Combined Work that displays copyright notices during
96
execution, include the copyright notice for the Library among
97
these notices, as well as a reference directing the user to the
98
copies of the GNU GPL and this license document.
100
d) Do one of the following:
102
0) Convey the Minimal Corresponding Source under the terms of this
103
License, and the Corresponding Application Code in a form
104
suitable for, and under terms that permit, the user to
105
recombine or relink the Application with a modified version of
106
the Linked Version to produce a modified Combined Work, in the
107
manner specified by section 6 of the GNU GPL for conveying
108
Corresponding Source.
110
1) Use a suitable shared library mechanism for linking with the
111
Library. A suitable mechanism is one that (a) uses at run time
112
a copy of the Library already present on the user's computer
113
system, and (b) will operate properly with a modified version
114
of the Library that is interface-compatible with the Linked
117
e) Provide Installation Information, but only if you would otherwise
118
be required to provide such information under section 6 of the
119
GNU GPL, and only to the extent that such information is
120
necessary to install and execute a modified version of the
121
Combined Work produced by recombining or relinking the
122
Application with a modified version of the Linked Version. (If
123
you use option 4d0, the Installation Information must accompany
124
the Minimal Corresponding Source and Corresponding Application
125
Code. If you use option 4d1, you must provide the Installation
126
Information in the manner specified by section 6 of the GNU GPL
127
for conveying Corresponding Source.)
129
5. Combined Libraries.
131
You may place library facilities that are a work based on the
132
Library side by side in a single library together with other library
133
facilities that are not Applications and are not covered by this
134
License, and convey such a combined library under terms of your
135
choice, if you do both of the following:
137
a) Accompany the combined library with a copy of the same work based
138
on the Library, uncombined with any other library facilities,
139
conveyed under the terms of this License.
141
b) Give prominent notice with the combined library that part of it
142
is a work based on the Library, and explaining where to find the
143
accompanying uncombined form of the same work.
145
6. Revised Versions of the GNU Lesser General Public License.
147
The Free Software Foundation may publish revised and/or new versions
148
of the GNU Lesser General Public License from time to time. Such new
149
versions will be similar in spirit to the present version, but may
150
differ in detail to address new problems or concerns.
152
Each version is given a distinguishing version number. If the
153
Library as you received it specifies that a certain numbered version
154
of the GNU Lesser General Public License "or any later version"
155
applies to it, you have the option of following the terms and
156
conditions either of that published version or of any later version
157
published by the Free Software Foundation. If the Library as you
158
received it does not specify a version number of the GNU Lesser
159
General Public License, you may choose any version of the GNU Lesser
160
General Public License ever published by the Free Software Foundation.
162
If the Library as you received it specifies that a proxy can decide
163
whether future versions of the GNU Lesser General Public License shall
164
apply, that proxy's public statement of acceptance of any version is
165
permanent authorization for you to choose that version for the
