9 GNU LESSER GENERAL PUBLIC LICENSE
10 Version 3, 29 June 2007
11 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
13 Everyone is permitted to copy and distribute verbatim copies of this
14 license document, but changing it is not allowed.
15 This version of the GNU Lesser General Public License incorporates the
17 terms and conditions of version 3 of the GNU General Public License,
18 supplemented by the additional permissions listed below.
19
21 As used herein, "this License" refers to version 3 of the GNU Lesser
22 General Public License, and the "GNU GPL" refers to version 3 of the
23 GNU General Public License.
24 "The Library" refers to a covered work governed by this License, other
26 than an Application or a Combined Work as defined below.
27 An "Application" is any work that makes use of an interface provided by
29 the Library, but which is not otherwise based on the Library. Defining
30 a subclass of a class defined by the Library is deemed a mode of using
31 an interface provided by the Library.
32 A "Combined Work" is a work produced by combining or linking an Appli‐
34 cation with the Library. The particular version of the Library with
35 which the Combined Work was made is also called the "Linked Version".
36 The "Minimal Corresponding Source" for a Combined Work means the Corre‐
38 sponding Source for the Combined Work, excluding any source code for
39 portions of the Combined Work that, considered in isolation, are based
40 on the Application, and not on the Linked Version.
41 The "Corresponding Application Code" for a Combined Work means the
43 object code and/or source code for the Application, including any data
44 and utility programs needed for reproducing the Combined Work from the
45 Application, but excluding the System Libraries of the Combined Work.
46
48 You may convey a covered work under sections 3 and 4 of this License
49 without being bound by section 3 of the GNU GPL.
50
52 If you modify a copy of the Library, and, in your modifications, a
53 facility refers to a function or data to be supplied by an Application
54 that uses the facility (other than as an argument passed when the
55 facility is invoked), then you may convey a copy of the modified ver‐
56 sion:
57 a) under this License, provided that you make a good faith effort to
59 ensure that, in the event an Application does not supply the func‐
60 tion or data, the facility still operates, and performs whatever
61 part of its purpose remains meaningful, or
62 b) under the GNU GPL, with none of the additional permissions of this
64 License applicable to that copy.
65
67 The object code form of an Application may incorporate material from a
68 header file that is part of the Library. You may convey such object
69 code under terms of your choice, provided that, if the incorporated
70 material is not limited to numerical parameters, data structure layouts
71 and accessors, or small macros, inline functions and templates (ten or
72 fewer lines in length), you do both of the following:
73 a) Give prominent notice with each copy of the object code that the
75 Library is used in it and that the Library and its use are covered
76 by this License.
77 b) Accompany the object code with a copy of the GNU GPL and this
79 license document.
80
82 You may convey a Combined Work under terms of your choice that, taken
83 together, effectively do not restrict modification of the portions of
84 the Library contained in the Combined Work and reverse engineering for
85 debugging such modifications, if you also do each of the following:
86 a) Give prominent notice with each copy of the Combined Work that the
88 Library is used in it and that the Library and its use are covered
89 by this License.
90 b) Accompany the Combined Work with a copy of the GNU GPL and this
92 license document.
93 c) For a Combined Work that displays copyright notices during execu‐
95 tion, include the copyright notice for the Library among these
96 notices, as well as a reference directing the user to the copies of
97 the GNU GPL and this license document.
98 d)
100 Do one of the following:
101 0) Convey the Minimal Corresponding Source under the terms of this
103 License, and the Corresponding Application Code in a form suit‐
104 able for, and under terms that permit, the user to recombine or
105 relink the Application with a modified version of the Linked
106 Version to produce a modified Combined Work, in the manner
107 specified by section 6 of the GNU GPL for conveying Correspond‐
108 ing Source.
109 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
115 Version.
116 e) Provide Installation Information, but only if you would otherwise
118 be required to provide such information under section 6 of the GNU
119 GPL, and only to the extent that such information is necessary to
120 install and execute a modified version of the Combined Work pro‐
121 duced by recombining or relinking the Application with a modified
122 version of the Linked Version. (If you use option 4d0, the Instal‐
123 lation Information must accompany the Minimal Corresponding Source
124 and Corresponding Application Code. If you use option 4d1, you must
125 provide the Installation Information in the manner specified by
126 section 6 of the GNU GPL for conveying Corresponding Source.)
127
129 You may place library facilities that are a work based on the Library
130 side by side in a single library together with other library facilities
131 that are not Applications and are not covered by this License, and con‐
132 vey such a combined library under terms of your choice, if you do both
133 of the following:
134 a) Accompany the combined library with a copy of the same work based
136 on the Library, uncombined with any other library facilities, con‐
137 veyed under the terms of this License.
138 b) Give prominent notice with the combined library that part of it is
140 a work based on the Library, and explaining where to find the
141 accompanying uncombined form of the same work.
142
144 The Free Software Foundation may publish revised and/or new versions of
145 the GNU Lesser General Public License from time to time. Such new ver‐
146 sions will be similar in spirit to the present version, but may differ
147 in detail to address new problems or concerns.
148 Each version is given a distinguishing version number. If the Library
150 as you received it specifies that a certain numbered version of the GNU
151 Lesser General Public License "or any later version" applies to it, you
152 have the option of following the terms and conditions either of that
153 published version or of any later version published by the Free Soft‐
154 ware Foundation. If the Library as you received it does not specify a
155 version number of the GNU Lesser General Public License, you may choose
156 any version of the GNU Lesser General Public License ever published by
157 the Free Software Foundation.
158 If the Library as you received it specifies that a proxy can decide
160 whether future versions of the GNU Lesser General Public License shall
161 apply, that proxy's public statement of acceptance of any version is
162 permanent authorization for you to choose that version for the Library.
