|
9 | This version of the GNU Lesser General Public License incorporates
|
10 | the terms and conditions of version 3 of the GNU General Public
|
11 | License, supplemented by the additional permissions listed below.
|
12 |
|
13 | 0. Additional Definitions.
|
14 |
|
15 | As used herein, "this License" refers to version 3 of the GNU Lesser
|
16 | General Public License, and the "GNU GPL" refers to version 3 of the GNU
|
17 | General Public License.
|
18 |
|
19 | "The Library" refers to a covered work governed by this License,
|
20 | other than an Application or a Combined Work as defined below.
|
21 |
|
22 | An "Application" is any work that makes use of an interface provided
|
23 | by the Library, but which is not otherwise based on the Library.
|
24 | Defining a subclass of a class defined by the Library is deemed a mode
|
25 | of using an interface provided by the Library.
|
26 |
|
27 | A "Combined Work" is a work produced by combining or linking an
|
28 | Application with the Library. The particular version of the Library
|
29 | with which the Combined Work was made is also called the "Linked
|
30 | Version".
|
31 |
|
32 | The "Minimal Corresponding Source" for a Combined Work means the
|
33 | Corresponding Source for the Combined Work, excluding any source code
|
34 | for portions of the Combined Work that, considered in isolation, are
|
35 | based on the Application, and not on the Linked Version.
|
36 |
|
37 | The "Corresponding Application Code" for a Combined Work means the
|
38 | object code and/or source code for the Application, including any data
|
39 | and utility programs needed for reproducing the Combined Work from the
|
40 | Application, but excluding the System Libraries of the Combined Work.
|
41 |
|
42 | 1. Exception to Section 3 of the GNU GPL.
|
43 |
|
44 | You may convey a covered work under sections 3 and 4 of this License
|
45 | without being bound by section 3 of the GNU GPL.
|
46 |
|
47 | 2. Conveying Modified Versions.
|
48 |
|
49 | If you modify a copy of the Library, and, in your modifications, a
|
50 | facility refers to a function or data to be supplied by an Application
|
51 | that uses the facility (other than as an argument passed when the
|
52 | facility is invoked), then you may convey a copy of the modified
|
53 | version:
|
54 |
|
55 | a) under this License, provided that you make a good faith effort to
|
56 | ensure that, in the event an Application does not supply the
|
57 | function or data, the facility still operates, and performs
|
58 | whatever part of its purpose remains meaningful, or
|
59 |
|
60 | b) under the GNU GPL, with none of the additional permissions of
|
61 | this License applicable to that copy.
|
62 |
|
63 | 3. Object Code Incorporating Material from Library Header Files.
|
64 |
|
65 | The object code form of an Application may incorporate material from
|
66 | a header file that is part of the Library. You may convey such object
|
67 | code under terms of your choice, provided that, if the incorporated
|
68 | material is not limited to numerical parameters, data structure
|
69 | layouts and accessors, or small macros, inline functions and templates
|
70 | (ten or fewer lines in length), you do both of the following:
|
71 |
|
72 | a) Give prominent notice with each copy of the object code that the
|
73 | Library is used in it and that the Library and its use are
|
74 | covered by this License.
|
75 |
|
76 | b) Accompany the object code with a copy of the GNU GPL and this license
|
77 | document.
|
78 |
|
79 | 4. Combined Works.
|
80 |
|
81 | You may convey a Combined Work under terms of your choice that,
|
82 | taken together, effectively do not restrict modification of the
|
83 | portions of the Library contained in the Combined Work and reverse
|
84 | engineering for debugging such modifications, if you also do each of
|
85 | the following:
|
86 |
|
87 | a) Give prominent notice with each copy of the Combined Work that
|
88 | the Library is used in it and that the Library and its use are
|
89 | covered by this License.
|
90 |
|
91 | b) Accompany the Combined Work with a copy of the GNU GPL and this license
|
92 | document.
|
93 |
|
94 | c) For a Combined Work that displays copyright notices during
|
95 | execution, include the copyright notice for the Library among
|
96 | these notices, as well as a reference directing the user to the
|
97 | copies of the GNU GPL and this license document.
|
98 |
|
99 | d) Do one of the following:
|
100 |
|
101 | 0) Convey the Minimal Corresponding Source under the terms of this
|
102 | License, and the Corresponding Application Code in a form
|
103 | suitable for, and under terms that permit, the user to
|
104 | recombine or relink the Application with a modified version of
|
105 | the Linked Version to produce a modified Combined Work, in the
|
106 | manner specified by section 6 of the GNU GPL for conveying
|
107 | Corresponding Source.
|
108 |
|
109 | 1) Use a suitable shared library mechanism for linking with the
|
110 | Library. A suitable mechanism is one that (a) uses at run time
|
111 | a copy of the Library already present on the user's computer
|
112 | system, and (b) will operate properly with a modified version
|
113 | of the Library that is interface-compatible with the Linked
|
114 | Version.
|
115 |
|
116 | e) Provide Installation Information, but only if you would otherwise
|
117 | be required to provide such information under section 6 of the
|
118 | GNU GPL, and only to the extent that such information is
|
119 | necessary to install and execute a modified version of the
|
120 | Combined Work produced by recombining or relinking the
|
121 | Application with a modified version of the Linked Version. (If
|
122 | you use option 4d0, the Installation Information must accompany
|
123 | the Minimal Corresponding Source and Corresponding Application
|
124 | Code. If you use option 4d1, you must provide the Installation
|
125 | Information in the manner specified by section 6 of the GNU GPL
|
126 | for conveying Corresponding Source.)
|
127 |
|
128 | 5. Combined Libraries.
|
129 |
|
130 | You may place library facilities that are a work based on the
|
131 | Library side by side in a single library together with other library
|
132 | facilities that are not Applications and are not covered by this
|
133 | License, and convey such a combined library under terms of your
|
134 | choice, if you do both of the following:
|
135 |
|
136 | a) Accompany the combined library with a copy of the same work based
|
137 | on the Library, uncombined with any other library facilities,
|
138 | conveyed under the terms of this License.
|
139 |
|
140 | b) Give prominent notice with the combined library that part of it
|
141 | is a work based on the Library, and explaining where to find the
|
142 | accompanying uncombined form of the same work.
|
143 |
|
144 | 6. Revised Versions of the GNU Lesser General Public License.
|
145 |
|
146 | The Free Software Foundation may publish revised and/or new versions
|
147 | of the GNU Lesser General Public License from time to time. Such new
|
148 | versions will be similar in spirit to the present version, but may
|
149 | differ in detail to address new problems or concerns.
|
150 |
|
151 | Each version is given a distinguishing version number. If the
|
152 | Library as you received it specifies that a certain numbered version
|
153 | of the GNU Lesser General Public License "or any later version"
|
154 | applies to it, you have the option of following the terms and
|
155 | conditions either of that published version or of any later version
|
156 | published by the Free Software Foundation. If the Library as you
|
157 | received it does not specify a version number of the GNU Lesser
|
158 | General Public License, you may choose any version of the GNU Lesser
|
159 | General Public License ever published by the Free Software Foundation.
|
160 |
|
161 | If the Library as you received it specifies that a proxy can decide
|
162 | whether future versions of the GNU Lesser General Public License shall
|
163 | apply, that proxy's public statement of acceptance of any version is
|
164 | permanent authorization for you to choose that version for the
|
165 | Library.
