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.␊ |
