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. |
