1 | GNU LESSER GENERAL PUBLIC LICENSE | ||||
---|---|---|---|---|---|

3 | | ||||
4 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> | ||||
5 | Everyone is permitted to copy and distribute verbatim copies | ||||
6 | of this license document, but changing it is not allowed. | ||||

8 | | ||||
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. |
