242 | salvo | 1 | GNU LESSER GENERAL PUBLIC LICENSE |
2 | Version 3, 29 June 2007 |
||
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. |
||
7 | |||
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. |
