0001 GNU LESSER GENERAL PUBLIC LICENSE 0002 Version 3, 29 June 2007 0003 0004 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 0005 0006 Everyone is permitted to copy and distribute verbatim copies of this license 0007 document, but changing it is not allowed. 0008 0009 This version of the GNU Lesser General Public License incorporates the terms 0010 and conditions of version 3 of the GNU General Public License, supplemented 0011 by the additional permissions listed below. 0012 0013 0. Additional Definitions. 0014 0015 As used herein, "this License" refers to version 3 of the GNU Lesser General 0016 Public License, and the "GNU GPL" refers to version 3 of the GNU General Public 0017 License. 0018 0019 "The Library" refers to a covered work governed by this License, other than 0020 an Application or a Combined Work as defined below. 0021 0022 An "Application" is any work that makes use of an interface provided by the 0023 Library, but which is not otherwise based on the Library. Defining a subclass 0024 of a class defined by the Library is deemed a mode of using an interface provided 0025 by the Library. 0026 0027 A "Combined Work" is a work produced by combining or linking an Application 0028 with the Library. The particular version of the Library with which the Combined 0029 Work was made is also called the "Linked Version". 0030 0031 The "Minimal Corresponding Source" for a Combined Work means the Corresponding 0032 Source for the Combined Work, excluding any source code for portions of the 0033 Combined Work that, considered in isolation, are based on the Application, 0034 and not on the Linked Version. 0035 0036 The "Corresponding Application Code" for a Combined Work means the object 0037 code and/or source code for the Application, including any data and utility 0038 programs needed for reproducing the Combined Work from the Application, but 0039 excluding the System Libraries of the Combined Work. 0040 0041 1. Exception to Section 3 of the GNU GPL. 0042 You may convey a covered work under sections 3 and 4 of this License without 0043 being bound by section 3 of the GNU GPL. 0044 0045 2. Conveying Modified Versions. 0046 If you modify a copy of the Library, and, in your modifications, a facility 0047 refers to a function or data to be supplied by an Application that uses the 0048 facility (other than as an argument passed when the facility is invoked), 0049 then you may convey a copy of the modified version: 0050 0051 a) under this License, provided that you make a good faith effort to ensure 0052 that, in the event an Application does not supply the function or data, the 0053 facility still operates, and performs whatever part of its purpose remains 0054 meaningful, or 0055 0056 b) under the GNU GPL, with none of the additional permissions of this License 0057 applicable to that copy. 0058 0059 3. Object Code Incorporating Material from Library Header Files. 0060 The object code form of an Application may incorporate material from a header 0061 file that is part of the Library. You may convey such object code under terms 0062 of your choice, provided that, if the incorporated material is not limited 0063 to numerical parameters, data structure layouts and accessors, or small macros, 0064 inline functions and templates (ten or fewer lines in length), you do both 0065 of the following: 0066 0067 a) Give prominent notice with each copy of the object code that the Library 0068 is used in it and that the Library and its use are covered by this License. 0069 0070 b) Accompany the object code with a copy of the GNU GPL and this license document. 0071 0072 4. Combined Works. 0073 You may convey a Combined Work under terms of your choice that, taken together, 0074 effectively do not restrict modification of the portions of the Library contained 0075 in the Combined Work and reverse engineering for debugging such modifications, 0076 if you also do each of the following: 0077 0078 a) Give prominent notice with each copy of the Combined Work that the Library 0079 is used in it and that the Library and its use are covered by this License. 0080 0081 b) Accompany the Combined Work with a copy of the GNU GPL and this license 0082 document. 0083 0084 c) For a Combined Work that displays copyright notices during execution, include 0085 the copyright notice for the Library among these notices, as well as a reference 0086 directing the user to the copies of the GNU GPL and this license document. 0087 0088 d) Do one of the following: 0089 0090 0) Convey the Minimal Corresponding Source under the terms of this License, 0091 and the Corresponding Application Code in a form suitable for, and under terms 0092 that permit, the user to recombine or relink the Application with a modified 0093 version of the Linked Version to produce a modified Combined Work, in the 0094 manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 0095 0096 1) Use a suitable shared library mechanism for linking with the Library. 0097 A suitable mechanism is one that (a) uses at run time a copy of the Library 0098 already present on the user's computer system, and (b) will operate properly 0099 with a modified version of the Library that is interface-compatible with the 0100 Linked Version. 0101 0102 e) Provide Installation Information, but only if you would otherwise be required 0103 to provide such information under section 6 of the GNU GPL, and only to the 0104 extent that such information is necessary to install and execute a modified 0105 version of the Combined Work produced by recombining or relinking the Application 0106 with a modified version of the Linked Version. (If you use option 4d0, the 0107 Installation Information must accompany the Minimal Corresponding Source and 0108 Corresponding Application Code. If you use option 4d1, you must provide the 0109 Installation Information in the manner specified by section 6 of the GNU GPL 0110 for conveying Corresponding Source.) 0111 0112 5. Combined Libraries. 0113 You may place library facilities that are a work based on the Library side 0114 by side in a single library together with other library facilities that are 0115 not Applications and are not covered by this License, and convey such a combined 0116 library under terms of your choice, if you do both of the following: 0117 0118 a) Accompany the combined library with a copy of the same work based on the 0119 Library, uncombined with any other library facilities, conveyed under the 0120 terms of this License. 0121 0122 b) Give prominent notice with the combined library that part of it is a work 0123 based on the Library, and explaining where to find the accompanying uncombined 0124 form of the same work. 0125 0126 6. Revised Versions of the GNU Lesser General Public License. 0127 The Free Software Foundation may publish revised and/or new versions of the 0128 GNU Lesser General Public License from time to time. Such new versions will 0129 be similar in spirit to the present version, but may differ in detail to address 0130 new problems or concerns. 0131 0132 Each version is given a distinguishing version number. If the Library as you 0133 received it specifies that a certain numbered version of the GNU Lesser General 0134 Public License "or any later version" applies to it, you have the option of 0135 following the terms and conditions either of that published version or of 0136 any later version published by the Free Software Foundation. If the Library 0137 as you received it does not specify a version number of the GNU Lesser General 0138 Public License, you may choose any version of the GNU Lesser General Public 0139 License ever published by the Free Software Foundation. 0140 0141 If the Library as you received it specifies that a proxy can decide whether 0142 future versions of the GNU Lesser General Public License shall 0143 apply, that proxy's public statement of acceptance of any version is permanent 0144 authorization for you to choose that version for the Library.
