1 GNU LESSER GENERAL PUBLIC LICENSE 2 Version 3, 29 June 2007 3 4 Copyright (C) 1992-2015 by Bruce Korb - all rights reserved 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 10the terms and conditions of version 3 of the GNU General Public 11License, 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 16General Public License, and the "GNU GPL" refers to version 3 of the GNU 17General Public License. 18 19 "The Library" refers to a covered work governed by this License, 20other than an Application or a Combined Work as defined below. 21 22 An "Application" is any work that makes use of an interface provided 23by the Library, but which is not otherwise based on the Library. 24Defining a subclass of a class defined by the Library is deemed a mode 25of using an interface provided by the Library. 26 27 A "Combined Work" is a work produced by combining or linking an 28Application with the Library. The particular version of the Library 29with which the Combined Work was made is also called the "Linked 30Version". 31 32 The "Minimal Corresponding Source" for a Combined Work means the 33Corresponding Source for the Combined Work, excluding any source code 34for portions of the Combined Work that, considered in isolation, are 35based on the Application, and not on the Linked Version. 36 37 The "Corresponding Application Code" for a Combined Work means the 38object code and/or source code for the Application, including any data 39and utility programs needed for reproducing the Combined Work from the 40Application, 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 45without 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 50facility refers to a function or data to be supplied by an Application 51that uses the facility (other than as an argument passed when the 52facility is invoked), then you may convey a copy of the modified 53version: 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 66a header file that is part of the Library. You may convey such object 67code under terms of your choice, provided that, if the incorporated 68material is not limited to numerical parameters, data structure 69layouts 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, 82taken together, effectively do not restrict modification of the 83portions of the Library contained in the Combined Work and reverse 84engineering for debugging such modifications, if you also do each of 85the 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 131Library side by side in a single library together with other library 132facilities that are not Applications and are not covered by this 133License, and convey such a combined library under terms of your 134choice, 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 147of the GNU Lesser General Public License from time to time. Such new 148versions will be similar in spirit to the present version, but may 149differ in detail to address new problems or concerns. 150 151 Each version is given a distinguishing version number. If the 152Library as you received it specifies that a certain numbered version 153of the GNU Lesser General Public License "or any later version" 154applies to it, you have the option of following the terms and 155conditions either of that published version or of any later version 156published by the Free Software Foundation. If the Library as you 157received it does not specify a version number of the GNU Lesser 158General Public License, you may choose any version of the GNU Lesser 159General Public License ever published by the Free Software Foundation. 160 161 If the Library as you received it specifies that a proxy can decide 162whether future versions of the GNU Lesser General Public License shall 163apply, that proxy's public statement of acceptance of any version is 164permanent authorization for you to choose that version for the 165Library. 166
