nuclear@2 1 GNU LESSER GENERAL PUBLIC LICENSE
nuclear@2 2 Version 3, 29 June 2007
nuclear@2 3
nuclear@2 4 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
nuclear@2 5 Everyone is permitted to copy and distribute verbatim copies
nuclear@2 6 of this license document, but changing it is not allowed.
nuclear@2 7
nuclear@2 8
nuclear@2 9 This version of the GNU Lesser General Public License incorporates
nuclear@2 10 the terms and conditions of version 3 of the GNU General Public
nuclear@2 11 License, supplemented by the additional permissions listed below.
nuclear@2 12
nuclear@2 13 0. Additional Definitions.
nuclear@2 14
nuclear@2 15 As used herein, "this License" refers to version 3 of the GNU Lesser
nuclear@2 16 General Public License, and the "GNU GPL" refers to version 3 of the GNU
nuclear@2 17 General Public License.
nuclear@2 18
nuclear@2 19 "The Library" refers to a covered work governed by this License,
nuclear@2 20 other than an Application or a Combined Work as defined below.
nuclear@2 21
nuclear@2 22 An "Application" is any work that makes use of an interface provided
nuclear@2 23 by the Library, but which is not otherwise based on the Library.
nuclear@2 24 Defining a subclass of a class defined by the Library is deemed a mode
nuclear@2 25 of using an interface provided by the Library.
nuclear@2 26
nuclear@2 27 A "Combined Work" is a work produced by combining or linking an
nuclear@2 28 Application with the Library. The particular version of the Library
nuclear@2 29 with which the Combined Work was made is also called the "Linked
nuclear@2 30 Version".
nuclear@2 31
nuclear@2 32 The "Minimal Corresponding Source" for a Combined Work means the
nuclear@2 33 Corresponding Source for the Combined Work, excluding any source code
nuclear@2 34 for portions of the Combined Work that, considered in isolation, are
nuclear@2 35 based on the Application, and not on the Linked Version.
nuclear@2 36
nuclear@2 37 The "Corresponding Application Code" for a Combined Work means the
nuclear@2 38 object code and/or source code for the Application, including any data
nuclear@2 39 and utility programs needed for reproducing the Combined Work from the
nuclear@2 40 Application, but excluding the System Libraries of the Combined Work.
nuclear@2 41
nuclear@2 42 1. Exception to Section 3 of the GNU GPL.
nuclear@2 43
nuclear@2 44 You may convey a covered work under sections 3 and 4 of this License
nuclear@2 45 without being bound by section 3 of the GNU GPL.
nuclear@2 46
nuclear@2 47 2. Conveying Modified Versions.
nuclear@2 48
nuclear@2 49 If you modify a copy of the Library, and, in your modifications, a
nuclear@2 50 facility refers to a function or data to be supplied by an Application
nuclear@2 51 that uses the facility (other than as an argument passed when the
nuclear@2 52 facility is invoked), then you may convey a copy of the modified
nuclear@2 53 version:
nuclear@2 54
nuclear@2 55 a) under this License, provided that you make a good faith effort to
nuclear@2 56 ensure that, in the event an Application does not supply the
nuclear@2 57 function or data, the facility still operates, and performs
nuclear@2 58 whatever part of its purpose remains meaningful, or
nuclear@2 59
nuclear@2 60 b) under the GNU GPL, with none of the additional permissions of
nuclear@2 61 this License applicable to that copy.
nuclear@2 62
nuclear@2 63 3. Object Code Incorporating Material from Library Header Files.
nuclear@2 64
nuclear@2 65 The object code form of an Application may incorporate material from
nuclear@2 66 a header file that is part of the Library. You may convey such object
nuclear@2 67 code under terms of your choice, provided that, if the incorporated
nuclear@2 68 material is not limited to numerical parameters, data structure
nuclear@2 69 layouts and accessors, or small macros, inline functions and templates
nuclear@2 70 (ten or fewer lines in length), you do both of the following:
nuclear@2 71
nuclear@2 72 a) Give prominent notice with each copy of the object code that the
nuclear@2 73 Library is used in it and that the Library and its use are
nuclear@2 74 covered by this License.
nuclear@2 75
nuclear@2 76 b) Accompany the object code with a copy of the GNU GPL and this license
nuclear@2 77 document.
nuclear@2 78
nuclear@2 79 4. Combined Works.
nuclear@2 80
nuclear@2 81 You may convey a Combined Work under terms of your choice that,
nuclear@2 82 taken together, effectively do not restrict modification of the
nuclear@2 83 portions of the Library contained in the Combined Work and reverse
nuclear@2 84 engineering for debugging such modifications, if you also do each of
nuclear@2 85 the following:
nuclear@2 86
nuclear@2 87 a) Give prominent notice with each copy of the Combined Work that
nuclear@2 88 the Library is used in it and that the Library and its use are
nuclear@2 89 covered by this License.
nuclear@2 90
nuclear@2 91 b) Accompany the Combined Work with a copy of the GNU GPL and this license
nuclear@2 92 document.
nuclear@2 93
nuclear@2 94 c) For a Combined Work that displays copyright notices during
nuclear@2 95 execution, include the copyright notice for the Library among
nuclear@2 96 these notices, as well as a reference directing the user to the
nuclear@2 97 copies of the GNU GPL and this license document.
nuclear@2 98
nuclear@2 99 d) Do one of the following:
nuclear@2 100
nuclear@2 101 0) Convey the Minimal Corresponding Source under the terms of this
nuclear@2 102 License, and the Corresponding Application Code in a form
nuclear@2 103 suitable for, and under terms that permit, the user to
nuclear@2 104 recombine or relink the Application with a modified version of
nuclear@2 105 the Linked Version to produce a modified Combined Work, in the
nuclear@2 106 manner specified by section 6 of the GNU GPL for conveying
nuclear@2 107 Corresponding Source.
nuclear@2 108
nuclear@2 109 1) Use a suitable shared library mechanism for linking with the
nuclear@2 110 Library. A suitable mechanism is one that (a) uses at run time
nuclear@2 111 a copy of the Library already present on the user's computer
nuclear@2 112 system, and (b) will operate properly with a modified version
nuclear@2 113 of the Library that is interface-compatible with the Linked
nuclear@2 114 Version.
nuclear@2 115
nuclear@2 116 e) Provide Installation Information, but only if you would otherwise
nuclear@2 117 be required to provide such information under section 6 of the
nuclear@2 118 GNU GPL, and only to the extent that such information is
nuclear@2 119 necessary to install and execute a modified version of the
nuclear@2 120 Combined Work produced by recombining or relinking the
nuclear@2 121 Application with a modified version of the Linked Version. (If
nuclear@2 122 you use option 4d0, the Installation Information must accompany
nuclear@2 123 the Minimal Corresponding Source and Corresponding Application
nuclear@2 124 Code. If you use option 4d1, you must provide the Installation
nuclear@2 125 Information in the manner specified by section 6 of the GNU GPL
nuclear@2 126 for conveying Corresponding Source.)
nuclear@2 127
nuclear@2 128 5. Combined Libraries.
nuclear@2 129
nuclear@2 130 You may place library facilities that are a work based on the
nuclear@2 131 Library side by side in a single library together with other library
nuclear@2 132 facilities that are not Applications and are not covered by this
nuclear@2 133 License, and convey such a combined library under terms of your
nuclear@2 134 choice, if you do both of the following:
nuclear@2 135
nuclear@2 136 a) Accompany the combined library with a copy of the same work based
nuclear@2 137 on the Library, uncombined with any other library facilities,
nuclear@2 138 conveyed under the terms of this License.
nuclear@2 139
nuclear@2 140 b) Give prominent notice with the combined library that part of it
nuclear@2 141 is a work based on the Library, and explaining where to find the
nuclear@2 142 accompanying uncombined form of the same work.
nuclear@2 143
nuclear@2 144 6. Revised Versions of the GNU Lesser General Public License.
nuclear@2 145
nuclear@2 146 The Free Software Foundation may publish revised and/or new versions
nuclear@2 147 of the GNU Lesser General Public License from time to time. Such new
nuclear@2 148 versions will be similar in spirit to the present version, but may
nuclear@2 149 differ in detail to address new problems or concerns.
nuclear@2 150
nuclear@2 151 Each version is given a distinguishing version number. If the
nuclear@2 152 Library as you received it specifies that a certain numbered version
nuclear@2 153 of the GNU Lesser General Public License "or any later version"
nuclear@2 154 applies to it, you have the option of following the terms and
nuclear@2 155 conditions either of that published version or of any later version
nuclear@2 156 published by the Free Software Foundation. If the Library as you
nuclear@2 157 received it does not specify a version number of the GNU Lesser
nuclear@2 158 General Public License, you may choose any version of the GNU Lesser
nuclear@2 159 General Public License ever published by the Free Software Foundation.
nuclear@2 160
nuclear@2 161 If the Library as you received it specifies that a proxy can decide
nuclear@2 162 whether future versions of the GNU Lesser General Public License shall
nuclear@2 163 apply, that proxy's public statement of acceptance of any version is
nuclear@2 164 permanent authorization for you to choose that version for the
nuclear@2 165 Library.
