| 3 | # GNU LESSER GENERAL PUBLIC LICENSE |
| 4 | # Version 3, 29 June 2007 |
| 5 | # |
| 6 | # Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
| 7 | # Everyone is permitted to copy and distribute verbatim copies |
| 8 | # of this license document, but changing it is not allowed. |
| 9 | # |
| 10 | # |
| 11 | # This version of the GNU Lesser General Public License incorporates |
| 12 | # the terms and conditions of version 3 of the GNU General Public |
| 13 | # License, supplemented by the additional permissions listed below. |
| 14 | # |
| 15 | # 0. Additional Definitions. |
| 16 | # |
| 17 | # As used herein, "this License" refers to version 3 of the GNU Lesser |
| 18 | # General Public License, and the "GNU GPL" refers to version 3 of the GNU |
| 19 | # General Public License. |
| 20 | # |
| 21 | # "The Library" refers to a covered work governed by this License, |
| 22 | # other than an Application or a Combined Work as defined below. |
| 23 | # |
| 24 | # An "Application" is any work that makes use of an interface provided |
| 25 | # by the Library, but which is not otherwise based on the Library. |
| 26 | # Defining a subclass of a class defined by the Library is deemed a mode |
| 27 | # of using an interface provided by the Library. |
| 28 | # |
| 29 | # A "Combined Work" is a work produced by combining or linking an |
| 30 | # Application with the Library. The particular version of the Library |
| 31 | # with which the Combined Work was made is also called the "Linked |
| 32 | # Version". |
| 33 | # |
| 34 | # The "Minimal Corresponding Source" for a Combined Work means the |
| 35 | # Corresponding Source for the Combined Work, excluding any source code |
| 36 | # for portions of the Combined Work that, considered in isolation, are |
| 37 | # based on the Application, and not on the Linked Version. |
| 38 | # |
| 39 | # The "Corresponding Application Code" for a Combined Work means the |
| 40 | # object code and/or source code for the Application, including any data |
| 41 | # and utility programs needed for reproducing the Combined Work from the |
| 42 | # Application, but excluding the System Libraries of the Combined Work. |
| 43 | # |
| 44 | # 1. Exception to Section 3 of the GNU GPL. |
| 45 | # |
| 46 | # You may convey a covered work under sections 3 and 4 of this License |
| 47 | # without being bound by section 3 of the GNU GPL. |
| 48 | # |
| 49 | # 2. Conveying Modified Versions. |
| 50 | # |
| 51 | # If you modify a copy of the Library, and, in your modifications, a |
| 52 | # facility refers to a function or data to be supplied by an Application |
| 53 | # that uses the facility (other than as an argument passed when the |
| 54 | # facility is invoked), then you may convey a copy of the modified |
| 55 | # version: |
| 56 | # |
| 57 | # a) under this License, provided that you make a good faith effort to |
| 58 | # ensure that, in the event an Application does not supply the |
| 59 | # function or data, the facility still operates, and performs |
| 60 | # whatever part of its purpose remains meaningful, or |
| 61 | # |
| 62 | # b) under the GNU GPL, with none of the additional permissions of |
| 63 | # this License applicable to that copy. |
| 64 | # |
| 65 | # 3. Object Code Incorporating Material from Library Header Files. |
| 66 | # |
| 67 | # The object code form of an Application may incorporate material from |
| 68 | # a header file that is part of the Library. You may convey such object |
| 69 | # code under terms of your choice, provided that, if the incorporated |
| 70 | # material is not limited to numerical parameters, data structure |
| 71 | # layouts and accessors, or small macros, inline functions and templates |
| 72 | # (ten or fewer lines in length), you do both of the following: |
| 73 | # |
| 74 | # a) Give prominent notice with each copy of the object code that the |
| 75 | # Library is used in it and that the Library and its use are |
| 76 | # covered by this License. |
| 77 | # |
| 78 | # b) Accompany the object code with a copy of the GNU GPL and this license |
| 79 | # document. |
| 80 | # |
| 81 | # 4. Combined Works. |
| 82 | # |
| 83 | # You may convey a Combined Work under terms of your choice that, |
| 84 | # taken together, effectively do not restrict modification of the |
| 85 | # portions of the Library contained in the Combined Work and reverse |
| 86 | # engineering for debugging such modifications, if you also do each of |
| 87 | # the following: |
| 88 | # |
| 89 | # a) Give prominent notice with each copy of the Combined Work that |
| 90 | # the Library is used in it and that the Library and its use are |
| 91 | # covered by this License. |
| 92 | # |
| 93 | # b) Accompany the Combined Work with a copy of the GNU GPL and this license |
| 94 | # document. |
| 95 | # |
| 96 | # c) For a Combined Work that displays copyright notices during |
| 97 | # execution, include the copyright notice for the Library among |
| 98 | # these notices, as well as a reference directing the user to the |
| 99 | # copies of the GNU GPL and this license document. |
| 100 | # |
| 101 | # d) Do one of the following: |
| 102 | # |
| 103 | # 0) Convey the Minimal Corresponding Source under the terms of this |
| 104 | # License, and the Corresponding Application Code in a form |
| 105 | # suitable for, and under terms that permit, the user to |
| 106 | # recombine or relink the Application with a modified version of |
| 107 | # the Linked Version to produce a modified Combined Work, in the |
| 108 | # manner specified by section 6 of the GNU GPL for conveying |
| 109 | # Corresponding Source. |
| 110 | # |
| 111 | # 1) Use a suitable shared library mechanism for linking with the |
| 112 | # Library. A suitable mechanism is one that (a) uses at run time |
| 113 | # a copy of the Library already present on the user's computer |
| 114 | # system, and (b) will operate properly with a modified version |
| 115 | # of the Library that is interface-compatible with the Linked |
| 116 | # Version. |
| 117 | # |
| 118 | # e) Provide Installation Information, but only if you would otherwise |
| 119 | # be required to provide such information under section 6 of the |
| 120 | # GNU GPL, and only to the extent that such information is |
| 121 | # necessary to install and execute a modified version of the |
| 122 | # Combined Work produced by recombining or relinking the |
| 123 | # Application with a modified version of the Linked Version. (If |
| 124 | # you use option 4d0, the Installation Information must accompany |
| 125 | # the Minimal Corresponding Source and Corresponding Application |
| 126 | # Code. If you use option 4d1, you must provide the Installation |
| 127 | # Information in the manner specified by section 6 of the GNU GPL |
| 128 | # for conveying Corresponding Source.) |
| 129 | # |
| 130 | # 5. Combined Libraries. |
| 131 | # |
| 132 | # You may place library facilities that are a work based on the |
| 133 | # Library side by side in a single library together with other library |
| 134 | # facilities that are not Applications and are not covered by this |
| 135 | # License, and convey such a combined library under terms of your |
| 136 | # choice, if you do both of the following: |
| 137 | # |
| 138 | # a) Accompany the combined library with a copy of the same work based |
| 139 | # on the Library, uncombined with any other library facilities, |
| 140 | # conveyed under the terms of this License. |
| 141 | # |
| 142 | # b) Give prominent notice with the combined library that part of it |
| 143 | # is a work based on the Library, and explaining where to find the |
| 144 | # accompanying uncombined form of the same work. |
| 145 | # |
| 146 | # 6. Revised Versions of the GNU Lesser General Public License. |
| 147 | # |
| 148 | # The Free Software Foundation may publish revised and/or new versions |
| 149 | # of the GNU Lesser General Public License from time to time. Such new |
| 150 | # versions will be similar in spirit to the present version, but may |
| 151 | # differ in detail to address new problems or concerns. |
| 152 | # |
| 153 | # Each version is given a distinguishing version number. If the |
| 154 | # Library as you received it specifies that a certain numbered version |
| 155 | # of the GNU Lesser General Public License "or any later version" |
| 156 | # applies to it, you have the option of following the terms and |
| 157 | # conditions either of that published version or of any later version |
| 158 | # published by the Free Software Foundation. If the Library as you |
| 159 | # received it does not specify a version number of the GNU Lesser |
| 160 | # General Public License, you may choose any version of the GNU Lesser |
| 161 | # General Public License ever published by the Free Software Foundation. |
| 162 | # |
| 163 | # If the Library as you received it specifies that a proxy can decide |
| 164 | # whether future versions of the GNU Lesser General Public License shall |
| 165 | # apply, that proxy's public statement of acceptance of any version is |
| 166 | # permanent authorization for you to choose that version for the |
| 167 | # Library. |
