| 5 | Everyone is permitted to copy and distribute verbatim copies |
| 6 | of this license document, but changing it is not allowed. |

| 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. |
| 166 | |

| 168 | |
| 169 | SPECIAL EXCEPTION GRANTED BY COPYRIGHT HOLDERS |
| 170 | |
| 171 | As a special exception, copyright holders give you permission to link this |
| 172 | library with independent modules to produce an executable, regardless of |
| 173 | the license terms of these independent modules, and to copy and distribute |
| 174 | the resulting executable under terms of your choice, provided that you also |
| 175 | meet, for each linked independent module, the terms and conditions of |
| 176 | the license of that module. An independent module is a module which is not |
| 177 | derived from or based on this library. If you modify this library, you must |
| 178 | extend this exception to your version of the library. |
| 179 | |
| 180 | Note: this exception relieves you of any obligations under sections 4 and 5 |
| 181 | of this license, and section 6 of the GNU General Public License. |
