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