      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.  |
