   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.
