<p>This version of the GNU Lesser General Public License incorporates


  		




  
  17
  
    
the terms and conditions of version 3 of the GNU General Public

  22
  
    
<p>As used herein, “this License” refers to version 3 of the GNU Lesser


  		




  
  23
  
    
General Public License, and the “GNU GPL” refers to version 3 of the GNU


  		




  
  24
  
    
General Public License.</p>


  		




  
  25
  
    

  		




  
  26
  
    
<p>“The Library” refers to a covered work governed by this License,


  		




  
  27
  
    
other than an Application or a Combined Work as defined below.</p>


  		




  
  28
  
    

  		




  
  29
  
    
<p>An “Application” is any work that makes use of an interface provided


  		




  
  30
  
    
by the Library, but which is not otherwise based on the Library.


  		




  
  31
  
    
Defining a subclass of a class defined by the Library is deemed a mode


  		




  
  32
  
    
of using an interface provided by the Library.</p>


  		




  
  33
  
    

  		




  
  34
  
    
<p>A “Combined Work” is a work produced by combining or linking an


  		




  
  35
  
    
Application with the Library.  The particular version of the Library


  		




  
  36
  
    
with which the Combined Work was made is also called the “Linked


  		




  
  37
  
    
Version”.</p>


  		




  
  38
  
    

  		




  
  39
  
    
<p>The “Minimal Corresponding Source” for a Combined Work means the


  		




  
  40
  
    
Corresponding Source for the Combined Work, excluding any source code


  		




  
  41
  
    
for portions of the Combined Work that, considered in isolation, are


  		




  
  42
  
    
based on the Application, and not on the Linked Version.</p>


  		




  
  43
  
    

  		




  
  44
  
    
<p>The “Corresponding Application Code” for a Combined Work means the


  		




  
  45
  
    
object code and/or source code for the Application, including any data


  		




  
  46
  
    
and utility programs needed for reproducing the Combined Work from the


  		




  
  47
  
    
Application, but excluding the System Libraries of the Combined Work.</p>

<h4><a name="section1"></a>1. Exception to Section 3 of the GNU GPL.</h4>


  		




  
  50
  
    

  		




  
  51
  
    
<p>You may convey a covered work under sections 3 and 4 of this License


  		




  
  52
  
    
without being bound by section 3 of the GNU GPL.</p>

<h4><a name="section2"></a>2. Conveying Modified Versions.</h4>


  		




  
  55
  
    

  		




  
  56
  
    
<p>If you modify a copy of the Library, and, in your modifications, a


  		




  
  57
  
    
facility refers to a function or data to be supplied by an Application


  		




  
  58
  
    
that uses the facility (other than as an argument passed when the


  		




  
  59
  
    
facility is invoked), then you may convey a copy of the modified


  		




  
  60
  
    
version:</p>


  		




  
  61
  
    

  		




  
  62
  
    
<ul>


  		




  
  63
  
    
<li>a) under this License, provided that you make a good faith effort to


  		




  
  64
  
    
   ensure that, in the event an Application does not supply the


  		




  
  65
  
    
   function or data, the facility still operates, and performs


  		




  
  66
  
    
   whatever part of its purpose remains meaningful, or</li>


  		




  
  67
  
    

  		




  
  68
  
    
<li>b) under the GNU GPL, with none of the additional permissions of


  		




  
  69
  
    
   this License applicable to that copy.</li>

<h4><a name="section3"></a>3. Object Code Incorporating Material from Library Header Files.</h4>


  		




  
  73
  
    

  		




  
  74
  
    
<p>The object code form of an Application may incorporate material from


  		




  
  75
  
    
a header file that is part of the Library.  You may convey such object


  		




  
  76
  
    
code under terms of your choice, provided that, if the incorporated


  		




  
  77
  
    
material is not limited to numerical parameters, data structure


  		




  
  78
  
    
layouts and accessors, or small macros, inline functions and templates


  		




  
  79
  
    
(ten or fewer lines in length), you do both of the following:</p>


  		




  
  80
  
    

  		




  
  81
  
    
<ul>


  		




  
  82
  
    
<li>a) Give prominent notice with each copy of the object code that the


  		




  
  83
  
    
   Library is used in it and that the Library and its use are


  		




  
  84
  
    
   covered by this License.</li>


  		




  
  85
  
    

  		




  
  86
  
    
<li>b) Accompany the object code with a copy of the GNU GPL and this license


  		




  
  87
  
    
   document.</li>


  		




  
  88
  
    
</ul>

<h4><a name="section4"></a>4. Combined Works.</h4>


  		




  
  91
  
    

  		




  
  92
  
    
<p>You may convey a Combined Work under terms of your choice that,


  		




  
  93
  
    
taken together, effectively do not restrict modification of the


  		




  
  94
  
    
portions of the Library contained in the Combined Work and reverse


  		




  
  95
  
    
engineering for debugging such modifications, if you also do each of


  		




  
  96
  
    
the following:</p>


  		




  
  97
  
    

  		




  
  98
  
    
<ul>


  		




  
  99
  
    
<li>a) Give prominent notice with each copy of the Combined Work that


  		




  
  100
  
    
   the Library is used in it and that the Library and its use are


  		




  
  101
  
    
   covered by this License.</li>


  		




  
  102
  
    

  		




  
  103
  
    
<li>b) Accompany the Combined Work with a copy of the GNU GPL and this license


  		




  
  104
  
    
   document.</li>


  		




  
  105
  
    

  		




  
  106
  
    
<li>c) For a Combined Work that displays copyright notices during


  		




  
  107
  
    
   execution, include the copyright notice for the Library among


  		




  
  108
  
    
   these notices, as well as a reference directing the user to the


  		




  
  109
  
    
   copies of the GNU GPL and this license document.</li>


  		




  
  110
  
    

  		




  
  111
  
    
<li>d) Do one of the following:


  		




  
  112
  
    

  		




  
  113
  
    
<ul>


  		




  
  114
  
    
<li>0) Convey the Minimal Corresponding Source under the terms of this


  		




  
  115
  
    
       License, and the Corresponding Application Code in a form


  		




  
  116
  
    
       suitable for, and under terms that permit, the user to


  		




  
  117
  
    
       recombine or relink the Application with a modified version of


  		




  
  118
  
    
       the Linked Version to produce a modified Combined Work, in the


  		




  
  119
  
    
       manner specified by section 6 of the GNU GPL for conveying


  		




  
  120
  
    
       Corresponding Source.</li>


  		




  
  121
  
    

  		




  
  122
  
    
<li>1) Use a suitable shared library mechanism for linking with the


  		




  
  123
  
    
       Library.  A suitable mechanism is one that (a) uses at run time


  		




  
  124
  
    
       a copy of the Library already present on the user's computer


  		




  
  125
  
    
       system, and (b) will operate properly with a modified version


  		




  
  126
  
    
       of the Library that is interface-compatible with the Linked


  		




  
  127
  
    
       Version.</li>


  		




  
  128
  
    
</ul></li>


  		




  
  129
  
    

  		




  
  130
  
    
<li>e) Provide Installation Information, but only if you would otherwise


  		




  
  131
  
    
   be required to provide such information under section 6 of the


  		




  
  132
  
    
   GNU GPL, and only to the extent that such information is


  		




  
  133
  
    
   necessary to install and execute a modified version of the


  		




  
  134
  
    
   Combined Work produced by recombining or relinking the


  		




  
  135
  
    
   Application with a modified version of the Linked Version. (If


  		




  
  136
  
    
   you use option 4d0, the Installation Information must accompany


  		




  
  137
  
    
   the Minimal Corresponding Source and Corresponding Application


  		




  
  138
  
    
   Code. If you use option 4d1, you must provide the Installation


  		




  
  139
  
    
   Information in the manner specified by section 6 of the GNU GPL


  		




  
  140
  
    
   for conveying Corresponding Source.)</li>


  		




  
  141

<h4><a name="section5"></a>5. Combined Libraries.</h4>


  		




  
  144
  
    

  		




  
  145
  
    
<p>You may place library facilities that are a work based on the


  		




  
  146
  
    
Library side by side in a single library together with other library


  		




  
  147
  
    
facilities that are not Applications and are not covered by this


  		




  
  148
  
    
License, and convey such a combined library under terms of your


  		




  
  149
  
    
choice, if you do both of the following:</p>


  		




  
  150
  
    

  		




  
  151
  
    
<ul>


  		




  
  152
  
    
<li>a) Accompany the combined library with a copy of the same work based


  		




  
  153
  
    
   on the Library, uncombined with any other library facilities,


  		




  
  154
  
    
   conveyed under the terms of this License.</li>


  		




  
  155
  
    

  		




  
  156
  
    
<li>b) Give prominent notice with the combined library that part of it


  		




  
  157
  
    
   is a work based on the Library, and explaining where to find the


  		




  
  158
  
    
   accompanying uncombined form of the same work.</li>


  		




  
  159
  
    
</ul>

<h4><a name="section6"></a>6. Revised Versions of the GNU Lesser General Public License.</h4>


  		




  
  162
  
    

  		




  
  163
  
    
<p>The Free Software Foundation may publish revised and/or new versions


  		




  
  164
  
    
of the GNU Lesser General Public License from time to time. Such new


  		




  
  165
  
    
versions will be similar in spirit to the present version, but may


  		




  
  166
  
    
differ in detail to address new problems or concerns.</p>


  		




  
  167
  
    

  		




  
  168
  
    
<p>Each version is given a distinguishing version number. If the


  		




  
  169
  
    
Library as you received it specifies that a certain numbered version


  		




  
  170
  
    
of the GNU Lesser General Public License “or any later version”


  		




  
  171
  
    
applies to it, you have the option of following the terms and


  		




  
  172
  
    
conditions either of that published version or of any later version


  		




  
  173
  
    
published by the Free Software Foundation. If the Library as you


  		




  
  174
  
    
received it does not specify a version number of the GNU Lesser


  		




  
  175
  
    
General Public License, you may choose any version of the GNU Lesser


  		




  
  176
  
    
General Public License ever published by the Free Software Foundation.</p>


  		




  
  177
  
    

  		




  
  178
  
    
<p>If the Library as you received it specifies that a proxy can decide


  		




  
  179
  
    
whether future versions of the GNU Lesser General Public License shall


  		




  
  180
  
    
apply, that proxy's public statement of acceptance of any version is


  		




  
  181
  
    
permanent authorization for you to choose that version for the


  		




  
  182
  
    
Library.</p>
