Everyone is permitted to copy and distribute verbatim copies |

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. |
