GNU LESSER GENERAL PUBLIC LICENSE
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
1. Additional Definitions.
^^^^^^^^^^^^^^^^^^^^^^^^^^
As used herein, “this License” refers to version 3 of the GNU
Lesser General Public License, and the “GNU GPL” refers to version
3 of the GNU General Public License.
“The Library” refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An “Application” is any work that makes use of an interface
provided by the Library, but which is not otherwise based on the
Library. Defining a subclass of a class defined by the Library is
deemed a mode of using an interface provided by the Library.
A “Combined Work” is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the “Linked Version”.
The “Minimal Corresponding Source” for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The “Corresponding Application Code” for a Combined Work means the
object code and/or source code for the Application, including any
data and utility programs needed for reproducing the Combined Work
from the Application, but excluding the System Libraries of the
Combined Work.
2. Exception to Section 3 of the GNU GPL.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
3. Conveying Modified Versions.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you modify a copy of the Library, and, in your modifications,
a facility refers to a function or data to be supplied by an
Application that uses the facility (other than as an argument passed
when the facility is invoked), then you may convey a copy of the
modified version:
a) under this License, provided that you make a good faith effort
to ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
4. Object Code Incorporating Material from Library Header Files.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and
templates (ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this
license document.
5. Combined Works.
^^^^^^^^^^^^^^^^^^^
You may convey a Combined Work under terms of your choice that, taken
together, effectively do not restrict modification of the portions of
the Library contained in the Combined Work and reverse engineering
for debugging such modifications, if you also do each of the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this
license document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of
this License, and the Corresponding Application Code in a
form suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version
of the Linked Version to produce a modified Combined Work,
in the manner specified by section 6 of the GNU GPL for
conveying Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run
time a copy of the Library already present on the user's
computer system, and (b) will operate properly with a
modified version of the Library that is interface-compatible
with the Linked Version.
e) Provide Installation Information, but only if you would
otherwise be required to provide such information under section
6 of the GNU GPL, and only to the extent that such information
is necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
6. Combined Libraries.
^^^^^^^^^^^^^^^^^^^^^^
You may place library facilities that are a work based on the Library
side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities, conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
7. Revised Versions of the GNU Lesser General Public License.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
as you received it specifies that a certain numbered version of the
GNU Lesser General Public License “or any later version” applies to
it, you have the option of following the terms and conditions either
of that published version or of any later version published by the
Free Software Foundation. If the Library as you received it does not
specify a version number of the GNU Lesser General Public License,
you may choose any version of the GNU Lesser General Public License
ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License
shall apply, that proxy's public statement of acceptance of any
version is permanent authorization for you to choose that version for
the Library.
