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.

0. 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.

A “Combined Work” is a work produced by combining or linking an
Application with the Library.

1. 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.

2. Conveying Modified Versions.

If you modify a copy of the Library, and the modifications relate to
a function or data supplied by the Library, you may convey a copy of
the modified version under this License.

3. 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.

4. 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.

5. 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.

6. Revised Versions of the GNU Lesser General Public License.

The Free Software Foundation may publish revised versions of the
GNU Lesser General Public License from time to time.

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.
