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. 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.
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, 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.
3. Object Code Incorporating Material from Library Header Files.
