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.
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.
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
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.)
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 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.
6. 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
