GNU LESSER GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>

Everyone is permitted to copy and distribute verbatim copies of this

licensedocument, 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 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.
