GNU LESSER GENERAL PUBLIC LICENSE | |
Version 3, 29 June 2007 | |
Copyright (C) 2007 Free Software Foundation, Inc. <https://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. | |
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. |
