GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
0. This License Agreement applies to any software library which contains a notice placed by the
copyright holder or other authorized party saying it may be distributed under the terms of this
Library General Public License (also called “this License”). Each licensee is addressed as “you”.
A “library” means a collection of software functions and/or data prepared so as to be conveniently
linked with application programs (which use some of those functions and data) to form executables.
The “Library”, below, refers to any such software library or work which has been distributed under
these terms. A “work based on the Library” means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with
modifications and/or translated straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term “modification.)
“Source code” for a work means the preferred form of the work for making modifications to it. For a
library, complete source code means all the source code for all modules it contains, plus any associa-
ted interface definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope.
The act of running a program using the Library is not restricted, and output from such a program is
covered only if its contents constitute a work based on the Library (independent of the use of the
Library in a tool for writing it). Whether that is true depends on what the Library does and what the
program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library’s complete source code as you recei-
ve it, in any medium, provided that you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and distribute a copy of this License along with
the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based
on the Library, and copy and distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files
and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the
terms of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an
application program that uses the facility, other than as an argument passed when the facility is
invoked, then you must make a good faith effort to ensure that, in the event an application does
not supply such function or table, the facility still operates, and performs whatever part of its
purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely well-de-
fined independent of the application. Therefore, Subsection 2d requires that any application-supplied
function or table used by this function must be optional: if the application does not supply it, the
square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Library, and can be reasonably considered independent and separate works
in themselves, then this License, and its terms, do not apply to those sections when you distribute
them as separate works. But when you distribute the same sections as part of a whole which is a
work based on the Library, the distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to each and every part regardless
of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely
by you; rather, the intent is to exercise the right to control the distribution of derivative or collective
works based on the Library.
