0. This License Agreement applies to any softwar
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the ter
this Lesser 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 pr
(which use some of those functions and data) to form executables.
The “Library”, below
has been distributed under these terms. A “work based on the Librar
means either the Library or any derivative work under copyright law:
that is to say
verbatim or with modifications and/or translated straightforwardly into
another language. (Hereinafter
in the term “modification”.)
“Source code” for a work means the pr
making modifications to it. For a library
all the source code for all modules it contains, plus any associated
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 Librar
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 r
conspicuously and appropriately publish on each copy an appr
copyright notice and disclaimer of warranty; keep intact all the notices
that refer to this License and to the absence of any warranty; and

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 perfor
