GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation,
Inc.
51 Franklin Street, Fifth Floor, Boston, MA
02110-1301 USA
Everyone is permitted to copy and distribute
verbatim copies
of this license document, but changing it is not
allowed.
[This is the first released version of the Lesser GPL. It
also counts
as the successor of the GNU Library Public License,
version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take
away your
freedom to share and change it. By contrast, the
GNU General Public
Licenses are intended to guarantee your freedom to
share and change
free software--to make sure the software is free for
all its users.
This license, the Lesser General Public License,
applies to some
specially designated software packages--typically
libraries--of the
Free Software Foundation and other authors who
decide to use it. You
can use it too, but we suggest you first think carefully
about whether
this license or the ordinary General Public License is
the better
strategy to use in any particular case, based on the
explanations below.
When we speak of free software, we are referring to
freedom of use,
not price. Our General Public Licenses are designed
to make sure that
you have the freedom to distribute copies of free
software (and charge
for this service if you wish); that you receive source
code or can get
it if you want it; that you can change the software and
use pieces of
it in new free programs; and that you are informed
that you can do
these things.
To protect your rights, we need to make restrictions
that forbid
distributors to deny you these rights or to ask you to
surrender these
rights. These restrictions translate to certain
responsibilities for
you if you distribute copies of the library or if you
modify it.
For example, if you distribute copies of the library,
whether gratis
or for a fee, you must give the recipients all the rights
that we gave
you. You must make sure that they, too, receive or
can get the source
code. If you link other code with the library, you
must provide
complete object files to the recipients, so that they
can relink them
with the library after making changes to the library
and recompiling
it. And you must show them these terms so they
know their rights.
We protect your rights with a two-step method: (1)
we copyright the
library, and (2) we offer you this license, which gives
you legal
permission to copy, distribute and/or modify the
library.
To protect each distributor, we want to make it very
clear that
there is no warranty for the free library. Also, if the
library is
modified by someone else and passed on, the
recipients should know
that what they have is not the original version, so that
the original
author's reputation will not be affected by problems
that might be
introduced by others.
