GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, 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 library GPL. It is
numbered 2 because it goes with version 2 of the
ordinary GPL.]
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 Library General Public License, applies
to some
specially designated Free Software Foundation software,
and to any
other libraries whose authors decide to use it. You can
use it for
your libraries, too.
When we speak of free software, we are referring to
freedom, 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 or use
pieces of it
in new free programs; and that you know you can do
these things.
To protect your rights, we need to make restrictions that
forbid
anyone to deny you these rights or to ask you to
surrender the 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 a program 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.
Our method of protecting your rights has two steps: (1)
copyright
the library, and (2) offer you this license which gives you
legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make
certain
that everyone understands that there is no warranty for
this free
library. If the library is modified by someone else and
passed on, we
want its recipients to know that what they have is not the
original
version, so that any problems introduced by others will
not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by
software
patents. We wish to avoid the danger that companies
distributing free
software will individually obtain patent licenses, thus in
effect
transforming the program into proprietary software. To
prevent this,
we have made it clear that any patent must be licensed
for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered
by the ordinary
GNU General Public License, which was designed for
utility programs. This
license, the GNU Library General Public License, applies
to certain
designated libraries. This license is quite different from
the ordinary
