use may be called something other than `show w'
and `show c'; they could even be mouse-clicks or
menu items – whatever suits your program.
You should also get your employer (if you work as
a programmer) or your school, if any, to sign a
"copyright disclaimer" for the program, if neces-
sary.
Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision' (which
makes passes at compilers) written by James
Hacker.

This General Public License does not permit incor-
porating your program into proprietary programs.
If your program is a subroutine library, you may
consider it more useful to permit linking proprie-
tary applications with the library. If this is what
you want to do, use the GNU Lesser General Public
License instead of this License.

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 Soft-
ware 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 strat-
egy 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 restric-
tions that forbid distributors to deny you these
rights or to ask you to surrender these rights.
These restrictions translate into certain responsi-
bilities for you if you distribute copies of the lib-
rary or if you modify it.
For example, if you distribute copies of the library,
whether gratis or for a fee, you must give the reci-
pients 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 reci-
pients, so that they can relink them with the lib-
rary 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 lib-
rary. 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.
Finally, software patents pose a constant threat to
the existence of any free program. We wish to
make sure that a company cannot effectively
restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore,
we insist that any patent license obtained for a
version of the library must be consistent with the
full freedom of use specified in this license.
Most GNU software, including some libraries, is
covered by the ordinary GNU General Public
License. This license, the GNU Lesser General Pub-
lic License, applies to certain designated libraries,
and is quite different from the ordinary General
Public License. We use this license for certain libra-
ries in order to permit linking those libraries into
non-free programs.
When a program is linked with a library, whether
statically or using a shared library, the combina-
tion of the two is legally speaking a combined
work, a derivative of the original library. The ordi-
