Of course, the commands you 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 necessary. 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 incorporating
your program into proprietary programs. If your program is a
subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what
you want to do, use the GNU Lesser General Public License
instead of this License.
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.
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 Public License, applies to certain designated
libraries, and is quite different from the ordinary General Public
License. We use this license for certain libraries in order to
permit linking those libraries into non-free programs.
