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.

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
