The hypothetical commands `show w' and `show c' should show the appropriate parts of the General
Public License. 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 Library General Public License
instead of this License.

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
