Gnomovision comes with ABSOLUTELY NO
WARRANTY; for details type `show w'. This is
free software, and you are welcome to redistri-
bute it under certain conditions; type `show c'
for details.
The hypothetical commands `show w' and `show
c' should show the appropriate parts of the Gene-
ral 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 neces-
sary.
Here is a sample; alter the names:

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.

Everyone is permitted to copy and distribute ver-
batim copies of this license document, but chan-

It also counts as the successor of the GNU Library

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 stra-
tegy 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
library or if you modify it.
