If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) [year]
[name of author]
Gnomovision comes with ABSOLUTELY NO WARRANTY;
for details type ‘show w’. This is free software, and you are welcome to redistribute it under certain
conditions; type ‘show c’ for details.
The hypothetical commands ‘show w’ and ‘show c’ should show the appropriate parts of the General
Public License. Of course, the commands you use m
ay 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.

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
