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) 19yy 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 de-
tails.
The hypothetical commands show w and show c should show the appro-
priate 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) writ-
ten by James Hacker.

sider it more useful to permit linking proprietary applications with the li-
