  message: <<EOM
1) This port does not install any doom .wad ,
so you have to download it and run prboom -iwad /path/to/doom.wad
or put it in /usr/local/share/games/doom/ !

2) Prboom is very out of date (http://prboom.sourceforge.net), so
if you like prboom and  want a newer version
you should look at http://prboom-plus.sourceforge.net!

3)Have fun!
EOM
