NAME

       penetrate - simulates a classic arcade shooting game

SYNOPSIS

       penetrate  [-display  host:display.screen]  [-root]  [-window]  [-install]  [-noinstall] [-visual visual]
       [-bgrowth microseconds] [-lrate number] [-smart number] [-fps]

DESCRIPTION

       Penetrate simulates the arcade classic with the cities and the stuff  shooting  down  from  the  sky  and
       stuff.   The  computer  plays  against  itself,  desperately  defending  the forces of good against those
       thingies raining down.  Bonus cities are awarded at ever-increasing intervals.  Every five levels appears
       a bonus round.  The computer player gets progressively more intelligent as the game  progresses.   Better
       aim,  more  economical  with ammo, and better target selection.  Points are in the bottom right, and high
       score is in the bottom left.  Start with -smart to have the computer player skip the learning process.

               Specifies which X display we should use.

BUGS

       The  layout  of  the screen isn't quite the same as the game this program tries to emulate.  In this this
       program, the missiles come out of the cities; when really, there are supposed to be three  missile  bases
       on hills, with the cities in the valleys between them.
