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.

OPTIONS

       -display host:display.screen
               Specifies which X display we should use.

               Install a private colormap for the window.

       -noinstall
               Don't install a private colormap for the window.

       -visual visual
               Specify  which  visual  to use.  Legal values are the name of a
               visual class, or the id number (decimal or hex) of  a  specific
               visual.  Possible choices include

               If  a decimal or hexadecimal number is used, XGetVisualInfo(3X)
               is consulted to obtain the required visual.

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.
