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.

   -root   Draw on the root window.

   -window Draw on a newly-created window.  This is the default.

   -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

           default, best, mono, monochrome, gray, grey, color, staticgray,
           staticcolor,  truecolor,  grayscale,  greyscale,   pseudocolor,
           directcolor, number

           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.
