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]

DESCRIPTION
       Penetrate simulates the arcade classic with the cities and
       the stuff shooting down from the sky and stuff.  The  com-
       puter  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 pro-
       gresses.  Better aim, more economical with ammo, and  bet-
       ter 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.

       -install
               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

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

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

       -foreground color
               Specifies the default foreground color.

       -background color
               Specifies the default background color.

       -bgrowth integer
               Specifies the growth rate of the bomb  explosions.

       -lrate integer
               Set the initial rate of laser fire.

       -smart  Have  the  computer  player skip the learning pro-
               cess.

BUGS
       The layout of the screen isn't quite the same as the  game
       this  program tries to emulate.  In this this program, the
       missles 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.
