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 it-
self, 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 pro-
gressively 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.

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.
