SYNOPSISpenetrate [-display host:display.screen] [-root] [-window]
[-install] [-noinstall] [-visual visual] [-bgrowth

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.

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.
