This module has been shamelessly ripped off from Sam Streeper's SpaxeWar module.  Due to the brilliantly modular way he wrote it (and the power of NeXTSTEP!), it was easy for me to add computer players.   Otherwise, the game is the same.

The object of the game is to annihilate your opponent before he gets you.  In XoxWar (as oppposed to SpaxeWar), the opponent may be a computer instead of another human!  The popup lists select the type of computer player. 

"Commander" means no computer player - the human is in complete control.  
"CrazyMander" involves random movement
"TrackMander" attempts to match velocity then fire on you.

In addition, the difficulty switch controls how often the computer player can move, and hence how hard it is to fight him.  Other than that, the computer players are "fair" - they are not stronger or weaker than the human players.

You can set zero, one, or two computer players.  The human controls are always accepted, although they may be overriden by the computer.  You can of course choose to play either side:

The blue player's controls are:
z - rotate left
x - rotate right
(comma) - thrust
(period) - fire
(space) - shields

The red player's controls (on the keypad) are:
1 - rotate left
2 - rotate right
6 - thrust
9 - fire
(enter) - shields
