           SSSSppppaaaacccceeee is two-person game of firing missiles at each other.
           In turn, each player enters a missile launch angle (in the
           range 0 to 360), and a launch velocity (in the range 0 to
           10).

           Each trajectory is plotted on the display.  With each turn,
           the players fine-tune their angles and velocities until one
           player blows up the other's spaceship.

           With each prompt for a trajectory or velocity, the system
           prints the player's previous input as a reminder.  To re-
           confirm that previous value, without re-entering the number
           by hand, just press [RETURN].

           Velocities and angles may contain decimal fractions, such as
           33334444....6666.  Both spaceships use the same method of calculating
           angles.  Zero degrees is the the right, 90 degrees is
           straight up, 180 degrees is to the left, and 270 degrees is
           straight down.
