INTRODUCTION
  This program is loosely based on a BASIC program from  "The big fat Book of
  Computer Games"  by Tim Hartnell, 1984.

  This program was written in Turbo Pascal v.5.

AIM
  This is a simple "Aliens attacking Earth" game.  Your objective is to RAM
  all the (defenceless) Alien ships before they can land on Earth;  while
  doing this you must avoid the alien Droids which will try to RAM you!

PLAY
  The game is played on a representation of near Earth space.  The Aliens
  start on the left of screen, Earth is on the right and you are in the middle.
  To complicate matters, there are stationary mines which will blow up ships
  if hit, and moving "meteors" which destroy anything they hit!

  The game logic is very simple but the skill levels (1-9) allow the game to
  be sped up to considerably increase the level of difficulty.

MOVEMENT
  Two sets of movement keys can be used:

   1) on the keyboard main section:

     A (up)
     |
     Z (down)      < (left) -- > (right)

   2) on the numeric keypad:

                   8/up arrow (up)
                          |
   4/left arrow (left)  --+--    6/right arrow (right)
                          |
                 2/down arrow (down)

LEGEND
  The (text) characters below represent the objects in the game:
     A   Alien ships (your targets)
     D   Alien droids
     *   stationary mines
     þ   meteors
