Use: GRAVITY4 [SimulationFile.SIM]

Examples: 
  GRAVITY4 STARX.SIM
  GRAVITY4 SOLARSYS.SIM
  GRAVITY4 EARTHSUN.SIM

Control View Keys: 

	E,X,S,D	- move view up,down,left,right
	T,V	- zoom in/out
	I,M	- speed up/slow down simulation
	<,>	- change view center on a different object
	F	- fit simulation to the screen
	ESC	- exit

Please Note that if simulation is centered on an object,
you can only zoom in/out, you cannot move the view, as
it will stay centered.

Look at the included .SIM files in a text editor.
The file format is explained within it, and you
can create your own simulations from it!

If you create any interesting .SIM simulations, please
email them to me and I will include them on my webpage.
Please maintain the file format, as I have, so others
can understand what the simulation is simulating.

Please note that the engine does NOT support
collisions, and close encounters which are OUT
OF RANGE of the computation model.  This usually results
in the two masses shot at a very high velocity in either
direction.  This is not what would really happen.
The engine cannot handle such extreme situations.
