AcroSpin(TM) can rotate, translate (pan over), and scale (enlarge or shrink)
3-dimensional wire frame objects and point clouds.  This tutorial will help you
learn how to use AcroSpin.  It will display sixteen objects for you to play
with, each preceded by explanatory text.  When you finish with an object, press
the ESC key to exit from AcroSpin; that will return you to this tutorial.

	  THE ESSENTIAL KEYS: R, T, S, AND THE ARROW KEYS

You control the motion of an object by using the keys on your keyboard.
    Hold down an arrow key to rotate, translate, or scale the object.
    Press and release R, and then the arrow keys will rotate the object.
    Press and release T, and then the arrow keys will translate the object.
    Press and release S, and then the arrow keys will scale the object.
AcroSpin doesn't care if you type R, T, or S in uppercase or lowercase.  When
you first enter AcroSpin, holding down an arrow key will rotate the object.

You can practice using the R, T, S, and arrow keys on the first object, a cube.
If you want to stop this tutorial, simultaneously hold down the CONTROL and
BREAK keys when it asks you to `Strike a key when ready . . . '. If for some
reason AcroSpin can't run on your system, it will give you an error message
explaining why.
