+  Important Notes for Rotation Curves:\n
+  For the rotation IpoCurves, the y values for points are in units of 10 degrees.  example:  45.0 degrees is stored as 4.50 degrees.  These are the same numbers you see in the Transform Properties pupmenu ( NKey ) in the IPO Curve Editor window.  Positive rotations are in a counter-clockwise direction, just like in math class.
