fast -> slow -> stop using actionscript

[buzzby]

i am after a script (lost thru reformat) that allows an animation to start of very fast then slow down then stop as it gets nearer its finishing point. this works well for a shape moving from left to right. it starts off fast then as it gets to its destination is slows down to a halt.

what script is used for this please?
