Where can I download/buy Flash CS6 motion presets?

http://www.greensock.com - The only tween library I use. It's awesome.

I dont see any "flash" category. How do i install greensock in flash?

for tweenlite:  on the upper right is a download the appropriate (hopefully, as3) version: http://www.greensock.com/tweenlite/

for tweenmax: on the upper right is a download the appropriate (hopefully, as3) version: http://www.greensock.com/tweenmax/

p.s. these aren't motion presets. they are tweening classes with eases like easein, easeout, bounce, elastic etc.  those eases are also available with the standard flash tween class.
