Tweenlite is a very useful tween engine that you should familiarize yourself with and learn to love. It's part of the very powerful Greensock ActionScript library.
If you download the AS3 version, you'll see the greensock.swc file. This is a compiled version of the Classes available in the com folder.
In order to add the SWC file to your project (instead of adding the com folder) you go to: File->Publish Settings and in the Flash tab you select Settings. Click the + button and insert ./greensock.swc (assuming it's in the same folder as the FLA):


Click "OK" and "OK".
The Greensock library is now available in your FLA.

You may have noticed the use of the TweenLite Class in the reposition() method:, .4, { x:x0, y:y0 } );

This slides the object by tweening its x and y positions from the current position to x0 and y0 (initial position), taking .4 seconds to get there.

This Class has endless possibilities, but fading objects in and out always looks good, an has never been so easy, so here's an example:

my_mc.alpha = 0;, .5, { alpha: 1 } ); // fading in

// these two lines are the same as
TweenLite.from(my_mc, .5, { alpha: 0 } ); // fading in
