Need help converting AS 2 rollover effect to AS 3!

I am having trouble with a piece of code that I used to implement for all of my buttons in Actionscript 2.0. What I need help with is creating a similar effect in AS 3 (see code at bottom of post).

I prefer this code because when a visitor rolls off of the button before it is finished with the rollover animation, it will rewind the animation and give it a smooth rollout effect (instead of an abrupt stop to the rollover effect to play the roll out effect).

Any help is appreciated, thanks!


this.onEnterFrame = function(){
     if (rewind == true){
          prevFrame();
     }
}

this.onRollOver = function(){
     rewind = false;
     play();
}

this.onRollOut = function(){
     rewind = true;
}

this.onRelease = function(){
     getURL("index.html");
}

My timeline would be setup like this: I set up the rollover effect only, putting stop(); code in the keyframe at the beginning and end of animation. Because of the rewind (prevFrame()) effect it would use the same animation to rewind for the rollout effect.
