Emptying a movie clip holder

programming flash
1

I’ve been using a Movieclip as a holder for other movie clips:

var iconHolder:MovieClip = new MovieClip();
addChild (iconHolder);

Then . . .

iconHolder.addChild (icon1);
iconHolder.addChild (icon2); etc.

I’d like to empty this iconHolder Movieclip when I reset the game. Is there an easy way to do this?
Thanks!
