Convert a GameObject to a transform?

 #pragma strict 
 
 //If you want to change tag in inspector. MainCamera is default just for this example.
 var targetTag : String = "MainCamera";
 private var target : Transform;
 
 function Start()
 {
     //Use GameObject.FindWithTag as usual, then reference the GameObject's Transform component.
     target = GameObject.FindWithTag(targetTag).transform;
     print(target.name);
 }
