How do I import a library in flash which lies in a higher directory than my .fla
I have a directory structure as follows:

    Projects ->
	Libraries ->
		Box2d ->
			Collision->
			Common ->
			etc...
	PlaneGame ->
		PlaneGame.fla
		main.as

Now I wish to import classes from Box2d but I cannot figure out how to do "up one level" which would be done like "../../something.example" in another language.

How can I include classes from inside the Box2d folder?
