	You almost always want $@, at least in my experience.  But you also
need to quote it, like this:

	for FILE in "$@"
	do
		foo "$FILE"
	done

That will iterate across each file name even if it contains spaces.  The
"$*" version will split "words" at the spaces, and that's almost
certainly NOT what you want.

	HTH!
