+ relativeNameIfAbsoluteFor: aFileName
+ 	"Answer either the relative name for aFileName, if aFileName names a file in me or
+ 	 subdirectories, or aFileName's absolute path if it isn't in me or subdirectories.
+ 	 P.S. Ths is what I'd expect relativeNameFor: to do, but it is taken and means
+ 	 exactly the opposite, i.e. the absolute path for a relative name."
