[Pharo-users] Simplifying a File reference

[Prof. Andrew P. Black]

I have a file reference containing multiple occurrences of .., like this

File @ 
/Users/black/graceProgs/lists/../../Development/mg/gracelang/albums_junk.grace

How do I simplify this to show the simpler path without the .. ?  There should 
be a method on FileReference, no?  Something like #normalize ?  Or maybe 
FileReference should do this automatically when it is created?
