Same file?

[Jeff Massung]

Is there a nice little way in Rev to check and see if two file paths are the
same? For example:

"../../../Home/jeff/foo.txt"
"/Users/Home/jeff/foo.txt"
"c:\Users\Home\jeff\foo.txt"

These may all actually be the same file. Before I go down the road of
directory traversals, file path separators, and drive name parsing... is
there a way for me to know in Rev if they are the same easily?
