  If the program is portable you would have no way to know what the
path delimiter is... since the set includes "/" for UNIX, "\" for
MS-DOS, ":[]" for VMS, ":<>" for TOPS, etc. Since some systems allow
ugly things like "$#_%" in filenames, you are better off not trying to
identify all the possibilities.

  You could put in some conditional code to do things for common
operating systems if you wanted to display the last level of the name,
and if you were being portable you would use strrchr (I don't see rindex
in the ANSI standard, at least in the index or 4.11).
