Pardon the not-very-useful wild guess, but wasn't there a nice example program in some old Camel Book that would print out an output like

  /home/mjd/foo.c
  /home/mjd/bar/baz/foo.c
  /home/mjd/bar-1.0/baz/foo.c
  /userhomes/m/j/mjd/bar-1.0/baz/foo.c
  /mnt/homevol/m/j/mjd/bar-1.0/baz/foo.c
[download]

as it progressively resolved the symlinks in higher and higher components of a path?

I thought it might have been one of those abandoned items in the Perl source eg/ directory, but I couldn't find it there, so the Camel Book was my next guess.

Addendum: This looks kinda interesting too.
