Is there a list somewhere that gives examples of all the cases that one has
to handle when dealing with symlinks? Ideal would be a shell script that
creats a small directory tree with examples of all the cases. Symlink
handling
seems to me to be a lot easier than this discussion makes it sound, so I
suspect
I'm completely overlooking some major difficult case.
