I feel like the Sorcerer's Apprentice.  (from Walt Disney's "Fantasia")  I
peeked in the source for ln and learned how to make a hard link on a
directory.

Now, I am having a little problem removing it.  ;-)

Okay, I did:
mkdir test test/dir1 test/dir2
cd test/dir1
ln -F ../dir2 dir2shadow

when I do a rm -f or rmdir on either dir2 or dir2shadow, it laughs at me.
More specifically, it says "directory not empty".  Can someone help???
