# Even this can be confused, look what happens if user joe

# Now user bill makes a symbolic link from his public_html/bar
# ~joe/public_html/foo.  This directory now has two URLs,
# http://some.server/~joe/foo/ and http://some.server/~bill/bar/ .
# The name that we generate is foo, which is only half right :-(
