Mirror a directory structure
Mirror a directory structure
# This code will mirror a directory structure (like /home/ftp/pub, the
anonymous ftp dir) that is headed by the topdir.
# The icons it refere to are those provided by the apache server by default.
These, of course, can be switched to
# whatever you wish.
# This is probably not the most elegant way to do this and the ability to
differentiate between file types could probably
# be added, but it does work.
