# 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. Let me know if you have any questions or
comments <yaya@yps.org>

Do not take this example into production "as is" 
because it is not secure. If a user start adding "../" to 
the selectdir command it can wander across your whole 
drive.
