This scriupt will give a very basic file listing with an insecure upload functionality.
Do not use this on a public website, as it is vulnerable to many hack attempts.

Use this script only in secure areas !!! I do not take any responsibility for any damage caused
by the use of this script.

You may alter and freely redistribute this script as long as you let me know by email.
You may NOT remove the footer information without WRITTEN PERMISSION from the author.

If you made alterations to the script, let me know and I will publish you script along with mine,
if you like.

In any case: let me know what you think.
