html file browser

[chadon 0]

I have a script that generates static html files for a forum hosted in a free host that don't accept mod rewrite. This script works perfect but has a bug to display all the html files it created and there is no support or updates from the author.
Can anyone tell me if there is a script that only grabs html files in a directory and subdirectories and displays them in a webpage? I know there is scripts that do that for pictures but I can't find anything for what I want.
