I am trying to copy a site with lots of files. It is using
the directory browsing function of a web server and it gives
me pages with heading so I can sort the page on file name,
file size, file date etc.

The problem is that every page generates several index.html
files, each one corresponding to a different sort option.
This is generating a lot of overhead and unnecessary files
since I am only interested in the meat, ie., the files in
the directories.

How can I avoid this?
