[wplug] tidy bash script

[ARiley at edgarsnyder.com]

I am using HTML Tidy to clean html pages that I have downloaded locally.
The configuration options and error file parameters are handled by a file I
created called tidy.conf.

I wrote a script that calls that file and works fine except that it can not
traverse up and down the directories of pages - causing me to run the
script manually in each directory.  My bash is weak.  Does anyone know how
to descend into directories and climb back out?

#!/bin/bash
conf="-config /etc/tidy.conf"

for file in *.html;
  do tidy $conf $file
done
