Apache Module using the Tidy Library to Clean Up HTML, XHTML, and XML

mod_tidy is a module for Apache that works as a filter that hooks
itself to HTML output.	mod_tidy feeds the HTML output to TidyLib
(http://tidy.sourceforge.net/), which validates the HTML output.  If
TidyLib finds an error, the client receives a HTML page with a list of
all found errors. If TidyLib does not complain, you get your HTML data
as without mod_tidy.

To load the module into Apache, run the command "a2enmod tidy" as root.

To learn about the configuration, refer to
/usr/share/doc/packages/apache2-mod_tidy/README.
