3// This function looks for text including markup and
4// applies tidy's repair function to it.
5// Tidy is a HTML clean and
6// repair utility, which is currently available for PHP 4.3.x and PHP 5 as a
7// PECL extension from http://pecl.php.net/package/tidy, in PHP 5 you need only
8// to compile using the --with-tidy option.
9// If you don't have the tidy extension installed or don't know, you can enable
10// or disable this filter, it just won't have any effect.
11// If you want to know what you can set in $tidyoptions and what their default
12// values are, see http://php.net/manual/en/function.tidy-get-config.php.
