 Tidy is an extension based on Libtidy (http://tidy.sf.net/) and allows
 a PHP developer to clean, repair, and traverse HTML, XHTML, and XML
 documents -- including ones with embedded scripting languages such as PHP
 or ASP within them using OO constructs.

 PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used
 open source general-purpose scripting language that is especially suited
 for web development and can be embedded into HTML.
