class Haml::HTML

Converts HTML documents into Haml templates. Depends on [Hpricot](github.com/whymirror/hpricot) for HTML parsing. If ERB conversion is being used, also depends on [Erubis](www.kuwata-lab.com/erubis) to parse the ERB and [ruby_parser](parsetree.rubyforge.org/) to parse the Ruby code.

Example usage:

Haml::HTML.new("<a href='http://google.com'>Blat</a>").render
  #=> "%a{:href => 'http://google.com'} Blat"
