This package includes Clearsilver, the CGI kit and HTML templating system.

This module attempts to make using HTML templates simple and natural. It extends standard HTML with a few new HTML-esque tags: <TMPL_VAR>, <TMPL_LOOP>, <TMPL_INCLUDE>, <TMPL_IF>, <TMPL_ELSE> and <TMPL_UNLESS>. The file written with HTML and these new tags is called a template. Using this module you fill in the values for the variables, loops and branches declared in the template. This allows you to separate design from the data.
