With a Wordpress theme, it is necessary to add information to the top of the style.css file:
e.g; for the default theme there is this:
/*
Theme Name: WordPress Default
Theme URI: http://wordpress.org/
Description: The default WordPress theme based on the famous <a href="http://binarybonsai.com/kubrick/">Kubrick</a>.
Version: 1.6
Author: Michael Heilemann
Author URI: http://binarybonsai.com/
Tags: blue, custom header, fixed width, two columns, widgets
*/
Are there any wordpress functions to get this information programatically?
