Plugin Name: Textile 2
Version: 2.0 Beta
Plugin URI: http://www.huddledmasses.org/
Description: This is a simple wrapper for <a href="http://textism.com/?wp">Dean Allen's</a> Humane Web Text Generator, also known as <a href="http://www.textism.com/tools/textile/">Textile</a>. Version 2 adds a lot of flexibility that makes it almost a HTML meta-language. As a cost, it's slower. If you use this plugin you should disable Textile 1 and Markdown, as they don't play well together.
