+/**
+ * TMarkdown class
+ *
+ * TMarkdown is a control that produces HTML from code with markdown syntax.
+ *
+ * Markdown is a text-to-HTML conversion tool for web writers. Markdown allows
+ * you to write using an easy-to-read, easy-to-write plain text format, then
+ * convert it to structurally valid XHTML (or HTML).
+ * Further documentation regarding Markdown can be found at
+ * http://daringfireball.net/projects/markdown/
+ *
+ * To use TMarkdown, simply enclose the content to be rendered within
+ * the body of TMarkdown in a template.
+ *
+ * See http://www.pradosoft.com/demos/quickstart/?page=Markdown for
+ * details on the Markdown syntax usage.
