* script will be parsed by Text_Wiki.  This differs from the 'embed'
* rule, which incorporates the results at render-time, meaning that the
* 'embed' content is not parsed by Text_Wiki.
*
* DANGER!
* 
* This rule is inherently not secure; it allows cross-site scripting to
* occur if the embedded output has <script> or other similar tags.  Be
* careful.
