   6  * 
   7  * This class implements a Text_Wiki_Parse to include the results of a
   8  * script directly into the source at parse-time; thus, the output of the
   9  * script will be parsed by Text_Wiki.  This differs from the 'embed'
  10  * rule, which incorporates the results at render-time, meaning that the
  11  * 'embed' content is not parsed by Text_Wiki.
  12  *
  13  * DANGER!
  14  * 
  15  * This rule is inherently not secure; it allows cross-site scripting to
  16  * occur if the embedded output has <script> or other similar tags.  Be
  17  * careful.
