1.  Why not just use the existing (:include:) markup which does
    basically the same thing?

2.  But, in order to solve the above, keep in mind that there's
    a *bit* more that has to happen to process the text.  '<', '>',
    and '&' all have to be ampersand-encoded, blank lines have to
    be recognized, and markup processing has to be restarted with
    the first rule (in case the included text has any markups that
    need to be processed by rules already executed).  So, perhaps:

    function QuickTest( $Source )
    {
      # read the page
      $page = ReadPage( "$Source", READPAGE_CURRENT );
      $out  = $page['text'];
      # handle html special chars such as '<', '>', '&'
      $out = htmlspecialchars($out, ENT_NOQUOTES);
      # treat blank lines as <:vspace>
      $out = PVS($out);
      # restart markup rule sequence
      PRR();
      # return new text
      return $out;
    }
