  23  * 
  24  * This class implements a Text_Wiki_Rule to embed the contents of a URL
  25  * inside the page at render-time.  Typically used to get script output.
  26  * This differs from the 'include' rule, which incorporates results at
  27  * parse-time; 'embed' output does not get parsed by Text_Wiki, while
  28  * 'include' ouput does.
  29  *
  30  * This rule is inherently not secure; it allows cross-site scripting to
  31  * occur if the embedded output has <script> or other similar tags.  Be
  32  * careful.
