   7  * This class implements a Text_Wiki_Parse to embed the contents of a URL
   8  * inside the page.  Typically used to get script output.
   9  *
  10  * This rule is inherently not secure; it allows cross-site scripting to
  11  * occur if the embedded output has <script> or other similar tags.  Be
  12  * careful.
  13  *
  14  * In the future, we'll add a rule config options to set the base embed
  15  * path so that it is limited to one directory.
