/**
6 
*
7 
* This class implements a Text_Wiki_Parse to embed the contents of a URL
8 
* inside the page at render-time.  Typically used to get script output.
9 
* This differs from the 'include' rule, which incorporates results at
10 
* parse-time; 'embed' output does not get parsed by Text_Wiki, while
11 
* 'include' ouput does.
12 
*
13 
* This rule is inherently not secure; it allows cross-site scripting to
14 
* occur if the embedded output has <script> or other similar tags.  Be
15 
* careful.
