/**
6 
*
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.
