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