- * 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.
