+This "routerconsole" application runs on top of a trimmed down <a href="jetty.mortbay.com/jetty/index.html">Jetty</a>
+instance (trimmed down, as in, we do not include the demo apps or other add-ons), allowing you to deploy standard 
+JSP/Servlet web applications into your router.  Jetty in turn makes use of Apache's javax.servlet (javax.servlet.jar)
+implementation, as well as their xerces-j XML parser (xerces.jar).  Their XML parser requires the Sun XML
+APIs (JAXP) which is included in binary form (xml-apis.jar) as required by their binary code license.
+This product includes software developed by the Apache Software Foundation (http://www.apache.org/).  See the
+<a href="http://www.i2p.net/">I2P</a> site or the source for more license details.
