+RepRapFirmware - Webserver
+
+This class serves a single-page web applications to the attached network.  This page forms the user's 
+interface with the RepRap machine.  This software interprests returned values from the page and uses it
+to Generate G Codes, which it sends to the RepRap.  It also collects values from the RepRap like 
+temperature and uses those to construct the web page.
+
+The page itself - reprap.htm - uses Knockout.js and Jquery.js.  See:
