  <!-- Define the Manager Servlet
       Change servlet-class to: org.apache.catalina.servlets.HTMLManagerServlet
       to get a Servlet with a more intuitive HTML interface, don't change if you
       have software that is expected to parse the output from ManagerServlet
       since they're not compatible.
