/**
* Servlet that enables remote management of the web applications deployed

* functionality will be protected by a security constraint in the web
* application deployment descriptor.  However, this requirement can be
* relaxed during testing.
* <p>
* The difference between the <code>ManagerServlet</code> and this
* Servlet is that this Servlet prints out a HTML interface which
* makes it easier to administrate.
* <p>
* However if you use a software that parses the output of
* <code>ManagerServlet</code you won't be able to upgrade
* to this Servlet since the output are not in the
* same format ar from <code>ManagerServlet</code>
