/**
* Servlet that enables remote management of the web applications deployed
* within the same virtual host as this web application is.  Normally, this
* functionality will be protected by a security constraint in the web
* application deployment descriptor.  However, this requirement can be
* relaxed during testing.
* 

* The difference between the ManagerServlet and this * Servlet is that this Servlet prints out a HTML interface which * makes it easier to administrate. *

* However if you use a software that parses the output of * ManagerServlet you won't be able to upgrade * to this Servlet since the output are not in the * same format ar from ManagerServlet * * @author Bip Thelin * @author Malcolm Edgar * @author Glenn L.
