 Tasks provided by the sysv init script:
     restart         - stop running instance (if there is one), start new instance
     console         - start broker in foreground, useful for debugging purposes
     status          - check if activemq process is running
     setup           - create the specified configuration file for this init script
                       (see next usage section)

 Configuration of this script:
     The configuration of this script can be placed on /etc/default/activemq or $HOME/.activemqrc.
     To use additional configurations for running multiple instances on the same operating system
     rename or symlink script to a name matching to activemq-instance-<INSTANCENAME>.
     This changes the configuration location to /etc/default/activemq-instance-<INSTANCENAME> and
     \$HOME/.activemqrc-instance-<INSTANCENAME>. Configuration files in /etc have higher precedence.

	Configuration of this script:
	The configuration of this script can be placed on /etc/default/activemq or $HOME/.activemqrc.
	To use additional configurations for running multiple instances on the same operating system
	rename or symlink script to a name matching to activemq-instance-<INSTANCENAME>.
