    restart         - stop running instance (is 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 addtional 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.
