        ElasticMQ is a message queueing system with Java, Scala and
        Amazon SQS-compatible interfaces.  You should set the
        environment ELASTICMQ_DATA_PREFIX to a writable directory
        where ElasticMQ will store its data and log files.  It also
        looks for its configuration file in
        $ELASTICMQ_DATA_PREFIX/conf/Default.scala.  You can use the
        Default.scala included in the distribution as a template.
