    Quick-start guide:

    * See the Fuseki documentation for instructions on using an in-memory database:
      http://jena.apache.org/documentation/serving_data/#fuseki-server-starting-with-an-empty-dataset

    * Running from the LaunchAgent is different the standard configuration and
      uses traditional Unix paths: please inspect the settings here first:
      #{etc}/fuseki.ttl

      NOTE: Currently the logging configuration file will be overwritten
            if you re-install or upgrade Fuseki. This file is located here:
            #{etc}/'fuseki.log4j.properties'
