    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: Fuseki uses 1) log4j.configuration if defined, 2) 'log4j.properties' file if exists,
      or built-in configuration. See also:
      https://issues.apache.org/jira/browse/JENA-536
