Bare-naked Gbrowse render server. Launch with the port number to listen on. No other configuration
information is necessary. The needed configuration will be transmitted from the master server at run
time. If you need to override some configuration information (for example, to specify a different
tmp_base directory for session information), you may place it in a configuration file in the [GENERAL]
section. All options in the [GENERAL] section will override the transmitted information. Any
[name:database] sections containing database information located in the preload config file will be
preloaded to reduce execution latency.
