    # :BindAddress:: Local address for the server to bind to
    # :DocumentRoot:: Root path to serve files from
    # :DocumentRootOptions:: Options for the default HTTPServlet::FileHandler
    # :HTTPVersion:: The HTTP version of this server
    # :Port:: Port to listen on
    # :RequestCallback:: Called with a request and response before each
    #                    request is serviced.
    # :RequestTimeout:: Maximum time to wait between requests
    # :ServerAlias:: Array of alternate names for this server for virtual
    #                hosting
    # :ServerName:: Name for this server for virtual hosting
