 There is some extra magic in this document besides the usual DocBook semantics
 to allow us to derive manpages, HTML and usage messages from the same source 
 document.

 Examples need to be moved to the end for man pages. To this end, <para>s and
 <screen>s with role="example" will be moved, and with role="example-prefix" 
 will be removed.

 The usage messages are more involved. We have some magic in usage.xsl to pull
 out the command synopsis, global option and subcommand synopses. We also pull
 out <para>s with role="usage".

 Finally we construct lists of possible values for subcommand options, if the 
 subcommand's <varlistentry> has role="usage-has-option-list". The option which
 takes the values should be marked with role="usage-option-list".

    <title>Description</title>
    <para>
      RabbitMQ is an implementation of AMQP, the emerging standard for high
      performance enterprise messaging. The RabbitMQ server is a robust and
      scalable implementation of an AMQP broker.
    </para>
    <para>
      <command>rabbitmqctl</command> is a command line tool for managing a
      RabbitMQ broker. It performs all actions by connecting to one of the
      broker's nodes.

              The RabbitMQ broker will attempt to append the current contents
              of the log file to the file with name composed of the original
              name and the suffix.
              It will create a new file if such a file does not already exist.
              When no <option>suffix</option> is specified, the empty log file is

              Instruct the node to become member of a cluster with the

            </para>
            <para>
              Cluster nodes can be of two types: disk or ram. Disk nodes
              replicate data in ram and on disk, thus providing
              redundancy in the event of node failure and recovery from
              global events such as power failure across all nodes. Ram
              nodes replicate data in ram only and are mainly used for
              scalability. A cluster must always have at least one disk node.
            </para>
            <para>
              If the current node is to become a disk node it needs to
              appear in the cluster node list. Otherwise it becomes a
              ram node. If the node list is empty or only contains the
              current node then the node becomes a standalone,
              i.e. non-clustered, (disk) node.
            </para>
            <para>
              After executing the <command>cluster</command> command, whenever
              the RabbitMQ application is started on the current node it
              will attempt to connect to the specified nodes, thus
              becoming an active node in the cluster comprising those
              nodes (and possibly others).
            </para>
            <para>
              The list of nodes does not have to contain all the
              cluster's nodes; a subset is sufficient. Also, clustering
              generally succeeds as long as at least one of the
              specified nodes is active. Hence adjustments to the list
              are only necessary if the cluster configuration is to be
              altered radically.
            </para>
            <para>
              For this command to succeed the RabbitMQ application must
              have been stopped, e.g. with <link linkend="stop_app"><command>stop_app</command></link>. Furthermore,
              turning a standalone node into a clustered node requires
              the node be <link linkend="reset"><command>reset</command></link> first,
              in order to avoid accidental destruction of data with the
