=item I<filename.rrd>
The (optional) filename that you want to write the XML output to.
If not specified, the XML will be printed to stdout.
+=item B<--header>|B<-h> {xsd,dtd}
+
+Optionally rrdtool can add a xsd or dtd header to the dump output.
+
+=item B<--daemon> I<address>
+
+Address of the L<rrdcached> daemon. If specified, a C<flush> command is sent
+to the server before reading the RRD files. This allows B<rrdtool> to return
+fresh data even if the daemon is configured to cache values for a long time.
+For a list of accepted formats, see the B<-l> option in the L<rrdcached> manual.
