+=item I<filename.xml>
+
+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> {none,xsd,dtd}
+
+By default rrdtool will add a dtd header to the xml file. Here
+you can customize this to and xsd header or no header at all.
+
+
+=item B<--no-header>
+
+A shortcut for S<--header=none>.
+
+If you want to restore the dump with rrdtool 1.2 you should use the
+S<--no-header> option since 1.2 can not deal with xml headers.
+
+=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.
+
