-In rrdtool 1.3, the dump function started producing correct xml-headers.
-Unfortunately the rrdtool restore function from the 1.2 series can not
-handle these headers. With this option you can supress the creatinon of
-the xml headers.
+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.
