+=item B<--no-header>|B<-n>
+
+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.
+
+=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. To
+specify a UNIX domain socket use the prefix C<unix:>, see example below. Other
+addresses are interpreted as normal network addresses, i.E<nbsp>e. IPv4 or IPv6
+addresses in most cases.
