=head1 DESCRIPTION
The B<dump> function writes the contents of an B<RRD> in human
manipulate the contents of an B<RRD> file in a somewhat more
convenient manner.

=over 8
=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<--no-header>|B<-n>
+=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>.
-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.
+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. 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.
+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.
