=head1 HOW IT WORKS
Causes the daemon to start flushing ALL pending values to disk. This
returns immediately, even though the writes may take a long time.
+=item B<PENDING> I<filename>

+Shows any "pending" updates for a file, in order. The updates shown have
+not yet been written to the underlying RRD file.

=item B<HELP> [I<command>]
Returns a short usage message. If no command is given, or I<command> is
for, so describing the mechanism again is unnecessary. Read L<HOW IT WORKS>
above for a detailed explanation.
+Note that rrdcached only accepts absolute timestamps in the update values.
+Updates strings like "N:1:2:3" are automatically converted to absolute
+time by the RRD client library before sending to rrdcached.
