+Only generate the graph if the current graph is out of date or not existent.
+Note, that all the calculations will happen regardless so that the output of
+PRINT and graphv will be complete regardless. Note that the behavior of
+lazy in this regard has seen several changes over time. The only thing you

+graph when it is already there and up to date, and also that it will output
+the size of the graph.

+Address of the L<rrdcached> daemon. If specified, a C<flush> command is sent
+to the server before reading the RRD files. This allows the graph to contain
+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.
