+* If you want to debug something, start the cluster.pl up thus:-
+
+ perl -d cluster.pl
+ dbg> r
+
+ Then you can go into debug mode at anytime by using the command :-
+
+ debug
+
+ or you can put the line:-
+
+ $DB::single = 1;
+
+ in an appropriate place in a command. This will only have an effect
+ if you are running in perl debug mode.
