+* As this is perl and it is very easy to alter stuff to get it correct,
+ I would like to see some intelligent argument processing, e.g. if
+ you can have one callsign, you can have several. Interpret your
+ arguments; so for example:-
+
+ set/qra jo02lq - sets your own locator to JO02LQ
+ set/qra g1tlh jo02lq - sets G1TLH's locator (if you are allowed)
+
+ or
+
+ show/qra in92jo - displays the bearing and distance to
+ IN92JO using your lat/long or locator
+ show/qra jn56in in92jo - bearing and distance between two
+ locators
+
+* It is important that you remember when you have tie hashes using MLDBM
+ et al. If you do a DXUser->get($call) you will get a different (older)
+ thing than the one in $self->$user. This is almost certainly NOT what
+ you want if want to modify a user that is currently connected.
+
+* 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.
