+15Feb99========================================================================
+1. Added msg forwarding code which uses $main::root/msg/forward.pl.
+14Feb99========================================================================
+1. Changed A & K in WWV to be the other way around (I am told by G3IOR that
+this will mean that we won't have pole to pole aurora nor all the power lines
+overloading everywhere as well as a result of having values of K > 10).
+2. allow the '~' character in message bodies.
+3. Moved $main::data/badmsg.pl to $main::root/msg/badmsg.pl.
 11Feb99========================================================================
 1. Fixed a problem with isolated nodes' configurations being sent on sending 
 local configs to new connections.

+# this is an example message forwarding file for the system
+#
+# The format of each line is as follows
+#
+#     type    to/from/at pattern action  destinations
+#     P/B/F     T/F/A     regex   I/F    [ call [, call ...] ]
+#
+# type: P - private, B - bulletin (msg), F - file (ak1a bull)
+# to/from/at: T - to field, F - from field, A - home bbs, O - origin 
+# pattern: a perl regex on the field requested
+# action: I - ignore, F - forward
+# destinations: a reference to an array containing node callsigns
+#
+# if it is non-private and isn't in here then it won't get forwarded 
+#
+# Currently only type B msgs are affected by this code.
+# 
+# The list is read from the top down, the first pattern that matches
+# causes the action to be taken.
+#
+# The pattern can be undef or 0 in which case it will always be selected
+# for the action specified
+#
+# If the BBS list is undef or 0 and the action is 'F' (and it matches the
+# pattern) then it will always be forwarded to every node that doesn't have 
+# it (I strongly recommend you don't use this unless you REALLY mean it, if
+# you allow a new link with this on EVERY bull will be forwarded immediately
+# on first connection)
