 # DX cluster message strings for output
 #
+# Each message string will substitute $_[x] positionally. What this means is
+# that if you don't like the order in which fields in each message is output then 
+# you can change it. Also you can include various globally accessible variables
+# in the string if you want. 
+#
+# Largely because I don't particularly want to have to change all these messages
+# in every upgrade I shall attempt to add new field to the END of the list :-)
