 # This is a perl module/program that sits on the end of a dxcluster

+# this program is called by ax25d or inetd and gets raw ax25 text on its input
+# It can also be launched into the ether by the cluster program itself for outgoing
+# connections
+#
+# Calling syntax is:-
+#
+# client.pl [callsign] [telnet|ax25|local] [[connect] [program name and args ...]]
+#
+# if the callsign isn't given then the sysop callsign in DXVars.pm is assumed
+#
+# if there is no connection type then 'local' is assumed
+#
+# if there is a 'connect' keyword then it will try to launch the following program
+# and any arguments and connect the stdin & stdout of both the program and the 
+# client together.
