+SYNOPSIS
+	void receive_udp(string host, string msg, int hostport)
+
+DESCRIPTION
+	Handle a received IMP message.
+
+	This function is called for every message received on the IMP

+	inter mud communications.
+

+	The 'hostport' argument was added in 3.2.1.
+  LDMud 3.2.9 renamed this method to receive_udp(); this old version
+  is supported if the driver is compiled with USE_DEPRECATED.
+  Removed in LDMud 3.3 and LP "03.02.1@150".
