+	Depends on the CCIDs available on the server; this information

+
+	When present exactly once, this option mandates the CCID
+	to use for the sender-receiver connection.
+
+	If it is passed more than once, it sets a preference list
+	of CCIDs for this connection. The order of appearance here
+	signifies descending priority. For example,
+		    --ccid 4   --c 2   --ccid 3
+	generates the preference list (CCID-4, CCID-2, CCID-3).
+
