	Depends on the CCIDs available on the server; this information
	can be seen in the display of 'para_client si'.

	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).

	The request is reconciled with the CCIDs on the server via
	the 'server-priority' mechanism of RFC 4340 6.3.1/10.
