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