ircII help: set no_ctcp_flood

Usage: SET NO_CTCP_FLOOD [ON|OFF|TOGGLE]
  When ON, your client will only send out one CTCP reply every 2 seconds,
  and ignore any other CTCP requests it gets in the meantime.
  When OFF, it will process CTCP replies properly, ie
    ^AFINGER blah^A^AVERSION^A
  will work.
