Usage: CTCP <nick> <command> [<args>]
  CTCP allows you access to the client-to-client protocol used
  to perform certain client specific actions between different
  clients on the network.  The CTCP mechanism works by sending
  a specially coded message to another user whose client is
  supposed to reply with a reply message of the type, or with
  an error message, unless you sent it to a channel.

  For example, if you do:
    CTCP BigCheese VERSION
  you will receive:
    *** CTCP REPLY VERSION from BigCheese: ircII 2.2.2 *IX.

  The <command> field may be of several types, new ones are
  introduced all the time, but there is a mechanism for you to
  find out what you can use: see CLIENTINFO.
  If the nickname is "*" the output is sent to the current channel.
