C--   1) collect configs from all components

C     Receive ocean config (OCNCONFIG) from ocean component (OCN).
      CALL CPL_RECV_OCN_OCNCONFIG

C     Receive atmos config (ATCONFIG) from atmos.  component (ATM).
      CALL CPL_RECV_ATM_ATMCONFIG

C--   2) send to all components the configs of the other component

C     Send atmos. config (ATMCONFIG) to ocean component (OCN).
      CALL CPL_SEND_OCN_ATMCONFIG

C     Send ocean config (OCNCONFIG) to atmos. component (ATM).
      CALL CPL_SEND_ATM_OCNCONFIG

C--   3) define length of the run (number of coupler time-step)
C        and check for consistent Coupler config (vs components)
