PROGRAM ce0l
!
!-------------------------------------------------------------------------------
! Purpose: Calls etat0, creates initial states and limit_netcdf
!
!     interbar=.T. for barycentric interpolation inter_barxy
!     extrap  =.T. for data extrapolation, like for the SSTs when file does not
!                  contain ocean points only.
!     oldice  =.T. for old-style ice, obtained using grille_m (grid_atob).
!     masque is created in etat0, passed to limit to ensure consistancy.
