4  ! Purpose: Initial states and boundary conditions files creation:
5  !     * start.nc    for dynamics    (using etat0dyn     routine)
6  !     * startphy.nc for physics     (using etat0phys    routine)
7  !     * limit.nc    for forced runs (using limit_netcdf routine)
8  !-------------------------------------------------------------------------------
9  ! Notes:
10  !     * extrap=.T. (default) for data extrapolation, like for the SSTs when file
11  !                   does contain ocean points only.
12  !     * "masque" can be:
13  !       - read from file "o2a.nc"          (for coupled runs).
14  !       - read from file "startphy0.nc"    (from a previous run).
15  !       - created in etat0phys or etat0dyn (for forced  runs).
16  !     It is then passed to limit_netcdf to ensure consistancy.
