                0048 C     The following five CPP options are experimental and aim to deal
                0049 C     with artifacts due to the low-frequency specification of sea-ice
                0050 C     boundary conditions compared to the model forcing frequency.
                0051 C     Ice convergence at edges can cause model to blow up.  The
                0052 C     following CPP option fixes this problem at the expense of less
                0053 C     accurate boundary conditions.
