                0035 C note: most of the "experimental" options listed below have not yet

b35e06869b Jean*0040 C     The following five CPP options are experimental and aim to deal
                0041 C     with artifacts due to the low-frequency specification of sea-ice
88f72205aa Jean*0042 C     boundary conditions compared to the model forcing frequency.
b35e06869b Jean*0043 C     Ice convergence at edges can cause model to blow up.  The
                0044 C     following CPP option fixes this problem at the expense of less
                0045 C     accurate boundary conditions.
