207    Another way users can force the splitting of MNC files along the time
208    dimension is the \texttt{mnc\_filefreq} option.  With it, files that
209    contain variables with a temporal dimension can be split at regular
210    intervals based solely upon the model time (specified in seconds).
211    For some problems, this can be much more convenient than splitting
212    based upon file size.
