       --ii     Input  data given for (i/o).  Without this flag, all input data,
	      (i) or (i/o), should be given and intermediate output can not be
	      input for run.


       In  example,  [belevation]  map	will  be  created from [elevation] and
       [basin] every run.  However, every [belevation] output map is the  same
       and this is useless process if [belevation] map is already given.


       With this flag, intermediate output can be input for run.  (i/o) param-
       eters can be affected by this flag.

       --oo     Overwrite outputs

       --ww     Wide output.  No limit for 80 columns output

	      (o)   Depressionless elevation map This can be omitted if  [ele-

	      [depressionless]	 map will be used as [elevation] map.
