       --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  [eleva-
       tion]  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) parameters can be affected by this flag.
