   Parameters:
       cnetwork=nameA [required]

DESCRIPTION
       r.basins.fill generates a raster	map layer depicting  subbasins,	 based
       on  input  raster  map  layers for the coded stream network (where each
       channel segment has been	"coded"	with a unique category value) and  for
       the  ridges  within  a given watershed.	The raster map layer depicting
       ridges should include the ridge which defines the perimeter of the  wa-
       tershed.	  The  coded  stream  network  can be generated	as part	of the
       r.watershed program, but	the map	layer of ridges	will need to  be  cre-
       ated by hand (for example, through digitizing done in wxGUI vector dig-
       itizer).

       The resulting output raster map layer will code the subbasins with cat-
       egory  values  matching	those  of the channel segments passing through
       them.  A	user-supplied number of	passes through the data	is made	in  an
       attempt	to  fill  in these subbasins.  If the resulting	map layer from
       this program appears to have  holes  within  a  subbasin,  the  program
       should be rerun with a higher number of passes.

NOTES
       The  current  geographic	 region	setting	is ignored.  Instead, the geo-
       graphic region for the entire input stream's map	layer is used.

       See Appendix A of the GRASS Tutorial: r.watershed for  further  details
       on the combined use of r.basins.fill and	r.watershed.
