Parameters:
- cnetwork=name [required]
- Name of input coded stream network raster map

- output=name [required]
- Name for output raster map
- number=integer [required]
- Number of passes through the dataset
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 watershed.
The coded stream network can be generated
as part of the
r.watershed program,
but the map layer of ridges will need to be created by hand
(for example, through digitizing done in
wxGUI vector digitizer).
The resulting output raster map layer will
code the subbasins with category 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.
The current geographic region setting is ignored.
Instead, the geographic region for the entire input stream's
map layer is used.
