Micha, et al.:

   My interest is an area 2.1% of the drainage basin. Reading the r.watershed
manual page I'm not seeing how to specify the project area (a vector
polygon) as the focus of the module while using the raster DEM of the entire
basin to keep all results positive within the defined area.

Guidance appreciated,
