Use of r.water.outlet

[N R A]

Thanks for the help Chuck. 

It would seem that the 'aspect' map of 'r.watershed' is in the right 
format for 'r.water.outlet' - well the basin it derived certainly looks 
right, especially when compared to our hand drawn ones - in fact the test 
run highlighted some errors in our comparison catchment  8-(

I see what you mean by the only selecting a small 'catchment' - not too 
sure that our digital rivers and DEM have been registered with each other.
