>From a previous post I realize r.terraflow isnt working in 6.4 yet.., so
thought I would try a dumbed-down-DEM with r.sim.water ... DEM, mask,
slope, aspect, etc  look good; everything seem to run, but...no outputs
are generated.... hmmm...?
( I can take this to users' list if this is the wrong place, but seems a
lot of things are in motion here...)

thanks in advance!
