NNAAMMEE
       rr..rruunnooffff  (GRASS  raster  command) Generates an SCS curve number runoff
       map layer. It is a command-line interface for generating the runoff map
       by the SCS method.

       rroo==_m_a_p output runoff map name  in *100 mm

       The command-line ordering can be in any	form  but  all	key words must
       be there to run the program.

NNOOTTEE
       The _r_._r_u_n_o_f_f program is sensitive to the current window setting.   Thus
       the program can be used to generate a runoff map of any sub-area within
       the full map layer. Also, _r_._r_u_n_o_f_f is sensitive to any mask in  effect.
