r.slope.aspect

[Elizabeth Weeks Boyer]

Hi.  I am seeking some information about the slope layer generated via r.slope.aspect;
Two questions:

1)  With respect to a pixel's 8 neighbors (3x3 neighborhood), is the slope calculated the 
MAXIMUM slope (this is what I suspect is being calculated) or the AVERAGE slope?
2)  Is there a way to get both the average and steepest slope map layers?

Thank You,
