 <EM>r.plane</EM> creates a tilted plane raster map given user-specified
 parameters for inclination, azimuth, and the geographic location of a
 point on the plane.<BR>
-The angle orientations of <em>azimuth</em> are: 0 degree = N, 90 degree = E etc.
+The angle orientations of the <em>azimuth</em> parameter increase counter-clockwise,
+i.e., 0 degree = N, 45 degree = NW, 90 degree = W etc.
+<P>
+Increasing values of the <em>dip</em> parameter progressively lower (or dip) the northern
+half of the plane, and incline the southern half, assuming the <em>azimuth</em> parameter 
+is held constant at 0 degrees.
