+			DAYLIGHT FACTOR CALCULATION
+
+This script calculates daylight factors, illuminance levels, and/or
+energy savings due to daylight on a rectangular workplane and produces
+a contour plot from the result.  The input is a Radiance scene description
+(and octree) and the output is one or more color Radiance pictures.
