NAME

       dayfact - compute illuminance and daylight factor on workplane

SYNOPSIS

       dayfact [ falsecolor options ]

DESCRIPTION

       Dayfact  is an interactive script for computing workplane illuminance, and daylight factors and potential
       daylight savings using rtrace(1).  The script falsecolor(1) is then used to draw  contour  lines  on  the
