<h2>DESCRIPTION</h2>
-<p><em>i.his.rgb</em> is an image processing program that processes three input
-images as hue, intensity and saturation components and produces three output
-images representing the red, green and blue colors.</p>

+<p>Hue values are expected to be degrees ranging in [0, 360] while intensity and
