5		* Radiance animation control program
6	+	*
7	+	* The main difference between this program and ranimove is that
8	+	* we have many optimizations here for camera motion in static
9	+	* environments, calling rpict and pinterp on multiple processors,
10	+	* where ranimove puts its emphasis on object motion, and does
11	+	* not use any external programs for image generation.
12	+	*
13	+	* See the ranimate(1) man page for further details.
