		 Triangle Bounder/Smoother for POV-Ray
		    Copyright (c) 1993 Steve Anger

    A number of C routines that can be used to generate POV-Ray ray tracer
 files from triangle data.  Supports generation of smooth triangles and an
 optimal set of bounding shapes for much faster traces. This program may be
 freely modified and distributed.
