aisoshad - a BW halftoning shader using isoparametric curves. Dumps
	   isoparametric curves at a density which is a function of the
	   illumination. Output can be hidden curve removed using zbufcrvs.
mssketch - a kluge to sketch freeform curves using a mouse and convert them
           into Bspline curves in IRIT format.
scripts  - some '.irt' irit script files.
skeleton - a simple IRIT skeleton program
wavefrnt - filters to and from wavefront obj format for polygonal data.
zbufcrvs - Loads curves and surfaces, renders the surfaces into SGI's
	   Z buffer using gl and extracts the visible portion of the curves
	   and dumps it out. To be used with aisoshad.
