    of things.

    CRC.TAR-Z
	The CRC Graphics Package from Purdue University.  This package
	contains a general-purpose graphics facility for two and three
	dimensional graphics.  Output devices include HP plotters,
	Printronix printers, laser printers, plot(5) format, and so on.

    DELTAC.TAR-Z
	Compress and uncompress 8-bit image files using delta modulation.
	Achieves about 20% better compression than compress(1) on these
	files.

    DRAW.TAR-Z
	A library of routines to produce plots in various formats including
	plot(3) and HPGL, and a utility "draw" which acts as a front end.
	Contributor: Juha Takala <jta@sah.vtt.fi>
    FBM.TAR-Z
	The Fuzzy Pixmap Manipulation (FBM) library.  Works in combination
	with Jef Poskanzer's PBM stuff (see PBM.TAR-Z).  Provides a complete
	package for manipulation color and b/w images including 24-bit RGB,
	8-bit mapped color, 8-bit grayscale, and 1-bit bitmaps.
	Contirbutor: Michael Mauldin <Michael.Mauldin@nl.cs.cmu.edu>
    FC.TAR-Z
	The Fast Clipper 2-D line clipping algorithm.  Twice as fast as
	the Colin-Sutherland method.
	Contributor: John Schultz <jcs@crash.cts.com>
    GL-PLOT.TAR-Z
	Routines which provide graphic device support for a number of
	video adapters and printers for PC/AT class computers running
	under Microport System V/AT, Xenix or MS-DOS.  The routines
	emulate the BSD plot(3) library, as well as provide new
	routines.  It runs under MSDOS/ System V/AT, SCO

    GRAPH-PLUS.TAR-Z
	A program to generate line graphs from tables of data.
	Contributor: Alan Kent <ajk@goanna.oz.au>
    IPL.TAR-Z
	A 2-D graphics production system which produces scatter plots, line
	plots, bar graphs, range displays, pie graphs, U.S./Canada maps,
	schedule charts, boxes, arrows, text, etc.  PostScript or SunView
	output.
	Contributor: Steve Grubb <scg@lsr-vax.uucp>

	The MTV Raytracer, which does raytracing.
	Contributor: Mark VandeWettering <markv@drizzle.cs.uoregon.edu>
    PBM.TAR-Z
	Tools for manipulating bitmaps.  Can convert between Sun icon,
	Sun raster, X10, X11, MacPaint formats.  Can also convert to
	PostScript or Printronix printer for output.

	produces a Utah Raster RLE format file of the raytraced image.
	Version 3.0.
	Contributor: Craig Kolb <craig@weedeater.math.yale.edu>
    SUN-CTOBW.TAR-Z
