PIC is a troff preprocessor for drawing pictures.  It supports
Autologoic APS-5, Xerox 9700, and Imagen Imprint-10 printers.  I
believe it is a standard part of AT&T UNIX, but not Berkeley UNIX.
AT&T also sells a graphics terminal (the 5620 DMD) that, among other
things, (with supporting software called CIP) allows you to draw
pictures with a mouse and save the pictures in PIC format for later
processing by troff.

More info on PIC may be found in "Pic: A Language for Typesetting
Graphics", by Brian Kernighan, *Software - Practice & Experience*,
volume 12, January, 1982, p. 1-20.
