 * Copyright (c) 1985 Adobe Systems Incorporated
 *
 * inspired by Gosling's cz
 * there have been major overhauls, but the input language is the same:
 * 	new widths format
 *	generate PostScript (much easier than Press)
 *	new and renamed switches (to match 4.2bsd lpr spooler)
 *	obeys PostScript comment conventions
 *	doesn't worry so much about fonts (everything is scalable and
 *	rotatable, use PS font names, no face properties)
 *
 * enscript generates POSTSCRIPT print files of a special kind
 * the coordinate system is in 20ths of a point. (1440 per inch)
