 * 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)
