PostScript

I remember back when a "mouse" had four legs, "PostScript" was what came at the end of a letter, and "Unix" was a term for someone who'd had his works cut out for him.

README:
"Ghostscript is a PostScript interpreter.  PostScript is a language, not a graphic file format.  A PostScript file is really a program, not graphical data.  The difference is that by looking at a PostScript file you (or an application) cannot easily tell what the file represents. Instead, you must run the file to see what it does. 
Think of Mac GS Viewer as a virtual printer:  Every time you open a file, asking Ghostscript to run it as a PostScript program, the application creates a new sheet of 'paper' and displays it in a window."
