The PostScript interpreter is easy.  The graphics libraries are the
hard part.  James Gosling, who wrote the PostScript interpreter in the
NeWS window system, told me that he spent a week on the interpreter
and over a year on the graphics libraries.  That's not counting the
font scaling.  Sun bought a company just to get the font scaling
technology (Folio).

By the way, using the  [:  ...  ;]  construct that Dr. Wavrik described
in a recent posting, you can easily implement PostScript-style control
structures (as Tom Almy alluded to).
