The program could certainly be generalized more, and certain features (such as wrapping
long lines) could be handled. I could also wade into the debate among PostScript experts as
to how much of the formatting should be done on the main computer and how much should
be done by the PostScript program interpreter running in the printer. But perhaps I won't get
into that discussion. At least, not today.
