Nenscript is a clone of the proprietary enscript program from Adobe Systems. For those who have never used enscript, it is a pretty printer and paginator that accepts raw text and outputs PostScript complete with headers, footers, and other useful ornaments.
nenscript was written by me over a period of several months in 1992 whilst I was working at Computer Sciences of Australia as a contractor. The development team I was with was making heavy use of enscript, but that product did not make the jump from the old Sun 3 to new Sun 4 boxes that were being phased in.
After writing it, I saw that several people had a similar problem. So I convinced my manager that this would be a Good Thing to release this as open source.
