package: add enscript

GNU Enscript is a free replacement for Adobe's enscript program.
GNU Enscript converts ASCII files to PostScript, HTML, or RTF and
stores generated output to a file or sends it directly to the
printer. It includes features for `pretty-printing' (language-
sensitive code highlighting) in several programming languages.
