The lit2x-0.19* files are the Glasgow Literate Programming tools, extracted from the Glasgow Haskell 0.19 distribution. Version 0.19 has a few bug fixes since 0.16 (and earlier versions), plus some "lit2html" code contributed by Chris Toshok . Way cool stuff! (HTML is the Hypertext Markup Language, used on the World-Wide Web.) He also contributed some Standard ML (SML) support code. I'll make 0.16-0.19 diffs if someone asks for them.
