A tool I am using is Ralf Hinze's lhs2tex

  http://www.informatik.uni-bonn.de/~ralf/Literate.tar.gz

  http://www.informatik.uni-bonn.de/~ralf/Guide.ps.gz

It transforms .lhs files (with some formatting commands in LaTeX-style
comments) to LaTeX. Development based on this idea is something I would be
willing to participate in as I already have a fair amount of Haskell
code/articles (read: my PhD thesis;-) in this format.

Maybe Ralf can say something about his views on further development of
lhs2tex (copyright etc.) by other people (us?).

PS. I have made some small improvements to lhs2tex locally and I seem to
    remember that one or two of those were actually needed to get it to
    run with my ghc version.
