lhs2TeX is a preprocessor to generate LaTeX code from literate Haskell sources.

lhs2TeX includes the following features:

\* Different styles to process your source file: for instance, "tt"
  style uses a monospaced font for the code while still allowing you to
  highlight keywords etc, whereas "poly" style uses proportional fonts
  for identifiers, handles indentation nicely, is able to replace binary
  operators by mathematical symbols and take care of complex horizontal
  alignments.
\* Formatting directives, which let you customize the way certain
  tokens in the source code should appear in the processed output.
\* A liberal parser that can handle most of the language
  extensions; you don't have to restrict yourself to Haskell 98.
\* Preprocessor-style conditionals that allow you to generate
  different versions of a document from a single source file (for
  instance, a paper and a presentation).
\* Active documents: you can use Haskell to generate parts of the
  document (useful for papers on Haskell).
\* A manual explaining all the important aspects of lhs2TeX.
