[Haskell-cafe] Literate programming

Hello all, Is literate programming something you guys actually do (I only know that Paul Hudak does), or is it basically a nice idea from days gone by? In case you do, then how do you do it? Do you use lhs2TeX or what? Do you use "bird" style of full-blown LaTeX? Does any of you use leksah? I failed to see any support for literate programming in leksah. It candies the backslashes in e.g. \documentclass{article} to λdocumentclass{article}. In case you don't, then how do you document your code? If you write a paper which explains what your code does, then how do you do that? -- Martin
