Hello, I'm having a bit of fun trying to get Cabal to make Haddock docs for Takusen. Takusen's sources are a mixture of .lhs (birdtrack), .hs, and .hsc files. .hsc files are preprocessed OK, but the cabal source code for the haddock build action, and also the preprocessor code, seems to deal with .lhs -> .hs as a special case. The normal .lhs -> .hs preprocessor strips comments, which is useless for hadock. I have tried to hook in a custom preprocessor to turn .lhs into .hs (while preserving comments), but this is not triggered because of the hard-coded special cases for .lhs -> .hs. I have resorted to lifting out the entire hadbock function from Distribution.Simple, and modifying it so that it does nothing special for .lhs files. My own .lhs -> .hs transformation runs just before the new haddock hook. Does anyone have a better solution than this? Also, when I finally run haddock, I get this (sorry about the odd formatting, it's a cut-'n'patse from a Windows cmd.exe terminal): C:\haskell\bin\haddock.exe --html --odir=dist\doc\html --title=Takusen-0.7: Data base access library with left-fold interface.

I've copied them up to c:\ghc\ghc-6.6.1\html\libraries to try to keep haddock happy, but as you can see... 2. even with the base.haddock etc files in the right places, haddock still doesn't find them. !?
