[Haskell-cafe] Cabal question, adding data files

Hi, I have a cabal executable, which requires additional data files. How do I do this in Cabal? I have seen extra-source-files, but they are not added at install time to the destination directory, which doesn't help me. I noticed that Alex does this, but with a lot of Cabal calling in Setup.hs with hooks etc, which is not really ideal. Is there any easy way to do the "install these files along with the program, please" ? If anyone needs any concrete examples, take for example HsColour, which needs the files .hscolour and hscolour.css, but currently install doesn't put either of them anywhere useful. Thanks Neil
