[Haskell] cabal feature request

I finally succeeded using cabal for a project that uses hsc2hs. My problem was/is I need to give special options to hsc2hs, for instance a different template header file to use. Cabal doesn't support this at the moment. I propose to give the user a bit more flexibility with regard to preprocessors, i.e. add some more tags to the .cabal file, like hsc2hs-options, cpp-options, ... I made the necessary changes for hsc2hs-options in a few minutes (thanks to the nicely structured cabal libraries :). Another question: Is there a proposal how to (better) support test executables for a library package? (I remember that this topic has been discussed but can't remember any conclusion). Cheers Ben
