I have some source files which need CPP style preprocessing. Since I am using GHC, I would like to automatically use GHC's preprocessor instead of having to download and install cpphs. For example, I want to "runghc ./Setup.hs haddock" without cpphs installed. However, references to cpphs are hard-coded into Cabal. What is the best way to go about accomplishing this?

 

Thanks,

Brian
