I am trying to extract a simple static information out of the cabal file: the hs-source-dirs

Is there a way to get this without resolving conditionals, or with minimal effort? (I don't even understand how to resolving conditionals.)

If you write in a package description: If flag(foo) Hs-Source-Dirs: foo Else Hs-Source-Dirs: bar then Hs-Source-Dirs depends on conditionals. I use this technique in order to select specific modules for Unix and Windows without CPP. How do you want to extract Hs-Source-Dirs without knowing the flag values?
