That's interesting. I was recently thinking of generating something like CabalInfo.hs which has information like the PackageDescription and the LocalBuildInfo. You would turn on this feature w/ the .cabal file. I'm not sure if any of the information is useful except for the version number, though.

This isn't necessary: you can get the version number from Paths_<pkg> (it's an undocumented feature :-). See the Cabalised Happy for an example. I should probably document it. Cheers, Simon
