[Haskell-cafe] access programs own documentation

[adam vogt]

Hi Corentin,

One way is to call `ghc-pkg describe Nomyx-0.4.1` and look for the
line starting with haddock-html. Or maybe look at how ghc-pkg does it
<https://github.com/ghc/ghc/blob/master/utils/ghc-pkg/Main.hs>.

This can fail sometimes (though perhaps not for documentation), since
you can have multiple packages with the same name and version
installed, and I don't know how you can get the ABI hash of a
dependency into a program.

Regards,
Adam
