Nice! I've just tested things under Windows, and everything works for me so far, only one tiny nit remains: In the documentation index (file:///.../Haskell%20Platform/7.10.2/lib/extralibs/doc/index.html) package names for the non-GHC packages are still missing in the right column, see http://i.imgur.com/jh0u8EP.png. I'm not sure if this is a glitch in the HP build or a bug in Cabal or a bug in Haddock or..., so I don't know where to open an issue. Does anybody have a clue what might cause this? If I build packages locally in a sandbox, their documentation shows similar bugs. Is this working for other people or do they experience the same behavior?
