[Haskell-cafe] Using cabal-install

[Daniel Fischer]

Is there a tutorial/user's guide for cabal-install somewhere?
My limited google skills haven't found one and I really need it, because there 
MUST be a better way to get a package and its dependencies built and the 
haddock documentation generated, installed and hyperlinked than manually 
unpacking each .tar.gz and running cabal haddock there.

Thanks,
Daniel
