To be more clear, it uses the database built by hs-gen-iface ,
which is a compile-like tool that generates an interface database for
your packages. You have to make a separate `cabal` call to use it and
build the database for each package you compile. Hopefully in the
future, cabal will have a way to automatically call compiler-like
tools (think haddock as wel). But for now, it's a bit impractical.

Right now halberd uses the global and user database. It should be
fairly trivial to add support for cabal sandboxes, although there will
probably be some duplication with cabal in the sandbox flags at least.
Let me know if you're interested.
