The layout is pretty simple.  The index file

	http://hackage.haskell.org/packages/archive/00-index.tar.gz

contains all the .cabal files.  From their names you can figure out the
locations of the source bundles, e.g.

	AGI/1.1/AGI.cabal
	->
	http://hackage.haskell.org/packages/archive/AGI/1.1/AGI-1.1.tar.gz

You can easily slurp the lot.

The HackageDB wiki page has more details:
