and note the issue about custom vs simple build-type for Cabal itself.

Addresses #191 (QA) and #180 (QA for missing license).
This patch only adds a new exposed module, it's not yet used anywhere.

Since we've changed the exports of the Setup module significantly.
However since this is a dev series I don't think it makes sense to
bump the major version number as in the PVP, or we'd end up doing
it all the time in a development series.

the user's guide separately from the Haddock documentation. 

These are no longer in the tree, they have their own repos now.

This was generating a useless Main entry in the lib doc index.
(good for STABLE)

Without this patch, Cabal is effectively "version-less" and all .cabal
files with a version requirement are unusable. Therefore I think that
this patch (or at least something equivalent) should be pushed to the
6.6.1 branch, too.

This is more normal.

It just makes us look bad! :-)

This is the portable thing to do and fixes things on FreeBSD where make/=gmake

Patch to fix "-ixyz" being overwritten by "-i" and to remove Cabal's dependency on the Cabal package.
