cabal-setup configure
cabal-setup build
cabal-setup install

etc. The command line interface is exactly the same.

cabal-setup is a wrapper program that manages compiling the Setup.hs script if
necessary or if the package is using the 'Simple' build type (and the version of
Cabal required by the package is compatible with the one cabal-setup was built
with) then it calls into the Cabal lib directly.

This is a bit quicker and is useful for simplicity and security. For example the
VisualStudio plugin has never supported running Setup.hs scripts so it has
effectively only ever used the 'Simple' build type. Many people are nervous
about the security implications of running Setup scripts since they can perform
arbitrary IO actions. Calling the Cabal lib directly is a little better.

You can grab cabal-setup now from:
http://darcs.haskell.org/cabal-setup/
and I hope it will also be included in the 'extralibs' tarball that will be
released at the same time as ghc-6.8.1.
