  * Refactor sdist code a bit
  Separate the phases of sdist better so that they can be reused in
  cabal-install. This part is similar to Andrea Vezzosi's patch.
  Separate the snapshot code rather than mixing it all in with prepareTree.
  Use a proper withTempDirectory which fixes one FIXME.
  Better separate UI code from actions, move the notices to sdist.
