  * Switch from DepGraph to InstallPlan
  The dependency resolver has had to be extended in a slightly hacky
  way to gather the extra information needed by an install plan. In
  particular it requires the flags to use to configure each package,
  the actual versions of dependencies to use and all of the
  installed packages and their closure of dependencies.
  However the current resolver is fairly naive and so can be easily
  persuaded into producing an invalid install plan, in which case
  you'll get a detailed list of reasons as to why it is invalid.

    R ./Hackage/DepGraph.hs
    M ./Hackage/Dependency.hs -28 +84
    M ./Hackage/Fetch.hs -4 +7
    M ./Hackage/Install.hs -43 +35
    M ./cabal-install.cabal -1
