A maintenance command of Haskell cabal packages

This is a MacPorts-like maintenance command of Haskell cabal packages. Some part of this program is a wrapper to "ghc-pkg" and "cabal". If you are always confused due to inconsistency of two commands, or if you want a way to check all outdated packages, or if you want a way to remove outdated packages recursively, this command helps you.
