Hello cafe, Let me announce "cab version 0.1.2". This version integrates "cabal-dev" as well as "cabal/ghc-pkg". So, you can use a sandbox for your development. http://www.mew.org/~kazu/proj/cab/en/ Here is the short explanation from the page above: ---- "cab" is a MacPorts-like maintenance command of Haskell cabal packages. Some parts of this program are a wrapper to "ghc-pkg", "cabal", and "cabal-dev". If you are always confused due to inconsistency of "ghc-pkg" and "cabal", or if you want a way to check all outdated packages, or if you want a way to remove outdated packages recursively, this command helps you. "cab" is designed to maintain user packages only assuming that users use a Haskell Platform and don't want to touch the global packages. ---- --Kazu
