bin-package-db

Hello, The release note of GHC 7.0.2 says: ---- 1.5.6.3. bin-package-db This is an internal package, and should not be used. ---- What is the intention of this change? The author of "cabal-delete" hesitates to register "cabal-delete" into HackageDB due to this words. Shouldn't a package-maintenance command even use this package? If so, what package should be used? --Kazu
