[Haskell-cafe] Tool to brute-force test against hackage libraries to determine lower bounds?

I don't know about you, but I personally haven't found the time to cast back in time for each of my package's dependencies to find a true lower bound version. Do we have any tools that would do the following? - ask Hackage for the available versions of package foo - use cabal-dev to build your package against foo-X.Y.Z forall {X,Y,Z} (but leaving other packages unconstrained) - report successes and failures, including last failure before the present version (and therefore lower bound, exclusive) Johan, would it make any sense to extend your Jenkins setup to do this? -Ryan
