Do you know of any way to use multiple stackage repositories? (for now it's not a problem, but I envision a future when I'll have dozens of projects, and updating everyone of them to use the same library versions might not be feasible)
I know that I can `cabal --config-file=/path/to/cabal.config` but I'm wondering if there's an easier way and/or any convention
I'm especially worried of forgetting something (like reusing the same ~/.cabal for multiple stackage-cabal configs)
