[Haskell-cafe] Cabal sandboxes over cabal-dev (Rogan Creswick)

[Curtis Gagliardi]

As a noob to haskell, is there a tutorial or anything someone can point me
to that's up to do date about how to use cabal with sandboxes?  Now that
I'm trying to do more than play around at the repl, I'm trying to get up to
speed with cabal and the ecosystem, but all the tutorials I see either
recommend cabal-dev or don't mention sandboxing at all.
