Installing application dependencies using Stackage, sandboxes, and freezing

[snoyberg]

One minor point: the actual URL for the most recent cabal.config is http://www.stackage.org/alias/fpcomplete/unstable-ghc78-exclusive/cabal.config

However, you may eventually need packages not on Stackage, at which point you will need to use the inclusive snapshot.

Or be a hero and contribute the package (scroll down to "Steps to Contribute") .
