-- | The general Stack configuration that starts everything off. This should be
-- smart to fallback if there is no stack.yaml, instead relying on whatever
-- files are available.
--
-- If there is no stack.yaml, and there is a cabal.config, we read in those
-- constraints, and if there's a cabal.sandbox.config, we read any constraints
-- from there and also find the package database from there, etc. And if there's
-- nothing, we should probably default to behaving like cabal, possibly with
-- spitting out a warning that "you should run `stk init` to make things
-- better".
