simplifyVersionRange :: VersionRange -> VersionRange

There seems to be a bug in Cabal where serializing and deserializing version ranges winds up with different representations. So we have a super-simplifier to deal with that.

topologicalSort

Arguments

:: (Ord key, Show key, MonadThrow m, Typeable key)

=> (value -> finalValue)

-> (value -> Set key)

deps

-> Map key value

-> m (Vector (key, finalValue))

Topologically sort so that items with dependencies occur after those dependencies.
