Pier is a command-line tool for building Haskell projects. It is
similar in purpose to Stack,
but explores a different design:
Pier implements the fine-grained Haskell build logic from (nearly)
scratch. In contrast, Stack relies on Cabal to implement most of its
build steps, giving it a more coarse control over the build.
Pier uses general-purpose libraries for implementing build systems, namely
Shake and pier-core.
