Makefile

# This Makefile attempts to follow the best-practice set out by Alexis King
# in "An opinionated guide to Haskell in 2018" where we build developer tooling
# as part of the project environment rather than globally. This ensures that
# tools like `ghcmod` are using the same version of GHC as our target runtime to
# get the most relevant results.
