# It may seem surprising that we don't dogfood stack itself here. The reason is
# twofold:
# 1. We want to ensure that the bootstrapping case works
# 2. Building with stack would be too easy a test, since it guarantees us a
# sane build environment. In CI, we want to make our life more difficult, so we
# use cabal without any Stackage snapshots.
