# 1) decoupling makes it viable to use a custom branch of mason that might
# modify the upstream s3 bucket in a such a way that does not give
# it access to build tools like clang++
# 2) Allows us to short-circuit and use a global clang++ install if it
# is available to save space for local builds.
