# The different configurations we want to test. We have BUILD=cabal which uses
# cabal-install, and BUILD=stack which uses Stack. More documentation on each
# of those below.

# We set the compiler values here to tell Travis to use a different
# cache file per set of arguments.

# If you need to have different apt packages for each combination in the
