  directories:
  - $HOME/.ghc

  - $HOME/.stack

# 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
# matrix, you can use a line such as:
