# ATTENTION! Before editing this file, maybe you can make a
# separate script to do your test?  We don't want individual
# Travis builds to take too long (they time out at 50min and
# it's generally unpleasant if the build takes that long.)
# If you make a separate matrix entry in .travis.yml it can
# be run in parallel.

# NB: the '|| exit $?' workaround is required on old broken versions of bash
# that ship with OS X. See https://github.com/haskell/cabal/pull/3624 and
# http://stackoverflow.com/questions/14970663/why-doesnt-bash-flag-e-exit-when-a-subshell-fails
