script:
  # Travis will time out our build if doesn't output anything for > 10 mintes,
  # but --verbose sometimes outputs more than 4 MB of data, which will also
  # cause our build to be killed. travis_wait allows the command to be silent
  # for longer, but has the downside of not producing output if we timeout. See:
  # https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received
  # For now, stick with --verbose and keep an eye on the logs.
