These are unsupported versions of the test scripts for CW1-CW4. If you want to try to run them locally, you'll need to try to deal with any errors that occur (e.g. file permissions problems, missing tools, etc.). They aren't designed to be difficult to run, but neither are they necessarily easy to run (though maybe they are).
They are designed to run only in an environment that I control, which is nominally the AWS HPCE AMI or an equivalent vagrant install, but may include other tools that have been manually added that I didn't think about. They are also likely to drift out of sync with the master scripts, as they won't contain any point fixes.
