local-test

#!/usr/bin/env bash
#
#   pactivate local-test - Run basic test on local machine
#
#   This runs a very basic test on the host system, with whatever
#   configuration it happens to have, as opposed to the full set of tests
#   in specific configurations run in a Docker container. It can be used
#   to confirm operation on your own configuration of Linux and also test
#   Mac and Windows, which cannot (currently) be tested with Docker.
#
#   XXX Much of this code is common with cont-test; perhaps we should
#   extract some of the common elements.
