There is a simple test harness which can be invoked via `make test`. If you wish
to port this software to an untested platform the tests will greatly assist in
that process.
> Note: if your OS uses **dash** as `/bin/sh` then the builtin echo command will not
> be up to the task of printing the escape sequences used by the test runner. If this
> bothers you, you can call `make` with the `SHELL` environment variable overridden
> by calling `make SHELL=/bin/bash all test`.
