It is the beginning of a test suite, which is long overdue. Writing a test suite for this code would have saved a lot of work ages ago. But as I always say, if you don’t do it from the beginning, it’s much harder to do later. And this code began its life as a script someone else wrote, so I wasn’t there at the beginning. Better late than never.
