Side note: in my early days on Windows years ago I spent a good couple
of hours trying to figure out why some tests were failing, to discover
I had installed the wrong tool.
I don't recall whether the documentation points to the one true
version of sed/awk/* required, but in case it doesn't, maybe we might
consider adding it?
