Comment:
Well, this at least guarantees we can import the whole thing, I guess.

If they ever add tests, we'll be ready to run them :D 

Maybe add a comment that currently no tests are defined? I definitely think `do_check` should remain like this. Possiby change `python` to explicit `python3` there too,
