Comment (by snowleopard):

 > Is the basic idea to just make it so that more things (e.g., the number
 of threads and the output directory) can be customized within `Flavour`?
 And, once that's in place, to allow overriding which build flavour is the
 default? If so, that sounds swell to me.

 Yes, that's the plan.

 > There's one more thing [...]

 Sure, adding `--progress-colour` to `Flavour` shouldn't be difficult, I'll
 do that too.
