What documentation did you have to help you? Or did you just copy an existing
command as a template and change it to one that built wheels?

That certainly sounds saner than the distutils dance.

Is that documented? Is it the "build manifest" mentioned in the "Design notes"
part of the documentation?

Well, yaku seems something of a black box, and I'm not sure how that's a good
thing.

Well, the Bento documentation itself refers to its "weak documentation" and
"mediocre code quality" - while I don't think David needs to be quite so
self-deprecatory, I would definitely agree about the documentation :-)

I'm not currently planning to use Bento - my interest at present is just to see
if it might conceivably be a potential client of distlib.
