It rather defeats the purpose of os.sep if you include it in a part of
the path. What you mean is better expressed as
join(base, '..', '..', 'build', '')
(and base includes it too, but I can't suggest an alternative because I
don't know your intent is far as defaults go.)

I think it is. The picture is messy on Windows (because of the drive
letter) but absolute paths are usually taken to be those that start with
a path separator.
