Attempted overnight sleep failed :(  Sleeping late afternoon and early

Having raised the issue I certainly understand things much better, 
especially because of the words from Ned Deilly.

So a question springs to my mind.

How do we educate the people putting their code on pypi to correctly set 
up the relevant fields so that it can be correctly handled by any tools 
that want to download from pypi?

How does the lack of correct data and/or code on pypi add more credence 
to the impression that libraries are not ready for Python 3 when in 
actual fact they are?
