[Distutils] DU2 1.0a5

[Éric Araujo]

Hi Rob,

I really can’t predict.  I could release a5 right now, but it only has a
couple fixes compared to a4; I would like to have some more significant
fixes, like the bytes/string I/O errors in the register command, or the
many bugs that show only on Windows fixed, or new features like the
develop command.

The next sprint is to be confirmed on the 9th.

Cheers
