Re: Building Jython3

Thanks for kicking this specific discussion off. Some points:

1. We can switch to github now if we focus on Jython 3. I would suggest
using squash merges (https://github.com/blog/2141-squash-your-commits).
Then over time we can adopt CPython core workflow.

2. We should bring in the Gradle build process that Darjus is working on,
and get that into Jython 3 as soon as possible.

3. Once we finish pushing the 2.7 changes into Jython 3, hopefully
automated as Stefan suggests, we should backport going forward into 2.7
(some changes will have to be made against 2.7 of course). Having
everything in https://github.com/jython/jython, with a branch for 2.7,
should simplify; and follows the CPython model. This means Jython 3 will
take advantage of the planned history rewriting.
