Hi Markus,

We plan to do a Phenix release in December, so I would just upgrade scons first and then work on making the build system work for both Python 2 and 3. The steps for using scons 3.0.0 would be,

1) Use Python 2 to build Python 2 version of CCTBX (no work)
2) Use Python 3 to build Python 2 version of CCTBX (some work, some disentangling requried)
3) Use Python 3 to build Python 3 version of CCTBX (more work and will probably take a while)

This would be done on macOS 10.9-10.12 (and probably 10.13), CentOS 5-7, and probably Ubuntu 14.04 -16.04. I'll need Rob's help with Windows.

That's 3 weeks from now. If we do a 3 week freeze for every DIALS release, plus for phenix releases etc, cctbx would be trapped in perma-frost :)
Feel free to start on it now - if it causes issues I can always pick a stable point in the past to branch off from.

Great! There's a DIALS release on October 31, so I can start making changes after that.

Perhaps start using this to easy upgrading cctbx to python 3
