Hi devs,

Here's another reminder, now that most people are back from holidays.

For code for the GROMACS 2019 release, to have an impact on users (or
hardware sales ;-)), the design and architecture discussion should be
pretty much over. Code needs to hit Gerrit ASAP, with the usual caveats
about modularity, conformance to the style guide, with unit tests,
developer documentation and user documentation. On Oct 15 we will roll the

I will try to get to get back to several of you this week :-)
