Would it be possible to give a brief explanation for what this is all
about?  When reviewing something I usually start by reading the
description and then check the code matches what was written, but your
text doesn't really help me ... I suspect there's some back story that
I'm missing, but it would be neat if that could all be summarised, or at
least links to it added, here.

Thanks,
Andrew
