OK, I'll send a note / question to the Boost list to see who else is
using the `python-tag` rule.

Hmm, more and more distributions rename 'python' to 'python2' to prepare
for a pending move to Python 3 by default. So I'd like to propose we
follow that trend.

I'm not sure I understand,  but I'll look at the code to figure out what
that "versioned-1.66" scheme is.
