The latest is that the project is over and I have a dump of stuff I need
to integrate into LilyPond before it may be useful.  My motivation to do
that is so-so as I've not yet seen a cent of the tutor's money yet (and
no mention whatsoever that there is any intent of or procedure for a
payout) for the considerable work I put in so far, and there does not
seem much of a point to ask for it when the code is not yet in LilyPond.

So it will likely arrive sometime next year.  It's just a starting
point, anyway, but it uses decidedly different techniques than current

Anybody wanting to get that dump and a sketch of how to integrate it is
welcome.  It's Scheme-only work requiring digging through LilyPond's own
Scheme internals for existing hooks in order to integrate it into a
command line utility.
