My swing function at <URL: http://crism.maden.org/music/swing.ly > may
be a starting point.

It currently doesn’t look at the actual on-beat points, but takes pairs
of eighth notes.  It doesn’t deal with dotted quarters or ties... but
it’s a start.

The code is public domain, but if anyone improves it, I’d certainly like
to see what comes out of it.
