As far as I can see the docs don't mention it at all, anywhere. Any pointers?
We don't have much. The student who originally did the implementation
wrote this paper:
http://timeguy.com/cradek-files/emc/Leto_art837759.pdf
There is just a bit of gcode documentation in there. The format for
defining a NURBS (G5.2, G5.3) is shown starting at the bottom of page
4.
The format for defining a quadratic b-spline is not in that document
and is G5.1, XY are the endpoint, IJ are incremental distance to
control point.

Thanks! More good reading... ;-)
