I'm wanting to get started writing an engraver in Scheme. Searching lists I don't find a lot of information for starting out on this sort of work. Does anybody have any pointers to how to get started creating an engraver in Scheme? Tutorials, examples, explanations?
I understand the example on the lilypond blog for adding ornaments to note heads is somewhat out of date, and I would rather start off with something more current if possible.
