Re: A work-in-progress guide to extending LilyPond

Jean, if there was a Fields Medal for Lilypond, it would be awarded to 
you. Thank you for this. It is so sorely needed. Despite having been a 
professional software developer and architect for forty years. try as I 
would, I have never been able to wrap my head around Lilypond internals, 
and so have felt unable to contribute to development.
