Yes, I've seen that, and as you say this only gives information about 
C++ engravers.

But I do have an engraver written in Scheme (not by me) that I find very 
useful. I could make it available in openlilylib, but I think it's a 
very common notation that should be available in LilyPond itself 
(printing double barlines before time signature changes).

Do you want to say that it's inappropriate to add Scheme engravers to 
LilyPond and that it should be rewritten in C++ for that (which I couldn't?
