I have read a few messages about this mysterious editionEngraver and I would like to try using it, but I am doing something wrong and I don't know what. I found the folder for it on github and tried to use it by downloading the three files there (definitions.ily,
example.ly, and module.scm) into the same folder and trying to compile
example.ly, but it throws back the error: cannot find file: `scheme-lib/modules.ily' (and some others which presumably stem from this one).
Separately the instructions on the page say I need to add the line \include "edition-engraver.ily" from this folder, but I can't seem to find the file. I've never used github before so perhaps I have misunderstood what I am supposed to do. Any help would be welcome.
