Hi James,
See: https://lilypond.org/doc/v2.21/Documentation/contributor-big-page.html#building-a-single-documentDid you do the 'touch' command?
Now I did :-) (thanks!), but touch'ing notation.tely doesn't do the trick.If I'm not wrong, my question is how to force a re-build of out-www/en/identifiers.tely.
