haawda [1] filed a deletion request for lilypond-devel-docs [2]: Lilypond's stable is in version 2.20 now. So it's docs should be provided by the lilypond-docs package. I did not file a merge request because there is not much to merge. [1] https://aur.archlinux.org/account/haawda/ [2] https://aur.archlinux.org/pkgbase/lilypond-devel-docs/
