Lilyglot is an extension for LilyPond that facilitates multilingual texts for use in header variables, instrument names, articulations, tempo specifications, marks, TOC, etc. A multilingual text is identified by a symbolic name. The actually used text corresponds to the selected lilyglot language. This is independent of the language selected for music entry.
Lilyglot requires LilyPond version 2.22.0 or higher.
