Hi Élie, thanks for the quick answer. I will simply follow TeX Live - that means the TeX and lua files will be in the respective collection package, I guess collection/texlive-music, and the binary gregorio will be in texlive-binaries, as with all binaries. Hope that suits you All the best Norbert --- PREINING, Norbert http://www.preining.info JAIST, Japan TeX Live & Debian Developer GPG: 0x860CDC13 fp: F7D8 A928 26E3 16A1 9FA0 ACF0 6CAC A448 860C DC13
