Hi Elie, In luaotfload I copied the lua files from ConTeXt and renamed them (with a prefix)
Oh yes, now I remember that discussion with you. Sorry. Well, the situation has changed: as I understand it, Hans is now auto-creating a standalone luatex-fonts.tex that will not depend on the rest of ConTeXt. At least that is what I asked for. Anyway, having two implementations is necessary because ConTeXt's implementation is not compatible with luatextra. Hmm.
