Hi Hans,

thank you, I was rather looking for some unified way of identifying the
lua interpreter that would work with the 4 machines I mentioned. Nevermind,
individually testing, while it does not really look good, works fine:

···8<··········································································
if context then
  interp = "context"
elseif arg[0] == "luatex" then
  interp = "luatex"
elseif arg[-1] == "texlua" then
  interp = "texlua"
else
  interp = "plainlua"
end
···8<··········································································
