Hello,
I use Emacs as an editor and I compile my files with LuaLaTeX by adding the following lines to the end of the file:

%%% Local Variables:
%%% Mode: LaTeX
%%% LaTeX-command "LuaLaTeX-shell-escape"
%%% End:

I discovered ConTeXt, and I would like to know which lines to add to the end of files.
Thank you.
