Hi Rudolf, thank you for your suggestion.
I'm on linux but I'd prefer not to use this method, because I use context
both from the command line and from my editor (emacs with auctex) and I
have scripts that change my environment to be able to switch between
different context versions (lmtx, texlive, ...). In any case, I'll think
about this solution and it could be useful to other people, too.
