\enableregime, \setupoutput

Is \setup too general (will it recognize any LaTeX document)?

I don't know how slow/fast the detection is since I only use short
files, but if you check the last few lines, \stoptext (together with
its international alternatives) isn't a bad idea.

Also, if you check the last few lines: emacs users usually put some
lines of code at the end to mark the document as being written in
ConTeXt.

A keyword like
set tex_preferred_dialect=latex/context :)

and then

if tex_preferred_dialect == context
    if the first few lines contain \documentclass or \documentstyle,
    declare it latex, otherwise ConTeXt
else
   [your script]:
   if the first line contains % tex= or any keywords that Hans sent
   or if the first six lines contain the keywords you suggested
(together with international alternatives)

(don't take that suggestion too seriously)
