This is the else part of the script (modified from Hans ruby code to 
vimL). I tested it on the sources of the manuals, and the only thing 
that it could not detect correctly was metafun/mfun-ef.tex. Looking at 
that file, I do not think that it contains any context specific 
keyword.

Can others test on their context projects and see if this works 
correctly. I do not know the itnernational alternatives of all the 
commands. If your document uses any of those, let me know. Also check 
your latex documents to see that the script does not recognise it as 
context.

To run the script, save it as identify.vim . Inside vim,
:source identify.vim
:cd directory containing tex files
:argadd *.tex
:redir @a
:argdo call Identify_ConTeXt()
:redir END
:e temp_file
:put a

Now you have all the vim messages in temp_file

:g!/ConTeXt/d

Get rid of lines not containing context.

The message format from the script is
filename ConTeXt not detected/ detected at line ... format (en|nl|de|it)

Here is the script
