Can texexec enable write18 at runtime

Can texexec enable write18 at runtime

[David Arnold]

All,

In GWTeX, I could turn on write18 here:

% Enable \write18 (run shell processes from within TeX job)
% Set to t if needed
% (I think this might have security implications, especially if you
% run tex jobs as administrator, so I keep it turned off by default
shell_escape = f

But, because of security, I am wondering if I can leave this as is  
and use texexec to enable write18 at runtime.

Is there a switch for this?

I know you can do it with pdflatex with:

pdflatex --shell-escape

You can use --passon

   texexec --passon='--shell-escape'

the latest version of pdftex can determine if write18 is enables so we 
can indeed make context/texexec a bit more clever; however, i'm always a 
bit carefull with such things because i want to make sure that users run 
recent binaries
