[NTG-context] pdfcrop with context

Hello, basically my question is to know if there is a way to use ConTeXt to
perform the functions that pdfcrop does.

pdfcrop: A Perl script that can either trim pages of any whitespace border,
or trim them of a fixed border

The \clip command works on a PDF file.

But you need to give it exact measurements.

There is an old perl script `pdftrimwhite` which will do the calculations for you.

    mtxrun --script pdftrimwhite 

I hadn't used it for a while and I tried it and it fails because it is still calling context using texexec:

sub RunTeX
  { if ($UsePlain)
      { $result = `pdftex -prog=pdftex -fmt=plain -int=batchmode $tempfile` }
    else
      { $result = `texexec --batch --once --purge $tempfile` }
    print $result if $Verbose ; $results .= "$result\n" }


I suspect that changing `texexec` to `context` should make it work with the current installation as well.
