If it's being written to stdout or stderr, you can capture those by
replacing subprocess.call() with:

	p = subprocess.Popen(<command>, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
	out, err = p.communicate()

out and err will be strings, containing the data written to stdout and
stderr respectively.
