stderr from an io.popen ?

[pj@...]

Greetings.

Is it possible to
  local pipe = io.popen(command, 'rb')
and then get access to any stderr output it may produce ?

This comes from trying to translate from Python:
  pipe = subprocess.Popen(command, shell=True,
    stdout=subprocess.PIPE, stderr=subprocess.PIPE)
  midi = pipe.stdout.read()
  msg  = pipe.stderr.read()
