def visDQMUpload.encode	(		args,

  Encode form (name, value) and (name, filename, type) elements into
  multi-part/form-data. We don't actually need to know what we are
  uploading here, so just claim it's all text/plain.

def visDQMUpload.marshall	(		args,
			files,

  Marshalls the arguments to the CGI script as multi-part/form-data,
  not the default application/x-www-form-url-encoded.  This improves
  the transfer of the large inputs and eases command line invocation
  of the CGI script.
