I'm still trying to understand mime and multifiles,

can some one explain the purpose of the following lines of code in the 
12.10.2 MultiFile Example

data = StringIO.StringIO()

            submsg = mimetools.Message(file)
            try:
                data = StringIO.StringIO()
                mimetools.decode(file, data, submsg.getencoding())
            except ValueError:
                continue
            if submsg.gettype() == mimetype:
                break
        file.pop()
    return data.getvalue()



submsg = mimetools.Message(file)
        try:
            data = StringIO.StringIO()
            mimetools.decode(file, data, submsg.getencoding())
        except ValueError:
            continue
