        Additionally, this method initializes the multi-part code, where the
        subtype parameter provides the multipart subtype, the boundary
        parameter may provide a user-defined boundary specification, and the
        plist parameter provides optional parameters for the subtype.  The
        optional argument, prefix, determines where the header is inserted;
        0 means append at the end, 1 means insert at the start. The default
        is to insert at the start.  Subparts should be created using the
        nextpart() method.
