Deprecated since release 2.3.
The email package should be used in
preference to the MimeWriter module. This
module is present only to maintain backward
This module defines the class MimeWriter. The
MimeWriter class implements a basic formatter for creating
MIME multi-part files. It doesn't seek around the output file nor
does it use large amounts of buffer space. You must write the parts
out in the order that they should occur in the final
file. MimeWriter does buffer the headers you add, allowing you
to rearrange their order.
Return a new instance of the MimeWriter class. The only
argument passed, fp, is a file object to be used for
writing. Note that a StringIO object could also be used.
