None of the above. I meant exactly what I said; making multipart/form-data
POST submissions programmatically using httplib and MimeWriter.

But thanks for the reply anyway.

I figured it out in the end, after some experimentation. The two libraries
don't work well together for various reasons. For intance, MimeWriter can't
provide a content-length, which POST requests require. Fortunately it's
trivial to write multipart MIME messages 'the long way'.

(Background; I'm working on a client-side web testing library that sits on
PyUnit, and which will soon be available at webunit.sourceforge.net)
