poster provides a set of classes and functions to faciliate making HTTP POST
(or PUT) requests using the standard multipart/form-data encoding.

The modules in the Python standard library don't provide a way to upload large
files via HTTP without having to load the entire file into memory first.

poster provides support for both streaming POST requests as well as
multipart/form-data encoding of string or file parameters.
