Usage:
  Enables the use of multipart/form-data for posting forms

Inspirations:
  Upload files in python:
    http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/146306
  urllib2_file:
    Fabien Seisen: <fabien@seisen.org>

Example:
  import MultipartPostHandler, urllib2, cookielib

  cookies = cookielib.CookieJar()
  opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),
                                MultipartPostHandler.MultipartPostHandler)
  params = { "username" : "bob", "password" : "riviera",
             "file" : open("filename", "rb") }
  opener.open("http://wwww.bobsite.com/upload/", params)

Further Example:
  The main function of this file is a sample which downloads a page and
  then uploads it to the W3C validator.
