+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.
