To decode the Subject =?iso-8859-2?Q?=... in email in python

[Dan Polansky]

When parsing messages using python's libraries email and mailbox, the
subject is often encoded using some kind of = notation. Apparently, the
encoding used in this notation is specified like =?iso-8859-2?Q?=... or
=?iso-8859-2?B?=. Is there a python library function to decode such a
subject, returning a unicode string? The use would be like

  human_readable = cool_library.decode_equals(message['Subject'])

Thank you, Dan
