Hello,
As someone mentioned Python 3 here and on fedora-devel... here's a small patch
that gets metadata entries' has_key() out of the way of further has_key()
related changes.
So when previously one would do "entry.has_key(foo)", after this one should do
"foo in entry" instead.

From: =?utf-8?q?Ville=20Skytt=C3=A4?= <ville.sky...@iki.fi>
Date: Fri, 2 Oct 2009 00:25:43 +0300
Subject: [PATCH 6/6] Deprecate has_key() in favour of "in" for metadata entries.
As a side effect, entries are now iterable.
