<tt>A few versions ago in Fedora (v15), the PackageKit daemon
doesn't work in XFCE anymore, so I wrote a small Perl Gtk2 app
that would watch for available yum updates and put a tray icon in
your Notification Area to notify you (Perl version: </tt>

</tt><tt><br>
</tt><tt>I've recently ported the app over to Python 2. I heard that
the Fedora XFCE spins are going to drop Perl (or at least severely
shrink the Perl installation) to save space, so the Python version
of this app will be useful going forward (on my current Fedora 18
XFCE desktops, pygtk2 was already installed, which is pretty much
this script's only dependency). :)</tt><tt><br>

- this code is open domain and you can do with it what you please.
It would be neat if this could be shipped with future releases of
the Fedora XFCE spin.</tt><tt><br>

</tt><tt>Here's the source code here also, in case the links are
down. This version has only been lightly tested (I literally just
finished writing it an hour ago), but seems to work so far.</tt><tt><br>

pyupdatesd: A simple yum update checker.
This script will watch for available yum updates and show a Gtk2 tray icon and
notification pop-up when updates become available.
This is intended for desktop environments like XFCE that don't have a native
PackageKit update watcher.
Set this script to run on session startup, and it will check for updates every
15 minutes (by default; this is configurable in the source code).
This software is open domain and may be freely modified and distributed.
Requires: pygtk2
