xPL Gmail Notifier

I've taken the Python source for Gmail Notifier and modified it (with code from the Python xPL Toolkit) to issue an xPL osd.basic message when it encounters a new email message. Since it's Python, you can easily modify notifier.py to change the xPL message to whatever you want. I'll leave that as an exercise to you. A few things, before you grab the zip file (comments I left in the code):

# * changes to remove the tray icon as pytrayicon is not
#   supported in windows
# * removed the popup that notifies of a new email
# * added xPL support to generate osd.basic messages
#   containing sender of new email
# * since there's no tray icon, you cannot reconfigure from the gui
#   after you've configured once before.  therefore if you need to 
#   change your settings again, edit .notifier.conf located in
#   c:\documents and settings\your_login

You'll need to install a few things first besides Python - PyGTK and GTK. Go here and follow the directions for PyGTK for Microsoft Windows. Finally, here's my zip file.
