maildirgtk.py

#! /usr/bin/python

# This is a class which watches a maildir for new messages. It uses the
# linux dirwatcher API (if available) to look for new files. The
# .messageReceived method is invoked with the filename of the new message,
# relative to the top of the maildir (so it will look like "new/blahblah").

# This form uses the Gtk event loop to handle polling and signal safety
