-"""Watch a few mbox folders from Thunderbird and notify when there are
-new messages. This should be a builtin feature in Thunderbird, but it
-is not.
-
-It takes a configuration file as first argument written in YAML. It
-should look like this::
-
-    root: ~/.thunderbird/something-default/ImapMail/imap.example.com
-    folders:
-      - INBOX
-      - Notifications/GitHub
-
-"""
-
-# This is quite basic. Notably, it relies on some quirks of the
-# Thunderbird mbox format where the From line contains a timestamp of
-# the received message and therefore can be used as a watermark as
-# long as we don't receive more than 1 message per second.
