"""Provide and email interface to the distributed bugtracker Bugs
Everywhere. Recieves incoming email via procmail and allows users to
select actions with their subject lines. Subject lines follow the
format
[be-bug] command (options) (args)
With the body of the email being used as the final argument for the
commands "new" and "comment", and ignored otherwise. The options and
arguments are split on whitespace, so don't use whitespace inside a
single argument.
Eventually we'll commit after every message.
