"""
Provide and email interface to the distributed bugtracker Bugs
Everywhere. Recieves incoming email via procmail. Provides an
interface similar to the Debian Bug Tracker. There are currently
three distinct email types: submits, comments, and controls. The
email types are differentiated by tags in the email subject. See
SUBJECT_TAG* for the current values.
Submit emails create a bug (and optionally add some intitial
comments). The post-tag subject is used as the bug summary, and the
email body is parsed for a pseudo-header. Any text after the
psuedo-header but before a possible line starting with BREAK is added
as the initial bug comment.
Comment emails...
Control emails...
Any changes made to the repository are commited after the email is
executed, with the email's post-tag subject as the commit message.
