""" 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.
