-# Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
-#
-# Sends a collection of emails to the given email addresses, disturbingly fast.
-#
-# Supports two formats:
-# 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)
-# 2. The original format support by Greg's script:
-# first line of the message is who to CC,
-# and second line is the subject of the message.
