8 # Ported to support git "mbox" format files by Ryan Anderson <ryan@michonline.com>
9 #
10 # Sends a collection of emails to the given email addresses, disturbingly fast.
11 #
12 # Supports two formats:
13 # 1. mbox format files (ignoring most headers and MIME formatting - this is designed for sending patches)
14 # 2. The original format support by Greg's script:
15 # first line of the message is who to CC,
16 # and second line is the subject of the message.
