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.
