   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.
