# 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.
