# 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. |
