| # 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. |
