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. | |
