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: | |
5825e5b2 | 15 | # first line of the message is who to CC, |
f3d9f354 | 16 | # and second line is the subject of the message. |
