How to send the [PATCH 0/x] kind of emails?

Dec. 12, 2014

      How does one send this kind of summary email? Is it generated manually
or through some git format-patch/send-email foo magic?

I have 4 patches that I have to submit. I'd like to send a summary
email (0/4) explaining the changes.

Thanks,
