#
# 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.

   --compose      Use \$EDITOR to edit an introductory message for the
                  patch series.

   --subject      Specify the initial "Subject:" line.
                  Only necessary if --compose is also set.  If --compose
		  is not set, this will be prompted for.
