"Usage: $PROGNAME
  Generate a diff for an NMU and mail it to the BTS.
  $PROGNAME options:
    --new             Submit a new bug report rather than sending messages
                      to the fixed bugs (default if more than one bug being
                      closed or no bugs being closed)
    --old             Send reports to the bugs which are being closed rather
                      than submit a new bug (default if only one bug being
                      closed)
    --sendmail=SENDMAILCMD
                      Use SENDMAILCMD instead of \"/usr/sbin/sendmail -t\"
    --mutt            Use mutt to mail the message (default)
    --no-mutt         Mail the message directly, don't use mutt
    --from=EMAIL      Use EMAIL address for message to BTS; defaults to
                      value of DEBEMAIL or EMAIL
    --delay=DELAY     Indicate that the NMU has been uploaded to the
                      DELAYED queue, with a delay of DELAY days; defaults
                      to a placeholder value of "XX". If DELAY is 0 then
                      no reference is made to the DELAYED queue.
    --no-delay        Equivalent to \"--delay=0\"
    --no-conf, --noconf
                      Don't read devscripts config files;
                      must be the first option given
    --help, -h        Show this help information.
    --version         Show version and copyright information.
