"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)
--mua=MUACMD Use MUACMD as Mail User Agent (such as \"thunderbird\")
--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
--no-pending, --nopending
Don't add the 'pending' tag
--non-dd, --nondd
Mention in the email that you require sponsorship.
--template=TEMPLATEFILE
Use content of TEMPLATEFILE for message.
--help, -h Show this help information.
--version Show version and copyright information.
