       nmudiff - email an NMU diff to the Debian BTS


       nmudiff [options]


       nmudiff  should  be  run  in  the source tree of the package being NMUed, after the NMU is
       built. It assumes that the source packages (specifically, the .dsc and  any  corresponding
       tar  and  diff files) for both the previous version of the package and the newly built NMU
       version are in the parent directory. It then uses debdiff to generate a diff  between  the
       previous  version  and  the  current  NMU,  and  either  runs  mutt  or  an  editor (using
       sensible-editor) so that the mail  message  (including  the  diff)  can  be  examined  and
       modified; once you exit the editor the diff will be mailed to the Debian BTS.

       The default behaviour is that if exactly one bug is closed by this NMU, then that bug will
       be mailed, otherwise a new bug will be  submitted.   This  behaviour  may  be  changed  by
       command line options and configuration file options.


       --new  Instead  of  mailing  the bug reports which are to be closed by this NMU, a new bug
              report is submitted directly to the BTS.

       --old  Send the bug report to all of the bugs which are being closed by this  NMU,  rather
              than  opening  a  new  bug  report.  This option has no effect if no bugs are being
              closed by this NMU.

       --mutt Use mutt(1) for editing and sending the message to  the  BTS  (default  behaviour).
              This can be controlled using a configuration file option (see below).

              Use  sensible-editor(1)  to  edit  the  message  and  then  mail  it directly using
              /usr/bin/sendmail.  This can be controlled using a configuration file  option  (see

       --sendmail SENDMAILCMD
              Specify the sendmail command.  The command will be split on white space and will be
              interpreted by the shell.  Default is /usr/sbin/sendmail.  The -t  option  will  be
              automatically  added  if the command is /usr/sbin/sendmail or /usr/sbin/exim*.  For
              other mailers, if  they  require  a  -t  option,  this  must  be  included  in  the
              SENDMAILCMD, for example: --sendmail="/usr/sbin/mymailer -t".  This can also be set
              using the devscripts configuration files; see below.

       --from EMAIL
              If using the sendmail (--no-mutt) option, then the email to the BTS  will  be  sent
              using  the  name and address in the environment variables DEBEMAIL and DEBFULLNAME.
              If these are not set, then the variables EMAIL  and  NAME  will  be  used  instead.
              These can be overridden using the --from option.  The program will not work in this
              case if an email address cannot be determined.

       --delay DELAY
              Indicate in the generated mail that the NMU has been uploaded to the DELAYED queue,
              with  a  delay  of DELAY days.  The default value is XX which adds a placeholder to
              the e-mail.  A value of 0 indicates that the upload has not been sent to a  delayed
              queue.  This can also be set using the devscripts configuration files; see below.

       --no-delay, --nodelay
              Equivalent to --delay 0.

       --no-conf, --noconf
              Do  not  read  any  configuration files.  This can only be used as the first option
              given on the command-line.

       --help Display a help message and exit successfully.

              Display version and copyright information and exit successfully.


       The two configuration files /etc/devscripts.conf and ~/.devscripts  are  sourced  in  that
       order  to  set  configuration  variables.   Command  line  options can be used to override
       configuration file settings.  Environment variable settings are ignored for this  purpose.
       The currently recognised variables are:

              If this is set to a number, e-mails generated by nmudiff will by default mention an
              upload to the DELAYED queue, delayed for the specified number of days.  The value 0
              indicates that the DELAYED queue has not been used.

              Can  be  yes (default) or no, and specifies whether to use mutt to compose and send
              the message or not, as described above.

              This option controls whether a new bug report is made, or whether the diff is  sent
              to  the  bugs  closed  by  this  NMU.   Can  be maybe (default), which sends to the
              existing bug reports if exactly one bug is being closed; yes, which always  creates
              a  new  report,  or  no, which always sends to the reports of the bugs being closed
              (unless no bugs are being closed, in which case a new report is always made).

              If this is set, specifies a sendmail command to use instead of  /usr/sbin/sendmail.
              Same as the --sendmail command line option.
