SYNOPSIS

sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
by giving a comma separated list of bug-report-email-addresses.
If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.
