  81 Bashbug is used to send mail to the Bash maintainers
  82 for when Bash doesn't behave like you'd like, or expect.
  83
  84 Bashbug will start up your editor (as defined by the shell's
  85 EDITOR environment variable) with a preformatted bug report
  86 template for you to fill in. The report will be mailed to the
  87 bash maintainers by default. See the manual for details.
  88
  89 If you invoke bashbug by accident, just quit your editor without
  90 saving any changes to the template, and no bug report will be sent.
