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