# bashbug - create a bug report and mail it to the bug address
#
# The bug address depends on the release status of the shell.  Versions
# with status `devel', `alpha', `beta', or `rc' mail bug reports to
# chet@cwru.edu and, optionally, to bash-testers@cwru.edu.
# Other versions send mail to bug-bash@gnu.org.

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.
