@subsection Viewing Bugs within Emacs
Emacs has a nice minor mode called @code{bug-reference}, which, when
combined with @samp{emacs-debbugs} (the Emacs package), can be used to
open links such as @samp{<https://bugs.gnu.org/58697>} or
@samp{<https://issues.guix.gnu.org/58697>} as bug report buffers. From
there you can easily consult the email thread via the Gnus interface,
reply or modify the bug status, all without leaving the comfort of
Emacs! Below is a sample configuration to add to your @file{~/.emacs}
configuration file:
@lisp
