emacs-debbugs 0.9 Access the Debbugs bug tracker in Emacs

This package lets you access the GNU Bug Tracker from within Emacs.

For instance, it defines the command M-x debbugs-gnu for listing bugs, and the command M-x debbugs-gnu-search for bug searching. If you prefer the listing of bugs as TODO items of org-mode, you could use M-x debbugs-org and related commands.

A minor mode debbugs-browse-mode let you browse URLs to the GNU Bug Tracker as well as bug identifiers prepared for bug-reference-mode.
