+
+;;; Commentary:
+
+;; A major mode for editing Git commit messages.
+
+;; * Formatting
+;;
+;; Highlight the formatting of git commit messages and indicate errors according
+;; to the guidelines for commit messages (see
+;; http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html).
+;;
+;; Highlight the first line (aka "summary") specially if it exceeds 54
+;; characters.
+;;
+;; Enable `auto-fill-mode' and set the `fill-column' to 72 according to the
+;; aforementioned guidelines.
+
+;; * Headers
+;;
+;; Provide commands to insert standard headers into commit messages.
+;;
+;; - C-c C-x s or C-c C-s inserts Signed-off-by (`git-commit-signoff').
+;; - C-C C-x a inserts Acked-by (`git-commit-ack').
+;; - C-c C-x t inserts Tested-by (`git-commit-test').
+;; - C-c C-x r inserts Reviewed-by (`git-commit-review').
+;; - C-c C-x o inserts Cc (`git-commit-cc').
+;; - C-c C-x p inserts Reported-by (`git-commit-reported').
+
+;; * Committing
+;;
+;; C-c C-c finishes a commit.  By default this means to save and kill the
+;; buffer.  Customize `git-commit-commit-function' to change this behaviour.
+;;
+;; Check a buffer for stylistic errors before committing, and ask for
+;; confirmation before committing with style errors.
+
+;; * Magit integration
+;;
+;; Overwrite `magit-log-edit-mode' to provide font locking and header insertion
+;; for Magit.
+;;
+;; Change the keymap of `magit-log-edit-mode' to use the header insertion of
+;; `git-commit-mode'.
