+;;; Commentary:
+;;
+;; Blacken uses black to format a Python buffer.  It can be called
+;; explicitly on a certain buffer, but more conveniently, a minor-mode
+;; 'blacken-mode' is provided that turns on automatically running
+;; black on a buffer before saving.
+;;
+;; Installation:
+;;
+;; Add blacken.el to your load-path.
+;;
+;; To automatically format all Python buffers before saving, add the
+;; function blacken-mode to python-mode-hook:
+;;
+;; (add-hook 'python-mode-hook 'blacken-mode)
+;;
