;;; Commentary:
;; Provides support for the :diminish keyword, which is made available
;; by default by requiring `use-package'. Using it requires the
;; `diminish' package to be installed (available on GNU ELPA).
;;
;; See the `use-package' info manual for more information.
;;; Code:
(require 'use-package-core)
(defun use-package-normalize-diminish (name label arg &optional recursed)
"Normalize the arguments to diminish down to a list of one of two forms:
