+;; This file provides `guix-define-popup' macro which is just an alias
+;; to `magit-define-popup'.  According to the manual (info
+;; "(magit-popup) Defining prefix and suffix commands") `magit-popup'
+;; library will eventually be superseded by a more general library.

+
+(require 'magit-popup)

+(defalias 'guix-define-popup 'magit-define-popup)
