+
+;;; Commentary:
+
+;; This is a forward compatibility package, which provides (a subset of) the
+;; features of the cl-lib package introduced in Emacs-24.3, for use on
+;; previous emacsen.
+
+;; Make sure this is installed *late* in your `load-path`, i.e. after Emacs's
+;; built-in .../lisp/emacs-lisp directory, so that if/when you upgrade to
+;; Emacs-24.3, the built-in version of the file will take precedence, otherwise
+;; you'll quickly get recursive-load errors.
+
+;; This code is largely copied from Emacs-24.3's cl.el, with the alias bindings
+;; simply reversed.
+
+;;; Code:
+
+(require 'cl)
+
+;; Some of Emacs-24.3's cl.el definition are not just aliases, because either
+;; the feature was dropped from cl-lib.el or because the cl-lib version is
+;; not fully compatible.
+;; Let's just not include them here, since it is very important that if code
+;; works with this cl-lib.el it should also work with Emacs-24.3's cl-lib.el,
+;; whereas the reverse is much less important.
