+
+;;; Commentary:
+
+;; This file adds support for `fontspec.sty' version 2.6a.  Starting
+;; with `fontspec.sty' v2.4, the order of mandatory font names and
+;; optional font features in related macros has changed, i.e. optional
+;; argument comes after the mandatory one.  This change is now (April
+;; 2017) implemented in this file.  Fontification support retains
+;; backward compatibilty.
