+## Purpose
+# This file is executed by ifupdown in pre-up, post-up, pre-down and
+# post-down phases of network interface configuration. It allows
+# ifup(8), and ifdown(8) to manage wpa_supplicant(8) and wpa_cli(8)
+# processes running in daemon mode.
+#
+# /etc/wpa_supplicant/functions.sh is sourced by this file.
+#
+# This file is provided by the wpasupplicant package.
