+# SYNOPSIS
+#    dconf_policy_a11y.sh [ENFORCE]
+#
+# DESCRIPTION
+#    This script installs a policy that forces the Universal Access menu to be
+#    shown at all times.
+#
+#    Use a boolean to decide whether to enforce or not. An unchecked box will
+#    remove the policy and a checked one will enforce it.
