+# SYNOPSIS
+#
+# AX_CHECK_AWK_OPERATOR_SQUARE([ACTION-IF-SUCCESS],[ACTION-IF-FAILURE])
+#
+# DESCRIPTION
+#
+# Check if AWK supports the '^' operator. If successful execute
+# ACTION-IF-SUCCESS otherwise ACTION-IF-FAILURE.
+#
+# This work is heavily based upon testawk.sh script by Heiner Steven.
+# You should find his script (and related works) at
+# <http://www.shelldorado.com/articles/awkcompat.html>. Thanks to
+# Alessandro Massignan for his suggestions and extensive nawk tests
+# on FreeBSD.
