# SYNOPSIS
#
# AX_NEED_AWK
#
# DESCRIPTION
#
# Check if an awk implementation is available. Bail-out if not found.
#
# 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.
