       revtwoway - Reverse strings sample two-way processor extension

SYNOPSIS

       @load "revtwoway"

       BEGIN {
           cmd = "/magic/mirror"
           print "hello, world" |& cmd

DESCRIPTION

       The revtwoway extension adds a simple two-way processor that reverses the characters in each line sent to
       it for reading back by the AWK program.  It's main purpose is to show how to write a  two-way  extension,
       although it may also be mildly amusing.
