       revtwoway - Reverse strings sample two-way processor extension

       @load "revtwoway"

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

       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 mildy amusing.
