revtwoway - Reverse strings sample two-way processor extension
cmd = "/magic/mirror"
print "hello, world" |& cmd
cmd |& getline result
adds a simple two-way processor that reverses the characters
in each line sent to it for reading back by the AWK program.
Its main purpose is to show how to write a two-way extension, although
it may also be mildy amusing.
