NAME

       revoutput - Reverse output strings sample extension

SYNOPSIS

       @load "revoutput"

       BEGIN { REVOUT = 1 }    # Reverse all output strings

DESCRIPTION

       The  revoutput  extension  adds a simple output wrapper that reverses the characters in each output line.
       It's main purpose is to show how to write an output wrapper, although it may be mildly  amusing  for  the
       unwary.

EXAMPLE

       @load "revoutput"

       BEGIN {
           REVOUT = 1
           print "hello, world" > "/dev/stdout"
       }

       The output from this program is:

       dlrow ,olleh

BUGS

       This extension does not affect the default standard output.
