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.
