Internal Program Version: 2.0.1

This is the gawk-json part of gawkextlib.

The gawkextlib contains several shared library extension packages 
for gawk, as well as libgawkextlib containing some APIs that 
are useful for extension packages.  These extension libraries require 
the use of gawk (GNU Awk) version 4.1.1 or later, except for the select 
and json extensions, which are currently supported only by gawk 4.2 
(API version 2) and later.
