1 Appendix A The Evolution of the 'awk' Language
1 **********************************************
1 
1 This Info file describes the GNU implementation of 'awk', which follows
1 the POSIX specification.  Many longtime 'awk' users learned 'awk'
1 programming with the original 'awk' implementation in Version 7 Unix.
1 (This implementation was the basis for 'awk' in Berkeley Unix, through
1 4.3-Reno.  Subsequent versions of Berkeley Unix, and, for a while, some
1 systems derived from 4.4BSD-Lite, used various versions of 'gawk' for
1 their 'awk'.)  This major node briefly describes the evolution of the
1 'awk' language, with cross-references to other parts of the Info file
1 where you can find more information.
