ABSTRACT

This book is no longer up-to-date. No book on computers ever is. While I am writing, developments in computer technology and software design continue, many of them still invisible, because they are no more than an idea in someone’s mind. Although they were the newest at the time of this writing and not yet reviewed anywhere else, the programs described here are only a beginning. They will undoubtedly change and improve, and new ones will appear. Yet this book is not completely time-bound.
