Introduction.

This guide is intended for anyone who is interested in improving performance and responsiveness in their Delphi applications by using threads. It covers a range of topics from absolute beginner to intermediate level, and some of the real world examples raise issues bordering on the advanced. It assumes that the reader has a reasonable knowledge of Object Pascal programming, including simple object orientation, and a working understanding of event based programming.
