+TechSupport - the DodgySoft Technical support system.
+
+This project is part of the material for the book
+
+   Objects First with Java - A Practical Introduction using BlueJ
+   Sixth edition
+   David J. Barnes and Michael Kölling
+   Pearson Education, 2016
+
+This project is discussed in chapter 6.
+
+This project aims to implements a technical support system for customers of 
+the DodgySoft software company. Users can describe their software problems and 
+get advice instantly!
+
+The idea is based on Eliza - a famous program described by Joseph Weizenbaum 
+in 1966. (Do a web search for "Eliza" and "Weizenbaum" if you want to know 
+more about this.)
+
+In fact, it is much more primitive than Eliza. But that's enough to match the 
+quality of many software companies' technical support advice...  ;-)
+
+To start this program, create a SupportSystem object and execute the "start" 
+method.
+
+Then start describing your problem by typing in the terminal window.
+
+The purpose of this project is to demonstrate and study library classes, such 
+as ArrayList, HashMap, HashSet, and Random.
+
+This project is only a first, rudimentary step towards the full solution.
