+=================================================================
+Logtalk - Object oriented extension to Prolog
+Release 2.8.4
+
+Copyright (c) 1998-2001 Paulo Moura.  All Rights Reserved.
+=================================================================
+
+This folder contains several examples of Logtalk programs. Most of 
+these examples need objects, protocols and categories that are
+defined in the Logtalk standard library or in other examples, so 
+you should load them first (see the NOTES file inside each example 
+folder).
+
+Some examples may redefine objects already loaded from other examples.
+You may want to restart Logtalk after trying each example.
+
+Some of the examples code have been adopted from public available 
+Prolog code and from known Prolog text books and are copyrighted by 
+the respective authors.
+
+These are programming examples, meaning that you should look at the 
+source files to fully understand them.
+
+All examples are formatted using four spaces tabs.
+
+
