+%% Test script for legacy OOP.
+%% Requires the path to contain the test classes.
+%%
+%% Note: This script and all classes are also intended to run
+%%       in MATLAB to test compatibility.  Don't break that!
+%%
+%%       Note(JBect, 2013/01/27) : in order to ease to process of testing
+%%       Matlab compatibility, the syntax assert(observed, expected) should
+%%       be avoided. I use assert(isequal(observed, expected) instead.
+%%
+%% To Do:  This script tests to ensure that things done correctly work
+%%         corrrectly.  It should also check that things done incorrectly
+%%         error properly.
+%%
+%% The classes used for the tests reside in the test directory.
+%%
+%% The classes provide the ability to test most of the major features
+%% of the legacy OOP facilities.  There are a number of classes, mostly
+%% kind of the same, that create a hierarchy.
+
+%% Test the Snork class.  The Snork class has a number of the standard
+%% methods that the others don't so we can test indexing and other
+%% features.
