 * #include <cppunit/CompilerOutputter.h>
 * #include <cppunit/TestResult.h>
 * #include <cppunit/TestResultCollector.h>

 * 
 *   // Create the event manager and test controller
 *   CppUnit::TestResult controller;
 * 
 *   // Add a listener that colllects test result
 *   CppUnit::TestResultCollector result;
 *   controller.addListener( &result );        
 * 
 *   // Add a listener that print dots as test run.
 *   CppUnit::TextTestProgressListener progress;
 *   controller.addListener( &progress );

 *   // Add the top suite to the test runner
 *   CppUnit::TestRunner runner;
