48   * A TestSuite which will run a Groovy unit test case inside any Java IDE
49   * either as a unit test case or as an application.
50   * <p/>
51   * You can specify the GroovyUnitTest to run by running this class as an appplication
52   * and specifying the script to run on the command line.
53   * <p/>
54   * <code>
55   * java groovy.util.GroovyTestSuite src/test/Foo.groovy
56   * </code>
57   * <p/>
58   * Or to run the test suite as a unit test suite in an IDE you can use
59   * the 'test' system property to define the test script to run.
60   * e.g. pass this into the JVM when the unit test plugin runs...
61   * <p/>
