Tests are now declared with detailed descriptions and a short test name:

	BEGIN_TEST(the_test0, "this is an example test that does something")
		...
	END_TEST

Modules are declared through a simple macro interface:

	BEGIN_MODULE(mod_name)
		ADD_TEST(the_test0);
		...
	END_MODULE

Error messages when tests fail have been greatly improved.
