/** @file
 * Unit tester
 * 
 * The heart and soul of HTML Purifier's correctness; anything and everything
 * is tested here! Arguments are specified like --arg=opt, allowed arguments
 * are:
 *   - flush, whether or not to flush definition caches before running
 *   - standalone, whether or not to test the standalone version
 *   - file (f), a single file to test
 *   - xml, whether or not to output XML
 *   - dry, whether or not to do a dry run
 *
 * If you're interested in running the test-cases, mosey over to
 * ../test-settings.sample.php, copy the file to test-settings.php and follow
 * the enclosed instructions.
 *
 * @warning File setup does not exactly match with autoloader; make sure that
 *          non-test classes (i.e. classes that are not retrieved using
 *          $test_files) do not have underscores in their names.
