- * This file is the entrypoint of the dart test suite.  This suite is used
- * to test:
- *
- *     1. the dart vm
- *     2. the dart2js compiler
- *     3. the static analyzer
- *     4. the dart core library
- *     5. other standard dart libraries (DOM bindings, ui libraries,
- *            io libraries etc.)
- *
- * This script is normally invoked by test.py.  (test.py finds the dart vm
- * and passes along all command line arguments to this script.)
- *
- * The command line args of this script are documented in
- * "tools/testing/dart/test_options.dart"; they are printed
- * when this script is run with "--help".
- *
- * The default test directory layout is documented in
- * "tools/testing/dart/test_suite.dart", above
- * "factory StandardTestSuite.forDirectory".
