///     2. The dart2js compiler
///     3. The static analyzer
///     4. The Dart core library
///     5. Other standard dart libraries (DOM bindings, UI libraries,

///     6. The Dart specification parser.

/// The command line args of this script are documented in "test_options.dart".
/// They are printed when this script is run with "--help".
///
/// The default test directory layout is documented in "test_suite.dart", above
