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

///     6. The Dart specification parser.

/// This script is normally invoked by test.py. (test.py finds the Dart VM and

/// The command line args of this script are documented in "test_options.dart".

///
/// The default test directory layout is documented in "test_suite.dart", above
