/**
 * 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 dartc 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 passses along all command line arguments to this script.)
 *
 * The command line args of this script are documented in
 * "tools/testing/test_options.dart".
