 /**
  * 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".
