 * Tool for running co19 tests. Used when updating co19.
 *
 * Currently, this tool is merely a convenience around multiple
 * invocations of test.dart. Long term, we hope to evolve this into a
 * script that can automate most of the tasks necessary when updating
 * co19.
 *
 * Usage:
 * [: ./tools/testing/bin/$OS/dart tools/testing/dart/co19_test.dart :]
