 /**
  * 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 :]
