   5 """Runs Octane 2.0 javascript benchmark.
   6
   7 Octane 2.0 is a modern benchmark that measures a JavaScript engine's performance
   8 by running a suite of tests representative of today's complex and demanding web
   9 applications. Octane's goal is to measure the performance of JavaScript code
  10 found in large, real-world web applications.
  11 Octane 2.0 consists of 17 tests, four more than Octane v1.
