<!--
This is a review tool for our screenshot-based layout tests. It is specific to
our tests and internal test infrastructure in that it lists the names of all
screenshot tests and all WebDriver platforms in our test lab. Our layout tests
only run when the browser is connected via WebDriver, and test runs in
environments other than our lab may produce output in different folders than
those listed here.
