// The test log collector uses Event Tracing for Windows to collect all LOG()
// events at all levels (including all VLOG levels) from Chrome, Chrome Frame,
// and the test executable itself for each test into a temporary log file. At
// the conclusion of each test, the contents of the log file are regurgitated to
// stderr iff the test failed. In any case, the log file is promptly deleted.
// Test executables that wish to benefit from the collector's features (to
// produce verbose logs on test failure to aid in diagnosing flaky and/or
// failing tests, for example) must install the collector via
// |InstallTestLogCollector| before running tests (via RUN_ALL_TESTS(),
// TestSuite::Run(), etc).
