 // RECORDING USER METRICS FOR FLAGS:
 // -----------------------------------------------------------------------------
 // The first line of the experiment is the internal name. If you'd like to
 // gather statistics about the usage of your flag, you should append a marker
 // comment to the end of the feature name, like so:
 //   "my-special-feature",  // FLAGS:RECORD_UMA
 //
 // After doing that, run //chrome/tools/extract_actions.py (see instructions at
 // the top of that file for details) to update the chromeactions.txt file, which
 // will enable UMA to record your feature flag.
