406 // feature flag), then update the <owner>s and <description> sections. Make sure
407 // to include the actions.xml file when you upload your code for review!
409 // After your feature has shipped under a flag, you can locate the metrics under
410 // the action name AboutFlags_internal-action-name. Actions are recorded once
411 // per startup, so you should divide this number by AboutFlags_StartupTick to
412 // get a sense of usage. Note that this will not be the same as number of users
413 // with a given feature enabled because users can quit and relaunch the
414 // application multiple times over a given time interval. The dashboard also
415 // shows you how many (metrics reporting) users have enabled the flag over the
416 // last seven days. However, note that this is not the same as the number of
417 // users who have the flag enabled, since enabling the flag happens once,
418 // whereas running with the flag enabled happens until the user flips the flag
419 // again.
421 // To add a new experiment add to the end of kExperiments. There are two
422 // distinct types of experiments:
423 // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE
424 // macro for this type supplying the command line to the macro.
425 // . MULTI_VALUE: a list of choices, the first of which should correspond to a
426 // deactivated state for this lab (i.e. no command line option). To specify
427 // this type of experiment use the macro MULTI_VALUE_TYPE supplying it the
428 // array of choices.
429 // See the documentation of Experiment for details on the fields.
431 // Command-line switches must have entries in enum "LoginCustomFlags" in
432 // histograms.xml. See note in histograms.xml and don't forget to run
433 // AboutFlagsHistogramTest unit test to calculate and verify checksum.
