// RECORDING USER METRICS FOR FLAGS:
// -----------------------------------------------------------------------------
// The first line of the entry is the internal name.
//
// To add a new entry, add to the end of kFeatureEntries. There are two
// distinct types of entries:
// . SINGLE_VALUE: entry is either on or off. Use the SINGLE_VALUE_TYPE
//   macro for this type supplying the command line to the macro.
// . MULTI_VALUE: a list of choices, the first of which should correspond to a
//   deactivated state for this lab (i.e. no command line option).  To specify
//   this type of entry use the macro MULTI_VALUE_TYPE supplying it the
//   array of choices.
// See the documentation of FeatureEntry for details on the fields.
//
// Usage of about:flags is logged on startup via the "Launch.FlagsAtStartup"
// UMA histogram. This histogram shows the number of startups with a given flag
// enabled. If you'd like to see user counts instead, make sure to switch to
// to "count users" view on the dashboard. When adding new entries, the enum
// "LoginCustomFlags" must be updated in histograms.xml. See note in
// histograms.xml and don't forget to run AboutFlagsHistogramTest unit test
// to calculate and verify checksum.
//
// When adding a new choice, add it to the end of the list.
