// To add a new entry, add to the end of kFeatureEntries. There are four

// . ENABLE_DISABLE_VALUE: entry is either enabled, disabled, or uses the
// default value for this feature. Use the ENABLE_DISABLE_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.
// . FEATURE_VALUE: entry is associated with a base::Feature instance. Entry is
// either enabled, disabled, or uses the default value of the associated
// base::Feature instance. To specify this type of entry use the macro
// FEATURE_VALUE_TYPE supplying it the base::Feature instance.
// . FEATURE_WITH_PARAM_VALUES: a list of choices associated with a
// base::Feature instance. Choices corresponding to the default state, a
// universally enabled state, and a universally disabled state are
// automatically included. To specify this type of entry use the macro
// FEATURE_WITH_PARAMS_VALUE_TYPE supplying it the base::Feature instance and
// the array of choices.
//
// See the documentation of FeatureEntry for details on the fields.
//
// When adding a new choice, add it to the end of the list.
