//   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

//   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.
