Drush: Told to use "features_export" instead of "features_add"

Plastico ~/Sites/hbosscs.test> drush fa hboss_cs
features_add is DEPRECATED.
Calling features_export instead.
No feature name given.                                                                                                  [error]

Invalid command features_export.                                                                                        [error]

The takeaway is that I was confused when told to use "features_export" instead of "features_add", when what I actually should have been told was to use "features-export" instead of "features-add". The old "features-add" also seems to be lying about not specifying a feature name.
