beyondcode的确认电子邮件包特征是什么？

Question

在github上的beyondcode's confirm email软件包页面中，它说：

In order to make use of the email verification, replace the AuthenticatesUsers, 
RegistersUsers and the SendsPasswordResetEmails traits that come with Laravel, 
with the ones provided by this package.

但没有提供任何特征！他们是什么？
