An extremely simple way to send Yo notifications in your terminal.
$ npm install -g heyo
$ heyo register <username> register a new Yo account
$ heyo <username> send a Yo to <username>
$ heyo switch <username> switch to send from <username>
$ heyo list list accounts registered with heyo
heyo is a CLI built on the excellently named yoplait wrapper. Registering a user with heyo will create a new account with a randomly generated UDID and store it internally.
