Package channel implements the server side of App Engine's Channel API.

Create creates a new channel associated with the given clientID, which must be unique to the client that will use the returned token.

token, err := channel.Create(c, "player1")
if err != nil {
	// handle error
// return token to the client in an HTTP response

Send sends a message to the client over the channel identified by clientID.

channel.Send(c, "player1", "Game over!")
