import "appengine/channel"
Introduction
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!")
