listener

A listener can either be a function or an object containing a handleEvent interface.

events.on("user:log", function(username){
  model.set({
    username : username
  })
})

// or

var model = model
  .extend({
    getDefaults : function(){
      return {
        username : ""
      }
    },
    handleEvent : function(username){
      this.set({
        username : username
      })
    }
  })
  .create()
events.on("user:log", model)

// or

var model = model
  .extend({
    getDefaults : function(){
      return {
        username : "",
        isThere : true
      }
    },
    handleEvent : {
      "user:log" : function(username){
        this.set({
          username : username
        })
      },
      "user:leave" : function(){
        this.set({
          isThere : false
        })
      }
    }
  })
  .create()

events.on("user:log", model)

chainable, returns this

.emit(type[, args …])

Triggers synchronously the type events, and passes args… as arguments for the listeners.

returns true if any callback has been executed returns false otherwise
