By default PubSubJS can be used in any browser or CommonJS environment, including [node](http://nodejs.org). Additionally, PubSubJS can be built specifically for jQuery using Rake.

$ rake jquery

or using Grunt

$ grunt jquery

Produces jquery.pubsub.js

var topic = 'greeting',

data = 'world',

subscriber = function sayHello( data ){

console.log( 'hello ' + data );

};

var token = $.pubsub('subscribe', topic, subscriber );

$.pubsub('unsubscribe', token); // remove a specific subscription

$.pubsub('unsubscribe', subscriber); // remove all subscriptions for subscriber

$.pubsub('publish', topic, data);

$.pubsub('publishSync', topic, data);

In the jQuery build, the global ```PubSub``` global is still available, so you can mix and match both ```Pubsub``` and ```$.pubsub``` as needed.
