This package is published through NPM under the name 'deferredjs':
$ npm install deferredjs
Once installed, simply Deferred = require("deferredjs").Deferred.
This module uses browserify to create a browser compatible module. The default
grunt workflow for this project will generate both a full and minified browser
script in a build directory which can be included as a <script> tag:
<script src="deferred.browser.min.js"></script>
The package is exposed via the global name 'deferredjs'.
Running the npm test command will kick off the default grunt workflow. This
will lint using jslint, run the mocha/expect tests, generate a browser module,
and run the community specification tests.
