		### `.delay()` for future promises

		If you need a little bit of delay (such as retrying a method call to a service that is "eventually consistent") before doing something else, ``Q.delay()`` is your friend:

		```javascript
		getUrlContent(url1)
		.fail(function () {
		// Retry again after 200 milisseconds
		return Q.delay(200).then(function () {
		return getUrlContent(url1)
		})
		})
		```

		### `.fcall()` for Node.js callbacks

		``Q.fcall()`` can be used to convert node-style callbacks into promises:

		```javascript
		Q.fcall(fs.writeFile, '/tmp/myFile', 'content')
		.then(function () {
		console.log('File written successfully')
		})
		.fail(function (err) {
		console.log('Failed to write file', err)
		})
		```
