dns Then
=======


Thin wrapper arround Node's dns module that makes the async functions promise
aware. The wrapped methods return a promise the represents the value of the
async operation. Traditional callbacks still work, allowing for a transparent
drop-in for dns. Sync methods, classes and other helpers are not modified.

Example
-------

Traditional Async

``javascript
var dns = require('dns-then');
dns.lookup('cujojs.com', function (err, address) {
...
});
`

With Promises

`javascript
var dns = require('dns-then');
dns.lookup('cujojs.com').then(...);
``
