+### utils.watchDir() function
+
+Watches for changes to the given directory and calls the function provided
+when the directory changes. It works by calling watchFile/watchDir for each
+file/subdirectory.
+
+#### Parameters
+ 
+ * Dir - the file to watch (can be a file or directory)
+ * Callback - The callback to invoke when the directory has changed. 
+              The callback takes the changed file as a parameter. 
+              For each change inside the directory the callback will also 
+              be called.
+
+#### Example
+
+```javascript
+var utils = require('utils');
+utils.watchDir( 'players/_ial', function( dir ) { 
+   console.log( dir + ' has changed');
+});
+```
