How it works...

In this recipe, we have provided some custom code needed for a very simple Gruntfile.js file to work in step 6 . What follows is the breakdown of what the code does.

On line 1, we use the strict mode. On line 3, we call the grunt module. Line 4 instructs grunt to read our package.json file. Lines 7-13 specify the copy task. Line 17 is the entry point that registers the 'copy' task as the default task.
