I was using [cpy](https://www.npmjs.com/package/cpy) with a globbing pattern to find and copy all the files in `src/main/css` and place them in `./dist`. 

However now I also have sub directories below `src/main/css` (For example `src/main/css/margins/index.css`) and [cpy](https://www.npmjs.com/package/cpy) does not include these when copying the files. 

Is there an API in Node (fs or path?) that handles this case, or anyone know of a handy package?
