title: Using Angular-CLI build to copy a file / directory
body: <p>Is there a way to make angular-cli's <code>ng buil --prod</code> command to also copy a file/directory to the dist folder?</p>
  
  <p>My project includes a "server" folder, and a "config.js" file at root, and I need them to be copied to "dist" such that when building, I don't need to remember to copy those directories</p>
