this package is created for a discussion at webpack/webpack#3128 about momentJS it's locale files being bundled in webpack.
npm run dev starts the dev server at localhost:8000, you'll see the dutch date.
Running npm run build and opening the index.html will give you the english date, although we've set locale to nl.
If you unquote // import 'moment/locale/nl'; and run build again, the dutch locale will have been included.
If you ask me, Webpack 2 treeshaking is dropping all the unused code, including all locale files.
