Is it possible to include external file with webpack (outside the context) and make the file included in built output bundle.js?

consider this setup where sub-app is context for webpack:

• /sub-app/entry.js


• /bower-components/zepto/zepto.js

And webpack config with broccoli:

var webpackify = require('broccoli-webpack');

var path = require('path');

var webpack = require(webpack);



var bundler = webpackify(path.resolve('sub-app'), {

    entry: './entry',

    output: {filename: './bundle.js'},

    devtool: 'eval',



    module: {

      loaders: [

        {test: /.js$/, loader: 'babel-loader'},

        {test: /.hbs$/, loader: handlebars-loader}

      ]

    },

    plugins: [

      new webpack.optimize.DedupePlugin(),

      new webpack.optimize.UglifyJsPlugin()

    ]

});

I would like to include zepto.js in output bundle.js. But I need to preserve bower_components outside the sub-app.
