// Brunch automatically concatenates all files in your
// watched paths. Those paths can be configured at
// config.paths.watched in "brunch-config.js".
//
// However, those files will only be executed if
// explicitly imported. The only exception are files
// in vendor, which are never wrapped in imports and
// therefore are always executed.
// Import dependencies
//
// If you no longer want to use a dependency, remember
// to also remove its path from "config.paths.watched".

// Local files can be imported directly using relative
// paths "./socket" or full ones "web/static/js/socket".
