// applications served in subdirectories (e.g. example.com/foo/admin) we use a
// PathPackage to generate the right URLs for assets.
// This means that asset paths in 'manifest.json' should not contain any path:
//   'app.css' => 'app.1e1ba55d.css'
//
// Sadly, even is setPublicPath() in our webpack.config.js is empty, the generated
// 'manifest.json' adds leading slashes in all paths, which breaks PathPackage:
//   'app.css' => '/app.1e1ba55d.css'
//
// This function removes that leading slash from all asset paths.
