 |--------------------------------------------------------------------------
 | Elixir Asset Management
 |--------------------------------------------------------------------------
 |
 | Elixir provides a clean, fluent API for defining some basic Gulp tasks
 | for your Laravel application. By default, we are compiling the Less
 | file for our application, as well as publishing vendor resources.
 |
 | A note on Bootstrap: source files via bower copy to assets/sass/bootstrap
 | keep an updated manifest file sass/app.scss which calls the resources
 | from the assets/sass/bootstrap folder (not the bower one). Sprinkle
 | in custom scss files and variable over rides within any order of
 | the manifest.
