-| Register The Composer Auto Loader
+| Include The Compiled Class File
 |--------------------------------------------------------------------------
 |
-| Composer provides a convenient, automatically generated class loader
-| for our application. We just need to utilize it! We'll require it
-| into the script here so that we do not have to worry about the
-| loading of any our classes "manually". Feels great to relax.
+| To dramatically increase your application's performance, you may use a
+| compiled class file which contains all of the classes commonly used
+| by a request. The Artisan "optimize" is used to create this file.
