Constants

Fuel has four constants in the global namespace to direct you to important directories. Fuel uses them internally to locate classes and other files. These constants are set in public/index.php.

Note: When you move any of fuel's prime folders (app, core, public, packages) be sure to update you index.php to direct fuel to the right paths.
