 *     production
 *
 * NOTE: If you change these, also change the error_reporting() code below

 * routing in a specific front controller that shares a common CI installation.

 * IMPORTANT: If you set the routing here, NO OTHER controller will be

 * specific controller. Leave the function name blank if you need
 * to call functions dynamically via the URI.

 *  CUSTOM CONFIG VALUES

 *
 * The $assign_to_config array below will be passed dynamically to the

 * This can be handy as it permits you to share one application between
