 *  Error Reporting
 * --------------------------------------------------------------------
 *
 * PHP and database errors are normally displayed dynamically based
 * on the authorization level of each user accessing your site.
 * This variable allows the error reporting system to be overridden,
 * which can be useful for low level debugging during site development,
 * since errors happening before a user is authenticated will not normally
 * be shown.  Options:
 *
 * $debug = 0;  Default setting. Errors shown based on authorization level
 *
 * $debug = 1;  All errors shown regardless of authorization
 *
 * NOTE: Enabling this override can have security implications.
 * Enable it only if you have a good reason to.

 * --------------------------------------------------------------------
 *  CUSTOM CONFIG VALUES
 * --------------------------------------------------------------------
 *
 * The $assign_to_config array below will be passed dynamically to the
 * config class. This allows you to set custom config items or override
 * any default config values found in the config.php file.  This can
 * be handy as it permits you to share one application between more then
 * one front controller file, with each file containing different
 * config values.
 *
 * Un-comment the $assign_to_config array below to use this feature
 *
 * NOTE: This feature can be used to run multiple EE "sites" using
 * the old style method.  Instead of individual variables you'll
 * set array indexes corresponding to them.
