  * will ask the configured ACL interface if access is granted. Under the assumptions 1. and 2. this will be

  * If the configured map looks like
  *
- *    $config['map'] = array(
- *       'User' => 'User/username',
- *       'Role' => 'User/group_id',
- *    );

  *
  * then PhpAcl will lookup if we defined a role like User/jeff. If that role is not found, PhpAcl will try to
  * find a definition for Role/4. If the definition isn't found then a default role (Role/default) will be used to
  * check rules for the given ACO. The search can be expanded by defining aliases in the alias configuration.
  * E.g. if you want to use a more readable name than Role/4 in your definitions you can define an alias like
  *
- *    $config['alias'] = array(
- *       'Role/4' => 'Role/editor',
- *    );
+ * {{{
+ * $config['alias'] = array(
+ *    'Role/4' => 'Role/editor',
+ * );
+ * }}}
  *
  * In the roles configuration you can define roles on the lhs and inherited roles on the rhs:
  *
- *    $config['roles'] = array(
- *       'Role/admin' => null,
- *       'Role/accountant' => null,
- *       'Role/editor' => null,
- *       'Role/manager' => 'Role/editor, Role/accountant',
- *       'User/jeff' => 'Role/manager',
- *    );
+ * {{{
+ * $config['roles'] = array(
+ *    'Role/admin' => null,
+ *    'Role/accountant' => null,
+ *    'Role/editor' => null,
+ *    'Role/manager' => 'Role/editor, Role/accountant',
+ *    'User/jeff' => 'Role/manager',
+ * );
+ * }}}
  *
  * In this example manager inherits all rules from editor and accountant. Role/admin doesn't inherit from any role.
  * Lets define some rules:
  *
- *    $config['rules'] = array(
- *       'allow' => array(
- *       	'*' => 'Role/admin',
- *       	'controllers/users/(dashboard|profile)' => 'Role/default',
- *       	'controllers/invoices/*' => 'Role/accountant',
- *       	'controllers/articles/*' => 'Role/editor',
- *       	'controllers/users/*'  => 'Role/manager',
- *       	'controllers/invoices/delete'  => 'Role/manager',
- *       ),
- *       'deny' => array(
- *       	'controllers/invoices/delete' => 'Role/accountant, User/jeff',
- *       	'controllers/articles/(delete|publish)' => 'Role/editor',
- *       ),
- *    );
+ * {{{
+ * $config['rules'] = array(
+ *    'allow' => array(
+ *        '*' => 'Role/admin',
+ *        'controllers/users/(dashboard|profile)' => 'Role/default',
+ *        'controllers/invoices/*' => 'Role/accountant',
+ *        'controllers/articles/*' => 'Role/editor',
+ *        'controllers/users/*'  => 'Role/manager',
+ *        'controllers/invoices/delete'  => 'Role/manager',
+ *    ),
+ *    'deny' => array(
+ *        'controllers/invoices/delete' => 'Role/accountant, User/jeff',
+ *        'controllers/articles/(delete|publish)' => 'Role/editor',
+ *    ),

  * Ok, so as jeff inherits from Role/manager he's matched every rule that references User/jeff, Role/manager,
  * Role/editor, Role/accountant and Role/default. However, for jeff, rules for User/jeff are more specific than
