-/**
- * Authentication module for RSS-Bridge.
- *
- * This class implements an authentication module for RSS-Bridge, utilizing the
- * HTTP authentication capabilities of PHP.
- *
- * _Notice_: Authentication via HTTP does not prevent users from accessing files
- * on your server. If your server supports `.htaccess`, you should globally restrict
- * access to files instead.
- *
- * @link https://php.net/manual/en/features.http-auth.php HTTP authentication with PHP
- * @link https://httpd.apache.org/docs/2.4/howto/htaccess.html Apache HTTP Server
- * Tutorial: .htaccess files
- *
- * @todo Configuration parameters should be stored internally instead of accessing
- * the configuration class directly.
- * @todo Add functions to detect if a user is authenticated or not. This can be
- * utilized for limiting access to authorized users only.
