+ * A runtime to do bare-metal PHP without using superglobals.
+ *
+ * One option named "debug" is supported; it toggles displaying errors
+ * and defaults to the "APP_ENV" environment variable.
+ *
+ * The app-callable can declare arguments among either:
+ * - "array $context" to get a local array similar to $_SERVER;
+ * - "array $argv" to get the command line arguments when running on the CLI;
+ * - "array $request" to get a local array with keys "query", "body", "files" and
+ *   "session", which map to $_GET, $_POST, $FILES and &$_SESSION respectively.
+ *
+ * It should return a Closure():int|string|null or an instance of RunnerInterface.
+ *
+ * In debug mode, the runtime registers a strict error handler
+ * that throws exceptions when a PHP warning/notice is raised.
