 /**
- * A generic ErrorHandler for the PHP engine.
+ * ErrorHandler.
  *
- * Provides five bit fields that control how errors are handled:
- * - thrownErrors: errors thrown as \ErrorException
- * - loggedErrors: logged errors, when not @-silenced
- * - scopedErrors: errors thrown or logged with their local context
- * - tracedErrors: errors logged with their stack trace
- * - screamedErrors: never @-silenced errors
- *
- * Each error level can be logged by a dedicated PSR-3 logger object.
- * Screaming only applies to logging.
- * Throwing takes precedence over logging.
- * Uncaught exceptions are logged as E_ERROR.
- * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
- * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
- * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
- * As errors have a performance cost, repeated errors are all logged, so that the developer
- * can see them and weight them as more important to fix than others of the same level.
