=========
The evaluation in SimulEval implemented as the Evaluator shown below.
It runs on sentence level, and will score the translation on quality and latency.
The user can use :code:`--quality-metrics` and :code:`--latency-metrics` to choose the metrics.
The final results along with the logs will be saved at :code:`--output` if given.

Customized Scorers
------------------
To add customized scorers, the user can use :code:`@register_latency_scorer` or :code:`@register_quality_scorer` to decorate a scorer class.
and use :code:`--quality-metrics` and :code:`--latency-metrics` to call the scorer. For example:
.. literalinclude:: ../../examples/quick_start/agent_with_new_metrics.py
:lines: 6-
.. code-block:: bash
> simuleval --source source.txt --target target.txt --agent agent_with_new_metrics.py --latency-metrics RTF
