Et il y a des outils/scripts supplémentaires en place pour gérer les traductions dans `./scripts/docs.py`.

!!! tip
    Vous n'avez pas besoin de voir le code dans `./scripts/docs.py`, vous l'utilisez simplement dans la ligne de commande.

E a maior parte do tempo de execução é tomada por trabalho (ao invés de ficar esperando), e o trabalho em um computador é feito pela <abbr title="Unidade de Processamento Central">CPU</abbr>, que podem gerar problemas que são chamados de "limite de CPU".

Exemplos comuns de limite de CPU são coisas que exigem processamento matemático complexo.

Por exemplo:

* **Processamento de áudio** ou **imagem**
