Comece pelo tratamento de :Dbg em commands.py e pelo ponto de entrada start_py em new_debugger.py; em seguida, compare o patch fornecido com os arquivos atuais. Verifique se a invocação de exemplo executa o script Python atual com os argumentos solicitados e se o comportamento existente do depurador permanece intacto.
