Sua implantação deve ser feita por desenvolvedores experientes. **Isto não é um Plugin!** As opções que funcionam no modo de comando apenas servem para depuração em modo de desenvolvimento. A documentação mais importante está nos testes unitários. Se você não consegue ler os testes unitários, eu recomendo que não utilize esta biblioteca.
