            <literal>xstring</literal> imprime a matriz de strings
            <literal>str</literal> na localização <literal>x,y</literal> (ponto
            inferior esquerdo) na escala de gráficos corrente: cada linha da matriz
            significa uma linha de texto e os elementos das linhas são palavras
            separadas por espaços em branco. Se <literal>angle</literal> for dado,
            fornece a inclinação em graus para escrever os strings. Se
            <literal>box</literal> for 1 e <literal>angle</literal> for 0, uma caixa é
            desenhada ao redor dos strings.
