 (mudar titulo, nome, descrição, etc) para fazer com que o Pocketcast reconheça
 o feed gerado como se fosse outro feed. Eles usam a metadata para decidir se um
 feed e novo, então como eu não mexia na metadata ele gerava um link para o feed

+original do jovem nerd. Para ativar essa funcionalidade use parametro
+`tag=true`, exemplo:
+
+```

+```
 
 Entao os usuarios do Pocketcast tem que ir ao https://pocketcasts.com/submit/
 para submeterem a sua URL. Observação, esse processo de submit deles e meio
 cagado, então se ele não oferecer o feed certo tente trocar as ordens dos
 parâmetro, se tiver `nerdcast,mamicas` troque para `mamicas,nercast`
