+# Motivo 1: para aplicações de usuário, é mais fácil calcular a partir do horário

+# Vamos definir o idioma padrão (e também outras configurações de localização)
+# para o português
+# Motivo 1: aguia-pescadora é voltada para pessoas falantes de português
+# Motivo 2: mesmo que pessoas administradoras do servidor saibam inglês as
+#           pessoas que criam aplicações (principalmente as que usam ferramentas
+#           com menos abstrações, como as por shell) poderiam ter mais
