+Intuito: ajudar no controle do desenvolvimento para
+         que o codigo nao estufe de lixo e que se mantenha seguro.

+-------------------------------------------------------------
+
+  - Coloque as novas variaveis criadas na lista de variaveis
+  - Coloque as novas funcoes criadas na lista de funcoes
+  - Coloque os novos arrays na variavei USED_ARRAYS
+  - Se estiver usando um comando unix, verifique se o mesmo jah estah listado
+    na lista de programas, caso contrario adicione-o
+
+Uso de variaveis
+----------------
+
+  - Variaves globais: uppercase
