Issue SCRUM#119: Implements old standard in this new script

README.md

+Essa é a versão modular do script de geração de isos do le6.
+
+Este script gera uma iso de acordo com os scripts habilitados na pasta ´scripts-enabled´
+para cada distribuição, este modelo está configurado para funcionar com a distrubuição
+le6/testing, para criar uma nova distribuição basta criar uma pasta com o nome da nova
+distribuição nos diretórios, pkg-list, que contém as listas de pacotes que devem ser
+instalados e removidos, em scripts-enabled, e linkar os scripts que devem ser executados
+para a geração da iso. iso, onde será criada a imagem. log, onde será criado o arquivo
+de log, e em conf, e nessa pasta criar um arquivo de configuração para a geração da iso.
+
+Esta versão não mantem o diretório base "limpo", ou seja, a cada execução as modificações
+para a geração da iso se mantém.
