Instalacao do ambiente Ruby/Rails no RedHat 5.5
===============================================

Observacao: Na instalacao em outro S.O. (Linux) o processo eh muito parecido

Toda a instalacao foi feita como root. Se feita com algum usuario o RVM sera
instalado na pasta do usuario, e nao para todo o sistema. Atente-se a isso e
na duvida veja na documentacao do RVM.
