    Add the following to your ~/.bash_profile:
      if [ -f $(brew --prefix)/share/bash-completion/bash_completion ]; then
        . $(brew --prefix)/share/bash-completion/bash_completion
      fi

      Homebrew's own bash completion script has been linked into
        #{compdir}
      bash-completion will automatically source it when you invoke `brew`.

      Any completion scripts in #{Formula["bash-completion"].compdir}
      will continue to be sourced as well.
