Subject: How distinguish between a file and a directory?

A newbie question. The code

    Dir.foreach(Dir.getwd) do |f|
      if ((f != '.') && (f != '..'))
        puts f
      end
    end

lists the files and directories in the current working directory but 
does not identify which is a file and which is a directory. How can I 
add that information to the listing? Thanks.
