Finding the file version of a win32 dll in Ruby

Is there a way to determine the file version attribute in win32 using Ruby?
I would like to report and compare file versions between 2 different windows
computers using Ruby. I am mainly concerned with dll, ocx and exe file
types.

Thanks for any help.

I use filever.exe (download from [1] and/or win xp sp2 cd) and this:

module Win
  class Version
    class << self
      # returns version as array i.e. [1, 2, 12312, 5] or
      # empty array
      def get_version_array(path)
        (get_version(path) || '').split('.').collect {|i| i.to_i}
      end

      # return version as string ('1.2.12312.5') or nil
      def get_version(path)
        ver = short(path)
        ver.empty? ? nil : ver[14..30].strip
      end

      def short(path)
        `filever /B /A "#{Path.to_win(path)}" 2>&1`
      end

      def full(path)
        `filever.exe /V "#{Path.to_win(path)}" 2>&1`
      end
    end
  end
end
