Ok, this seems really ellegant and I've tested that I can 
call "Logger.debug..." in any submodule/subclass into the program :)

Just a question: Logger must use an instance of a class (real class Logger), 
so to store it I think the best option is using a @@class_variable into 
Logger module, something like:

module MyProgram
   class MyLogger
  @@logger = Logger.new(xxxxx,xxxx)
   class << self
     def debug(text)
          @@logger.debug(txt)
    end
   end
   end
end


Is it ok?
Thanks a lot.
