Hi there,

thanks for the work. However, I am not going to merge that into the core since the default fornats only serve as templates. I've deliberately left out the unknown log level, since I've never seen anyone using it (though it is supported for backwards compatibility.

If you want to get the result you are seeking, you can do the following:

logger = Yell.new 'development.log', :format => "%d [%7L] %p : %m"

Am am currently working on better (global) configuration, although you can already set-up yell from a YAML file.
