I'm trying to get the result of the command "ls" in a list, for
example : 
        (define l (system->list "ls"))

I've tried 'system' but it doesn't work since it returns the exit code
of the command. Maybe, I will be able to do that using port, but maybe
there's already a library to do such things.
