If you wanted to log stuff like you would in rails and sinatra, here would be a very clean way to do it.

            configure do
              Dir.mkdir('log') unless File.exists?('log')
            end
            
            configure :test do
              use Rack::CommonLogger, File.new('log/test.log', 'w')
            end
            
            configure :development do
              use Rack::CommonLogger, File.new('log/development.log', 'w')
            end
            
            configure :production do
              use Rack::CommonLogger, File.new('log/production.log', 'w')
            end
            

More updates to come once I get out of midterm hell next week.
