Add profiling support to Melange. By assigning profile_main_as_logs or profile_main_as_html to main variable you can turn on profiling. profile_main_as_logs will log profile data to App Engine console logs, profile_main_as_html will show profile data as html at the bottom of the page. If you want to profile app on deployed app just set the profiling function and deploy it.
