import config

pp = pprint.PrettyPrinter(indent=4)
logging.basicConfig(filename=config.ROOT_PATH+"/rtt.log", level=logging.DEBUG)

# Add debugging print statements like this

logging.debug("reordering following sequence at depth " + str(depth))
logging.debug(pp.pformat(sequence))

# Run these commands to initialize logfile:
touch rtt.log
chmod 777 rtt.log
