Logging based on date

Hi,

	I would like to ask was it possible for kannel to write the log file
based on date? Which mean every day/week a new log file is created for the
purpose of logging. The current logging will only log on the same log
file. Ie. Current log file name : smsbox.log --> become
2008-01-01-smsbox.log, 2008-01-02-smsbox.log.
