"cronolog" is a simple program that reads log messages from its input
and writes them to a set of output files, the names of which are
constructed using template and the current date and time.  The
template uses the same format specifiers as the Unix date command
(which are the same as the standard C strftime library function).

"cronolog" is intended to be used in conjunction with a Web server, such
as Apache to split the access log into daily or monthly logs. For
example the Apache configuration directives:

	TransferLog "|/www/sbin/cronolog /www/logs/%Y/%m/%d/access.log"
	ErrorLog    "|/www/sbin/cronolog /www/logs/%Y/%m/%d/errors.log"

would instruct Apache to pipe its access and error log messages into
separate copies of cronolog, which would create new log files each day
in a directory hierarchy structured by date, i.e. on 31 December 1996
messages would be written to

	/www/logs/1996/12/31/access.log
	/www/logs/1996/12/31/errors.log

after midnight the files

	/www/logs/1997/01/01/access.log
	/www/logs/1997/01/01/errors.log

would be used, with the directories 1997, 1997/01 and 1997/01/01 being
created if they did not already exist.
