logrotate 3.7.8-4ubuntu2.2 (amd64 binary) in ubuntu lucid

 The logrotate utility is designed to simplify the administration of
 log files on a system which generates a lot of log files. Logrotate
 allows for the automatic rotation compression, removal and mailing of
 log files. Logrotate can be set to handle a log file daily, weekly,
 monthly or when the log file gets to a certain size. Normally, logrotate
 runs as a daily cron job.
