This is a Perl script I wrote a while back as a housekeeping tool for Linux systems. It looks in /var/log and in /etc/logrotate.d, comparing the existing log files to the ones mentioned in your logrotate configuration files, producing a helpful list of which files are not being rotated.

Found in old St. Paul's Church, Baltimore, dated 1692.

Reading many books at a time, one finds delicious coincidence.
