Bofhlog is a simple tool for "active" and "passive" monitoring of Unix
log files. "Active" means that you can see the changes in log files on
the screen as new log entries are entered by syslog. It is the same
functionality that "tail -f" offers, except that bofhlog can handle
logrotate. "Passive" means that you don't have to watch the logs all
the time; bofhlog can email or contact you by other means if something
"critical" is entered in the log files. "Critical" means that bofhlog
can be used both as a lightweight security auditing tool and as an
error diagnostic tool for a Unix system.
