     "Rsyslog offers high-performance, great security features and a modular
design.  While it started as a regular syslogd, rsyslog has evolved into a
kind of swiss army knife of logging, being able to accept inputs from a wide
variety of sources, transform them, and output the results to diverse
destinations.")
