SUMMARY = "Alternative system logger daemon"
DESCRIPTION = "syslog-ng, as the name shows, is a syslogd replacement, \
but with new functionality for the new generation. The original syslogd \
allows messages only to be sorted based on priority/facility pairs; \
syslog-ng adds the possibility to filter based on message contents using \
regular expressions. The new configuration scheme is intuitive and powerful. \
Forwarding logs over TCP and remembering all forwarding hops makes it \
ideal for firewalled environments. \
