# messages to various system log files.

### BEGIN INIT INFO
# Provides: $syslog
# Required-Start: $local_fs
# Required-Stop: $local_fs
# Short-Description: Next-generation syslog server
# 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.
### END INIT INFO
