# 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.
