 %description
-With conntrack-tools you can setup a High Availability cluster and
-synchronize conntrack state between multiple firewalls.
-
-The conntrack-tools package contains two programs:
-- conntrack: the command line interface to interact with the connection
-             tracking system.
-- conntrackd: the connection tracking userspace daemon that can be used to
-              deploy highly available GNU/Linux firewalls and collect
-              statistics of the firewall use.
-
-conntrack is used to search, list, inspect and maintain the netfilter
-connection tracking subsystem of the Linux kernel.
-Using conntrack, you can dump a list of all (or a filtered selection  of)
-currently tracked connections, delete connections from the state table, 
-and even add new ones.
-In addition, you can also monitor connection tracking events, e.g. 
-show an event message (one line) per newly established connection.
+The conntrack-tools are a set of free software userspace tools for Linux 
+that allow system administrators interact with the Connection Tracking System, 
+which is the module that provides stateful packet inspection for iptables. 
+The conntrack-tools are the userspace daemon conntrackd and the command line 
+interface conntrack.
