+What is Keepalived ?
+
+The main goal of the keepalived project is to add a strong & robust
+keepalive facility to the Linux Virtual Server project. This project
+is written in C with multilayer TCP/IP stack checks. Keepalived
+implements a framework based on three family checks: Layer3, Layer4
+& Layer5/7.
+
+This framework gives the daemon the ability of checking a LVS server
+pool states. When one of the server of the LVS server pool is down,
+keepalived informs the linux kernel via a setsockopt call to remove
+this server entrie from the LVS topology. In addition keepalived
+implements an independent VRRPv2 stack to handle director failover.
+So in short keepalived is a userspace daemon for LVS cluster nodes
+healthchecks and LVS directors failover.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|' on
+# the right side marks the last column you can put a character in.  You must make
+# exactly 11 lines for the formatting to be correct.  It's also customary to
+# leave one space after the ':'.
