    (description
     "Keepalived provides frameworks for both load balancing and high
availability.  The load balancing framework relies on the Linux Virtual
Server (IPVS) kernel module.  High availability is achieved by the Virtual
Redundancy Routing Protocol (VRRP).  Each Keepalived framework can be used
independently or together to provide resilient infrastructures.")
