%description
    UCARP allows a couple of hosts to share common virtual IP
    addresses in order to provide automatic failover. It is a
    portable userland implementation of the secure and patent-
    free Common Address Redundancy Protocol (CARP, OpenBSD's
    alternative to the VRRP).

    Strong points of the CARP protocol are very low overhead,
    cryptographically signed messages, interoperability between
    different operating systems, and no need for any dedicated
    extra network link between redundant hosts.
