define Package/kea/description
  Kea is an open source DHCPv4/DHCPv6 server being developed by Internet
  Systems Consortium. Kea is a high-performance, extensible DHCP server
  engine that is designed to be easily modified and extended with hooks
  libraries. It provides DHCPv4 and DHCPv6 servers, a dynamic DNS update
  module, a portable DHCP library, libdhcp++, control agent that provides
  management REST interface, and a DHCP benchmarking tool, perfdhcp.
