+The Quagga architecture consists of a core daemon, @command{zebra}, which
+acts as an abstraction layer to the underlying Unix kernel and presents the
+Zserv API over a Unix or TCP stream to Quagga clients.  It is these Zserv
+clients which typically implement a routing protocol and communicate routing
+updates to the zebra daemon.")
