+process (Net::Server::INET), a single connection server (Net::Server or
+Net::Server::Single), a forking server (Net::Server::Fork), a preforking
+server which maintains a constant number of preforked
+children (Net::Server::PreForkSimple), or as a managed preforking server which
+maintains the number of children based on server load (Net::Server::PreFork).
+In all but the inetd type, the server provides the ability to connect to one
+or to multiple server ports.")
