+      Copas is a dispatcher based on coroutines that can be used by
+      TCP/IP servers. It uses LuaSocket as the interface with the
+      TCP/IP stack. A server registered with Copas should provide a
+      handler for requests and use Copas socket functions to send
+      the response. Copas loops through requests and invokes the
+      corresponding handlers. For a full implementation of a Copas
+      HTTP server you can refer to Xavante as an example.
