+ *
+ * 2) Links with libuv and uses the plugins at runtime
+ *
+ * 3) Uses advanced lws features like mounts to bind parts of the filesystem
+ * to the served URL space
+ *
+ * Another option is lwsws, this operates like test-server-v2,0.c but is
+ * configured using JSON, do you do not need to provide any code for the
+ * serving action at all, just implement your protocols in plugins.
