+	  luvi extends LuaJIT with asynchronous I/O and several optional
+	  modules to run Lua applications and build self-contained binaries
+	  on systems that don't have a compiler.
+
+	  The luvi core can be extended with several Lua modules by adding its
+	  bundled Lua binding libraries. To get the Lua module...
