Luvit 介绍
Luvit - Lua + UV + Jit = NodeJS re-implemented in Lua
如上面标题所描述的，Luvit 相当于 luajit2 + libuv，编译成单个可执行文件，类似
Node.js ，可运行 .lua 文件。
示例代码（创建一个HTTP服务器）
-- Load the http library
local HTTP = require("lib/http")
-- Create a simple nodeJS style hello-world server
HTTP.create_server(function (req, res)
res:write_head(200, {
["Content-Type"] = "text/plain",
["Content-Length"] = "11"
})
res:write("Hello World")
res:finish()
end):listen(8080)
-- Give a friendly message
print("Server listening at http://localhost:8080/")
