Lua Study Steps 1 run lua script file

Lua version 5.1

Lua是一个被设计成用于扩展C/C++编程的轻量级脚本语言.
1. http://www.lua.org/home.html download
   http://luaforge.net/frs/?group_id=110 binaries

Add include(source file) directory and library(*.dll and *.lib) directory in VC.
Look luavs.bat file for install, you can get luaXX.dll/XX.lib and lua.exe luac.exe.
Add the path to environment variables that you can run lua any path

2. first program
lua_open()返回一个指向Lua解释器的一个指针。
luaL_openlibs()用于装载Lua库，它提供了一些简单的函数，如：print。
通过调用luaL_dofile()执行脚本。它的作用是读取并解释脚本。
最后，通过lua_close()函数关闭Lua。

In Visual C++ you’ll need to follow these steps:
Create a new empty Win32 Console Application Project.
如果你直接使用C而不是C++，将文件名改为luatest.c，然后将extern "C"删除。
put *.lua to your *.cpp path or you need location absolute path for *.lua file
