## 简介
RT-Thread中的Lua修改自[eLua](http://www.eluaproject.net/)的Lua-5.1.4版本。
Lua依赖于Neblib库。
采用gcc工具链时，Lua依赖于newlib库，其它工具链暂时还不支持。
启动lua的RAM占用情况

- 优化的lua 5.01953125 KB

3.更多的配置项可以在luaconf.h中找到
## 开发相关
- 采用gcc工具链时，依赖于newlib，需在rtconfig.h中定义RT_USING_NEWLIB
- 开启编译器对C99的支持，如MDK中，在C/C++选项的Misc Controls输入框中添加--c99
- 开启内存优化时：需要在链接脚本中定义_stext和_etext，.ordata*放在两者之间。
- 需要在链接脚本中定义_stext和_etext，.ordata*放在两者之间。
用于判断数据是read-only和writable。MDK中如何实现？？
- 添加新的模块，参见larduinolib.c
- 添加新的模块，参见lexample.c
## 目录说明
- lua：从eLua获得Lua-5.1.4版本代码
- exlibs：external libraries，外部库代码，如Arduino库
- exlibs：external libraries，外部库代码，如example库
- applications：Lua应用代码，如finsh中lua()
- test：测试代码
