[支持编译器的版本]
使用 TDM-GCC 4.8.1 及以上版本的集成开发环境都可以支持。例如：
● Code::Blocks 13.12 及以上版本
● DevCpp 5.8.0 及以上版本
同时额外支持：
● DevCpp 5.4.0 GCC MinGW 4.7.2
● C-Free 5.0（内置 GCC MinGW 3.4.5）
[文件列表]
include 头文件
lib32 32 位库文件
lib64 64 位库文件
lib-for-devcpp_5.4.0 仅适用于 DevCpp 5.4.0 MinGW 4.7.2 和 C-Free 5.0
[安装方法]
将 include 文件夹下的头文件和 lib32/lib64 文件夹下的库文件，分别拷贝到 MinGW 的头文件和库文件文件夹中，链接选项增加：-leasyx，然后编译即可。
