# Run this file to install libev and lua; if you already have lua and libev in your environment, you can ignore this file and try to compile directly using makefile.
# 运行这个文件可以安装libev与lua; 如果您的环境中已经有了lua/libeio/libev后可以忽略此文件并且直接使用makefile尝试编译.

# This file must be executed in the current folder directory, otherwise the installation will be wrong. Beginners need to keep in mind.
# 必须在当前文件夹目录执行此文件, 否则安装将会出错. 初学者需要谨记.

# Running this script in some embedded environments may lack the scripting tools that should be present (eg ls/printf/grep, etc.), you should find a way to install this command.
# 在一些嵌入式环境下运行此脚本可能会缺少本应存在的脚本工具(如: ls/printf/grep等等), 您应该想办法安装此命令.

# Before executing this build file, you need to make sure that these software environments are installed: gcc/clang autoconf automake make libtool git readline-devel openssl-devel.
# 执行这个编译文件之前需要确保安装了这些软件环境: gcc/clang autoconf automake make libtool git readline-devel openssl-devel. 如果未安装或者缺少安装, 请仔细检查并且自行尝试安装依赖环境.
