Autoconf 是自动生成软件源代码配置脚本的工具，由此可以通过这个配置脚本，根据具体的应用场合，来配置软件源代码进行编译。-Autoconf is a tool for producing shell scr ipts that automatically configure software source

code packages to adapt to many kinds of unix-like systems. The configuration scr ipts

produced by Autoconf are independent of Autoconf when they are run, so their users do

not need to have Autoconf.
