The make utility automatically determines which pieces of a large program need to be recompiled, and issues commands to recompile them（make工具自动决定哪些源文件需要重新编译，然后执行相应的命令去重新编译那些源文件）. This manual describes GNU make, which was implemented by Richard Stallman and Roland McGrath. Development since Version 3.76 has been handled by Paul D. Smith.
GNU make conforms to（遵守） section 6.2 of IEEE Standard 1003.2-1992 (POSIX.2).
Our examples show C programs, since they are most common, but you can use make with any programming language whose compiler can be run with a shell command. Indeed, make is not limited to programs. You can use it to describe any task where some files must be updated automatically from others whenever the others change. （make的使用并不受限于程序，你可以使用它在一些需要自动更新文件的场合。）
