The make utility automatically determines which pieces of a large program need to be recompiled, and issues commands to recompile them. This manual describes GNU make, which was implemented by Richard Stallman and Roland McGrath. This book is available as a free PDF from gnu.org.
The Make program is indispensable to maintainers of free software systems. The GNU Make manual, written by the program's original authors, is the definitive tutorial. It also includes an introductory chapter for novice users. The Make utility automates the process of compilation; it is especially useful when the source files of large programs change. It is a small program with a lot of power.

This book will show you:
