The goal of the OpenDarwin.org project, founded in April 2002 by Apple Computer and Internet Systems Consortium, is to create an independent branch of the Darwin operating system that increases collaboration between Apple developers and the open source community. Apple benefits from the project because improvements to OpenDarwin may be incorporated into Darwin releases; and the open source community benefits since it is given complete control over its own operating system, which can then be used in free distributions like GNU-Darwin.
The OpenDarwin developers use a version control system called CVS to manage changes to the OpenDarwin source code. Though many of the OpenDarwin developers are Apple employees, the OpenDarwin project is fully independent of Apple. The OpenDarwin developers have complete control over their code though they generally try to stay compatible with Apple's software.
Quality control
Like most modern operating systems, OpenDarwin employs a built-in kernel debugger to help the developers find kernel bugs.
