Darwinbuild is a set of tools that facilitate building the sources released by Apple.
The Darwin Build Scripts are a collection of tools that assist compilation of the many projects contained in Darwin, the open source base of Apple's Mac OS X operating system. Apple publishes the sources of these projects in an archive format (.tar.gz). An archive is published for each project version on Apple's site. These tools will provide the proper build environment as well as help to resolve any necessary dependencies prior to building.
