GNU-Darwin aims to be the most free Darwin-based Unix distribution. Our mission is two-fold: focus on new projects that leverage the unique capabilities of Darwin/Mach, and help Apple users to enjoy the benefits of free software.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
OSX.1 users can now install the GNU-Darwin base distribution automatically with
one command. Darwin-only users will have to take a few extra steps to fetch
wget or curl. The beta sources are the first addition to the new BSD-style
source tree. The project's goal is to eventually mirror Apple's Darwin source
code in BSD src tree format. This release also features a new Fortran
distribution for Darwin and OSX.1 users.
