Description
In its current version, GNU-Darwin can be installed on top of a preexisting installation of Mac OS X, Darwin or OpenDarwin. The project plans to release a bootable installer that bundles the GNU-Darwin packages with OpenDarwin, thereby creating a one-step install, however after a number of years that has yet to appear.
The GNU-Darwin system is a port of the FreeBSD ports collection. Makefiles contain the instructions on the location of software packages and how to install them on Darwin. These Makefiles are arranged in a directory hierarchy. Users find the directory that corresponds to the software they want to install, and run a command within that directory that downloads the software, compiles and installs it. Alternatively, pre-compiled (binaries) packages are sometimes available that can be installed with the use of the pkg_add command.
GNU-Darwin also distribute some packages from the GNUstep project. The GNUstep project has been working since 1994 to create a free implementation of the OpenStep object-oriented development environment (which later became the Cocoa API on Mac OS X) on Unix.
All GNU-Darwin packages can be downloaded free of charge from the web. The project has also made its packages available for purchase on CD or DVDs, with proceeds going back to the project. Two examples include the 5 DVD set for PowerPC, which sells for $45 USD on the website, and the pre-installed hard drive for x86 or PowerPC, for $250 USD.

Famous quotes containing the word description:
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
