Debian GNU/Linux is the largest Linux distribution - developed entirely by unpaid volunteers on the Internet - over 400 programmers and developers.

A Linux distribution that includes its own configuration tool as well as the mainstream applications found in the other major distributions. Includes KDE and Netscape as well as the Apache web server.

Built from Debian GNU/Linux this distribution provides all of the benefits of a Debian system. By packaging the best and most commonly used applications into a simple to install CD, you can have a complete desktop up and running in a short time. All the power of Debian is now available to users with little or no Linux experience. The Libranet distribution is backed by solid support and online documentation. Software upgrades are available free to download, or on a CD. Debian's unique package manager takes care of software updates automatically.
