BB4Win

The original of the blackbox-work-alike shell replacements for Windows. Blackbox is a manager written for Posix systems using X-Windows (like Gnome or KDE, but small and fast). Saying it is Spartan is an understatement. It was written to be as little as was needed to work self-contained and self-sufficient, but leave customization as an option. Someone decided this type of environment was needed as a shell replacement for a PC running Windows, instead of the default (convoluted?) shell/manager/browser hodge-podge provided by the manufacturer. BB4Win is the first one of these shells.
