Openbox is a window manager for the X11 windowing system. It currently runs on a large list of platforms. It was originally based on Blackbox and currently remains very similar, even using Blackbox styles (with available extensions) for its themeing and is written entirely in C++ and maintains no dependencies on any libraries other than X11. This is the older 2.x version of openbox; for the current version look in the ``openbox'' package.
