Framework for window manager implementation
The xcb-util module provides a number of libraries which sit on top of libxcb, the core X protocol library, and some of the extension libraries. These experimental libraries provide convenience functions and interfaces which make the raw X protocol more usable. Some of the libraries also provide client-side code which is not strictly part of the X protocol but which have traditionally been provided by Xlib.
WM module is a Framework for window manager implementation. It brings both client and window-manager helpers for ICCCM and EWMH.
