 # libxcb-util
 
 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.
-
-These libraries are currently included, roughly ordered by maturity:
-* render-util: Convenience functions for the Render extension.
-* aux: Convenient access to connection setup and some core requests.
-* atom: Standard core X atom constants and atom caching.
-* property: Callback X property-change handling.
-* icccm: Both client and window-manager helpers for ICCCM.
-* keysyms: Standard X key constants and conversion to/from keycodes.
-* event: Callback X event handling.
-* image: Port of Xlib's XImage and XShmImage functions.
-* wm: Framework for window manager implementation.
