libxcb-keysyms1-dev - 0.4.0-1+b2 main

This package contains the header and library files needed to build software
using libxcb-keysyms, providing standard X key constants and conversion to/from
keycodes.
.
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.
