libxcb-atom0-dev 0.2.1+git1-1 (sparc binary) in ubuntu jaunty

 This package contains the header and library files needed to build software
 using libxcb-atom, providing standard core X atom constants and atom caching.
 .
 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.
