X11 authorisation library (development headers)
 This package provides the main interface to the X11 authorisation handling,
 which controls authorisation for X connections, both client-side and
 server-side.
 .
 This package contains the development headers for the library found in libxau6.
 Non-developers likely have little use for this package.
