haskell-X11 (A Haskell binding to the X11 graphics library) The binding is a direct translation of the C binding; for documentation of these calls, refer to The Xlib Programming Manual, available online at http://tronche.com/gui/x/xlib/. This requires ghc from SlackBuilds.org. When uninstalling, run this command to unregister the package from the ghc package database: ghc-pkg unregister X11
