+==Fail to launch Tweak Tool - LD_LIBRARY_PATH set to /cs/local.lib==
+This failed because the script is python based and needs a module "gi"
+If a user has his/her environment variable LD_LIBRARY_PATH set to /cs/local/lib, it will fail. The work around is to unset the environment variable and run gnome-tweak-tool . An alternative is to add the "gi" module to our installed python in /cs/local/bin
