+Originally, it had been modified to add the xdg-settings command for getting
+and, in some cases, setting various GNU/Linux desktop environment settings like
+the default web browser and proxy configuration.
 
+This change has since been incorporated upstream.

+We now have this copy only to allow us to ship our own copy of xdg-settings (and
+xdg-mime, because we need a newer version than some distributions include). When
+these are standard, we can delete our copy.
