+
+It was primarily designed for clipmenu, to avoid polling for new selections.
+
+@command{clipnotify} doesn't try to print anything about the contents of the
+selection, it just exits when it changes.  This is intentional -- X11's
+selection API is verging on the insane, and there are plenty of others who
+have already lost their sanity to bring us xclip/xsel/etc.  Use one of those
