+   (description
+    "Unclutter is a program which runs permanently in the background of an
+X11 session.  It checks on the X11 pointer (cursor) position every few
+seconds, and when it finds it has not moved (and no buttons are pressed
+on the mouse, and the cursor is not in the root window) it creates a
+small sub-window as a child of the window the cursor is in.  The new
+window installs a cursor of size 1x1 but a mask of all 0, i.e. an
+invisible cursor.  This allows you to see all the text in an xterm or
+xedit, for example.  The human factors crowd would agree it should make
+things less distracting.")
