+In order to use Motif (and the graphical debugger) with X servers from
+non-OSF vendors (like Sun) you may need to set the environment variable
+XKEYSYMDB to point to the file `lib/XKeySymDB'.  Otherwise, you will get many
+error messages every time a new connection is opened to the CMU CL motifd.
+This file is read by the X11R5 Xt in order to augment the keysym database with
+certain OSF vendor keysyms that Motif wants to use.
