+`/usr/local/lib/xemacs-VERSION/CONFIGURATION-NAME/modules' holds the Emacs
+ dynamically loadable modules. These are special programs
+ typically written in C that can be loaded in much the same
+ way that Lisp packages are. Not all systems support
+ dynamic modules, so do not be alarmed if this directory
+ does not exist or is empty.
+
+ XEmacs searches for modules in this directory, or any
+ sub-directory of it, and then in
+ `/usr/local/lib/xemacs/site-modules/*'.
