+;; Here are the definitions of most of the general-purpose functions and
+;; commands added by Prelude.  Some modules define additional module-specific
+;; functions and commands.

+;; Note that many of the original core Prelude commands were extracted to the

+;; functionality was extracted to the super-save package.
