+@item autoload object
+@cindex autoload object

+the autoload object is called, it will make Emacs load the file
+containing the definition of the real function, and then call the real
+function instead.

This function ignores any arguments and returns @code{nil}.
@end defun
+ Emacs Lisp functions can also be user-visible @dfn{commands}. A
+command is a function that has an @dfn{interactive} specification.
+You may want to call these functions as if they were called
+interactively. See @ref{Interactive Call} for details on how to do
+that.
