+  A magic autoload comment (often called an @dfn{autoload cookie})
+consists of @samp{;;;###autoload}, on a line by itself,
+just before the real definition of the function in its
 autoloadable source file.  The command @kbd{M-x update-file-autoloads}
 writes a corresponding @code{autoload} call into @file{loaddefs.el}.
 Building Emacs loads @file{loaddefs.el} and thus calls @code{autoload}.
