-;;; A "macro-only" reimplementation of define-derived-mode.

-;;;###autoload
-(defmacro define-derived-mode (child parent name &optional docstring &rest body)
-  "Create a new mode as a variant of an existing mode.
-
-The arguments to this command are as follow:
-
-CHILD:     the name of the command for the derived mode.
-PARENT:    the name of the command for the parent mode (e.g. `text-mode').
-NAME:      a string which will appear in the status line (e.g. \"Hypertext\")
-DOCSTRING: an optional documentation string--if you do not supply one,
-           the function will attempt to invent something useful.
-BODY:      forms to execute just before running the
-           hooks for the new mode.
-
-Here is how you could define LaTeX-Thesis mode as a variant of LaTeX mode:
-
-  (define-derived-mode LaTeX-thesis-mode LaTeX-mode \"LaTeX-Thesis\")
-
-You could then make new key bindings for `LaTeX-thesis-mode-map'
-without changing regular LaTeX mode.  In this example, BODY is empty,
-and DOCSTRING is generated by default.
-
-On a more complicated level, the following command uses `sgml-mode' as
-the parent, and then sets the variable `case-fold-search' to nil:
-
-  (define-derived-mode article-mode sgml-mode \"Article\"
-    \"Major mode for editing technical articles.\"
-    (setq case-fold-search nil))
-
-Note that if the documentation string had been left out, it would have
-been generated automatically, with a reference to the keymap."
