-;;; Commentary:
-;;
-;; gmpasm-mode is an editing mode for m4 processed assembler code and m4
-;; macro files in GMP. It's similar to m4-mode, but has a number of
-;; settings better suited to GMP.
-;;
-;;
-;; Install
-;; -------
-;;
-;; To make M-x gmpasm-mode available, put gmpasm-mode.el somewhere in the
-;; load-path and the following in .emacs
-;;
-;; (autoload 'gmpasm-mode "gmpasm-mode" nil t)
-;;
-;; To use gmpasm-mode automatically on all .asm and .m4 files, put the
-;; following in .emacs
-;;
-;; (add-to-list 'auto-mode-alist '("\\.asm\\'" . gmpasm-mode))
-;; (add-to-list 'auto-mode-alist '("\\.m4\\'" . gmpasm-mode))
-;;
-;; To have gmpasm-mode only on gmp files, try instead something like the
-;; following, which uses it only in a directory starting with "gmp", or a
-;; sub-directory of such.
-;;
-;; (add-to-list 'auto-mode-alist
-;; '("/gmp.*/.*\\.\\(asm\\|m4\\)\\'" . gmpasm-mode))
-;;
-;; Byte compiling will slightly speed up loading. If you want a docstring
-;; in the autoload you can use M-x update-file-autoloads if you set it up
-;; right.
-;;
-;;
-;; Emacsen
-;; -------
-;;
-;; FSF Emacs 20.x - gmpasm-mode is designed for this.
-;; XEmacs 20.x - seems to work.
-;;
-;; FSF Emacs 19.x - should work if replacements for some 20.x-isms are
-;; available. comment-region with "C" won't really do the right thing
-;; though.
