;;; Commentary:
;;; Description:
;;;
;;;	This file defines the hm--html-mode, a mode for editing html
;;;	files. It is the main file of the package hm--html-menus.
;;;	Previous releases had used the file html-mode.el from Marc
;;;	Andreessen. In that times the mode was called html-mode. I've
;;;	changed the name of the mode to distinquish it from other
;;;	html modes. But feel free to set a 
;;;		(defalias 'hm--html-mode 'html-mode)
;;;	to get back the old name of the mode.
;;;
;;;	In the earlier releases of the package the main file was
;;;	hm--html-menu.el. This has been changed to hm--html-mode.el.
;;; 
;;; Installation: 
;;;   
;;;	Put this file and all the other files of the package
;;;	in one of your load path directories and the
;;;	following lines in your .emacs:
;;;	
;;;	(autoload 'hm--html-mode "hm--html-mode" "HTML major mode." t)
;;;
;;;	(or (assoc "\\.html$" auto-mode-alist)
;;;         (setq auto-mode-alist (cons '("\\.html$" . hm--html-mode) 
;;;				        auto-mode-alist)))
;;;	If there is already another html-mode (like psgml in the XEmacs
;;;	19.14, then you must put the following instead of the last form
;;;	in your .emacs:
;;;	(setq auto-mode-alist (cons '("\\.html$" . hm--html-mode) 
;;;				        auto-mode-alist))
;;;
;;;	Look at the file hm--html-configuration for further installation
;;;     points.
