+
+;;; Commentary:
+
+;; This file is only needed when using AMS-LaTeX 1.1 and LaTeX 2.09.
+;; In later versions of LaTeX and AMS-LaTeX this file is never used,
+;; because there is no longer a class or package name amstex.
+;;
+;; As far as AUCTeX is concerned, the old amstex style is fairly
+;; similar to the new amsmath package. So we will just run that hook
+;; here.
+;;
+;; amsmath.el should not be loaded, if an AMS-TeX (in contrast to
+;; AMS-LaTeX) file is opened.  The commands defined in amsmath.el
+;; mostly have no meaning in this case and errors about unknown
+;; variables or functions may occur due to latex.el possibly not being
+;; loaded.
+
+;;; Code:
+
+(TeX-add-style-hook
+ "amstex"
+ (function
+  (lambda ()
+    (unless (memq major-mode '(plain-tex-mode ams-tex-mode))
+      (TeX-run-style-hooks "amsmath")))))
+
+(defvar LaTeX-amstex-package-options '("noamsfonts" "psamsfonts" 
+				       "intlimits" "nointlimits"
+				       "sumlimits" "nosumlimits"
+				       "namelimits" "nonamelimits"
+				       "leqno" "reqno" "centertags"
+				       "tbtags" "fleqn" "righttag"
+				       "ctagsplt" "intlim" "nosumlim"
+				       "nonamelm")
+    "Package options for the amstex package.")
+
+;;; amstex.el ends here.
