;;; Commentary:
;; This file adds support for `xr.sty' v5.06 form 2020-05-10. RefTeX
;; has good support for referencing external \label's, so it should be
;; used.
;;; Code:
(require 'tex)
(require 'latex)
;; Silence the compiler:
(declare-function font-latex-add-keywords
"font-latex"
(keywords class))
