;;; Commentary:
;; This file adds support for `theorem.sty' (v2.2c) from 2014/10/28.
;; `theorem.sty' is a standard LaTeX package and part of TeXLive.
;; The style provides the function `LaTeX-theorem-env-label' which
;; enables new defined environments with "\newtheoreom" to interact
;; with AUCTeX and RefTeX mechanisms for inserting labels. Check
;; docstring of `LaTeX-theorem-env-label' for instructions.
;;; Code:
(require 'crm)
(require 'tex)
(require 'latex)
;; Silence the compiler:
