;;; Commentary:
|
|
|
|
;; This file adds support for `ntheorem.sty' (v1.33) from 2011/08/15.
|
|
;; `ntheorem.sty' is and part of TeXLive.
|
|
|
|
;; This style interacts with AUCTeX and RefTeX mechanisms for
|
|
;; inserting labels into new defined environments with "\newtheoreom".
|
|
;; AUCTeX users need to add the new environment to `LaTeX-label-alist'
|
|
;; via customize or in init-file like this:
|
|
;;
|
|
;; (add-to-list 'LaTeX-label-alist '("lemma" . "lem:"))
|
|
;;
|
|
;; RefTeX users have to add the value to both `LaTeX-label-alist' and
|
|
;; `reftex-label-alist' like this:
|
|
;;
|
|
;; (add-to-list 'LaTeX-label-alist '("lemma" . "lem:"))
|
|
;; (add-to-list 'reftex-label-alist
|
|
;; '("lemma" ?m "lem:" "~ref{%s}"
