;;; Commentary:
|
|
|
|
;; This file adds support for `multibib.sty' v1.4 form 2008-12-10.
|
|
|
|
;; Note for RefTeX users: multibib package allows multiple macro calls
|
|
;; to load bibliography database files. RefTeX bundled with Emacs
|
|
;; 29.1 is adjusted to recognize this. For prior Emacs versions, the
|
|
;; following code in the preamble should suffice to "fool" AUCTeX and
|
|
;; RefTeX for multiple bibliography calls:
|
|
;;
|
|
;; \iffalse
|
|
;; \usepackage{biblatex}
|
|
;; \fi
|
|
