;; This library registers the `bibtex' citation processor, which
|
|
|
|
|
|
;; provides the "export" capability for citations. It doesn't require
|
|
|
|
|
|
;; any LaTeX package.
|
|
|
|
|
|
;;
|
|
|
|
|
|
;; It supports the following citation styles:
|
|
|
|
|
|
;;
|
|
|
|
|
|
;; - nocite (n),
|
|
|
|
|
|
;; - default.
|
|
|
|
|
|
;;
|
|
|
|
|
|
;; Only suffixes are supported. Prefixes are ignored.
|
|
|
|
|
|
;;
|
|
|
|
|
|
;; Bibliography should consist of ".bib" files only.
