;;; Commentary:

;; 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.

;;; Code:
(require 'oc)

(declare-function org-element-property "org-element" (property element))

(declare-function org-export-data "org-export" (data info))

\f
