;;; Commentary:
;;;
;;; This module provides a helper procedure to output bibliography entries
;;; according to a given template, as well as ready-to-use templates. A
;;; template only contains part of the style information for a bibliography
;;; entry. Specific style information can be added by modifying the markup
;;; writers for `&bib-entry-author', `&bib-entry-title', etc. (see `(skribilo
;;; package base)' for details).
;;;
;;; Code:
;;;
;;; Outputting a bibliography entry template for a specific entry.
