;;; Commentary:
;; If a footnote is of the general form "AUTHOR, TITLE, PAGES", this
;; module offers a function to more intelligently markup such
;; citations. For LaTeX, it italicizes the TITLE and inserts correct
;; spacing and endashes in PAGES. For HTML, it is able to convert the
;; TITLE or PAGES into a link, given knowledge of where to find known
;; texts by certain authors.
;;
;; To use this module -- since it only rewrites markup, and is not
;; particular to any style -- modify `muse-before-publish-hook':
;;
;; (require 'muse-publish)
;; (require 'muse-cite)
;; (add-hook 'muse-before-publish-hook 'muse-cite-munge-footnotes)
