;;; Commentary:
;;
;; This is an utility to handle BibTeX export to both LaTeX and html
;; exports. It uses the bibtex2html software from
;; http://www.lri.fr/~filliatr/bibtex2html/
;;
;; The usage is as follows:
;; #+BIBLIOGRAPHY: bibfilebasename stylename
;; e.g. given foo.bib and using style plain:
;; #+BIBLIOGRAPHY: foo plain
;; For LaTeX export this simply inserts the lines
;; \bibliographystyle{plain}
;; \bibliography{foo}
;; into the tex-file when exporting.
;; For Html export it:
;; 1) converts all \cite{foo} to links to the bibliography
;; 2) creates a foo.html and foo_bib.html
;; 3) includes the contents of foo.html in the exported html file
