;;; 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
