+;;; 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 optional-options
+;; e.g. given foo.bib and using style plain:
+;; #+BIBLIOGRAPHY: foo plain option:-d
+;;
+;; Optional options are of the form:
+;;
+;; option:-foobar pass '-foobar' to bibtex2html
+;; e.g.
+;; option:-d sort by date.
+;; option:-a sort as BibTeX (usually by author) *default*
+;; option:-u unsorted i.e. same order as in .bib file
+;; option:-r reverse the sort.
+;; see the bibtex2html man page for more. Multiple options can be combined like:
+;; option:-d option:-r
+;;
+;; Limiting to only the entries cited in the document:
+;; limit:t
+
+;; 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
