;;; 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
