Hello, I've started writing BibELTeX as an alternative to =ox-bibtex.el=.
https://github.com/ruediger/bibeltex Instead of calling =bibtex2html= it uses the functionality from =org- bibtex.el= to parse the BibTeX file and generates org-mode format for it. This has the advantage that it works with any output format (latex, html, odt, ascii, ...) and that it does not require external tools. BibELTeX is currently in a very early stage of development. The biggest design issue is the style format. Currently I use a =format-spec= like format which is not very good to work with (See =bibeltex-style-default=). Please feel free to criticise, comment, and open pull requests! Regards Rüdiger
