Pybtex is a BibTeX-compatible bibliography processor written in Python which
can produce formatted bibliographies in different, customizable formats. It
supports both native BibTeX style files and styles written in Python and
accepts BibTeX, BibTeXML, and a custom YAML-based bibligraphy input format and
can output LaTeX, HTML, and plain text.

Furthermore, Pybtex provides an interface for Python applications which need to
process the above formats.
