Pybtex is a BibTeX-compatible bibliography processor written in Python. Pybtex aims to be 100% compatible with BibTeX. It accepts the same command line options, fully supports BibTeX’s .bst styles and produces byte-identical output. Additionally: - Pybtex is Unicode-aware. - Pybtex supports bibliography formats other than BibTeX. - It is possible to write formatting styles in Python. - As a bonus, Pythonic styles can produce HTML, Markdown and other markup besides the usual LaTeX. Pybtex also includes a Python API for managing bibliographies from Python.
