33) How do I use BibTeX with plain TeX?

    The file btxmac.tex contains TeX macros and documentation for using
    BibTeX with plain TeX, either directly or with Karl Berry's Eplain
    package. It is available via anonymous ftp from labrea.stanford.edu
    (36.8.0.47) in tex/bibtex (see question 32 for more information about
    BibTeX).
