  This module will run bibtex blocks such as the following through
  bibtex2html.

  {{{#!bibtex
  @Book{            aho.74,
    author        = {Alfred V. Aho and John E. Hopcroft and Jeffrey D. Ullman},
    title         = {The Design and Analysis of Computer Algorithms},
    publisher     = {Addison-Wesley},
    year          = {1974},
    series        = {Addison-Wesley Series in Computer Science and Information
                    Processing}
  }
  }}}

  Several bibtex entries can be listed into the same block (and they can
  \cite each other).  The 'comment' element can be used to display a comment
  below each entry.

  If your wiki contains a page named HlinsDatabase, then hlins will be
  run on the result of bibtex2html, using the contents of HlinsDatabase
  as input (make sure you write this page with the correct syntax).

  bibtex2html: http://www.lri.fr/~filliatr/bibtex2html/
  hlins:       http://www.lsv.ens-cachan.fr/~treinen/hlins/
