+rendering bibliographic reference citations into a variety of styles using a
+macro language called @dfn{Citation Style Language} (CSL).  This package also
+contains an executable @code{pandoc-citeproc}, which works as a pandoc filter,
+and also has a mode for converting bibliographic databases a YAML format
+suitable for inclusion in pandoc YAML metadata.")
