+%   15-feb-92   (MW)    Updated for use with `bibgerman.sty': things like "and"
+%                       change with the language. Switch the language using the
+%                       language field: 
+%                          language = "german" | "USenglish" | "english"
+%                       Then a `\selectlanguage{...}' command will be pushed just
+%                       before the `\bibitem...' command for the entry in work.
+%   2003/03/31 Harald Harders   Fixed bug in detection of "and others"
+%   2003/04/29 Harald Harders   Fixed bug format of names. For multiple
+%                               names, some of them were not typeset in
+%                               small caps.
