[NTG-context] i18n in BibTeX

So, I've stumbled across a problem: if you have only two authors in a BibTeX entry, cont-au.bst sets "AuthorA and AuthorB" which is -- IMHO -- unaccaptable for a german document. I had to manually edit cont-au.bst and change a line in FUNCTION {format.lab.names} { 's := s #1 "{vv~}{ll}" format.name$ s num.names$ duplicate$ #2 > { pop$ " et~al." * } { #2 < 'skip$ { s #2 "{ff }{vv }{ll}{ jj}" format.name$ "others" = { " et~al." * } { " and " * s #2 "{vv~}{ll}" format.name$ * } if$ } if$ } if$ "{" swap$ * "}," * } from "and" to "und". Is there a cleaner way? If I typeset an english document now, I'll get an "und"... bye, Adam.
