[NTG-context] bib translation

Hello out there, in a bibliography created by Tacos' module I have something like this: Knuth, D. E. and Plass, M. F. (1999). Breaking paragraphs into lines. In Digital Typography, pages 67–155. CSLI Publications. Ursrpünglich publiziert in Software – Practice and Experience 11 (1981), 1119–1184. But now I'd like to have 'und' instead of 'and', 'Seiten' instead of 'pages' etc. What is the suggested way to do this? Patrick -- ConTeXt wiki and more: http://contextgarden.net
