[Koha] Changing the Marc-Flowers to another language

Hi all Some time ago I installed Koha on three times for different libraries. As it had been version 3.01 I had to choose the MARC-flavour and the language environment. I selected MARC21 in the english section. Due to the wonderful work Katrin Fischer has done there is now a german version of MARC21 (both biblio and authority). Is there a way to change from english to german? I have done some translation work on the descriptions of the MARC-fields too using the staff interface. Is there a way to export that for use in other installations? Thanks Beda -- Beda Szukics www.muri-gries.ch Benediktinerkollegium, Bruenigstr. 177 CH-6060 Sarnen
