[NTG-context] caption setup

Hello: I have to setup caption formatting for Hungarian. In Hungarian I have to write "#. figure." instead of "Figure #:" The exact word for "figure" is "ábra", so what I want exactly is: "# ábra.", eg "1. ábra". How can I do it? (If I set the document language to Hungarian, the word "ábra" is shown correctly but the order is not correct; I get ,. ábra:#.) Another question: for caption text I want it to be justified and the last line of the caption centered. How can I do that? Thanks, bcsikos
