A stupidly simple currency conversion tool.
It fetches conversion rates from ecb.int (European Central Bank), so it's accurate, too. It currently handles some 25 different national currencies.
It's built with kjsembed, so you may have to install 'kjscmd' from the kdebindings module to try it out.
It's not at all rocketly scientific, it's just that there aren't too many kjs scripts around (yet), so I figured it made sense to post it.
