Hmmm... for me, the search function on http://maemo.org is kind of broken...regardless of which category I choose, the searches only take place within the "Maemo.org documenation" section. Since the currency convertor isn't officially blessed by Nokia, it won't show up there.

A search within the "garage.maemo.org" section should return a link to the Maemo garage site for the currency convertor, and a search from https://garage.maemo.org does work.

I really do need to investigate the mechanism for getting the gcur package included in the "maemo extras" repository....
