This gem downloads the exchange rates from the National Bank of the Republic of Belarus. You can calculate exchange rates with it. It is compatible with the money gem.
$ gem install nbrb_currency
Check documentation for github.com/RubyMoney/eu_central_bank, it's almost the same
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
