Allegro OpenSource: tradukisto

At Allegro we use many open-source tools that support our work. Sometimes we are not able to find what we want and this is a perfect moment to fill the gap and to share with the community. We are proud to announce an initial release of Tradukisto — a small Java library created to convert numbers to their word representations.
