Virtaal - computer-assisted translation tool in Python

Virtaal is a graphical translation tool. It is meant to be easy to use and powerful at the same time. Although the initial focus is on software translation (localisation or l10n), we definitely intend it to be useful for several purposes.

Virtaal is built on the powerful API of the Translate Toolkit. “Virtaal” is an Afrikaans play on words meaning “For Language”, but also refers to translation.

Download Virtaal if you don't yet have it. The Windows setup.exe installer contains all necessary dependencies. For other platforms, ensure that you have all the other dependencies, including the newest Translate Toolkit.
