Yeah, I know, I promised that it would release only when reached the version 1.0, but a lot of people sent me mail about the bot, and I had a lot of visits on the project page from people searching for an IRC translation bot.
And you can get it now here! Download!!! Read the README file to know how to put transbot working. And after transbot join the channel that you want it to work, type !help to get a list of supported commands of the bot.
Remember: it’s open source and still on development, i.e., there are a lot of things to do on it yet. Enjoy!
