I'd prefer using a build.sbt where possible instead of Rediscala.scala. What do you think?

[Ma27]

agreed. A build.sbt is more convenient and less verbose. I’ll have a look at it when I’m home again :-)

[kardapoltsev]

If nobody starts working on it I could try to make PR with a fixes. Has anybody already started?

[herzrasen]

I didn't start yet. Kind of busy right now. Feel free to open a PR @kardapoltsev

[Ma27]

@kardapoltsev not yet, I added you as second assignee, would be cool if you could submit a PR, @herzrasen or I could take over after some time :-)
