More open source? Fuck yeah, more open source!
We just released the logging engine we have written Rayne under the MIT license. Say hi to ratatoskr.

What is ratatoskr? Well, it's a std::cout/printf replacement, highly customizable and made for multithreaded applications, which is where it really shines. Oh, and it allows you to create your own custom logging engines, for example like the one we use in Rayne to create HTML based logs!
