Did you guys read the same thing I did? AFAICT it's a service for logging bugs, analysing who is most recently responsible for the bit of code at the point where the exception/segfault happened, and emailing them.
To be fair to everyone, I was initially confused, but I was able to piece together what it is. However, I'm not sure about it's scope - like if it's a general bug tracking system (as opposed to just bugs that generate exceptions or stack traces), or if it is even for features, not bugs. I think it would help the project to say these things up front.
