mutest is retired.
It was a fork of mutant project with a few misc. customizations including inline source code disables. I no longer have interest in maintaining this and it is buggier than mutant. I am hoping for some of the handful of features this added to be eventually fully supported on mutant. If you are curious about how this project differed from mutant at the time, the CHANGELOG has some context.
- Markus Schirp did an amazing job on mutant which this fork is based on.
