from using over the last five years

maintained any more by the original author. Due to the
lack of regression tests maintenance and feature
additions will become very difficult.

● Coverage analysis of instructions (C0), branches (C1),
lines, methods, types and cyclomatic complexity
● Works without source files
● Support for different JVM languages
● Integrated with many popular tools
