caracat (always in lowercase) is a port of caracal from C++ to Rust.
The initial motivation was to benefit from a saner build system to make the project easier to maintain. The architecture is very similar between the two projects and the input/output format is the same. Versions > 1.0.0 might break this compatibility to fix some idiosyncrasies inherited by caracal.
Multiple example binaries are provided:
