Contur is not really in a production release, but getting close… it is open source and you are welcome to have a try with it.
Check out the contur code from our repository at gitlab.
git clone email@example.com:hepcedar/contur.git
The default branch should work with Rivet 3.0.X
The README provides some instructions. We also have a docker-based tutorial produced for various schools (YETI and MCnet) which is available here.
(needs updating for release)
