That's a huge [work in progress](https://github.com/charmoniumQ/PROBE/pulls).

We're starting out with just "analysis" of the provenance. Does this input file influence that output file in the PROBEd process? Run


``` bash
nix shell nixpkgs#graphviz github:charmoniumQ/PROBE#probe-py-manual \
--command sh -c 'python -m probe_py.manual.cli process-graph | tee /dev/stderr | dot -Tpng -ooutput.png /dev/stdin'
```

## Developing PROBE

1. Follow the previous step to install Nix.
