 - `capture-snippet.sh` - add a new snippet based off of a binary on your local machine (not recommended, but allowed)
 
 There is a `config.yaml` that tracks all binaries that the tests can use. This makes it possible to download it at any time from a hosted source. Today the only method allowed is to download a container image and extract files out.
