Here is an Example System (v 4.3) that you can peruse through. Operational versions based on v3.0 are in use for Grand and Otago sinks, and we maintain one based on v2.7 for the marbled salamander. Various versions for jaguars, geckos, whale-sharks, fowler's toads and many others exist. If you would like to contribute, develop or apply Sloop? Please contact us. We would be delighted to help.
