To load this example and for sample queries, please see the `SCRIPT.txt`
file.

This folder contains an implementation of the classical family tree Prolog
example. This solution defines a root object, `relations`, with predicates
for common family relations like `sister/2` and `father/2`. This root object
can then be extended with objects defining the actual families using basic
`female/1`, `male/1`, and `parent/2` facts. Several family objects can be
loaded at the same time.
