# relations

This folder contains rewritten versions of some objects provided  with
previous, 1.x versions, of Logtalk. They are intended to  help the
conversion of applications from Logtalk 1.x to 2.x and to support most
of the other examples provided with the current Logtalk package.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Start by loading the example and the required library files:

```logtalk
logtalk_load(relations(loader)).
```

The objects in this example are used by several of the other examples.
