================================================================= Logtalk - Object oriented extension to Prolog Release 2.16.2 Copyright (c) 1998-2004 Paulo Moura. All Rights Reserved. ================================================================= To load all objects in this example consult the ch.loader utility file (note that the *.loader files are Prolog files). You will need to also load the objects in the "roots" example. You will need to consult the following files in the library directory: events.loader, types.loader, and hierarchies.loader. Alternatively, you may load the library/all.loader file to load all library entities.
