================================================================= Logtalk - Object oriented extension to Prolog Release 2.17.0 Copyright (c) 1998-2004 Paulo Moura. All Rights Reserved. ================================================================= To load all objects in this library consult the metapredicates.loader utility file. You will also need to load the library/types.loader file (note that the *.loader files are Prolog files). Alternatively, you may load the library/all.loader file to load all library entities. This example shows the use of metapredicates in Logtalk. Metapredicates are predicates whose head contains arguments that will be called as goals in the body of the predicate definition.
