 =============
 2.13.0 - June 15, 2002
 	Logtalk now outputs Prolog code using write_canonical/2 instead of 
 	write_term/3. Goals are better portability of the generated Prolog files 
 	and avoid issues with clauses with long bodies for Prolog compilers that 
 	use a term print depth limit to prevent problems with cyclic terms.
 	Added report of default flag values at Logtalk startup.
 	Logtalk now prints a warning when redefining parametric objects.
 	Removed need of an abort/0 predicate from the Logtalk debugger example.
 	Removed any definition of this predicate from the config files.
 	Added missing definitions for some ISO built-in predicates to the Amzi! 
 	Prolog 6.2.2 config file.
 2.12.0 - May 25, 2002
 	New read-only Logtalk flag "version". Corrected exception term generated

-Logtalk needs access to the  predicate property<code>built_in</code> to properly compile objects and categories that contain Prolog built-in predicates calls. In addition, some Logtalk built-ins need to know the dynamic/static status of predicates to ensure correct application. The current draft for the ISO standard for Prolog modules defines a <code>predicate_property/2</code> predicate that is already implemented by most Prolog compilers. The Logtalk compiler and runtime use the <code>abort/0</code> predicate for error handling. Note that if these capabilities are not built-in the user cannot easily define them.</p>

 For optimal performance, Logtalk requires that the Prolog compiler supports <strong>first-argument indexing</strong> for both static and dynamic code (most modern compilers support this feature).
