Logtalk is an object-oriented logic programming language that can use most Prolog implementations as a back-end compiler. As a multi-paradigm language, it includes support for both prototypes and classes, protocols, component-based programming through category-based composition, event-driven programming, and multi-threading programming. License: Artistic License Changes: This release improves support for multi-threading programming, adds support for checking arithmetic expressions for calls to non-portable functions when using the portability compiler flag, updates several Prolog config files, includes new examples, and adds support for generating plain text files from XML documenting files. Other changes include bugfixes and improvements to library objects and text editing support.
