+SUMMARY="SWI Prolog. Stable and free standard Prolog implementation"
+DESCRIPTION="
+SWI-Prolog is an open source implementation of the programming language Prolog, \
+commonly used for teaching and semantic web applications. It has a rich set of \
+features, libraries for constraint logic programming, multithreading, unit \
+testing, GUI, interfacing to Java, ODBC and others, literate programming, a web \
+server, SGML, RDF, RDFS, developer tools (including an IDE with a GUI debugger \
+and GUI profiler), and extensive documentation.
