<P>This manual describes version 5.11.18 of SWI-Prolog. SWI-Prolog has 
been used now for many years. The application range includes Prolog 
course material, meta-interpreters, simulation of parallel Prolog, 
learning systems, natural language processing, complex interactive 
systems, web-server and web-server components. Although in our 
experience rather obvious and critical bugs can remain unnoticed for a 
remarkable long period, we assume the basic Prolog system is fairly 
stable. Bugs can be expected in infrequently used built-in predicates.

<P>Some bugs are known to the author. They are described as footnotes in 
this manual.
