Prolog text-books give you an overview of the Prolog language. The manual tells you what predicates are provided in the system and what they do. This chapter explains how to run a project. There is no ultimate `right' way to do this. Over the years we developed some practice in this area and SWI-Prolog's commands are there to support this practice. This chapter describes the conventions and supporting commands.
The first two sections (section 3.1 and section 3.2) only require plain Prolog. The remainder discusses the use of the built-in graphical tools that require the XPCE graphical library installed on your system.
