The typical use-case is to document the Prolog files that belong to a project in the current directory. To do this load the Prolog files and run the goal below. This creates a sub-directory doc with an index file index.html. It replicates the directory structure of the source directory, creating an HTML file for each Prolog file and an index file for each sub-directory. A copy of the required CSS and image resources is copied to the doc directory.
