---+ SWI-Prolog XREF --- Cross-Referencing Tool
The SWI-Prolog Cross-Referencer can be used to examine the currently loaded program, creating a hierarchical file overview with icons indicating which files have suspicious code, a dependency view as shown below and detailed info per file as shown below that. To analyse a program, load it into Prolog and, simply run gxref/0:
---++ XREF - Dependency

File-dependency view. Views can be created for the whole project, per directory or selectively by adding files to the view.
---++ XREF - File info

Provide information per file on its dependency. Using the command 'Header', the system can create module headers with appropriate import and export headers.
