The Help System
This page is twofold: it documents the Help System and it gives direct access to any help files.
The selection Help on Help System introduces to the design of the Help System with 7 levels of intervention. It is shown how the Help System is subtly present on user request.
The following sections gives direct access to all help files of the website, though they are generally reachable since a more natural location: the topic pages they are documenting.
The Help System has been realized with a good quality of typesetting and presentation. The documents are interspersed with multiple examples from the website. In addition, different links allow to make the parallel between the documentation and the reality.
All the help files are pdf documents. As such, they can be saved and stored on local computers when needed.
