Information is structured on 4 levels:

• the different "modules" available via icons on the horizontal band,
• each module consists of "sections" accessible through the vertical band,
• each section includes "headings" accessible by tabs under the horizontal band,
• explanatory "details" are accessible from some active words that open internal complements, external documents (pdf, Excel, etc.), or "internet" pages if you are on line.

The free selection of sections and independent headings allows an adaptation to everyone's needs. Under each heading, some details are provided on request in order to get further details with more precision if necessary.
