Add chapters to Scilab help system

[José Luis Volta Grau]

Hi,
I've tried to add a help chapter for my functions to the Scilab-5.2.0 help system, as I did with version 4.1.2
But Scilab rises an error when I try to access the global constant "%helps", and nothing happens when I use the "add_help_chapter" function (my help chapter doesn't appear).
What's the difference between the 5.2.0 and 4.1.2 versions ?

I would appreciate some help,
J.L.V.
