Obtainning sheet title inside a sheet

[Benoit Plessis <max maverick maverick eu org>]

Hi,

I need to automaticaly display and use the sheet title
inside formulas.
I stepped on <<"Sheet_Title:">> in the documentation
(http://www.gnome.org/projects/gnumeric/doc/sect-data-formulas.html)
but i'm afraid i wasn't able to use it. The best i could do
was =Sheet_Title who produced *#NAME?*.

So i grepped the source code (gnumeric-1.6.1) but i wasn't able
to find reference of this string other than in the excel import/export
plugins.

Any idea ?
Regards,
