I did.
After that, I immediatly typed

> file_search_maxima : append
> (["/usr/share/maxima/.../share/contrib/Zeilberger"],
> file_search_maxima);

and I had success in doing

(%i2) load(zeilberger.mac);

I would like to know: this modification of
file_search_maxima is permanent or it holds just
during the current session?

Regards,
Giovanni Gherdovich
