Hello.

I have two questions:

1) I cannot load the zeilberger package. Here is the
Maxima session:

************************************************
(%i1) load(zeilberger);

Could not find `zeilberger' using paths in
file_search_maxima,file_search_lisp
 (combined values: [...])
 -- an error.  Quitting.  To debug this try
debugmode(true);
************************************************

But I'm able to normally load other packages from
maxima/share/contrib:

************************************************
(%i2) load(distrib);
(%o2)    
/usr/share/maxima/5.9.2/share/contrib/distrib/distrib.mac

(%i3) load(plotdf);
(%o3)        
/usr/share/maxima/5.9.2/share/contrib/plotdf.lisp

(%i4) load(descriptive);
(%o4) 
/usr/share/maxima/5.9.2/share/contrib/descriptive/descriptive.mac
***********************************************

I run Maxima 5.9.2, got from the "Synaptic Manager"
tool in Ubuntu Dapper Drake. I downloaded separately
(from Ubuntu system) the maxima/share directory.
How should I do?

2) I would like to know if the Zeilberger package
uses the command "nusum" when it performs the Gosper
Algorithm.

Regards,
Giovanni Gherdovich
