revzip - don't understand how to use it...

[runrev260805 at m-r-d.de]

Hi,
 
can someone help me with revzip?
 
I want to update a file to an existing archive or, if the archive does not exists, create the archive and add the file.
 
I read the documentation about revzip, but don´t understand what exactly i have to do.
 
Regards,
 
Matthias
