[SLE] a way to copy evolution addressbooks

Hi, I'm wondering if anyone has a good idea to copy evolution addressbooks (plural, I created some to organize contacts) from one 10.1 machine to another, or even one user to another in the same machine. My environment is Gnome and Evolution 2.6.0. I searched the archive and found the config was under "~/.gconf/apps/evolution/addressbook". But I'm not smart enough to completely decipher the xml script in "%gconf.xml", which seems to contain the addressbook config. Thanks, Toshi
